Why a departure is a lock question and not only an HR question
Most owners think about an employee leaving as a paperwork event: final paycheck, return of equipment, removal from payroll. The doors tell a different story. A lock does not know who works for you. It only knows whether a key fits the pins inside the cylinder, or whether a fob or keypad number is still active. Until something changes, a former employee's key opens the door exactly as it did on their last day.
That does not mean every departure is a threat. Most people leave on good terms, hand back what they were given and never think about the building again. The concern is narrower and more practical. You usually cannot prove that every copy of a key came back. Keys get duplicated at hardware stores and kiosks without any record, and a worker may have made a spare years ago for convenience. When a key was never tracked, the honest answer to the question of who can open the door is that you do not know.
For a business in Broward or Palm Beach County, where many small offices, shops, clinics and warehouses share plazas and multi-tenant buildings, the stakes include inventory, cash handling areas, customer files, tools and vehicles. A rekey is one of the more affordable ways to turn an unknown into a known, and the decision should be made on purpose rather than by habit.
This page is about the thinking and the preparation. It does not describe how locks are defeated, and a technician will not teach that to a caller. What follows is what an owner can do, what to have written down, and what a locksmith will want to confirm before work begins. For the broader idea of why access control belongs in your routine, see after-hours business access planning.
Start with an inventory of what was actually issued
Before calling anyone, write down what the departing employee had. Many owners skip this step and then rekey doors that did not need it while overlooking one that did. A good inventory covers more than the front door key.
Think through the full list of access points a person might have been given: the main entrance, a back or loading door, a storage room, a manager's office, a cash drawer or safe, a file cabinet, a company vehicle, a gate remote or fob, an alarm keypad number, a lockbox on the premises, a mailbox or parcel key, and any shared online or door-controller credentials. If your building is managed by a landlord, ask whether the employee was also given a building key, a parking tag or a suite fob.
- Door keys: which doors, and whether the key was stamped Do Not Duplicate
- Electronic credentials: fobs, cards, keypad numbers, app-based locks
- Alarm system numbers and any remote arming apps
- Vehicle keys, fobs and gate or lot remotes
- Cabinets, safes, cash boxes and inventory cages
- Keys held for a neighboring tenant or the landlord
Check your own records before assuming the worst
If you keep a key log, this is the moment it earns its place. A log can be as simple as a page that lists the key stamp number, the date it was issued, the person who received it and a signature. If a worker signed for two keys and returned two, the question is mostly settled, though the possibility of unrecorded copies remains.
If you never kept a log, do not panic. Start one now. Write down every key you currently know about and where it is. Then decide how much risk the unknown copies represent for the doors in question. A key to a break room is a different problem from a key to the room where cash and customer records are kept.
Also look at the nature of the departure. A retirement with a handshake and a returned key ring is different from a sudden dismissal, a dispute or a situation where the person still has a reason to be near the property. You are not required to assume bad intent, and a locksmith will not ask you to justify your decision. But you are entitled to be more careful where the risk is higher, and a measured response is usually easier to live with than regret.
Who is allowed to authorize the work
A reputable locksmith will want to know that the person requesting a rekey has the right to ask for it. For a business, that normally means an owner, an officer, a manager with documented authority, or a property manager acting for the owner. If you lease your space, remember that your landlord may control the building-standard locks, especially on exterior doors, so the lease should be checked before any cylinder is changed.
Expect to be asked for something that connects you to the premises. That might be a business license on the wall, a lease, a utility bill in the company name, a state business registration or a photo ID that matches the owner of record. It is not personal; it protects the business from a stranger posing as the owner and asking for its locks to be changed.
Do not let an employee who is staying authorize a rekey of a door that the departing person also used unless the owner has agreed. If a remaining staff member calls and the owner is not reachable, a locksmith may reasonably decline to proceed until the owner confirms. This is the same authorization-first approach described in the guide on locksmith authorization for businesses.
If the dispute involves co-owners, partners or a family business, expect the technician to want written agreement from the people with authority. That slows things for a short time and avoids a much larger problem later.
Rekey, replace or add access control: choosing the right response
There are three broad responses, and each fits a different situation. Rekeying changes the internal pinning of existing cylinders so old keys no longer work and new keys do. The hardware stays in place, the finish matches and the door looks unchanged. It is often the fastest way to cut off old keys when the locks themselves are sound.
Replacement makes sense when the hardware is worn, damaged, poorly matched to the door or out of date for the way your business now operates. A cylinder that sticks, a latch that does not hold or a lock that has been forced is a candidate for replacement rather than rekeying. The article on rekey versus replacing locks walks through that choice in more detail.
Access control, meaning keypads, cards or fobs with a controller, changes the question altogether. With a controller, removing a departing employee can be as simple as deactivating their credential, and you gain a record of who entered and when. It is not right for every small shop, and it has its own maintenance needs, but for a growing team it can end the cycle of rekeying after every departure. Read more at keypad and access control basics.
A technician can only recommend after seeing the doors. For anything beyond a simple single-cylinder rekey, expect an on-site visit before a firm quote. Quotes are given by phone for straightforward work, and complicated jobs are assessed in person.
Which doors to prioritize
Not every door is equal. A practical order of priority puts the highest-value or highest-risk areas first. Cash handling rooms, server or records rooms, inventory storage, owner offices and any door that protects people after hours deserve attention before a staff restroom or a supply closet.
Exterior doors usually come next because they are the first line of defense. If you have both a front entrance and a rear or loading door, remember that the rear door is often the weaker link because it sees less foot traffic and is less visible. In plazas and industrial parks around Fort Lauderdale, Pompano Beach and West Palm Beach, rear service doors face alleys or loading docks where no one is watching, so they matter.
