How to change padlock. Selection and installation of an overhead lock on a wooden door. Necessary tools and materials
Overhead locks are such locks that, during installation, can only be attached to the surface of our door panels. The mechanisms of locks, which we used to call overhead, are of three types
- Cylinder
- Lever
- Pump (very rare)
How to choose the right padlock?
If you want to choose the right overhead lock, then it is important to fully study their classification according to the criteria that are the main ones.
Lock protection class
The first and, perhaps, practically the most important measure when comparing overhead locks may be which of the security classes it belongs to.
There are four main groups into which rim locks are usually divided according to their ability to protect your home.
Let's consider each of them separately in order to fully understand all the subtleties.
- The very first and most unreliable degree is the minimum. If intruders try to open such a lock, it will take them no more than five minutes to do everything and everything.
- The second degree of protection, otherwise called medium, will take about ten minutes to open a lock with this degree of protection.
- The third, or greatest degree - protection is supposed here when trying to drill out the bolt shank.
- Well, finally, the fourth degree, the so-called special. This includes locks for safes, which are selected individually. They have the fourth class of protection.
From this grouping of overhead locks, we can conclude that overhead locks with the second and third levels of protection are most applicable to the needs of ordinary citizens.
Castle design
The second measure of separating locks with an overhead mechanism into categories is the secrecy design used in them. According to this type, overhead locks are divided into a couple of groups - level and cylinder.
Level. They are used as an auxiliary lock. If such a lock is broken, then you have to completely change it
Cylinder. At the heart of them is a cylinder or, as you can say, a larva that unlocks the cylinder lock. The big benefit of using this lock, which distinguishes it from the use of a lever lock, is that when repairing this type of lock, only the larva changes, and the skeleton remains the same. 
Another measure of categorization of locks is the construction of secrecy or secrecy used.
Construction types
By type of construction, overhead locks differ as follows:
- lever locks - are used mostly as auxiliary locks. In case of any malfunction, such locks cannot be repaired. They only need to be replaced with a new one.
- cylinder - at the base lies a cylinder or, as it is otherwise called, a larva that unlocks the lock.
The big advantage of this lock over the one discussed above is that in the event of a breakdown, it is enough just to change the larva and no more problems. 
And quantity is a grouping factor by the number of crossbars.
Locks or, more simply, locks for overhead wooden doors are divided into a couple of groups according to the following criteria: they have or do not have crossbars:
- a lock with crossbars - such a lock has one to five of them;
- a lock that does not have crossbars - it works due to an electromagnet, with the help of which a metal plate on the door is attracted.
One of the criteria is to open the door from the inside or outside.
Locks are both one-sided and two-sided. Here the choice is up to you. Let's take a look at one-way and two-way locks in more detail to get an idea of the difference between them.
- locks are called one-sided, which can open only on one side, and a handle will be attached to the other, and when it is turned, our door will open. It's called turning.
- simplex, in other words, bilateral locks, these are locks in which the opening process is carried out only with a key, both from the side of the apartment and from the street side.
Functionality
According to this principle, several such groups can be distinguished:
- spring latch at the lock - such a lock is opened either from the inside with a door handle, or from the street side with a key. In this case, the latch can be wound into the case or it can be closed with the help of a button located on the case, which should be pressed;
- the fixed latch of the lock, which can be said to be additional or auxiliary, has a triangular shape and fully automatically secures the deadbolt of this lock at the time when the door is locked. The handle is secured with a key, and the latch retracts back into the body with the push of a button.
These measures are the main ones, and they should be used when choosing a lock that can provide really very good protection.
Installing padlock
The process for installing our lock is as follows:
- Using a ruler, you need to measure and mark one third of the height from the top of the door. This is done on both sides of the door. In the marked place, we drill a through hole.
- We need to drill a hole for the cylinder. We carry out this work with a drill, which is called a chisel, and note that the hole must match the diameter of the cylinder.
- In the hole that we drilled in our door, we need to place the finger bracket and, of course, the cylinder from the front side, after that we need to return the plate that is the installation plate to its rightful place. Now, having carefully examined the field of our activity, we see that one of the parts remained protruding from the connecting rod. We need to cut it. You can do this with a hacksaw.
