Open intercom metacon without a key. A guide for those who have a bad memory: how to open an intercom without a key

User manual.

Introduction.

The digital intercom is specially designed for multi-family residential buildings. The intercom consists of two main blocks - a digital panel and a processor with a power supply.

The main features of this model:

Numeric panel without mechanical switches. This solution provides a high degree of protection against the most common problems such as contact oxidation, sticking and button blocking.

Two-wire scheme for connecting subscriber devices (tubes) (hereinafter referred to as AU). The number of AUs is up to 255.

The processor has a built-in controller that allows you to open the door using the TOUCH MEMORY and TOUCH CYFRAL keys. Memory capacity - 508 keys

The front door can be opened without using a key, as each apartment has a separate 4-digit code for opening the door.

The ability to programmatically change a large number of different system parameters allows you to configure the intercom in accordance with the wishes of specific users.

Intercom installation.

Network connection.

After checking all the connections, you can start connecting the power supply. After the power is turned on, a dot appears on the right indicator of the panel and a countdown of 25 seconds begins. After the countdown is over, the intercom is ready for use. After each subsequent inclusion in the network, the countdown must be turned on again.

When turning on for the first time, it is imperative (and at subsequent ones to cancel programming errors, if any) closer to the end of the countdown, simultaneously press + <Ключ>and hold until rapidly changing numbers appear on the display.

Checking the correct voltage between the contacts.

		100 mV less than K1 - K3
		6 V, when talking 4-5 V

Deviations within 20% are allowed.

Indication of errors and defects.

The messages below indicate malfunctions.

If one of the infrared rays of the panel “fails”, then the intercom program ignores the failure and continues to work. The display signals this with an “E” sign on the left indicator.

If more than one beam fails, the display will show “Err” and the keyboard will turn off. According to the program, in case of serious malfunctions of the panel, the intercom will silently turn the lock on and off every 45 seconds (after several tens of minutes after the malfunction is detected).

The message “E-2” indicates a short circuit in the line or a malfunction of the off-hook AU.

The message “E-0”, which appears after connecting to the network, indicates failures in the RAM of the microprocessor. If this symbol appears, the intercom must be replaced.

Sound adjustment.

In total, the intercom has 3 adjustments:

Boosting the microphone signal

Amplifying the speaker signal

Linear balance

The intercom is already adjusted when delivered, but may still require further adjustment.

In order to correctly set the balance, an AU located approximately in the middle of the line length should be selected. Then, making adjustments, you need to find and set the point of minimum excitation as follows:

Adjust the level so that conversations can be heard.

By adjusting the balance knob to one side, find the position where the device is excited. Then find the same position by turning the balance knob in the opposite direction.

Set the balance control to the middle position relative to the two found points.

Gradually increase the level.

Repeat steps 2 - 4 until the best balance control position is found. In the maximum sound level position for both talk lines, it is impossible to adjust the balance due to excitement.

This sets the sound level. However, be aware that if the gain is set too high for individual talk lines, excitation due to acoustic feedback may occur. It is recommended to set the optimal level as follows. Set the bottom-up gain to the lowest possible level, which ensures acceptable audibility from the AU. Set the “top-down” gain to the maximum possible, and then turn the reward knob down.

Intercom operation.

Connection of apartments.

When dialing the apartment number, each touch is accompanied by a sound signal and the appearance of a number on the display. Each next digit of the apartment number should be pressed with a pause of no more than 3 seconds.

If a number greater than 999 is entered, it is canceled and the next digit is determined as the first digit of the new number.

If the pause between presses is more than 3 seconds, then the intercom determines the completion of dialing and establishes a connection with the selected apartment.

If you make a mistake while typing, press and repeat set.

Before the connection is established, the intercom determines if the apartment number is on the allowed list. If the apartment is excluded from the allowed list, the display shows “OFF” signal and an audible signal sounds. After establishing a connection with the apartment, a 30-second call tone sounds (default setting). After that, the system waits for another 30 seconds to go off-hook. When the AU handset is removed, two-way communication is established.

By pressing number is reset.

The duration of a conversation with the apartment is limited to 2 minutes (default setting).

The electric lock can be turned on at any moment of the conversation by pressing the button on the AU. The lock opens for five seconds (standard setting). Opening is accompanied by a sound signal. All times mentioned above are subject to change. Communication with the apartment is terminated if you hang up the AU.