Interior doors can often wait unless the departing employee had unique access to them. If budget or time limits what you can do at once, a locksmith can help you sequence the work, rekeying the most critical doors immediately and scheduling the rest. A written list of priorities, door by door, makes the phone conversation faster and the quote more accurate.
Keys, fobs and alarm numbers beyond the lock cylinder
Rekeying the cylinder does not touch the other ways a person might get in. If the building has an alarm, change the numbers or user entries that the employee knew. If the alarm company holds a user list, ask them to remove the person. If you use a smart lock or an app, remove the user and revoke any shared links.
Fobs and cards are issued to a person but work on a reader. If your reader system lets you disable a single credential, do that right away. If it does not, you may be rekeying only half of the problem. Ask the vendor how credentials are managed, and keep a short note in the key log about the date each was disabled.
Do not forget non-door keys. A company van, a trailer, a storage cage, a tool crib or a gate remote can be as costly to lose control of as the front door. Vehicle key questions are a separate area; for company vehicles the guide on company car or fleet lockouts may help you think about who should hold what.
What the technician will check when they arrive
A technician starting a rekey for a business will usually begin by confirming who you are and that you may authorize the work. Next comes a walk of the doors on your list. The technician checks the type of cylinder, whether the hardware is standard or a more specialized style, how many keys are needed and whether any doors are keyed alike or part of a master system.
If the building is part of a master key system, the situation changes. A rekey on one door can affect the master hierarchy, and some doors may belong to the landlord or property manager rather than to you. The technician may ask who holds the master key and may decline to alter a door that is not under your control. That is the correct behavior, not an obstacle.
The technician will also inspect the condition of the hardware. A loose cylinder, a worn latch, a door that does not close squarely or a strike plate that does not line up can undermine even a freshly rekeyed lock. If the hardware is a concern, you will be told, and any recommendation to replace rather than rekey should come with an explanation you can understand.
Before work starts, you should hear how the service call charge works and what the likely scope is. Ask about the process for your specific doors and make sure the quote you were given by phone still applies once the technician has looked at the hardware.
Controlling the new keys so you do not repeat the problem
A rekey is only as good as what you do afterward. If new keys are handed out casually, the next departure will leave you in the same position. Treat the new key set as something that needs a system.
Consider a restricted keyway, where blanks are controlled by the manufacturer and copies require authorization, as a way to make unauthorized duplication harder. The page on restricted keyways and key control explains how those systems work in general terms. Combine that with a simple log: key stamp, who holds it, date issued, date returned.
Limit the number of keys. Each additional key is another thing to track. If someone needs access only during certain hours, a keypad with individual numbers or a fob can be a better fit than a metal key that cannot be turned off.
Write down a short offboarding checklist that includes keys, fobs, alarm numbers, vehicle keys and any building credentials, and use it every time. A checklist does not take long and removes the need to remember what was issued to whom.
Putting it together and calling for help
A sensible sequence looks like this. First, build your inventory of what the departing person held. Second, decide which doors carry real risk. Third, confirm who can authorize the work and gather a document or two that connects that person to the business. Fourth, check your lease or building rules for doors you do not control. Fifth, call a locksmith, describe the doors, explain the situation in plain terms and ask how the quote and service call charge work.
If the departure involved a threat, a theft or anything that makes you feel unsafe, contact the police first and let a locksmith follow. For a life-threatening situation, call 911 before anything else. After a break-in, the page on security after a business break-in covers the recovery steps.
When you are ready, call and talk the situation through. A good dispatcher will ask about the doors, the type of business, the lock types you know about and who will meet the technician, then explain what is possible and what needs an on-site look. Call when you are ready to describe the job.
Questions people ask
Do I have to rekey every time an employee leaves?
No. Rekeying is a judgment call based on risk. If a worker returned every key you issued, left on good terms and had access only to low-risk areas, you may decide to keep the locks as they are. If they held keys to cash, records or inventory, or you are unsure that all copies came back, rekeying the sensitive doors is a reasonable step. A locksmith can help you decide, but the decision belongs to the owner.
Can a manager authorize the rekey instead of the owner?
Sometimes. A locksmith generally wants to confirm that the person asking has authority over the premises. A manager with documented authority or a property manager acting for the owner may qualify. If there is any doubt, expect the technician to ask for the owner's confirmation or for paperwork showing who controls the space. This protects the business from improper requests.
What if my landlord controls the exterior door locks?
In many leased spaces, the landlord or building manager owns the exterior and common-area hardware. Changing it without permission can breach your lease. Check your lease, then ask the landlord to approve or perform the change. A locksmith will usually decline to alter a door you cannot show you control. Interior doors within your suite are more often yours to manage.
Will a rekey stop a former employee's fob or alarm number from working?
No. Rekeying only affects the key-operated cylinder. Fobs, cards, keypad numbers, app credentials and alarm entries are managed in their own systems. Disable or change each one separately through the vendor or alarm company, and note the date in your records so you have a complete picture of what changed.
How do I get a quote for a business rekey?
Quotes are given only by phone. For a simple rekey of a few standard cylinders, a dispatcher can often give guidance from your description. More complicated work, such as master key systems, specialized hardware or many doors, needs an on-site visit first. There is a service call charge, and it is explained on the phone before anyone is dispatched.
What should I have ready when I call?
Have the business name and address, the number and type of doors involved, a note of which keys or credentials the departing employee held, and something that shows you can authorize the work, such as a lease, registration or photo ID. Knowing whether doors belong to a landlord and whether a master key system exists will make the conversation much quicker.
Describe the situation by phone and we will tell you what the job involves. Quotes are given by phone. Jobs that cannot be quoted without seeing them need a technician on site, and the service call charge is explained on the phone before anyone is dispatched.
