Start with the reason for the change
A staffing change, missing key, tenant turnover, or unclear key history often calls for a rekey. Rekeying changes the cylinder so old keys stop working while compatible hardware remains in place.
Replacement makes more sense when hardware is worn, damaged, difficult to operate, or no longer matches the level of control the property needs.
Look at the complete opening
A lock problem can begin with a sagging door, misaligned frame, failing closer, or damaged exit device. Before buying new cylinders, have the complete opening evaluated.
For several doors, document who needs access and where. That information can turn a reactive repair into a useful master key or restricted key plan.
Plan for the next change
Commercial security should support turnover and growth. Ask whether the new system can expand, how duplicate keys are authorized, and how changes will be documented.
