A sensible approach to copies, records, and the point where rekeying is more appropriate. Written for Vancouver, British Columbia.
Copies solve a convenience problem
Spare keys make sense for current authorized users and planned contingencies. Keep a simple record of who has them, especially for shared homes, suites, and small businesses.
Missing keys are a security problem
If keys are lost or former occupants still have them, the better response may be rekeying compatible cylinders. That changes the keying without necessarily replacing every piece of hardware.
How this applies in Vancouver
In Vancouver, condo and strata requirements, dense commercial blocks, and shared building access often add an authorization or hardware detail that is worth clarifying early. From condo lockouts and strata moves to storefront door hardware and vehicle fobs, Vancouver calls need a practical mobile locksmith plan.
