A rack and pinion lock is an overhead mechanical lock that has one or two bolts for locking. Of course, two crossbars are better, but in terms of the degree of secrecy and burglary resistance, these mechanisms, invented back in Soviet time, leave much to be desired.

In principle, the operation of the lock is quite simple. On the main bolt, the milling cutter cut oblique grooves at a certain angle, which coincide in location with the teeth on the key.

When the key is inserted into the keyhole, it engages with its teeth on the grooves of the rail and, under the pressure of the rail, moves aside and the door opens.

Rack locks They are absolutely unpretentious, they work well both at sub-zero and positive temperatures, they tolerate humidity and precipitation well, but due to their low burglary resistance, they are not recommended for installation in apartment doors.

However, for installation in a wicket or garage door, it is the best fit, especially if you combine it with a mortise safe.

Locks are installed in an overhead method, on outer surface garage doors, fastened with screws or bolts.

There are legends about the service life of these mechanisms, they practically do not break, because springs and levers are completely absent in the design.

Methods opening locks crossbar type are quite primitive, universal and boil down to one thing: you need to move the slats one by one. Let's consider several ways:

  • Open the rack lock with a guitar string or fishing line.

First, we squeeze the door with a crowbar or a screwdriver, which we insert into the gap between the door and the jamb. From a guitar string or fishing line we make a loop, which we push into the keyhole, circle it around the pins (with which the lock opens from the inside) and gently pull towards ourselves. At the same time, the slats move aside and the door opens.

  • Open the rack lock with a carrot or pencil

First, grease or spill the WD-40 lock, then release the bolt by slightly pressing the door against opening and carefully drive a carrot or softwood pencil into the keyhole. Thanks to the soft material, the teeth of the bar will leave corresponding grooves on the carrots or wood and the lock will open.

  • Opening a rack and pinion lock with a screwdriver, awl or crochet hook

We press the door with our shoulder in the direction of opening and move one prong or notch at a time with a screwdriver, an awl or a hook along the crossbar. When the upper crossbar is open, we block it from closing with a match or whatever is at hand and go to the lower crossbar. Gently move under the parallel position of the upper crossbar and push the door.

  • How to open a rack and pinion lock with a drill and screwdriver

Open the rack and pinion garage lock or metal door possible with a drill without damaging the door leaf.
First, push a sheet of paper between closed door and a box, we determine the location of the closed transom. Then we drill small holes in the box and use a screwdriver (or two, depending on the lock model) to move the bolt.

Rack wrenches

Nowadays, it is quite problematic to find a workshop that makes duplicate rack and pinion wrenches. This is due to the fact that rack and pinion wrenches are quite difficult to perform due to a certain angle of cutting of the teeth and manual adjustment to the original. The crossbar key also belongs to the category of non-standard ones, it is rather difficult for it to find a blank.

The rack wrench is divided into two main types: with a round and a flat blank. In turn, the key blank has a thread on one or two sides. A huge disadvantage of these keys is that they are very long and heavy, and the cost of a duplicate is quite high.

The situation when you have to break or open a lock on a garage door is known firsthand to many garage owners. First of all, we are talking about non-electrical systems. There are no eternal mechanical locks in nature. As dust accumulates, grease polymerization, wear of rubbing surfaces, the drive mechanism locking device can jam in the closed position, and then you have to decide difficult task- how to open a garage lock.

Ways to open a garage lock

There may be several reasons why the lock mechanism cannot be opened:

  • The secret or the blocking part of the lock device does not open due to the ingress of frozen water;
  • The mechanism is jammed due to wear of parts or secret elements;
  • The lock device is damaged when trying to open or hack the mechanism, including as a result of the actions of intruders;
  • Lost keys.

The first and last cases are the most common, so you should not try to break the lock right away, as in the video:

There are many ways to warm up a mechanism, look for keys, and open a garage lock without a key.

