Reliable locks for entrance metal doors: 5 best manufacturers

Today, many owners of apartments and private houses, worrying about their own safety, install metal or armored doors. But the fact is that the protection of housing depends not only on the installed door leaf, but also on the chosen locking device. If the lock was chosen incorrectly or turned out to be of inadequate quality, the burglary resistance of such a door instantly drops. Therefore, it is very important to understand the mechanism of operation of locking devices and make the right choice.

When choosing locks for metal entrance doors, it is necessary to take into account the parameters that relate primarily to the device and the protective properties of these locking mechanisms.

Door locks are distinguished by:

• Appearance;
• The mechanism of work;
• installation method;
• Reliability class.

Outwardly, castles can look completely different - this applies to both their size and the level of visibility. For example, there are special hidden keys that are not visible to prying eyes.

As for the mechanism of operation, on this basis, locking devices are divided into:

1. Crossbar locks - in order to unlock such a device, the key should not be turned, but inserted into the keyhole until it stops. The keys for such locks are made long, having special teeth and slots.
2. Cylinder - the most common locks. They need small keys, and the fact that such a mechanism is almost impossible to crack with a master key gives them an additional advantage.
3. Suvaldnye - represent a plate from which a certain number of constipation is advanced. The more such bolts a lock has, the more reliable it is.
4. Electronic (electromagnetic) - as a rule, they are opened with a certain combination of numbers or a magnetic key. Such a lock has an automatic principle of operation, which allows it to close the doors automatically. Its disadvantage lies in the direct dependence on the supply of electricity.

According to the method of installing locking devices, the qualities of mortise locks showed themselves best of all. Their hidden parts located inside the mechanism serve as an excellent barrier to the actions of an intruder. Overhead locking devices are used less often for metal doors, as they are not as reliable. They are mainly used to lock interior doors.

There is a classification of locks according to their reliability. There are four classes:

• The first and second classes are not suitable for iron doors, as they are very simple and easy to break.
• The third class is distinguished by increased burglary resistance, and it will take at least 10-20 minutes to open it.
• The fourth class is the best, and in order to crack such a door, you will have to suffer for about half an hour or more.

When it becomes necessary to choose a lock for the front door, you must, first of all, look at its resistance to breaking and reliability. The ideal option is when two types of different locking mechanisms are installed on the door: one main and one additional.

High-quality front door lock cylinder and criteria for its selection

The lock cylinder is a special code part of the lock mechanism, which is “responsible” for the secrecy of this design and moves the bolts. In common parlance, it can be known as a "larva".

In order to choose the right cylinder, you need to know its main parameters:

1. Length - it must necessarily fit the thickness of the doorway and the lock.
2. Displacement - The cylinder is usually split by a pendulum, which is displaced to one side, dividing the device into two parts. You need to choose an offset that would fit the castle.

When choosing a cylinder, it is important to consider one point: the design should not protrude beyond the plane of the door. The maximum protrusion of the larva can be equal to 3 mm, not more. Otherwise, attackers will easily take advantage of this visible part.

The main obstacle to burglary is the secret details of the locking mechanism, so there is no need to save on what ensures the safety of your apartment.

The main methods of lockpicking, and what precautions should be taken:

1. Master key - tricky false grooves will help here, significantly slowing down the process of selecting a key.
2. Drilling or knocking out - against this method, buying a cylinder made of a metal that cannot be drilled and is resistant to physical impact can help.
3. Bumping (the key inserted into the well is beaten with a hammer) - and again the strength of the cylinder itself and a non-standard, possibly hidden well, play a role here.

As you can see, with the help of a properly selected cylinder, you can protect your apartment as much as possible from the intrusion of unauthorized persons and the commission of a crime.

To put really high-quality and reliable locks, you should not only study their types and equipment, but also listen to the advice of the pros.

So, what should be considered when purchasing door locks:

1. The thickness of the door leaf - if the leaf is less than 4 mm, you should not buy a very heavy and large lock.
2. Types of locks - it is best to make your choice in favor of cylinder and lever locking mechanisms, as they are characterized by increased burglary resistance.
3. Manufacturer's warranty - when buying a lock, it is necessary to check the availability of a quality certificate, which must specify the materials used in the manufacture and the reliability class.
4. The appearance of the key - in a good lock, the key has many teeth, notches and grooves, so a too simple appearance of the key may indicate a poor-quality mechanism.
5. The lock case - the metal must be strong and thick, if the material is soft and brittle, then most likely this lock is for an interior door, and not for an entrance door.

If you want to put several locks on the door, then you do not need to buy them of the same type. Lever and cylinder locks or mechanical and electromagnetic locks are ideally combined with each other.

Understanding the principle of operation of locks, their types and characteristics, you can protect yourself and your home from unwanted guests and the damage caused by them.

How to put a lock on the front door

Before you buy a lock and invite a specialist to help you embed it, you can independently understand all the intricacies of such an installation. If you have little skills, you can do it in just a couple of hours.

Of the tools you will need:

• Bulgarian;
• hacksaw for metal;
• drill;
• self-tapping screws, corners, ruler;
• Castle.

All work begins with the dismantling of the old locking mechanism, after which you can proceed with the installation of a new one.

First you need to attach the lock to the door and transfer all its dimensions. This is best done with chalk or a special marker. After that, you can start drilling the hole.

In this case, you need to know that the hole should be slightly larger than the lock itself. But the main thing here is not to overdo it, otherwise, over time, the screws may become loose, which will affect the operation of the device.

Holes for crossbars must be made with extreme precision and care. As a rule, this is done with a drill and a grinder.

When the lock is in the niche made, it is necessary to firmly fix it there on the slats and to the door with self-tapping screws. After that, you can install the top closing bar that hides the lock from prying eyes.

After installing the lock, be sure to check its operation. The key should turn smoothly and easily, and the door should be firmly closed.
