Master Key Lock

Master key or master keying is the capability to use one "Master" key to open one or more locks that are not actually keyed the same. A master key system uses security key blanks that are precisely designed keys which could only be duplicated only from a locksmith who created the system.

Apartment owners uses master keys to open each door of their rented apartments, and on the other hand, each tenant also have a key to their own and specific unit. Tenants's key may also be used to access the main door of the building along with other areas accessible to renters. Unlike Master keys, a tenant's specific key will not work on the lock of a different apartment unit.

Master key systems also involve grand master and sub master keys. If you want to have one key to all different doors, then master key is what you need.