Using the lock code.

Residents can open the door with a code. The code can be changed by the tenants themselves (see instructions below).

To use the code lock:

Dial the apartment number

Touch the "Key" field. Three bars will appear on the display.

Enter four digits of your code.

After entering the correct code, the lock opens. Opening the lock is accompanied by a sound signal in the apartment (if this function is not canceled in advance).

The intercom comes with a code table. These codes are selected by the computer in such a way that each apartment has its own code combination.

Changing the lock code by tenants.

To change the code:

Dial the apartment number.

Wait for connection.

Touch the Key field.

While continuing to keep the “Key” field pressed, ask the subscriber in the apartment to press the door opening button three times. Each press will be accompanied by a beep.

Three bars will appear on the display - the lock code symbol.

Release the "Key" field and enter the old code.

If the old code was entered correctly, the intercom is ready to enter the digits of the new code. The number of the entered code digit (1) and a dash will appear on the display. Press the button with the first digit of the new code, and it will also appear on the display. After about 1 second, the number 2 will appear - press the button with the second digit of the code, etc. up to 4.

During this procedure, the AU tube must be removed. Do not press the door open button.

Using KeysTOUCH MEMORY.

Residents can open the door with TOUCH MEMORY keys (an electronic key is a tablet with an individual code). When the key is touched to the reader, this key is searched in the intercom memory and if the key is found, the door opens. The keys are written to the intercom memory using the MASTER KEY (see the Programming Manual).

Programming instruction.

The instructions use the following symbols:

The parameter shown on the display;

- entered parameter (single character);

- simultaneous touch to two fields;

/Sv/ - sound signal.

To memorize the characters displayed on the display, use the "Key" field.

If no new digits are entered, pressing the “Key” field returns the program to its original state.

A time interval of 45 seconds is allocated for selecting a service procedure. If during this time the procedure is not selected, the intercom exits the programming procedure to its original working state. You have 6 seconds to enter the parameter in the selected procedure. If no new data is entered within 6 seconds, the system returns to level .

It should be remembered that before operations with the apartment (changing the code, turning off the AU), you must first dial the AU number taking into account the offset.

Access procedure.

<Ключ> [---] <240361>/Sv/ /Sv/

where - the personal code of the intercom installer, and 240361 - the general code determined by the manufacturer, the same for all intercoms of this model. The installer code is a number in the code table and can be changed in the appropriate procedure. After the installation and personal codes have been entered correctly, the message will appear on the display, the programming mode will be switched on and the communication mode will be switched off.

Installer procedure 0 - opening the electric lock.

<0>/Opening the lock/

The procedure should be used when installing the intercom to adjust the electric lock.

Installer procedure 1 - Main installation procedure.

With this procedure, pressing the door open button on the AU can initiate top-down communication. After that, the intercom detects this AU and establishes communication with it without a sound signal. In this case, you can start a conversation or open the lock. After the handset of the AU is put on the hook, the intercom again communicates with this AU for control. The display shows the apartment number.

AU search is carried out in a certain range, for example, from the first to the last apartment on the floor. This reduces the time required for the intercom to search for the AU and prevents interference from other AUs out of range. Do not set too large a range (no more than 20 numbers), because when searching for an AU with an off-hook, all AUs with lower numbers (within the specified range) are connected to the communication line, which interferes with the normal search for the desired AU.

<1>/Pressing the AU button/ /Sv/ [Apartment number, if the corresponding AU is found]

Using this procedure, you can set the highest and lowest search levels (limits)

bottom line - ;

upper bound - ;

or [previous border] <Новая граница> <Ключ>

In order for the intercom to accept values, the upper limit must be greater than the lower one.

Limit numeric values ​​are NOT retained when power is turned off. When the power is turned on, they are set: lower - offset + 1, upper - offset + 254.

To exit the procedure, press , after which the program will return to the level .

Installer procedure 2 - Setting the intercom parameters.

This procedure is used to set the door phone parameters.

The level has 9 sublevels. The first 8 are used to enter temporary parameters, 9 - to enter configuration flags, in turn also has 6 sublevels.

