Various locking mechanisms are presented on the market in a large assortment, so it’s not so easy without having necessary information, choose suitable option. Let's consider a group such as locks with a remote keypad for dialing a digital code. If you want to install at home similar device, you should find out more about the principle of operation and technical characteristics different models.
Professionals classify locking mechanisms with a code according to 2 main criteria: type of device, method of control.
Type locking device with a code is determined by the method of its installation. It could be:
- mounted;
- mortise
According to the principle of operation, models with code are divided into:
- mechanical;
- electronic.
Mechanical combination door locks are not as reliable. They fail much faster than electronic ones. In addition, you can easily select a key for this lock mechanism. The main advantage of locks with such a system is their simplicity of design. There is no need to connect power to them. Such devices are resistant to sudden temperature changes, high humidity and dampness.
Among the main advantages electromechanical models opportunity should be highlighted remote control device. If you install such a lock on a gate or front door, you can let guests in with a simple press of a button. It is advisable to install electromechanical devices on the front door in conjunction with an intercom. Another plus of this model is its versatility. You can install a lock on plastic door, gates made of corrugated sheets or .
Cons combination locks more than advantages, but they are all fixable:
- Dependence electrical supply. This problem only affects magnetic devices. They cannot be opened if the electricity is turned off. The remaining locks are opened manually from the inside.
- Exposure climatic conditions. The device may become frozen or rusty. To protect the mechanism, special pads should be used.
In the event of any breakdown, the door may become locked from the inside, so it is important to service the device annually.
Application area
Mounted models are used to protect against outside intrusion outbuildings, garages or storage facilities. It is more appropriate to place on the front door of a private house or apartment mortise device. There are also overhead locks with a code. Mortise models are mounted inside the door leaf, and overhead models are installed on its surface with inside.
Locking mechanisms with a push-button code panel are installed in the following buildings:
- entrances apartment buildings;
- offices;
- production premises;
- public buildings;
- laboratories;
- on gates and wickets.
All these places are highly trafficked. The door is frequently opened and closed, and a combination locking device makes access as convenient as possible.
Principle of operation
Mechanical door locking devices operate on a simple principle. After dialing required quantity numbers, the bolts are set in motion, unlocking the shut-off valve. A reciprocating spring is provided to lock the lock. She returns locking latch to the starting position.
The device for entering the code can be presented in 2 versions:
- pressure cylinders;
- swivel discs.
With frequent use, the buttons on the device become worn out, thereby indicating the code numbers. Using the most worn-out buttons, attackers can easily find the right combination, so the button panel must be changed periodically. The safest is the second option. The more swivel wheels there are on the lock, the higher its security. It is impossible to open a padlock with rotary discs without knowing the code.
IN electromechanical devices the bolt, which is cocked, fixes all the mechanisms. The door is closed. After entering the code, voltage is applied, the latches are reset, the bolt goes under the door body, and it begins to open.
Electronic codes have enough complex design. They can be equipped with a rotating mechanism or a touch digital panel. Such a reliable model should be preferred if you are choosing a lock for a safe or for a secret object with limited access. This device is also suitable for interior door, but it's not cheap. If you are limited in cash, you can look for other options.
Aspects of selecting a reliable model
If you decide to install a lock with a code, you need to choose it responsibly. pay attention to the following factors:
- Degree of reliability. If you need to provide reliable protection, buy an attached electronic or electromechanical product.
- Price. Purchase mechanical device will not cause significant damage to your family budget. Products on electrical basis are more expensive. The most profitable and reliable option— electromechanical system.
- Degree of secrecy. Increased level protection will be provided by an electromagnetic door combination lock which opens additional element— card or keychain. You can also use a remote control to send the code. Recently, models have appeared in which you can use it as a spare key. mobile phone. In this case, the owner can restrict access to the premises, even if the right combination.
- Material from which it is made door leaf. For metal door you need to choose a model with durable crossbars.
Experts recommend using several protection systems in combination. In this case, attackers will not be able to break into the door under any circumstances. The most important thing is not to disclose the code to strangers. An electronic combination lock for the front door is the most reliable security option, but it is not suitable for intensive use.
