Lock rekey & Master key systems

Beschreibung

Replacing a lock is self-explanatory: the locksmith changes your old hardware with a new one. Rekeying, on the other hand, is a bit different – the locksmith replaces the working key of the lock but keeps the same lock. The lock is, however, taken apart and some parts inside are replaced (the “key pins” or “tumblers”). A master key system references a group of locks, and the keys that operate them, which are related in a hierarchy with one key at the 'top', which will fit into a large number of locks; and a large number of keys at the 'bottom' which may only fit into one lock. The fewer master key levels, the more secure the system.
