The door is the heart, the lock is Paul Dean, there are three keys, decoration keys, their own keys, there is a copper key, the problem is now with their own keys and decoration keys can open the door, and copper key From the outside can be inserted into, but twist does not move, from the inside can be twisted, who can tell me how to make the decoration key failure!
You use your own key from the outside into the inverted 360 degrees, the decoration of the key is useless, yellow is used to search with the key with the
The warranty key of the Bodean lock cylinder is only for the outdoor side. And I can tell you plainly that there are only two sets of keys A total of eight, of which two copper keys, that is, decoration keys, another good packaging 6, that is, the main key. There is no so-called three sets! Failure method: insert any of the main keys into the outdoor keyhole, rotate 360 degrees after the decoration key will automatically fail. Indoor side can not be invalid.
After the renovation, with the B key (whether it is closed or open the door) in the door into the keyhole lock cylinder rotation above 360 degrees on the line, and then return to pull out the key, and then take the A key into the keyhole to see if the rotation was moving , The rotation does not move to explain the A key to lose the role, you can destroy the A key, do not litter (knowledgeable people can still take to make the key to unlock). If the A key can also rotate on the instructions can unlock, and then repeat the previous operation on the line.