In some cases, if the locks are very complex, or are installed effective secrets, attackers deliberately disable the lock in the hope that you yourself will open the garage lock, and during the period of time until the new mechanism is installed, it will be possible to enter the room.

Opening garage systems

It's useless to fight and try to pick a jammed lock standard methods, for example, selection of keys and master keys. If the key blank for your garage lock is "dead", and there is not even a backlash and a hint of movement of the mechanism, then the parts are "soldered" by frozen water and jammed.

Advice! Do not try to warm up the lock by pouring alcohol, vodka or gasoline on it. In the most exceptional cases, you can try to warm up the padlock with a homemade torch made of paper or rags.

The lock can be warmed up with a hairdryer or a balloon burner, with periodic tapping with a hammer on the steel surface of the garage door in the area where the body is installed. If the inner lock is jammed, you will have to do an autopsy with cutting out the locking elements.

Lock picking methods

Most often, you can open a garage lock in one of the following ways:

  1. Mechanical cutting of the fastening of the lock. In this case, you have to drill out the welding points of the attachment or body, cut the edge of the garage door and locking cylinders, or drill out the secret;
  2. A lock pick or a similar device. Opening the secrets of garage locks with such tools is much easier than the doors of apartments. Therefore, even with minimal practice, knowing the principle and procedure of actions, it is not particularly difficult to open a secret;
  3. Autopsy and destruction of the secret of the castle. It is the least traumatic and quick way open a jammed lock. After removing the secret, as a rule, it is possible to unlock the mechanism and open the door. Changing the secret is cheaper and faster than buying a new mechanism.

Very often, the cause of the mechanism jamming is the use of inappropriate types of lubricant or problems with the installation of garage doors. For example, if instead of graphite lubricant or lithol, the mechanism is lubricated with solid oil or working off, in about a month and a half, the process of corrosion and chemical welding of parts will begin. The surest way to damage a garage door lock is to lubricate it. sunflower oil or any food type fat. It is almost impossible to open the mechanisms of garage locks in such cases.

How to open a jammed garage bolt lock

Until recently, this was the main garage lock. Thanks to a simple device, almost every mechanical processing enterprise in the USSR was engaged in the manufacture of such structures. At the heart of the locking system, a slider with oblique grooves was used, the slope and shape of which corresponded to the cut on the key. It was enough to insert the key into the key hole and press down hard. The force was transmitted to the slider, and the locking tongue was retracted to the side, compressing the return spring.

It is very easy to open a working lock mechanism with an ordinary slotted screwdriver. The tip of the screwdriver is put into the keyhole and with force squeezes the slider in the direction of opening, while it is necessary to simultaneously press the garage door leaf in order to block the action of the return spring. The autopsy takes 10-15 minutes.

The disadvantages of crossbar locks include a high probability of jamming the mechanism, as in the video:

Opening lever garage locks

Opening more complex lever systems can be performed even faster than rack or girder structures. In 90 cases out of 100, a garage lock of this type is opened with two L-shaped master keys in the following order:

  • The first pick is inserted into the keyhole, and with opposite side from the exit point of the locking cylinders, you need to grope and block the bolt plate in a stationary state;
  • With the second master key in the central part of the lock, grope and lower each lever plate down until it clicks, thereby releasing the protrusion of the bolt blocking the movement;
  • It remains to release and move the cylinders to the extreme position to unlock the garage door.

The autopsy technique is described very accurately on the video:

How to Pick a Cross Key Lock

If a cross-shaped key is used in the construction of the lock, the secret can be opened in three ways. The simplest is the usual reaming with a carbide drill or turning the body of the secret with a thief's device - a turning key. In this case, the pins are destroyed and the sockets in which they are installed are broken off. Such an autopsy is tantamount to the destruction of the castle itself.

In this article we will talk about the so-called rack and pinion locks, about their structure and the problems associated with them. We emphasize that our company does not sell or service rack locks (we do not make keys either), but comprehensively solves issues related to the replacement of these locks.

