Combination mechanical lock - for the front door and gate, price and instructions for the lock

A combination lock is a mechanism that ensures the reliability and safety of a home or things that need to be left unattended for a certain time. They are installed on the doors of apartments, office rooms, entrances, safes, and bicycles.

The editors of the YaNashla website have prepared for your attention a rating of high-quality combination locks from the best manufacturers. Let's look at their types and recommend the best models.

Advantages and disadvantages

A mechanical locking device, like a regular lock in principle, is designed to protect a residential area; the code model does not have a keyhole, which means it is unlikely to be possible to open the door with a master key.

In addition, the design of the lock is different:

Durability.
Reliably, the door can be opened and closed only by dialing a code known only to the owner of the home.
Resistant to sudden temperature changes.
Lack of sensitivity to moisture, dampness.
No keys, which is quite convenient.
Resistant to mechanical burglary, no keyhole.

According to the modification, the lock can be overhead or mortise, and in design it can have a lever or cylinder shape.

Locking method:

With a dial, a characteristic click is heard when the door is opened, such locks are suitable for safes.
For storing valuables and secret documents.
With several turntables, placed on suitcases, bicycle ropes. But the lock is three-digit, so logically, to open it, it is enough to go through no more than 1000 combinations; to open it, a burglar only needs 15-20 minutes.

Digital locks are also available. In addition to all the advantages described above, they have a big drawback: if the keys wear out over time, the cracker won’t even need to select the numbers; the code will simply become obvious to him from the worn numbers.

Rating of the best devices for bicycles

A bicycle locking device ensures its safety while parking. Coded anti-theft agents are considered the best.

Bicycle Code Standers, 14 mm, 160 cm

Advantages:

reliable;
easy;
cheap;
high functionality.

Flaws:

none.

Principle of operation

The mechanical device is triggered when the door slams, the return spring is charged, the start head is in the bar, and the latch is moved. At the moment the code is pressed, the buttons move the required plates, acting on the lock cage, thereby releasing it. The return spring attracts the lock head to itself; when the button is released, the latch and spring return to their original position.

The electromechanical device is distinguished by a cocked bolt that secures all mechanisms, while the door remains closed. When voltage is applied, the clamps are released, the springs move the bolt under the body, and the doors begin to open.

Mechanism design

Despite all the external manufacturability, the coded models of locks are quite simple. Their design is formed by a set of mechanical components, which, in turn, are activated by electronics. A latch, a spring, a cage with a lever and a set of pins are the technical basis that forms a mechanical combination lock. The device also includes a high-strength shell in the form of a housing made of steel alloys. Although there are also combined solutions for the metal formation of cases of non-standard models.

In this case, it is necessary to distinguish between directly electronic and mechanical devices. The difference is that fully electronic modifications store code combinations in the locking system controller. Mechanical combination locks, on the other hand, store the correct code sequence in the form of a specific arrangement of the aforementioned pins and rings. When you press the button, the shift is activated, and the corresponding latch releases the lock cage.

Kinds

By type, the device can be mechanical, electromechanical and electronic:

A mechanical combination lock does not have a keyhole, it is impossible to open it with a master key, but the big drawback is that if you forget the code, you will not open the lock yourself, which will bring additional trouble. The mechanical model is more suitable for gates that automatically latch when the door is closed. From the outside, to open it, you just need to enter the correct set of numbers.
An electromechanical lock contains mechanical wires and requires an electrical supply to operate the device. Such locks are more reliable, larger in size, and can be installed on powerful gates of office and warehouse premises. But, it is difficult to install such models and they are expensive. The device includes both mechanical and electronic elements, it is mounted in a surface-mounted or mortise manner, the design includes a cylinder mechanism; if the electricity is turned off, the lock can be opened with a regular key.
The electronic device contains a programmed electronic unit. When you install the program, that is, a certain combination of numbers, the lock will open easily. Depending on the location and method of installation, it can be a hinged, mortise-mounted one. A cheap hinged one can be easily removed, but is unattractive in appearance, not aesthetically pleasing, and can be quickly hacked or cut down. The invoice has a higher level of security; the case is equipped with a special button, by pressing which you can easily open the door. Mortise models are the most reliable, but installation is labor-intensive and requires certain knowledge.