- Well, now both the cylinder and the finger brace can be inserted into place. Next, the plate, which is the installation, should be evenly put on a special part of the rod. The one that remained uncircumcised. And then we need to use the long screws that are in the configuration of our lock to attach it to the cylinder.
- Next, we press the button on our lock and this gives freedom to the valve, due to this, our lock has the opportunity to stand in place, that is, on the plate. The rod cut off by us is simply obliged to fall into the slot, which is located on the skeleton of our castle. Then we take the smallest screws and attach the skeleton to the plate.
- With the button we move the valve so that our lock is locked, we cover the door and the upper and lower parts of the place where the tongue will subsequently go.
- With the help of a chisel and a hammer, we make a hole where the marks have just been drawn.
- In the place that has just been hollowed out, we will place a plate, close the doors and check whether our lock closes correctly.
- If it is correct, then we fix everything and use the new lock with joy.
People who own a country or country house have to do various things on their own - whether it is installing door locks or. Everyone knows that maintaining a house in a village is troublesome and costly. But, nevertheless, every year more and more people buy housing outside the city, as the pleasure of relaxing in the countryside outweighs all the inconveniences associated with it.
What is the singing of birds, fresh air, the fragrant smell of freshly cut grass before the fact that the water is in the well, and the bathroom is outside? Nothing. Moreover, over time, you can equip everything and make housing comfortable. After all, there is now plenty of information about suburban construction, if you want - buy a book, if you want - look on the Internet. For example, after reading this article, you can learn how to install a door lock with your own hands.
On, in addition to the house, there are usually many different buildings. And almost everyone has doors. To protect the house and buildings from uninvited guests, especially if you visit the dacha on short visits, you need to install a door lock on each door. You can, of course, call the master, or you can save a decent amount and please yourself with a delicious treat. Here, for example, is excellent. Moreover, installing door locks with your own hands is a simple matter, accessible even to a novice summer resident. Today we will tell you how to install mortise and overhead locks in wooden doors.
INSTALLATION OF THE MORTISE DOOR LOCK
From the tools we need a drill, a pen for drilling, a Phillips screwdriver. We will install a mortise door lock with a regular width of 5 cm. We will open the package with the lock - in addition to the lock, keys, locking plate, decorative overlays and screws, there may be a template in it.
We choose a place on the door where we will install the lock. Usually this distance is 1 meter from the floor. Try to visually determine the height so that it is convenient for you to open the door with a key. Go to the door, lower your hand down and touch it, add 15 cm upwards to this point - this will be the place to install the door lock.
We measure the width of the lock to be inserted, select the pen for drilling 2 mm wider than this size.
Now you need in the door leaf for the key. Let's do it with the same pen. Before that, let's take the size from the lock and transfer it to the door to determine the place where the key will be inserted. Remove light roughness with a file. Let's make sure that the key is easily inserted into the lock. After that, we will check the lock for operability, it should open and close without any effort. If everything suits us, we fasten decorative metal plates on both sides with screws, if not, we look for the cause and eliminate it. It remains to fix the lock in the door by tightening two self-tapping screws.
At the end, we will install a locking plate in the jamb. To do this, close the door, open the lock with the key so that the bolt rests against the door frame, mark with a pencil the place of their contact. Take a plate, circle it around the perimeter. With a chisel, we will select excess wood so that when the lock is closed, the bolt goes into the jamb to the full depth and so that the locking plate is flush with the jamb. We fix it on 1 screw and check the operation of the lock. We close it by 2 turns, while nothing should interfere with the bolt of the lock. Now we fix the plate with another screw.
RIM LOCK INSTALLATION
A rim lock is even easier to insert than a mortise lock.
We attach the lock to the canvas and fasten it with four screws.
