Schlage warns its customers that in most cases it is not possible to repair a broken lock mechanism. Instead, owners of Schlage safes should replace the lock mechanism entirely.
Replacing the lock mechanism of a Schlage product is not difficult for an amateur carpenter or handyman. First, determine the hole size for the knob, lever, deadbolt or handleset and the distance of the latch backset. The deadbolt hole is likely to either be 1 1/2 inches or 2 1/8 inches in size. If the safe door opens, replace the lock mechanism from inside the safe. If the safe door does not open, only an authorized locksmith can open it, and then only if the damage to the lock mechanism is not severe.
More complex systems, such as electronic door systems, are also beyond the ability of the average handyman to replace. Electronic Schlage locks carry preset program codes that can be used to troubleshoot a variety of problems, but must be physically removed from the safe to expose the code label located on the back of the keypad assembly. Each electronic lock comes with a unique set of preset program codes, produced by a random algorithm, that is either four or six digits.