Door installation
Installing combination locks is a responsible process that is best left to specialists. But if you have necessary tool and know how to use it, you can do this work yourself. To install the device on an armored door you will need:
- drill;
- screwdriver;
- screwdrivers;
- roulette;
- marker.
The device comes with operating and installation instructions. Each model is attached differently. After reading the instructions, you can easily install the locking device yourself. Installation procedure:
- Mark the place where you plan to mount the mechanism, and also determine the area for installing the keypad (if the device is electronic).
- Use a marker to mark the fasteners. Some manufacturers include a special stencil for the lock. It is glued to the canvas and markings are applied.
- Use a drill to drill holes for the screws. If you purchased a mortise model, a niche the right size done using a grinder.
- The last stage of installing the locking device is fastening decorative panel on the buttons. TO electronic device a power cable is supplied, which supplies a voltage of 20 V through the connecting wires.
After installation, you need to check the operation of the device. Open the door and open and close the lock several times. If there are no problems, close the door and repeat the procedure. The lock was originally installed secret code. It is indicated in the instructions. To ensure reliable protection, it is necessary to change code combination. Installation on wooden doors is carried out according to the same principle.
How to set up a combination lock?
To understand how to set up a lock with a code, you must carefully read the instructions, which outline the manufacturer's recommendations. The device must be recoded to following cases:
- change of factory code;
- for security purposes if the code is found out by unauthorized persons.
Experts advise changing the code at least once a month. Thanks to this, you will ensure your own safety and the safety of your property. You can reconfigure mechanical locks yourself, without the help of professionals. For this you will need special device, which is inserted into the hole on the code panel. It is designed to change the location of the lock cylinders and, accordingly, the lock code.
When changing the code, you must open the door wide so that the bolts are extended all the way. Turn the device through the hole to the maximum, insert another key and close the bolts back. If the lock responds to the updated code, you have done everything correctly. To set up electronic models you will need special devices that are used by professionals.
Code door lock can be a good alternative to heavy bunches of keys rattling in your pockets. Moreover, keys tend to get lost, and the code is not that difficult to remember.
Such locks are designed to prevent burglary and unwanted intrusion into your property.
Find a code combination or break a combination lock in a relatively a short time is almost impossible, and this allows it to increase the security of your home many times over.
Mechanical and electronic combination locks
Currently, there is a wide selection of mechanical and electronic combination locks of domestic and foreign production. The installation of one or another type of combination lock on the door is motivated by the purpose of the protected premises.A mechanical combination door lock is more suitable for rooms that are used many times a day. For example, the entrance to a residential building.
An electronic combination lock is more reliable, but is limited by the number of times it is used during the day. This lock is intended for a private home.
Locks vary in degree of complexity, but are also labor-intensive to maintain. Latest designs electronic locks, the code on which can be changed as often as desired, are perfect for protecting sensitive objects.
Mechanical combination locks and their advantages
Mechanical products, in which the lock itself must be removed to change the code, will find application in garages, industrial, warehouse and vestibule areas. You don't have to make a key separately for each employee or client; the code will be the same for everyone.
Also to the benefits mechanical locks Let us note that they do not require power supply and are much cheaper than electronic ones.
Installing and repairing a mechanical door lock will also cost less because the process itself is less labor intensive and the components are less expensive. Without being overly complicated, the mechanism of such a lock is less susceptible to breakdowns and physical damage from the outside. The only threat is to freeze if the temperature is too low in winter.
Additionally, by connecting any of the locks to the alarm system, we can further increase the level of security of the protected premises or territory.
Code locks Mortise and overhead types are produced. For installation, the door thickness must meet certain standards - 30-60mm.
To install a combination door lock, it is better to contact specialists, but with the proper skills, you can install a mechanical combination door lock yourself.
Algorithm for installing a mechanical combination lock on the front door:
- Choose the right type combination lock for a specific door;
- We outline where the main mechanism, the response part and the code panel will be located;
- Using a drill, we make four holes for the main part of our combination lock;
- We attach code panel, having previously made the necessary holes;
- We insert the connecting element into the locking mechanism of our combination lock, and also fix the main block on the door leaf;
- We install the counter part on the side surface of the box;
- We check whether our lock is functioning.
Digital or combination locks are mechanisms that are opened not with a key, but by dialing a certain numerical combination. Either in a certain sequence, or by simultaneously pressing the buttons. It depends on the type of castle.
