Common questions
Before you request this service.
These answers describe our usual scope. The existing door, hardware and site conditions determine the final recommendation.
What is the difference between rekeying and a master-key system?
Rekeying changes which key operates a cylinder. A master-key system organizes cylinders so individual change keys open selected doors while authorized master keys open a broader group.
What does a restricted-key system change?
A restricted-key system uses controlled key blanks and an authorized duplication process to reduce uncontrolled copying compared with common, unrestricted keys.
Can a master-key upgrade be completed in phases?
Yes. For occupied or multi-door properties, compatible cylinders can often be rekeyed or upgraded in planned stages around access needs and daily operation.