The origin of rack and pinion locks

To be honest, we have not been able to find information about the origin of the rack-and-pinion lock. On some sites they write that the origin goes as far back as ancient Egypt. We strongly doubt it, but we will not dispute it.

We assume that rack and pinion locks could have arisen during the period of industrialization. When people began to work en masse on machines and process metal in commercial quantities. But, alas, we do not have a definite answer when the locks appeared and what caused them to appear. Do you have it - write in the comments.

So what is a rack and pinion lock?

This is a lock that does not have a secrecy mechanism, and locking is provided by spring-loaded bolt strips of a certain shape. The bolts of such a lock are controlled from the inside with the help of handles. The handle is a screw screwed into each bolt, for which the bolt stupidly moves in the direction of opening, overcoming the force of the spring.

The bolt of the rack and pinion lock is operated from the outside with a rack wrench. We call it a helical toothed river. The key of a rack and pinion lock is either simply inserted and crushed into the hole of such a lock from the outside. Or it can be inserted and removed by itself, if it is a rack and pinion reverse lock.

Castle construction

The structure of a rack and pinion lock in the overwhelming majority of cases is very primitive.

The lock consists of a body, some form, which is mounted on the door. Bolts protrude from the body, there are holes for fastening the lock, as well as a through key hole.

There are crossbars inside the body. That is, these are metal sticks, which actually lock the door. The locking rails of the rack and pinion lock are spring-loaded and always strive to leave the case to the maximum distance available by design.

The locking rails of the rack and pinion lock have grooves, that is, recesses located at an angle relative to the bolt motion vector.

Well, the last component of this type of lock is the key. The key is a stick of a certain shape. It can be round, square, rectangular, or hooked if it is a rack and pinion backstop.

The keys also have parallel grooves at a certain angle. Depending on the specific lock, on the preferences of the master or the manufacturer who produced it, the grooves can be located at different distances from each other, have different width and depth, as well as their number may be different, depending on the design.

Principle of operation.

The movement of a rack and pinion key in the lock is strictly limited by a through key hole, it can only move forward and backward. Either to yourself and from yourself.

When the key is exposed, it rests against the locking rails. Now, if we press the key further into the well, overcoming the force of the bolt springs, the projections of the rack and pinion key will engage with the grooves of the rails inside the lock. Pressing the key further, you will move the bolts of the rack and pinion lock with it according to the principle of a slope from an ice slide. At the moment of disengagement of some protrusions, others will engage, as in a kind of rectangular gears.

And this will continue until the bolts completely enter the case by opening the door. At the same time, the key will rest and will refuse to go further into the well. Removing the key from the well, as you probably already guessed, will be accompanied by the release of the bolts from the body.

And finally, the crossbar of the rack and pinion lock from the outside into the case can be bluntly crushed with your fingers, and then you can close the door. As soon as you slam the door so that the holes in the box are under them, the bolts, under the action of the springs, will shoot into these holes and close the door. This feature is owned by rack locks often like it, calling it automatic closing.

Variety of rack and pinion locks.

Rack locks were produced as industrial enterprises, and separately taken locksmiths at these enterprises. And thanks to this, there is just an endless variety of different types of rack and pinion locks. With forward and reverse movement of the deadbolts, with a round or rectangular key in section, made of brass or stainless steel.

All of them are united general principle work, which we described above, as well as the pros and cons, which we will discuss below. Regardless of whether a handy craftsman sawed down this lock, or not very much, at a factory - or in a school study of labors, from a good alloy or rusty iron.

Pros of rack locks

Of course, like everything else, rack and pinion locks have positive aspects. Let's try to list them.

Low cost. The uncomplicated design of the rack and pinion lock, the absence of a secrecy mechanism, and the associated low labor costs make rack and pinion locking devices frankly inexpensive.

In addition, a huge mass of rack and pinion locks made from unaccounted metal at enterprises were previously present on the markets. Locksmith Uncle Kolya wanted to have a drink on Friday night, took and made heels of locks at his work place at his turning-milling machine in half an hour. Then they found themselves in the market.

