Why do fingerprint locks use mechanical keys as an emergency unlocking method? Is this different from a mechanical lock? Is it really a mechanical lock with electronic function?

Because the Ministry of Public Security has made it mandatory for any door lock: fingerprint lock, password lock, hotel sensor lock, remote control lock ..... to be equipped with a mechanical key, so as to avoid power failure or malfunction of the lock, you can use the mechanical key to open the door.

At present, the use of fingerprint office or password lock is:

To make people's lives more convenient is to go out without a key. Rather than simply considering the anti-theft performance. So if but from the point of view of anti-theft performance, (at present) fingerprint lock or password lock has no advantage.

Extended data:

function

Choosing the function of the lock, on the one hand, is to meet your own needs, on the other hand, it is also related to the quality of the lock.

A good enterprise often has at least five kinds of fingerprint locks from high school to low for users to choose from. Users usually choose to use their own products: some are used for entrance doors, divided into metal doors and wooden doors, some are used for user interior doors, some are commonly used for wooden doors, and some are also used for villa doors. Commonly used basic functions are:

(1) can be used for multi-fingerprint door opening (there are often more than one or two people in a family or office), and the product quality should be stable and the performance should be good;

(2) You can open the door with different permissions (householders can't have the same management permissions as nannies and cleaners);

(3) You can freely increase or decrease the fingerprint of opening the door (the nanny can easily remove her fingerprint when she leaves her job);

(4) It is best to have the inquiry record function (you can check the knocking record at any time, sometimes it can become key evidence, and generally you need to bring a display screen);

(5) Bring a password function appropriately (the fingerprint part may be cracked after all, and the householder can open the door with a password under temporary circumstances). Try not to choose a product that highlights the password function too much. After all, passwords are not as secure as fingerprints. There are usually two kinds of keys: 4 and 12. Try not to open the door with a password in daily life.

(6) Be sure to bring a mechanical key, which is an alternate way to open the door. Like airplanes and cars, although they have automatic control status, they still retain the manual control part. This is for security reasons:

Any electronic part is likely to make mistakes, and the mechanical part is much more stable. As a backup way to open the door at home, the mechanical key with the lock can open the door in time when the electronic part of the door lock breaks down, which is convenient for maintenance. Imagine what would you do if there was a fire in your house, or if a thief damaged the electronic part of your house because he didn't pry open the lock?

Never covet the so-called psychological safety, regardless of the back road, choose a door lock without a mechanical key.

In fact, the most important thing to use fingerprint lock is not to improve security, but to enjoy the convenience of fingerprint lock. If you need to strengthen the security of fingerprint lock, you can access the smart home system. Some fingerprint lock manufacturers reserve development ports for fingerprint locks. In smart home, the status of fingerprint lock can be monitored in real time only by developing fingerprint lock, thus improving the security of fingerprint lock.

(7) Select a good lock cylinder. The quality of mechanical key lock cylinder is directly related to the prying resistance and stability of your door.

This part is also very important. No matter how good the fingerprint lock is, it is still inseparable from the lock core. Under normal circumstances, powerful fingerprint lock manufacturers will choose high-grade lock cores, so that the quality of products will be guaranteed. The most obvious thing is that consumers can look at the number of marbles and the number of deep and shallow files of the key. Try to choose products with many marbles and deep files.

The number of marbles with different depths is the number of keys of this mechanical key. The greater the number of keys, the better the security. National standards generally require at least Class A locks, and good fingerprint lock manufacturers are generally equipped with super Class B mechanical keys.

GA374-200 1 electronic anti-theft lock standard

This standard specifies the technical requirements and test methods of electronic anti-theft locks. This standard is applicable to locks that use electronic information and its carrier as "keys" to control the opening and closing of mechanical locking structures by electric means.