How to choose

When choosing, pay attention to the appearance of the device, the availability of components, warranty card, and instruction manual. Important parameters when choosing: degree of protection and installation location, outdoors or indoors.

Mechanical models are simple, inexpensive, but have few degrees of protection. Electronic models are equipped with an excellent design, more advanced, beautiful in appearance, equipped with a button or keys, which is convenient and fashionable. When arranging a gate, it is better to choose a digital model; there are many combinations, the number of inputs is limited, and it is difficult to hack such a device. A mechanical lock on a metal base is suitable for the entrance, which is also convenient and practical.

Application

Products in this category are intended for use at large facilities: multi-storey buildings, industrial enterprises, administrative buildings. Considering the number of people who use shared doors, using a code instead of a key is the most efficient and secure option.

Security mechanisms are used for exterior and interior doors. Combination mechanical locks are often preferred by owners of personal safes, metal cabinets, and other steel structures with door leaves.

When purchasing, you must make sure that the selected product meets the requirements in which it will work. This compliance must be in the form of a written document bearing the logo and seal of the manufacturing company.

The best manufacturers

The scope of application of locks is growing every year, so manufacturers today are also different. Russian locks Sirius and Metteham, and Masterlock made in China have earned more trust.

Models differ in price and functional characteristics. To install an inexpensive, reliable lock on your gate, it is better to take advantage of the offer from Mattem. The design is simple, easy to use, and with a thickness of 50 mm, it can be installed on almost any door. There is a code panel that supports about 1000 combinations, the numbers are arranged horizontally in 2 rows. The manufacturer is domestic, so the device can be trusted, and it is inexpensive - 1100 rubles.

If you need to purchase a more advanced device with additional functions, pay attention to the Sirius company; more expensive models cost up to 35,000 rubles. but the models have a creative design, rich chrome-plated or gold-plated body trim. Suitable for any door, built-in fuse for reliability.

Chinese manufacturers offer different models. Experts recommend Masterlock; its design is similar to a central mechanism consisting of shaped code plates with cutouts for moving the bolt bolt. The greater the number of plates, the more variations of the code; in the device from Masterlook there are more than 2.5 million of them, it is impossible to open the lock.

Characteristics

Mechanical code locks are a solution for metal or wooden entrance doors, gates, garages, and outbuildings.
According to the principle of operation, devices of this series are unlocked from the street, for example, by simultaneously pressing buttons or in another way, according to the design of a particular model. To open the door from inside the room, just press the handle. The mechanisms are often equipped with an adjustable latch system, which makes it possible to install them on the right or left door. Manufacturers include instructions with the product that allow home craftsmen to independently understand the operation of the device and its installation.

Criterias of choice

Before purchasing a model, you need to decide which lock you need, mechanical or electronic. When installing on a gate, it is better to choose a digital model, which has a limited number of inputs and a lot of combinations; it is more difficult to hack. It is better to install a mechanical lock with a metal panel for entering a code number on the door in the entrance or office building.

The choice of model depends on financial capabilities, however, the device must be:

Reliable.
Have the maximum degree of protection.
Contain all the operational characteristics necessary indoors or from the street.

Rating of the best attachments

For any property owner, a shutter is still the most reliable means of preventing burglary or unauthorized access to its territory. Hinged shutters are used for gates, sheds, and cellars. Locks that are tamper-evident have gained particular popularity. They allow you to reliably lock the door from the street side.

Code lock

The combination lock appeared thanks to the development of mechanics and its use is widespread at this stage. The ease of use and reliability of these combination locks, in which it is enough to enter a certain code combination for opening from the keyboard or by mechanical selection, have attracted many users and consumers. Human memory turned out to be much more reliable than a conventional mechanical key.

Types of combination locks and their features

Mechanical combination locks are the pioneers of encryption for locking and opening. By mechanically selecting numbers or letters using cylinders or keys, the mechanism is triggered and the locking mechanism is activated. These types of locks were often used until the end of the 90s and were widespread, however, technological progress in mechanics gradually began to be replaced by digital technologies and this type of locks began to gradually decline.

Electronic combination locks are new in security systems, which have replaced conventional mechanical ones due to the increased level of secrecy and a very high number of combinations reaching several billion. Now it is almost impossible to open such a device by picking or using various mechanical master keys. Ease of use did not take long to arrive and the spread of electronic combination locks became ubiquitous. Many modifications combined with mechanics and advanced technology have become a new feature of use in all areas.