Let's take a closer look at what types and designs the industry now offers and choose the best combination lock.
It is believed that the operation of a combination lock was first described in the early 13th century by the eminent Arab scholar Al-Jazari. By the way, he was the first to invent programmable robots.
In the mid-19th century, the enterprising American James Sargent patented a mechanical combination lock with replaceable codes. The design of Sargent's castle is still popular today due to its:
- reliability;
- relative cheapness;
- practicality;
- versatility.
In simple mechanical ones, opening occurs by arranging pins or cylinders in a given sequence; in electronic ones, by typing a code on a digital keypad or keyboard. In advanced models voice dialing possible.
In electronic locks, the memory of the code is stored on a special memory.
Electromechanical ones have both types of keys: mechanical and electronic.
Scope of application of combination locks
Combination locks found wide application in many areas:
- for the protection of private property (installation on gates in private houses);
- for the protection of warehouse and utility premises;
- for protecting the entrances of apartment buildings;
- for security of office premises.
Code locks are installed Firstly in safes. However, they use both types of combination locks (mechanical and electronic), often “in pairs”.
Mechanical combination lock suitable for installation on doors in passage rooms. For example, in “crowded” offices or in apartment buildings. It's convenient and practical. The absence of keys reduces the cost of installing the structure. Employees and residents just have to “hand out” the door code. The room “protected” by a combination lock will be completely safe.
Suitcases, briefcases and bicycle locks also use combination locks. They are easy to use and not expensive.
Types of locks and their advantages and disadvantages
Mechanical combination locks are divided depending on the installation method into:
- mortise;
- mounted;
- invoices.
The first type of lock mechanisms cut into the door leaf. Such designs are suitable for doors made of wood or iron, with a door leaf thickness of 30-60 millimeters. The “hidden” design of such locks protects the locks from moisture and cold. They are suitable for installation on . Significant disadvantage mortise models- relative complexity of their installation.
Overhead locks are installed on the surface of the door. The advantage of this type of design is ease of installation and preservation of the relative integrity of the door leaf. Disadvantage - openness to aggressive external influence atmospheric precipitation and dust.
Mounted models are used on bicycles, barns, boxes, suitcases. Plus - ease of use, low cost. The downside is not reliability. Amenable to “professional” hacking in 10-15 minutes.
Pros and cons of designs
The internal design of a combination lock is:
- cylinder, with indirect drive of the bolt rod;
- lever, with direct drive of the bolt-rod.
According to the coding method, there are three main types of mechanical lock designs:
Block 50% from the beginning of the article
- with two or more set circles;
- with one dial;
- with pins.
A lock with a single dial is not reliable, since it has a limited set of combinations. There are 1000 of them. An experienced and even inexperienced “burglar” will select a combination in 20-25 minutes. Such designs are used more often for cases and bicycles.
A lock with several dials cannot be cracked in 5 minutes. It is designed in such a way that under the first dial there are also dial circles parallel to it. When selected correct position for the first disc, you can hear a very weak characteristic click. Not everyone can feel it.
Pin lock is easy to use, but not secure. The sequence of numbers in the code does not matter. There is no significant difference - dial “123” or “231”, the lock will still open.
Aspects of selecting a reliable model
The choice of a reliable model depends on the following parameters:
- degree of protection;
- financial opportunities;
- operating conditions (outdoors or indoors).
According to the level of protection, locks are divided into 4 security classes depending on:
- resistance to bolt impacts;
- resistance of the lock to the method of breaking and destruction;
- resistance of the lock to strikes from the strike plate;
- resistance to burglary without destruction.
The main criterion for classifying a model into a particular security class is the time during which a specialist manages to open it.
Review of popular manufacturers
Particularly popular on Russian market two companies: Italian Cisa and Mattam. The main advantages of locks from these companies:
- resistance to unauthorized decryption of the code;
- long service life;
- impact resistance and wear resistance;
- maintainability.
Model "Mattam ZKP -1"
- installed on a door leaf with a thickness of 24-35 millimeters;
- has steel lock parts and nickel plated;
- contains a set of 1000 possible combinations codes and 10 buttons that can be recoded.
