Where is the safe place to change the lock cylinder?

Why will the lock cylinder be stolen after changing the lock cylinder? This may be caused by the following two reasons. First, the replacement lock cylinder is of poor quality and not very safe, and can easily be pried open by thieves. The lock cylinder has a security level, the A-level lock cylinder is safe, the anti-theft lock level needs to be B-level, and the anti-theft lock cylinder is super B-level. This reminds us to pay attention to the security level when purchasing a lock cylinder.

The second reason why the lock cylinder is stolen after changing is that the person who changes the lock is not a regular practitioner. Some criminals use the name of a locksmith company to deliberately leave loopholes when installing and changing locks for residents, and then they can easily enter and commit theft when the residents are not at home. Therefore, when looking for someone to replace the lock cylinder, you must find a regular company and don't just look for it from small advertisements on the roadside. When staff come to the door, they must check their employment certificates and ID cards, as well as certificates from relevant departments.

Things to note when changing the lock cylinder

1. When changing the lock cylinder of the anti-theft door, special attention should be paid to the size of the door lock cylinder. After measuring it, buy the same one. Replace the lock cylinder with the size of the lock cylinder. If the size is not correct, the newly purchased lock cylinder cannot be installed, which is very troublesome.

2. The feel of the door lock is determined by the spring. The quality of the spring determines the feel and service life during use. Some lock springs are not good, so it is easy to cause the handle to sag, thus ending the life of the door lock. When purchasing, you should try the toughness of the door lock spring in person. A good spring will have a very soft feel, not too soft or too hard.

3. When replacing the lock cylinder of the anti-theft door, special attention should be paid to the size of the door's lock cylinder. After measuring it, buy a lock cylinder of the same size for replacement. If the size is not correct, the newly purchased lock cylinder cannot be installed, which is very troublesome. If you ask someone else to change the lock cylinder, for the sake of safety, avoid others from hiding the key

You must pay attention to safety when changing the lock cylinder. If it is not a brand security door and you cannot find a professional brand master, don't find some. Ordinary locksmiths not only do not know the level of their professional knowledge, but they also cannot guarantee safety. Regular lock replacement and locksmith stores are registered with the Public Security Bureau, which is more reassuring. When replacing the lock cylinder, pay attention to the size of the lock cylinder. If the size is incorrect, it cannot be installed. If the lock cylinder is forced to be installed, it will cause damage to the door. Even if you change the lock cylinder, you should also know the key well.