Coded electronic locks with a biometric fingerprint scanner, a new combination of fingerprint scanning and dialing a special code, this development has given a top-secret level of security in locks and many global companies are already producing these types of locks.

Main advantages of combination locks

— The absence of keys and various opening devices that can be lost or damaged and the impossibility of copying these devices by attackers.

— The ability to quickly change combinations and ease of use without the need to manufacture locking devices.

— Quickly transfer the code to another person without the need to produce keys and also access to many desired persons.

— Notifying the owner via communication channels about access and advance programming by the control function of control systems

— Low probability of code selection and accidental opening, since the automatically generated signal does not give any chance to hackers and the maximum number of combinations can reach 17 billion.

— Possibility of using additional functions such as: biometric data, night lighting, remote control, hidden installation.

Many users install a combination lock as the main one and also install a mechanical one in the old fashioned way, to calm their nerves. Let us tell you that there is no need to combine these two functions, since the reliability of a combination lock is many thousand times greater than a mechanical one and the service life is also long and unique.

Combination locks have already become the hallmark of any hotel, or more or less decent establishment; convenience, modernity, functions for connecting a master password, alarm, fire safety - all this fits into one device, with high reliability and excellent user functions. Many users can no longer imagine how to do without such a functional thing. like a combination lock. Everyday use, maximum convenience, a high level of safety, as well as modern design are new, like everything that develops and brings great results.

At this stage, the combination lock is still being improved and newer and more technologically advanced devices are being invented, the technology of reading the retina of the eye is already in place, as well as the latest development of recognition by facial structure and blood vessels, everything is becoming more complex and more perfect every year.

By contacting our company, we will help you decide on the combination lock you need, select the required model and provide installation and maintenance services.

Door installation

When installing an electric lock on a door, there must be instructions describing the steps for connecting the elements of the unit.

To install the lock yourself you need:

Determine the position of the lock panel on the door.
Mark the location exactly with the lock mortise.
Cut a hole according to the dimensions of the device, put the block and locking mechanism inside.
Connect the code panel to the drive.
Route the wires and connect to the power supply.
To program the lock, set an access code on it.
Check the operation of all mechanisms in practice.

When installed correctly, an electric lock is safer, more reliable, and will last a long time.

Features and principle of operation

The essence of a combination lock is quite simple: you need to enter a strictly defined code in order for the door to open. The difference between individual device types relates to how this feature is implemented.

It is customary to highlight:

mechanical;

Regardless of this, the system will:

the locking block itself;
code receiver (or dialer);
a control system that checks the correctness of the dialed numbers (or the design features of a mechanical lock that allow it to open only when they are accurately indicated);
power supply unit (in electronic versions);
backup charging system (in electronic versions).

Do-it-yourself installation on a gate

Before installing a combination lock, you need to make sure that all the elements are present. In the standard mechanical model, the most suitable for installation in a wicket door should be:

Code elements.
Canopies.
Blocking particles.
Sliders, additional fasteners.
Hull part.

You can open the gate by typing a code on the display in a circle or pressing a button, which is more reliable; when the gate slams, the door locks automatically, but there are few combinations. There are many more of them on the typesetting circle. For a gate, a lock with a button panel, rubber, plastic, or metal, is more suitable. A steel button is usually practical and durable.

For additional protection, it is possible to have a microphone with a speaker and a backlit panel.

For installation, prepare:

Wire cutters.
Screwdrivers.
Bulgarian.
Screwdriver.
Drill, drill bits.
Ruler.
Cutting tool.

Mark the place on the gate to install the lock, mark the location of the outer and inner panels.
Secure the main part of the lock using self-tapping screws and a screwdriver. Leave an interval, a gap between the gate and the slats, of 0.3 mm.
Remove the back cover of the device, secure the lock with the handle, and put the back cover back in place.
To check the operation of the lock, select the desired combination of numbers so that you can open it. The handle and additional elements must correspond to the location of the lock during installation.

To make your measurements as accurate as possible, use a pencil striker when working.

Drill only the outermost parts of the lock so that cracks do not accidentally appear on it. If you need to install an electric lock, do not forget about safety precautions when working with electricity.