Model "Cisa Basic"
This castle has great amount crossbars, the ability to connect a vertical drive and a mechanism recoding function.

What to do if you forgot the code
The problem does not occur very rarely. It is common for push-button locks to lose paint from or around commonly used buttons over extended periods of use. Over time, the code becomes visible to the naked eye. Also, frequent pressing of the same buttons leads over time to their “sticking”. In this case, the code is selected using the “scientific poke” method, when all the buttons are pressed in a row, and the “necessary” ones “stick” a little.
Code padlocks selected by rotating the roller while simultaneously “unlocking” the pin. When the roller that is closest to the pin turns, you feel the moment when it “falls” into the groove. The remaining rollers are “unlocked” in the same way.
If it is assumed that the lock will be installed outdoors, then close attention must be paid to the design of the tightness of the lock body. If moisture gets inside at sub-zero temperatures, the lock will stop working.
When choosing a lock, experts advise paying attention to how and what the lock is assembled from:
- body - without cracks and slits;
- the latch mechanism works without distortion;
- Key material does not wear out;
- steel parts;
- the coating is nickel-plated or coated with other anti-corrosion material.
And besides, you must be aware that a combination lock in the hands of a criminal “specialist” can be opened quite quickly. This especially applies to simple disk locks, which are used when parking bicycles and the like. We present to your attention a video where the process of opening such a lock is demonstrated very clearly.

To protect their property, owners of houses and apartments use many locks on their doors. They are distinctive not only in their technical specifications, level of protection, but also in its dimensions. It is not uncommon to see 3-4 locks on a door. Code door locks can replace this a large number of door shutters. They have many features that combine all the locks on one front door.
Design and dimensions of an electronic combination lock
The combination lock is distinguished by its opening. To do this, you don’t need to look for a key, you just need to press a combination of buttons in a certain sequence or press several specific buttons at the same time.
Door combination locks are used in various places with one purpose - protecting property from looters, robbers and thieves.
Places of application:
Various areas of application for locks of this type have made it the most common. It has many advantages and virtually no disadvantages.
Advantages and features of a combination lock
The advantages of a lock with a code can be listed for a long time, remembering even the smallest detail that can affect the comfort when opening the door. It is worth noting the main differences from conventional locks of varying complexity and degrees of protection:
Types of locks with a code on the door and their features
With a combination of 6 numbers on a combination lock, there are 100 million opening options. This eliminates the possibility of selecting the desired code.
Home distinctive feature Installation of the lock control unit is considered. The block is installed anywhere away from the lock itself. This makes the locking device “invisible”.
The thief is perplexed, how is the door closed? How to get inside? And if the alarm is connected, then within 2-5 minutes, security will come to the curious robber. 
The lock mechanism has a processor that stores combinations of numbers. There may be more than a million such options. A person will physically not be able to cope with the selection of the code to the lock. The electronic combination lock is divided into subtypes:
Some disadvantages of combination door locks
The technological process constantly introduces updates to electronic mechanisms. Combination locks are no exception. If a deficiency is identified electronic lock, this disadvantage is eliminated and a new combination lock is produced. Therefore, after a certain period, the lock needs to be changed (updated).
An example of an electric lock embedded in a door
The second disadvantage is the installation of a lock on the door. The owner will not install a combination lock with his own hands. You need to call a specialist who will do correct installation electric lock, connecting and setting up the lock.
Types of combination locks
Combination locks differ in the type of installation and the type of opening.
By type of installation - padlock combination lock, mortise lock, hidden locking mechanism. The padlock has the simplest coding device mechanical lock, used most often at entrances, in kindergartens, schools, entrances to parking areas, and other places.
The simplest combination padlock
Mortise locks are installed by cutting the mechanism into the door. These locks also have a simple mechanism and are mainly used at the entrance to elite territory. Basically, such a castle is controlled through a guard. 
According to the type of opening of the door combination lock, there is a difference in the types of mechanisms used: mechanical lock, electronic type. The latter option is applicable on the doors of houses, offices, and luxury apartments, because it has a complex design.
A mechanical lock often becomes unusable (when the buttons become stuck) or when the roller teeth are eaten away. Another option for a lock to break is that pressing the buttons incorrectly blocks the entire lock. In this case, a specialist is required.