INCREASING THE SAFETY OF THE COUNTRY HOUSE
Country houses are closed not only with mortise or overhead locks with numerous secrets, ordinary padlocks are still common in rural areas. They are hung on locks, consisting of two parts: one part is fixed on the door, and the second on the jamb. Basically, rural residents fix constipation carelessly: they are attached either to screws or nails. The second part of the constipation, which is attached to the jamb, is popularly called a test (according to Ushakov's explanatory dictionary, this is a metal shackle for hanging a lock), they are generally made from a nail: they bend it in the form of a bracket and hammer it into the jamb with a hammer.
In fact, the size of the castle in this case does not play any role. To get into the house - you don’t need to break it, just unscrew the screws or pull out the breakdown.
We will take out a sample from a bent nail from the jamb and hand it over to the metal collection point. Instead, we will install a constipation bought in a store. We drill holes in it for the diameter of the bolt, drill through the jamb and insert the bolts. On the back of the jamb, put washers on them and tighten the nuts.
To date, the market offers various types of overhead locks, ranging from the simplest latch to overhead cylinder.
In the event that the cylinder mechanism crashes into the door leaf, then such an invoice will be no less reliable than a high-quality mortise one. The quality of the invoice directly depends on the number of pins. If there are at least five in them, then such a lock will rightfully be considered reliable. In addition, all invoices have a stopper and a fixing shutter.
The reliability of fastening the lock to the door frame directly determines its quality. During installation, the lock and its latch are located on the door leaf. In order to increase reliability, the screws with which it is attached must be chosen longer than those that come with the kit, while the diameter of the fasteners must be identical to the standard ones.
Almost all cylinder rim locks are suitable for doors of various sizes. Before installing a padlock, you should check the quality and strength of the door. Otherwise, it can be knocked out.
At the initial stage of installation of the overhead lock, you need to determine its location. If the lock is supplied with instructions, you should use it. As for the height, one third of the height of the door, starting from the bottom, is considered the most optimal. The marked place must be drilled with a chisel-shaped drill. It should be the same diameter as the cylinder. This step must be taken with care so as not to damage the door.
Having received a hole, it is necessary to insert a cylinder and a ring from the front side, which will fix it. Then you need to measure the desired length of the rod. The optimal protrusion outside the interior doors is 12 mm on each side. Excess must be cut off with a hacksaw. Then you need to put a mounting plate on the cylinder and fix it on the surface of the door. The front edge of the plate must be flush with the edge of the door.
At the next stage, you need to fix the lock itself on the plate by pulling out the rod. On the rod you need to put on the back side of the lock, thereby determining its location. At this point, you need to secure it tightly with long screws.
Having determined the position of the locking body using a chisel, it is necessary to cut a groove according to these dimensions. Its depth is determined by the thickness of the locking plate. Then you should firmly fix it.
It must be remembered that the reliability of such a lock is primarily determined by the quality of its installation. Interior doors are usually not equipped with locks, but if necessary, a lock can be installed on them. Basically, internal locks are inserted into the door, they are less visible and they look more aesthetically pleasing. The choice is yours!

The method of installing a padlock depends on the object on which the installation is carried out. Most often we are talking about wooden and metal doors or gates, gates or gratings that protect equipment from unauthorized access. Quite often, padlocks are used for closing with a steel chain, this technique does not require the installation of lugs: it is enough to wrap the chain around metal bars or a picket fence and the door is locked.
Installing a padlock on wooden doors
To install a padlock on wooden doors, you will need the following tools and equipment:
Eyelets, which are often supplied with the lock;
Chisel and hammer;
Screwdriver or screwdriver;
Self-tapping screws or screws from the lock kit.
A place is chosen for installing the lock, the height should be convenient for opening by everyone who has access to this door. Marking is made on the door jamb and the side of the door leaf. To do this, each eye is circled with a simple pencil, they should be parallel to each other.
After marking, it is necessary to use a chisel and a hammer to select the door jamb and the canvas to a depth equal to the thickness of the lug. You can overdo it in this case, this will reduce the risk that the brackets will touch each other when opening the door, but not by much, since the selected part will not look very attractive.
After the platform is selected along the eye, it remains to fasten it with self-tapping screws or screws through the factory holes. If the wood is hard, then you must first drill shallow holes with a thin drill. After installing the eyes, it remains only to hang the lock.
