The house is filled with a step anti-theft door lock with AB. Decoration is the use of A keys, now decorated, and want to use the B key, on the Internet to see, but that the master with B key inserted into the lock, turn the lock core after a turn (circle), the A key will lose the unlock function, please. 1, B keys need to use the A key first open the door lock, or lock it? 2, B keys are inserted from the interior into the keyhole, turn the lock a turn (circle), or from the outdoor plug into the keyhole, turn the lock a turn (circle)?
Just insert the B key with the notch, turn it counterclockwise, and it doesn't matter inside and outside! It doesn't matter whether the lock is locked or not!

A can destroy the key, do not throw (or knowledgeable people can take to produce the key to unlock the). If the A key can rotate, it shows that the lock can be unlocked, and repeat the front operation. (all this is for AB keys, and one for ABC keys.)
After the renovation, with the B key (either closed or open the door) at the door in the lock lock core is rotated 360 degrees above the line, and then return to pull out the key, then take the A key into the keyhole to see if the rotation move, rotation does not move that A key lost its effect,