It is quite obvious that Uncle Kolya did not pay for the metal or for the depreciation of the equipment. Hence the low cost. And there are literally a million such examples.

Ask your loved ones who are over 50 years old. Each of them will definitely remember someone like Uncle Kolya, who made locks by pulling you, ten neighbors and peasants in the garage. The country was industrially developed, there were a huge number of locksmiths and technicians.

The second plus of rack and pinion locks is the simplicity and ease of use of the vast majority of them. There is nothing easier than poking a piece of iron into a single hole in a door, after which rack and pinion locks are usually opened.

And closing the door when exiting with such a lock is also relatively convenient. The key is not needed - with your fingers they held the bolt of such a lock inside the case, and the door was closed - the bolt would jump out and block the door on its own.

The third positive side is long term service. The overwhelming majority of rack and pinion locks are three huge iron rods and two springs, that's the whole structure. Therefore, they serve for 30-50 years, almost as long as the owner of this castle lives.

Cons of rack locks

And the first and most important disadvantage is low protective properties. The vast majority of rack and pinion locks are opened cleanly by a layman, without damage in a meager amount of time.

Interested - look on the Internet, opening with a carrot, opening with a string - a million examples. And it all works.

Do you understand, yes? That is, for a clean, silent opening of a rack and pinion lock, no special knowledge is needed, and a tool can be found for this underfoot. And the complexity of the key does not matter, as some people think. No matter how carved and huge the key is, the information on opening above will be fair for your rack and pinion lock.

In addition, we have already mentioned above that rack and pinion locks do not have a secrecy mechanism with their inherent serial secrecy. The master made in his life 100 locks from iron stolen from the factory, and all 100 locks have the same structure and keys. And if rack locks release some factory enterprise, he can throw locks with the same keys to the masses of thousands and tens of thousands.

That is, rack and pinion locks are in fact a fiction of locking. It seems to you that he is reliable and difficult for a thief, but in fact everything is exactly the opposite. Look on the Internet how to open a rack and pinion lock yourself with a string, a carrot and use it with pleasure! And beware of your neighbor-grandmothers - they can use the keys to their rack and pinion locks to open the rack lock on your door.

The problem of duplicate rack wrenches.

Making a duplicate rack wrenches requires separate equipment at the key point, the ability to process steel (in hypermarkets, because of the loud sound, for example, many do not risk doing this), as well as a number of specific blanks and skills.

In addition, rack and pinion locks were often made by locksmiths in piece copies. Therefore, they often bring such keys for which blanks do not exist stupidly.

Therefore, everything is very bad with duplicate rack wrenches. They are made extremely rarely where. And the cost of a duplicate is often equal to a quarter of the cost of a new normal lock.

If you want to replace the rack and pinion lock, you will face the third problem, this is the lack of analogues. No type of rack and pinion lock exists that would fit the same holes.

Therefore, if you suddenly wanted to replace a lock of this type, you will need to spend money not only on a new lock, but also on the services of an installation wizard. Fortunately, with such services now in cities everything is in order.

Breakage of rack locks

Nothing lasts forever, and even locking devices such as rack and pinion locks can reach the end of their life and break. We have encountered two major failures in these locks.

  • The first is the breakage of the spring that pushes the crossbar.
  • The second is heavy wear key and locking rails.

For example, in Nizhny Novgorod, you can contact the Door Doctor company, which has been providing these services for decades.

What to change rack locks for?

Replacing a rack and pinion lock on a metal door is a whole story. Don't expect to find another one for these holes - you won't find it at all.

And when choosing a lock in place of a rack and pinion, you need to adhere to several rules.

  1. The castle this time should have good security properties, relevant today. I see no reason to change the awl for soap and spend money at the same time.
  2. The lock should be easy to use, closed from the inside with a turntable, because the owners are used to it.
  3. The lock should have no end plate, because rack and pinion locks are often found on thin metal doors. And the end plate of the lock somewhat restricts its installation.

