Usually a security door has 2 A keys, 5 B keys, and 1 C key. The A key, also known as the "worker's key back", is used by workers during renovation. Answer: At the end of the decoration, use the C key to turn around in the lock, the A key will automatically become invalid, and you can only use the B key to open the door. >>>More
Let the worker use the A key, after the decoration is completed, use the B key "waste A key", after the B key is lost or broken, use the C key to open the door "waste B key", and then change the lock core.
During the renovation period, the decoration key has been used, and the door key is not used first, and it is locked with tongue reeds. Once the decoration is completed and there is no need to be in the acceptance, you can discard the decoration key, use a new unopened key, and the decoration key will not open the door.
Check again the status of the door opening The key is inserted from the outside Turn left to the head Turn to the right Turn the head and then reset The key is inserted in the pull out.
Look at your lock model, the question is too general, and the bad lock cylinder 20 or 30 can be bought. It's as expensive as 1000 or more. Find a lock picking company, they generally provide lock cylinder and installation services.
