Rekeying After a Staff Change: A Checklist for Small Businesses

Someone has left and the key has not come back. Or it has come back and you have no way of knowing whether it was copied.
This is the most common commercial call we take, and it is usually smaller and cheaper than people expect — if you change the right things.
What does a commercial rekey cost?
Per cylinder, commercial rekeying runs in a similar range to residential work — roughly $25 to $50 each once a technician is on site, with a call-out fee on top.
The variable is how many doors are involved. A single storefront with two exterior cylinders is a short visit. A suite with interior offices, a stock room and a rear exit is a larger one.
Work outside trading hours costs more, and is usually worth it: the alternative is closing the doors during the day.
Work out what they could actually open
The checklist
- List every door that key opened, including any padlocks and cabinets
- Check whether a master or grand master also opens them, and whether it needs to keep working
- Rekey those cylinders and issue a new key to each person who still needs one
- Write down who received which key and have them sign for it
- Change alarm codes and any keypad entry codes at the same time — these get forgotten more often than the keys
- Remove the person from any access control or building intercom system
- Collect keys for anything else they held: post boxes, cash drawers, vehicles, gates

Frequently Asked Questions
No, and you usually should not. Only the cylinders that key could open need changing. Working out which is the first thing we do on site.
Yes. Most commercial rekeys are done after closing or before opening. Tell us your hours and we will work around them.
A planned hierarchy where each key opens a defined set of doors — a member of staff opens their own area, a manager opens more, and one master opens everything. It means a departure can be handled at one level without touching the rest.
Keys whose blanks are controlled, so they cannot be copied at a hardware counter. Copies are issued only to the registered holder, which removes the question of whether an unreturned key was duplicated.
Same day is usually possible for a rekey after a staff departure, and we can schedule around your opening hours. Tell us how many doors are involved, and the technician will give you the price on site, before any work begins.