Based on this, when replacing rack locks, our craftsmen often install various types of Barrier locks. In the overwhelming majority of cases, one or another model of the Barrier is most suitable for the place of the rack and pinion and meets the high requirements of quality and safety.

Rack and pinion locks: how to open a rack and pinion lock without a key?

Rack locks are absolutely unpretentious, they work well both at minus and plus temperatures, they tolerate humidity and precipitation well, but due to their low burglary resistance, they are not recommended for installation in apartment doors.

However, for installation in a wicket or garage door, a rack-and-pinion lock is the best choice, especially if you combine it with a mortise safe lock.

Locks are installed overhead, on the outer surface of garage doors, fastened with screws or bolts.

There are legends about the service life of these mechanisms, they practically do not break, because springs and levers are completely absent in the design.

Methods for opening transom-type locks are quite primitive, universal and boil down to one thing: you need to move the slats one by one. Let's consider several ways:

  • Open the rack lock with a guitar string or fishing line .

First, we squeeze the door with a crowbar or a screwdriver, which we insert into the gap between the door and the jamb.

  • Open the rack lock with a carrot or pencil

First, grease or spill the WD-40 lock, then release the bolt by slightly pressing the door against opening and carefully drive a carrot or softwood pencil into the keyhole. Thanks to the soft material, the teeth of the bar will leave corresponding grooves on the carrots or wood and the lock will open.

  • Opening a rack and pinion lock with a screwdriver, awl or crochet hook

We press the door with our shoulder in the direction of opening and move one prong or notch at a time with a screwdriver, an awl or a hook along the crossbar. When the upper crossbar is open, we block it from closing with a match or whatever is at hand and go to the lower crossbar. Gently move under the parallel position of the upper crossbar and push the door.

It is possible to open a rack garage lock or a metal door with a drill without damaging the door leaf.
First, we push a sheet of paper between the closed door and the box, we determine the location of the closed crossbar. Then we drill small holes in the box and use a screwdriver (or two, depending on the lock model) to move the bolt.

Rack wrenches

Nowadays, it is quite problematic to find a workshop that makes duplicate rack and pinion wrenches. This is due to the fact that rack and pinion wrenches are rather difficult to perform due to a certain angle of cutting of the teeth and manual adjustment to the original. The crossbar key also belongs to the category of non-standard ones, it is rather difficult for it to find a blank.

The rack wrench is divided into two main types: with a round and a flat blank. In turn, the key blank has a thread on one or two sides.

A huge disadvantage of these keys is that they are very long and heavy, and the cost of a duplicate is quite high.

An overhead mechanical lock with several crossbars, received the name of a rack and pinion lock. The more crossbars, the more difficult it is to open such a device.

The lock works in a simple way. On the main transom, oblique grooves are cut at a specific angle. They match the angle of the key teeth. When the key is inserted into the keyhole of the lock, the teeth engage with the rail slots. When pressed, it starts to move and the door opens.

I must say that rack and pinion locks have a number of advantages. They work at any temperature, they are not afraid high humidity and precipitation. Therefore, this device is successfully used as a garage lock. But it is not difficult to open such a mechanism, therefore they are rarely installed in apartment doors.

Crossbar lock mechanism

This design is suitable for garage doors, especially when installed in conjunction with a mortise safe lock. Installation is carried out overhead, fixed with several bolts. Rack structures rarely break, since they do not have levers.

Where are rack and pinion mechanisms used?

Since this device does not react to the action of atmospheric factors, such designs have found application in various designs:

  • wickets;
  • garage door;
  • "Shells";
  • doors leading to utility rooms;
  • change houses,
  • sheds.

How the rack and pinion lock works

The whole structure consists of several parts:

  • frame;
  • key;
  • rail;
  • spring.

