What Should I Do When an Employee with Keys Leaves in Louisville?
Rekey every lock that employee had access to. Do it before their last day if possible, or at minimum the same day they leave. This applies whether the departure was friendly or not. A key that was returned can still have been copied — most hardware stores cut copies in under two minutes, and there is no way to verify a key wasn’t duplicated during the employee’s time with you.
That single action — rekeying — is the most important step. Everything else in this post builds on it or supports it.
Bowles Locksmith Service Louisville has handled this exact situation hundreds of times for businesses across Louisville and surrounding Jefferson County. The calls come from restaurants after a manager walks out, from medical offices after a front-desk employee is let go, from warehouses, retail shops, law firms — any business where keys get handed out as part of the job. The pattern is always the same: the employer waits too long, then something happens, and they wish they hadn’t waited.
Why Returning the Key Is Not Enough?
A lot of business owners assume that getting the key back at the end of a termination meeting closes the loop. It doesn’t.
Physical keys are cheap to copy and easy to copy without detection. If an employee worked for you for six months and wanted a copy of your building key, they had six months of opportunity. You have no way to audit that. Accepting the key back is good practice — it removes one copy from circulation — but it doesn’t account for copies you don’t know about.
The only way to truly close access is to change the locks or rekey them. Rekeying is typically the faster, more cost-effective path. A qualified locksmith disassembles the lock cylinder and replaces the internal pins so that old keys no longer work. Your existing locks stay in place; only the pin configuration changes.
How a Master Key System Complicates Things?
If your business uses a master key system, a departing employee with a master key or a high-access key creates a bigger problem. Master keys are often cut to fit multiple locks across an entire building or suite. Rekeying just one door isn’t enough in that case — you may need to rekey every lock that falls under that key’s hierarchy.
This is where it pays to have your key system documented before a departure happens. At Bowles Locksmith Service Louisville, we see businesses that have never mapped out which keys open which doors. When a senior employee leaves, they’re scrambling to figure out what that person actually had access to. That’s a stressful, expensive situation to be in.
If you don’t have a documented key control plan, a commercial locksmith can help you build one. It takes a few hours to audit a typical small or mid-sized office, and it means future departures are much easier to handle.
What to Do in the First 48 Hours?
Start with physical access. Walk through every space the employee could enter and note which locks they had keys for. Include back doors, storage rooms, server closets, and any exterior gates — not just the front entrance.
Then call a qualified commercial locksmith and schedule a rekey. In most cases, a locksmith can rekey multiple cylinders in a single visit, so you’re not dealing with repeated service calls. If the employee had access to a safe or a combination lock, change those combinations too. The process for changing a safe combination is straightforward for a professional and should not be skipped.
While you’re at it, check electronic access. Key cards, door codes, and app-based entry systems all need to be updated separately. A locksmith handles physical locks; your IT or building management system handles digital credentials. Don’t let one distract you from the other.
A Real Scenario from Louisville
A retail business in the East End had a store manager leave after a disagreement. The owner got the key back at the termination meeting and considered the matter closed. Three weeks later, a night-time break-in occurred. Nothing was definitively proven, but the point of entry was the back stockroom door — a lock the former manager had a key for during employment.
A rekey on the day of termination would have cost a fraction of what the business spent on repairs, inventory replacement, and the time lost dealing with the aftermath. This kind of situation is not rare. The ALOA Security Professionals Association, which represents trained locksmiths across the country, consistently advises businesses to treat employee departures as a security event requiring immediate action on physical access.
Key Control Going Forward
Most businesses that call us after a bad departure end up asking the same question: how do we prevent this from happening again? The answer is a documented key control policy.
At a minimum, that means keeping a written record of every key issued, to whom, and for which locks. It means requiring employees to sign for keys and sign off when they return them. It means establishing a policy — ideally in writing in your employee handbook — that any departure triggers an immediate security review. Some businesses go further and use restricted keyways, which are key blanks that cannot be legally duplicated at hardware stores without authorization. The Builders Hardware Manufacturers Association and standards from ANSI both provide frameworks for graded commercial hardware that supports better key control.
None of this needs to be complicated. A one-page internal policy and a habit of rekeying after departures eliminates most of the risk.
Should You Upgrade While You’re at It?
A departure is a natural moment to evaluate whether your current locks are doing the job. If your building has older hardware — particularly residential-grade locks on commercial doors — a professional can assess whether upgrading makes sense. Commercial-grade locks are built to different tolerances and rated under stricter standards than residential hardware.
Commercial door installation and repair can address door frame issues that make even a well-functioning lock vulnerable. A lock is only as strong as the door and frame it sits in. If a door doesn’t close square or the strike plate is loose, a rekey alone won’t solve your security problem.
Get It Done Now, Not Later
The instinct to handle this next week is understandable — there’s a lot going on after an employee leaves. But physical access control is the one thing that’s genuinely time-sensitive. Every day that passes with a former employee potentially holding a working key is a day of unnecessary exposure.