Time parameters:

	Name		Value by mind.
	AU call time on-hook
	waiting time after call
	negotiation time
	lock opening time
	call time
	first call tone
	second call tone
	time for one tone

Setting the time parameters:

<2> [_] <Номер параметра> <Ключ>[Parameter set value] [New parameter value]<Ключ> [_] <Другой номер параметра>or<Ключ - для выхода>

After entering a new parameter, it is compared with the maximum allowable value for this parameter. The maximum values ​​are shown in the table. An attempt to enter large values ​​is ignored.

The tone frequency is determined by the formula

F = 333333 / (256 - parameter value).

For a single tone time of 1 second, the parameter value is 150.

Configuration flags:

permission for a special procedure (opening the lock in case of a short circuit in the communication line);

authorization for a special procedure via Err (opening the lock in case of panel malfunctions);

permission for the passage of residents by code;

display output resolution E (if one beam of the keyboard fails);

permission to confirm the code (call back to the apartment when passing through the code);

permission to call the AU with the handset raised;

Configuration rules:

<2> [_] <9> <Ключ> [_]<Номер параметра от 1 до 6> <Ключ>[-1-] if enabled or [-0-] if disabled<1 или 0> <Ключ> [_] <Другой номер параметра от 1 до 6>or<Ключ - для выхода>

All parameters set by this procedure are stored in memory and are not erased when the power is turned off.

Installer procedure 3 - Utility program.

This procedure checks for AU programming errors.

Enter apartment numbers (up to 15 numbers). After entering the last number, the intercom will return to the normal working state. However, starting from this moment and within 45 minutes, the intercom can be called from these AUs by pressing the door opening button. At the same time, the intercom establishes communication with the AU with the number specified in the list and the handset is lifted.

Applications.

Connection diagram.

Connection of the panel, lock, contactor and button is made with a 12-wire wire. The wire length should not exceed 30m. Contact R2 must be connected with two wires to avoid voltage losses at the lock.

Intercoms and video intercoms Metakom are products of domestic production. This equipment is distinguished by its practicality and reliability in operation. The device is designed specifically for apartment buildings: it is multi-subscriber and is able to combine up to 999 subscribers into a system. To open the front door, intercom keys Touch Memory and Touch Cyfral are used. Sometimes they can be lost or broken, and in such cases the question arises of how to open the Metakom intercom without a key by learning three secret digits from a list of predefined codes.

The intercom consists of processor and digital parts. The processor part of the mechanism contains a power supply. The device's numeric keypad (with or without a screen) does not have mechanical switches. This avoids many equipment malfunctions. Security systems can be opened not only by means of identifiers, but also by means of special codes. The question of how is quite relevant for those who have forgotten or lost the key. From the video below you will learn about programming the master key:

Using special codes to gain access to the premises

To open the Metacom intercom, it is more expedient to use a key designed for this purpose. In life, there are various situations when the necessary identifier is not at hand.

It is possible to select digital combinations for access only in exceptional situations: in no case should such information be used for personal gain.

How can I find out the code for keyless entry? As a rule, all codes are programmed during the manufacture of the mechanism and throughout the entire period of operation they do not change. An exception is the case of changing the programmed password during installation work and. But if the passwords still did not change, then you can try the following steps step by step:

1. On the calling panel, press the call key;
2. Enter the serial number of the first apartment in the entrance;
3. Press the Call button;
4. After the appearance of the inscription Cod, enter the password 5702.

Depending on the functional features of a particular model, it may be different. In this case, you can try the following combination: enter the code 65535 on the call panel, press the “call” button, then dial 1234, then the “call” key and the number 8. Also in practice, this dialing option may occur: 1234, the Call button, number 6, call key, digital combination 4568.

If the indicated digital combinations did not work and the door did not open, then you can try to apply another code from the intercom:

• On the panel, press call, then enter a combination of numbers 2 and 7;
• Then the call is pressed again and the code 5702 is entered.

There are situations when a new identifier was made, but it does not open the door, because it is not programmed in the intercom device. For its programming, it is not necessary to resort to the help of specialists, because you can configure it yourself. To do this, press “call”, number 1, “call”, digital combination 4526 on the call panel. Then a new identifier is brought to the reader, and it is automatically entered into the system memory.

Programming the device to work in encoding mode

To open the front door, sometimes it is not enough to perform the above actions. The reason for this may be a change in the programmed password, and features of the equipment model range, and incorrect performance of any action. Most often, the error occurs due to the functional features of the installed equipment. For some models of intercoms, entering a new key into the memory of the mechanism may occur differently. For example, you can apply the following scheme: on the call panel, dial the numbers 65535, call, 1234, call, number of the desired apartment, call, number 7. The introduction of this combination allows you to save the apartment number in the memory of the mechanism.