Installing a padlock on steel doors or gates
To install a padlock on metal gates, the welding method is most often used, so the eyes are chosen from a rather thick metal.
They are not included in the kit, so it is best to go to the market for them. Unlike wooden doors, the eyelets are not chosen flat, which are flush, but angular. The platform serves to ensure that the bracket can be conveniently welded on top of the door, since it is long and economically impractical to select or drill metal for a flat eye. Eyelets are installed so that they do not interfere with each other when opening gates or doors and are welded using a welding machine.
What to do if there is no welding machine
In the absence of a welding machine, you can install the eyes using a bolted connection. To do this, it is necessary to choose brackets with a field of long and wide areas, the size of which will allow three to four bolts to be placed at a distance of 2-3 centimeters from each other. For work you will need:
Bolts M8 and M12, length convenient for mounting;
Electric drill with drills for metal with a diameter of 8-12 mm and 2-3 mm;
Two wrenches.
First, markings are made on the eyelet site, holes are drilled in the designated places with a thin drill, which are expanded with a thicker drill. After that, the bracket is applied to the door and the locations are marked with a bolt. They are also first drilled with a thin drill, then a drill corresponding to the diameter of the bolt is used. Having finished drilling, proceed to screwing the eyes with bolts, for which two wrenches are used. A similar operation is carried out with the second eye, after which the door lock is hung.
There are a huge number of forms and models of overhead locks - from the simplest heck to the cylindrical mechanism. With the correct installation of the overhead lock on the door leaf, it is not inferior in reliability to the mortise.
The reliability of a padlock directly depends on the number of pins used. The most reliable models are designs with five or more pins, a high-quality stopper for fixing the locking mechanism in night mode. In addition, a high-quality installation depends on the method of mounting the fasteners to the door leaf and frame. Overhead locks, together with the valve, are installed on the canvas and fastened with screeds or self-tapping screws. You should not use the self-tapping screws that come with the kit, it is better to purchase longer ones with the same diameter.
Standard rim locks with a cylinder system are equally well suited for all types of doors: metal and wood. Before installing the overhead lock, you must make sure that the canvas is strong, otherwise the door can be knocked out without much effort.
How to install a padlock?
If the door is a standard size, mark one third of the length from its top. Sometimes a template for marking the central part of the device is not attached to the lock kit, therefore:
- reading the instructions for installing a patch lock, using a square, we make markings, and at the obtained point, use a drill to drill a hole.
- independently, on a sheet of paper we draw the contours of the lock, mark the holes for the fasteners and the keyhole - we make a template
After that, with a drill (for wood or metal), the diameter of which must correspond to the dimensions of the cylinder expands the seat for the cylinder in the door leaf. The hole is drilled on the mark on both sides of the door leaf, which will avoid chips on the front. We insert the cylinder of the padlock into the hole made and fix the case with the fixing screws. On the outer side of the door, we install an overlay on the key hole.
Next, the overhead lock is transferred to the closed state, after which the door is pressed against the box and the installation location of the locking body is marked by marking the upper and lower parts of the crossbar. In accordance with the markup, the body of the striker holder is installed and outlined with a pencil.
With a chisel or drill, a recess is made according to the marking, so that the rim of the valve holder plate is flush with the surface of the door frame. The body is inserted into the recess made and holes are made.
Very similar to installing locks in wood, the only significant difference is the tools! At the final stage, the door leaf is closed and it is checked how tightly the locking mechanism of the overhead lock fits into the body of the valve holder. If everything coincided, then fastening is made and the quality of work is checked.
Need to replace a padlock with a different model? Suitable model with a cylinder mechanism! As an alternative or analogue of a rack lock for entrance, metal or wooden doors, you can install a surface-mounted cylinder-type lock. The photo shows one of the options.
A slight alteration of the door leaf will be required, but installing an overhead lock of a cylinder model instead of a rack model will block the old mounting holes. As a nice bonus, you will change the bulky rack and pinion wrench for a neat, flat, small one.