First, cables are connected to the lock.
Holes are drilled on the panel with the location of the code symbols. If you forget the code, you can recode the lock from the inside. In this case, unlike a mechanical device, the electronic model does not have to be removed.
To install a magnetic lock:
Install the bar on one of the gate leaves.
Install cables to connect the lock and the reader.
Install the lock itself.
Mount a controller outside to recognize keys or cards.
Install a button inside the gate to open the gate without a lock.
Connect the device using cables and terminals.
Protect cables from moisture by covering them with a plastic tray.

Electronic-mechanical lock Cobra

The operation of a mechanical lock can be made quite reliable and stable if you replace the mechanical coded group with an electrical one. For example, in the Cobra family of locks, a conventional cylindrical lock with a key was supplemented with a microprocessor with a magnetic lock. To open the front door, you need to insert the key into the lock and enter a four-digit numerical sequence on the dialer. If you enter the code combination correctly, the microcircuit will unlock the mechanism, otherwise you have four more attempts. If they are also incorrect, the door will remain locked for half an hour.

Despite the outward primitiveness, the electronic unit has 60 thousand combinations, so it is almost impossible to open the door by selecting a code.

Step by step guide

When installing a lock, all calculations must be accurate, and the necessary tools must be available. You will need: tape measure, wire cutters, drill, drills, pencil, pliers, screwdriver bits.

Mark the measurements with a pencil where the device will be installed.
Drill holes according to the dimensions of the lock with a drill.
Attach it to the door.
Insert the bolt into the strike plate.
Connect the cable to the device.
Use a screwdriver to attach the handle to the lock itself.
Replace the cover.
Enter a code.
Check functionality.

Do not drill holes too close to the edge as this may cause cracks and splits. A gap must be left between the crossbar and the end part. The work must be carried out as accurately and accurately as possible.

If you forget the code, you can remove the cover from inside and reset the code. Take out the plates and turn them over in the opposite direction, this will be more convenient and reliable; you should program the lock according to a scheme convenient for you.

Foolproof protection

If, while typing the code, any of the “wrong” buttons (S1-S5) is pressed, voltage is applied to pin 15, which resets the counter, returning the entire circuit to its original position. This is not displayed in any way on the indicators, which makes password guessing much more difficult.

Unauthorized access can be made almost impossible by simply adding a time relay to pin 15, quietly blocking all keys for at least 60 seconds.

In this case, if you enter the code incorrectly, you will have to wait a minute before entering it again. The attacker will not know this, and even if he accidentally guesses the password, it is not a fact that he will type it while the time relay is inactive.

If you know about this feature, then it will take 10-12 thousand minutes to select a password - you will have to continuously enter passwords for about 8 days to select the desired combination. The reliability of such a solution increases almost to its maximum values.

The assembled circuit is only part of the work - now you need to adjust the opening/closing of the lock bolt. To do this, you can either make a magnet or use a ready-made activator, for example a car one.

Using these methods, you need to be aware that in the first case, when there is a power outage, the lock of the front door will automatically open, and in the second case, on the contrary, it will remain closed. Therefore, the second option, equipped with a UPS, is more preferable.

User manual

The environment can negatively affect the device; at low temperatures it may freeze and be difficult to open. Mechanical locks are reliable and you don’t have to worry about breakage.
If any malfunction occurs, take the lock to a repair service and they will fix it.
There is no need to repair it yourself, especially electronic locks; diagnostics can only be carried out by a professional who may replace failed elements and reinstall the program.
Complex structures are expensive and difficult to repair; there are many different components.
To recode a mechanical lock, you need to remove it, which is also troublesome.
Before purchasing a device, pay attention to all possible nuances.
Remember that any devices are imperfect, they require correct installation, otherwise they will quickly fail, cause unnecessary trouble and ruin your mood.

Code change

This process is most simple with padlocks. It is necessary to rotate the open arm 180 degrees, snap it into place, turn the plates to set the digital dial and wait for the arm to click. You can use the new code.

On mortise and overlay devices, the operation of the locking device is determined by the position of the bevel of certain crossbars towards the middle of the lock. The remaining crossbars are installed with the beveled edge outward. To change the code, it is necessary to dismantle the lock, disassemble it and change the location of the bevel of the crossbars. You can do everything yourself.