To delete all, the following algorithm of actions is used: enter password 65535, call, 1234, call twice, number of the required apartment, call, 70111. For some models, the cipher from the Metakom intercom to record a new key may look like this: 65535, Call, 1234, Call, 9-9. If you enter the combination 990111 instead of the pin code 9-9, then the saved key will be deleted.

Photo of a calling panel without a display It is generally accepted that the settings catalog in Metacom intercoms is divided into 3 separate branches: service, system and user. In this case, each will perform certain functions, and with their help you can only change specific settings. To open the system menu, dial the digital combination 65535, call, 1234, call and number 9. To gain access to the service menu, you need to perform the same steps: repeat the previous combination, except for entering the number 9. To display the user menu, enter the code 65535 on the digital panel , press the Call button, 1234, then the call button twice.

To exit the program mode, press and hold the door release button.

Special codes for keyless access in practice are called master codes. All of the above combinations, as a rule, are working. But it is worth paying attention that during installation, specialists often change them to ensure security and the impossibility of access to the entrance without using a key. If the use of codes did not lead to the opening of the intercom, then you can use other methods. For example, call any apartment and introduce yourself as a social worker or wait for someone from the residents of the entrance to leave.

What to do if you still do not understand how to find out a special cipher for access, and all of the above combinations do not work? Another effective way is to purchase a universal key. In appearance, it is identical to the keys that complete the equipment, but it allows you to open several types of intercoms within the same model range at the same time. Perhaps the acquisition of a universal master key is a more acceptable way than opening doors by selecting special codes.

On the video - changing the master code of Metakom intercoms:

Now it is difficult to find a house that is not protected by a special system. This wonderful device warns against uninvited guests. But what to do if you forgot the magnet at home, or it stopped working. If this happened during the daytime, you can wait until the neighbors open the door. What if at night? How to open the intercom without a key in this case? We have collected the best tips for resolving this annoying problem, depending on the make and model of the intercom. Enjoy!

An intercom system is a security measure that is applied to. It is used to connect the guest with the owner and is installed in apartment buildings or offices.

It can be used to solve a wide variety of tasks:

• the simplest system will help organize the entrance of clients to the organization or guests to private housing;
• organize a more complex system and the ability to record the history of events;
• additional device .

For all the time of using intercom systems, no one doubts their effectiveness. The issue of choice is a financial issue.

The principle of operation of the intercom system

The device is quite simple and consists of only a few components:

• call block. It is presented in the form of a panel protected from dust and moisture penetration;
• inner zone, which includes intercom(call key, microphone and loudspeaker) and door station;
• latch lock;
• subscriber complex. It is made in the form of a tube and is installed either at the reception in the office. On it are located: control button, microphone and speaker;
• magnet with chip.

The intercom can be provided with an audio or video signal. All elements are connected through a switch.

The intercom device works by analogy with a relay connection as follows:

• the guest presses the "Call" button on the external panel;
• contacts are closed, the signal reaches the subscriber complex of the owner;
• the host of the receiving device presses a button to negotiate;
• by the decision of the owner, he can, by pressing a button, unblock the entrance system or refuse to accept.

Manufacturers initially set a password to open the door mechanism. When installed at the request of the owner, it can be replaced either on the main unit remote control or through software.

How to open an intercom without a key: basic methods

If you didn’t have a magnet with you, or it stopped working, you need to contact your familiar neighbors. You just need to dial their number on the device and explain this trouble. If they are at home, they will certainly provide access to the entrance.

But this situation does not apply to all cases of life. For example, appliances are not installed everywhere. Or the systems are off. In this case, you can knock on the windows of the neighbors on the first floor. The owners will understand the huge problem and help unlock the system.

And if you are the owner, and you simply do not have neighbors? Or another option - you returned at night, and calling someone is simply indecent? In this situation, code should be used.

No need to try to enter the entrance by force or break the dashboard. This will not help unlock the lock. In addition, the doors in this case are not unlocked from the inside, and you will have to pay for the repair of both the door and the intercom system. Even administrative penalties for petty hooliganism can be applied.

