When the question arises about the safety of your home, the price factor involuntarily recedes into the background. Acquiring a lock on the front door, the buyer is guided by two main criteria. Firstly, it must be a really reliable locking device and, secondly, that after installing it, it is not easy to penetrate the house by the method of selecting keys or using a master key. Proceeding from this, we will figure out how to choose the right lock for the entrance door and what to provide.
Further accent - on the choice of locks for the entrance doors of apartments and houses. What to use to ensure the safety of various subsidiary buildings( premises), the owner will be able to determine himself.
Classification of locking devices
By the way of opening
- Biometric. The most expensive models of locks. Identification is made on fingerprints, scanning the retina of the eye. Reliability is high, but there is also a minus - it is necessary to ensure continuity of power / power.
- Magnetic. The key is a special card. Transcoding of such a lock is made by the user. It should be noted that such cards must be kept in compliance with certain conditions. Demagnetization will cause the door to open at the right moment.
- Pushbutton. To make the lock work, you need to dial a certain digital combination( code).Such devices are mechanical and electronic. Ease of operation is that at any time you can change the lock code. Plus, you do not need to carry a key with you all the time. Minus - experienced crackers on the worn-out buttons can easily determine the required digital combination.
- Mechanical. Traditional, familiar and most common locks. Their opening / closing is done by a key.
Specific to mounting
- Overhead. Such models can be installed at the entrance to the apartment. But you need to consider that the fastening of the product to the canvas( how to choose a reliable metal door) should be as reliable as possible, and the lock - rather bulky. Otherwise, the door will be easy to knock out a few blows. For a country house, given the remoteness and possible absence of neighbors, such locking devices clearly do not fit.
- Mounted. The cheapest, yet reliable locks. But they are no longer installed on the front door of the dwelling. It is unlikely that anyone will mount the hinges on the frame and canvas and hang such protection.
- Mortise. This type of locks is recommended for all entrance doors to dwellings. For metal, especially bulk, with insulation - the only possible option.
On the level of secrecy
- Low. The key to this lock is easy to pick up, since the number of possible combinations of larvae is relatively small.
- Medium. The best option, especially as the cost of such locks is quite affordable for the average consumer.
- High. Dear models of locks, to which pick up a master key or to forge a key is almost impossible. Even if you make a cast beforehand, you will need an additional adjustment of the key to the lock.
Security class
- The first is the simplest locks, which will not become a particular obstacle for the attacker.
- The second is a more difficult option, although the professional will have 5 minutes to pick up the master key and open it.
- The third - given the reliability and reasonable price, such locks are considered to be the best option for entrance doors. With a product from a well-known manufacturer, the burglar is carried for at least ⅓ of an hour. Practice shows that, faced with such a model, most apartment thieves prefer not to experiment.
- Fourth - the most reliable, but also the most expensive locks. To open such a device, you need not only to prepare well, but also to have a special tool at hand. It will be necessary, as practice shows, at least 30 - 40 minutes.
According to the configurations of the
- locks. The simplest version of the fixing elements.
- Rigel. As a rule, there are at least 3 of them, and such devices are much more reliable.
The reader has already received all necessary information on locks. But is this enough to properly choose a truly reliable design? One of the main criteria for the security of the door is the complexity of the "filling" of the castle. It is she who is the main factor of safety. Here on this and should be discussed in more detail.
Types of locks for entrance doors
Suvaldnye
Such locks are mounted by the method of tie-in and are considered one of the most reliable and convenient in operation. If the key is lost, the door can be opened by picking the master key, without removing the canvas, although it will take quite some time. Cons - the significant size of the key and the massiveness of the product, since the reliability of protection directly depends on the dimensions of the lock. But these models are most often installed on the entrance doors.
Cylinder
Another popular lock for the front door.
Pick a key or a picklock is quite difficult. But in terms of maintainability, such models are preferable to many others. If the keys are lost, then it is enough to replace the "larva" and make new ones.
Electromagnetic
They are known to many, as similar models are everywhere installed on the entrance doors to the entrances of houses.
Have limited use, because in the absence of a commercial / voltage opening is not protected.
Electromechanical
Such locks are excellent for private buildings, since remote control of the opening of the entrance door is possible.
But it is advisable to use them only as part of the kit. The call device is installed at the entrance( to the site), and the receiving device is installed in the house. Otherwise, such a lock is no different from the usual mechanical model. If there is no power supply, it is the key that opens the door.
Combined models
They combine the elements of the locks of the lever( ensure the reliability of the lock) and cylindrical( the complexity of unauthorized penetration with a master key).
There are several other designs of locks. For example, disk.
But at the entrance to the dwelling they are not advisable to install due to the low level of protection provided. The same can be said about the cruciform models. In appearance, they differ little from the locks of the saddle. 
The difference is in the "stuffing".Such models are less reliable, as they are often opened using screwdrivers "under the cross."For the entrance door of an apartment house( apartment) it is advisable not to purchase, especially if such a lock will be the only one on it.
Useful advices
According to experts in the field of security, the best option is to install on the front door locks cylinder( pin) and sovaldnogo.
Buying a lock, you need to focus and on the specifics( location) of its installation. Unfortunately, domestic models are still inferior to imports in many respects. If we are talking about the entrance door of a country house, it is better to choose locks of a foreign manufacturer. They are more expensive, but they provide a higher security. For a city apartment, especially since many entrances are closed by metal doors( plus neighbors), you can buy a lock easier.
Why? It's all about the specifics of production and the desire of the manufacturer to reduce the cost of production. Therefore, even in different types of locks of the same company there are similar systems, which facilitates the selection of keys( master keys) and opening the door.
If the product is installed on the entrance door of a country house, then you need to choose at least one lock of the 4th class. Security( in conjunction with security alarms) will be at the proper level. For buildings in the city in order to optimize costs, it is recommended to install two class 2 or 3 locks.
When choosing a lock, one should also take into account the moment when it is possible to make duplicate keys. They are bundled, as a rule, from 3 to 5. Enough? After all, not only children, but also adults often lose them. If the key configuration is rather complicated, then the lock must be dismantled and carried to the workshop. Otherwise, there is no guarantee that the master will make a duplicate so that he immediately opens the door. Therefore, buying a device, focusing only on the unusual key, is hardly worth it. Especially in view of the fact that almost in all houses( apartments) on the entrance doors the owners set at least 2 locks.
