Rekey vs Master Key: What's the Difference?
Rekeying and master keying are often confused. Here's the clean version.
Rekeying basics
Rekeying changes the pins in a lock so old keys stop working and a new key works.
One lock, one new key.
Master keying basics
Master keying pins multiple locks so different keys open different doors, with a master key opening them all.
Multiple locks, tiered keys.
When to use each
Rekey after a move, a lost key, or a security incident. Master key when you have multiple doors and want tiered access.
Different problems, different tools.
Combining them
The two are commonly combined: rekey all doors as part of installing a new master system.
One visit, one solid outcome.
Cost comparison
Rekey is cheap per lock. Master keying costs more because of design and coordination but scales better long-term.