Universal key for intercom: do it yourself

Several options for keys are produced for modern intercom systems. Their main task is to open the entrance lock with the established protection control. All of them are programmed with a specific factory code. If the firmware was changed during operation, in this case only the service department can help unlock the system. After their intervention, it will be necessary to re-program the device.

Firms that are engaged in programming locks use a special technology for opening devices:

• contactless;
• tablet-chip;
• all-terrain vehicle;
• universal key for intercom.

With the help of the latter, you can open up to 95% of the models. It is convenient to use, as with its help you can quickly solve the issue of opening doors. It is these devices that are used by service workers or postal workers.

The key called "all-terrain vehicle" can also be attributed to the universal ones. Utility workers may not be carrying around large bundles of chips. It is enough to have one universal. The programming device is located in the chip, it is enough to attach it to the contact located on the input panel.

There is another way to open intercom devices using a universal key - a contactless master key. To do this, there is no need to apply it to the contact on the panel. The principle of operation is at a distance. She has one significant drawback - high cost.

How to make a universal device yourself

Such a device is not difficult to perform for someone who is familiar with programming and has the skills of a radio mechanical engineer. You need to know the name of the model. Information about which blank is suitable can be found on the Internet. There are also tables for combining the duplicator and blanks.

Making a new device takes a few seconds. To do this, you need an “emulator” device. This is a device that opens almost all intercom systems, with a few exceptions.

But even the most professional wizard, the best software and emulator may not be able to handle some devices. It is necessary to personalize the emulator for a certain version, then the cipher will be easily selected for this model.

How to open an intercom from well-known manufacturers if you forgot your keys

An excellent solution to the problem of how to open any intercom is a password. It is installed in the firmware. It should be clarified with the workers who were involved in the installation of the intercom device, or found on the Internet.

The same cipher is suitable for many devices from different manufacturers. This applies to devices Vizit or Eltis . But for the new system Cyfral no password provided.

It is important! The password embedded in the program of the intercom device works even if it is deprived of a memory card.

In most cases, if the codes are programmed by the manufacturer, the passwords can work in all cities. Sometimes intercom systems can be encrypted by the installer company. Then you need to ask for a password from them. In any case, services that require the daily opening of systems, such as postal workers, have a code. You can check with them the password from the intercom device.

How to open the Vizit intercom without a key

This is the most common system. If the original firmware has not changed, the algorithm for how to open the Vizit intercom is as follows:

• 12#345;
• *#3423;
• *#4230.

For new devices "Vizit" will suit:

• 67#890;
• *#423.

You can use the following codes to open the Vizit intercom without a key (suitable if it has not been opened before):

• #999 - double ring, then the service panel code 1234. If this dialing does not work, there will be a double beep. If all is well - one beep.

If the service cipher is incorrect, we dial not 1234, but the following options:

• 0000;
• 3535;
• 9999;
• 12345;
• 11639;
• 6767.

To determine whether the cipher is correct or not, the beep will help: if it is wrong - 2 beeps, for the correct one - only 1.

When the menu worked with one call, you need to add your own code:

• to operate the lock: 2 - pause - # - pause - 3535;
• then you should add your own password: enter the number 3 and lean the chip from the panel, then # and wait for the sound of the lock.

Important! You must remember to delete all settings from the service settings memory. To do this, press 4 # *.

How to open the Forward intercom without a key

Manufacturers of these models often do not make their information publicly available. Only three sequences are known:

• 123 * 2427101;
• K + 1234;
• 2427101.

To include your password in the service settings, you must enter:

• 77395201 + * +0 *, put the chip against the device and press # twice.

If this sequence did not work, you can dial 5755660 instead of 77395201.

Intercom "Cyfral": how to open without a key

These are the most modern intercom models. If you don’t know how to open the Cyfral intercom without a key, then you should follow the following algorithm. It will work if there are apartment numbers in the entrance that are divisible by 100.

To open the Cyfral system, you must press:

• "B", apartment number, which is divided by 100, then again by "B" (for example, B400B);
• then 2323. If it doesn't work, press 7272 or 7273 instead of 2323.

The question may still arise, how to open the Cyfral CCD2094 intercom. It opens a little differently:

• "Call", then 41, or 1410, or 07054.

If the system did not work, you should continue in this way:

• "Call", then 0000.
• if we hit the "Menu", but the doors are still closed, you should press the number 2.

