The lock core of the door lock is only the front unlocking position, does it not include the inside?

The lock of the security door is divided into three parts: lock core, lock body and handle.

The one installed on the door is called the handle, which is symmetrical inside and outside when it is used to open the door.

On the side of the door, the whole that is seen and extended is called the lock body.

The key-twisting part is called the lock core, and it runs from the key-twisting place outside the door to the key-twisting place inside the door.

Please change the lock cylinder before moving into the new house.

1. Most of the doors and lock cores provided by the developer are engineering doors, which are subcontracted at the first level. They usually have very cheap locks to control costs. These locks are all Class A lock cores, which can be opened in one minute technically.

2, the most primitive decoration keys, developers, decoration workers, property and so on. You may have prepared your own decoration key, which may still open your door.

3. Experienced people can match the master key according to the decoration key.

4. If you think the original door is not good and the economic conditions allow it, you can consider changing it. But after changing the door, you should still consider changing the lock. Thousands of people bought a door and a dozen people carried it home to install it. As a result, the lock on the door is still the same or the same level as the lock of the developer. The thief looked at it and smiled. You are the only one who changed the door upstairs and downstairs, which stands out. Replace the B-class lock core to ensure foolproof.
