At first, the fingerprint combination lock can replace the lock core. According to China's hardware lock product standards, fingerprint combination locks are emergency mechanical locks. Mandatory requirements of the Ministry of Public Security: all door locks must be equipped with mechanical locks to prevent power failure or failure of the locks, and the doors can be opened with mechanical equipment keys. Therefore, all anti-theft locks have a lock core, so the fingerprint combination lock can also change the lock core.

Second, what is the lock core? It is the key component of the operation lock opening, the cardiovascular system of the hardware lock, and the key component of the supporting facilities with keys to rotate and push the lock.

Finally, for how to replace the lock core, there are several small processes:

Step 1: Before changing the lock core, please prepare 1-2 screwdrivers (one straight, one cross);

Step 2: First remove the panel, and then remove a lot of pressure pads on the inner panel of the anti-theft lock (note: when removing the last screw from the inner panel, do not let the outer board fall on the ground to avoid damage);

Step 3: Remove the lock core until there is a bolt in the middle of the lock core baffle on the door frame. In the middle of the lock tongue, remove the lock core and replace it with a new one;

Step 4: Simply rewind the clothes in the order they were unloaded. After installation, the front of the lock core should be on the same plane as the panel.