If there is a problem, how to open the Cyfral CCD 20 intercom, all the methods listed above are suitable for solving it.

How to open the Eltis intercom without a key

It is quite difficult to work with this system without a chip. The password may not be suitable for all devices. The algorithm of actions is as follows:

• V 100 V 7273.

Alternatively, we enter not 7273, but 2323.

Another way to open the Eltis intercom without a key: the technique used for the Cyfral model is suitable

How to open the Factorial intercom without a key

Factorial models can be opened by dialing 000000 or 123456. Alternatively, dial 5 and hold until a text message appears on the dashboard. Then you should enter 180180 and "Call".

This is the rarest device in terms of encryption without a passkey. The procedure is as follows:

• K - 100 - 789 - short beep - 123456 - 8;
• K - 170862 - short beep - 0.

Difficulties with the Blink system

Unfortunately, there is nothing to help in this case. These are not access intercom systems, but individual ones, which are produced for individual houses or houses with a concierge. There is no universal code for such a system. For assistance, contact the service department.

Codes for the device "DomoGuard"

This is a fairly rare model. To open, you need to type:

• "C", beep, code 669900 and "Call", then the number of the last apartment in this entrance +1.

The display should show "F-". We get into the service settings. After that, you need to perform the following algorithm:

• 080 - open the lock;
• 333 - remember the password;
• 071 - turn off automatic locking.

Intercom system "T-Guard"

For this model, the following algorithm should be performed:

• on the panel, press "Call" or "Call", enter 00000, twice on "Call".

All actions should be performed at maximum speed, otherwise the intercom device will not work.

Rainmann system

To activate the device, you need to dial:

• "Key", code 987654. After the call, dial 123456.

If everything is correct, we got into the service menu, the P icon will appear on the display. To unlock and open the lock, press 8.

How to open an intercom without a Metakom key: codes

This device will fit the following:

• "B" (CALL) - the number of the first apartment in the entrance - "B". "COD" will appear on the panel. Further 5702;
• 65535 - "B" - 1234 - "B" - 8;
• 1234 - "B" - 6 - "Call" - 4568.

For "Metacom-20 M / T" the following combinations are suitable:

• "B" - 27 - "B" - 5702;
• “B” - 1 - “B” - 4526 - then for programming, lean a clean key (not previously programmed) against the dashboard.

Conclusion

The proposed options, how to open the door without an intercom key, can be applied if the manufacturer's primary parameters changed during installation. In addition, it is important to know which manufacturer's device is installed in the house. The use of these algorithms can be used in the rarest cases, their use for selfish motives can be criminally punishable.

In this video, tips are shared by professionals.

Manufacturers of such locks are developing new security systems, improving already released models.

General concepts about the intercom "Metacom"

This lock consists of several components: a processor with a power supply and a digital panel. It opens with a key-identifier. It is enough to bring the key to a special contact point on the intercom. The process of its use is built on the exchange of data in microcircuits and the memory of the key and lock. The chip contains code information that opens the door. This code is not subject to change throughout the entire period of operation. All keys developed by Metacom are designed to work exclusively in this system, have a durable case and shock protection. The master keys withstand temperature fluctuations from -40С…+75 ºС, they are not affected by the electromagnetic field. In the event of a broken key, it is possible to repair it.

Two types of keys have been developed that can accommodate up to 508 types of identifiers:

• touch memory;
• TouchCyfral.

In addition to using an identifier key, it is possible to open the lock using a special code consisting of four digits. The owner of the code can change the settings of the software by changing the code to any desired combination.

There are also contactless master keys, which are produced in the form of plastic cards or key fobs. The production of such instruments is carried out according to the Em marine system and is used in the Proximity systems.

How to Change Device Settings for Keyless Access

In the case when it is necessary to register a new identification key in the system, you must use the following scheme.

In order to erase all programmed identification keys from a specific apartment from the device memory:

1. Call key.
2. Code combination 1234.
3. Call key.
4. Call key.
5. Dial the apartment number on the device panel.
6. Call key.
7. Dial code 70111.

To write the apartment number to the device memory:

1. On the intercom display, dial the code combination 65535.

1. Call key.
2. Dial code 1234.
3. Call key.
4. Dial the apartment number on the digital panel.
5. Call key.
6. Press the number 7 on the digital pad.

To delete a saved ID key:

• Call key.