A rail is made from a metal rectangular blank. On it, bevel teeth and grooves are cut with a cutter while maintaining a certain angle. The number of rails can be different. To close the lock, a special spring is installed. The body is made of durable steel of various sizes and shapes.

The most difficult part of the lock is the key. When making it, you need to accurately cut the grooves, adjust them to the angle of the rail. Moreover, cutting can be carried out on both sides of the key.


Rack lock scheme

It is difficult to make a duplicate. Therefore, an autopsy, if suddenly there was a loss of a key from a rack and pinion lock, becomes a headache.

These keys are considered non-standard. It is difficult to find a suitable template to make a duplicate. The technology of work also causes difficulties. It is necessary to manually bring the teeth to match the rack. The shape of the deadbolt keys is varied. They are performed:

  • round;
  • flat;
  • long;
  • thick;
  • thin,
  • heavy.

Opening technique for rack and pinion models

How to open a rack and pinion lock without a key? What is the mechanics of this process? Some models are equipped with a device that allows the deadbolt to be set to the “locked” position.

However, even with a large number There are many ways of crossbars, to open the lock in case of loss of keys. All of them are used with one purpose - to move the rail and achieve its disengagement.

Let's get acquainted with the technology of how to open a rack and pinion lock with minimal cost... You need to take a strong thread or string. Use any tool such as a screwdriver to bend door leaf from the block. Insert the wire loop into the keyhole. It is pushed in to the length of the gap made. The loop should grip the rack tooth.

If you pull the put on wire, the rail goes to the side, the lock opens easily.


One way to open the rack and pinion

You can open the crossbar or rack lock with a sharp object. In the same way, create a gap, insert any sharp object... After it engages with the teeth, the rail is slowly moved until the lock opens.

If the lock has several crossbars, two or three approaches are performed. Each slid rail is secured with any suitable object. It must not move back under spring pressure. As soon as all the slats are shifted, it is enough to lightly press the door to open it.

If you find yourself inside the room, then you can open the rack and pinion lock:

  • key;
  • special handle.

Advantages

Rack devices are designed for long-term operation. They are unpretentious, trouble-free, never jam. Opening does not require much effort, even children can easily cope with them.

Today, such devices are no longer as popular as in previous years, so their cost is low and affordable for everyone.


Rack and pinion device

Negative qualities

The main disadvantage of rack and pinion locks is their low resistance to burglary. The above described techniques that are known to very many. For burglars, there is no problem how to open the crossbar lock. This is done with an ordinary penknife.

Modern security structures refuse to guard an object if the canvas is protected by only one rack and pinion lock. They find this device ineffective in properly protecting property.

Such rack and pinion models have custom sizes, differ in shape. If replacement is required, it is difficult to choose another lock due to the mismatch of the seat.

The technique of opening the bolt lock

The popularity of this device has long passed. Opening the crossbar mechanism is not difficult today. Of course, such a lock is not very reliable, but if you accidentally lost the key, then you know that you will be able to open it.

The easiest way is to open it with a screwdriver and a fishing line. A loop of fishing line is inserted into the keyhole. She needs to pick up the bolt that locks the door.

Using a screwdriver, the canvas is squeezed out so that the hooked deadbolt does not interfere with the opening of the door. In this way, the reverse acting lock can be opened.


Opening the latch mechanism

For the forward lock, opening requires other steps. For this, it is recommended to use a thin pencil. It must be inserted into the keyhole and pushed as far as possible. This item will play the role of a key and easily move the crossbar. If the pencil is made of hard wood, soak it in warm water.

If the fastening of the lock is made with bolts extending outward, then opening the door is simple: unscrew the bolts, remove the lock and enter the room. But no one does this, the lock is attached only from the inside, an exception may be the interior door.

When opening the lock in any way, remember that any crossbar lock is a fragile structure. Force can break him. If the bolt breaks, you will have to knock it out, buy a new lock and install it.

Actually open rack and pinion locking mechanism not difficult. All you need is the right tool. Make sure of the ease of the process by watching the video.
