A sensible approach to copies, records, and the point where rekeying is more appropriate. Written for North 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 North Vancouver
In North Vancouver, multi-unit buildings, hillside homes, and commercial entries each bring distinct hardware and authorization considerations to an access request. North Vancouver homes, strata buildings, retail spaces, and service vehicles all have different access needs. Describe the problem and the hardware before work is chosen.
