Master Key Systems
A master-key system is an access-control structure. Poor planning creates uncontrolled access and future rekey costs; professional planning begins with doors, users, levels, key control, and change procedures.

Clear information helps match the right tools and technician before the appointment is confirmed.

Questions people ask before booking
What is the difference between keyed alike and master keyed?+
Keyed-alike locks use the same operating key. A master-key system allows different user keys plus one or more higher-level keys.
Can an existing property be master keyed?+
Often, but cylinder compatibility, current keyways, hardware condition, and desired hierarchy must be audited.
How should master keys be controlled?+
Limit authorized holders, record issuance, define duplication rules, and rekey promptly when a high-level key is lost.
What should be tested before the technician leaves?+
Test every affected function related to master key systems, review any remaining limitations, and make sure keys, locks, doors, remotes, ignition functions, or access hardware operate as expected before the service is closed.
