Why the end of a lease is a security moment
A lease ending marks a change in who has the right to be in a space. Up to the last day, the tenant and its people may enter. After that, only the landlord and the next occupant should. Yet the keys, the keypad number and the cards do not disappear on their own. Employees may keep a key in a drawer at home, a former manager may remember the entry number, and a vendor may still hold a copy from last year's repair.
For the tenant, the concern is liability and clean closure: you want to show that you returned everything and are no longer responsible for the space. For the landlord, the concern is knowing that old keys no longer work before the next tenant moves in, or before the space is shown to prospects.
In Broward and Palm Beach, commercial turnover is routine. Strip centers, office suites, medical buildings and warehouse units change hands constantly, and the lock handover is usually a small step in a larger move-out. Treating it with care avoids disputes about deposits, break-ins and lost equipment.
Start with the lease
The lease is the first document to read. It normally addresses several lock-related questions: whether the tenant may alter locks during the term, whether the landlord keeps a key, what must be returned at the end, and who pays when locks are changed. Some leases require the tenant to return all keys and cards on or before the last day. Others state that the landlord will rekey at the tenant's expense, and others leave it to the landlord entirely.
Look for sections titled surrender of premises, alterations, access, and security. Notice also any language about holdover periods, because staying a few days past the end date can change what the landlord may do with the locks.
If the lease is silent or unclear, ask the property manager in writing and keep the reply. A short email asking who will rekey and when avoids a conflict on the last day. A locksmith cannot interpret a lease for you, but will ask whether the person requesting a lock change has the authority to do it, and a clear answer from the landlord helps.
Who is responsible for changing the locks
There is no single answer, and anyone who claims otherwise is guessing. In many commercial leases, the landlord is entitled to rekey the space after the tenant leaves and may charge the cost to the tenant, often against a security deposit. In other leases, the tenant must hand the space back with all keys and has no obligation to rekey. Some leases require the tenant to restore the original lock system if it was altered during the term.
A fair way to think about it: whoever is making the change should be the party that has the authority under the lease. A tenant should not rekey a door without landlord approval during the term if the lease forbids it. A landlord should not rekey before the tenant's possession ends unless the lease or a written agreement allows it.
When responsibility is disputed, document the lock status at the move-out walkthrough. Photograph the locks, record how many keys are being returned, and have both sides sign a short list. That list is useful evidence if a disagreement arises later.
| Situation | Usual question | Where the answer lives |
|---|---|---|
| Tenant altered the lock | Must original system be restored? | Alterations clause |
| Landlord wants new keys | Who bears the cost? | Surrender or deposit clause |
| Tenant added electronic access | Must it be removed or left? | Alterations and surrender clauses |
| Keys are missing | Is a rekey required? | Surrender clause and landlord notice |
| Holdover past end date | May landlord change locks? | Holdover and default clauses |
Collecting and counting keys before you leave
As a tenant, start gathering keys well before the last day. Pull out your written key list if you have one. If you do not, create one now by asking each manager and key holder what they carry. Collect keys for every door: front, back, storage, closets, file rooms, mailboxes, and any padlocks on equipment you are leaving behind.
Count what you have, and compare it to what you received at the start of the lease. If the original key list from the landlord exists, use it. If you cannot account for a key, tell the landlord now and say so in writing. A missing key does not have to be a crisis, but hiding it can turn a routine rekey into a dispute.
Do not mail keys without a record. Hand them over at the walkthrough and ask for a signed receipt that lists the number and type. If a mailed return is the only choice, use a trackable method and photograph the keys beforehand.
- Gather keys for every door, closet, mailbox and padlock.
- Compare against the original list you received.
- Report missing keys in writing before the end date.
- Get a signed receipt for keys returned.
Keypads, cards and alarm systems
Mechanical keys are only part of the picture. If your suite has a keypad, change the entry number or hand administration to the landlord, and tell the landlord what the number is on handover. If it uses a card or fob system, ask whether credentials must be returned, deactivated or left in the system. If the system account is yours, transfer it to the landlord or close it according to the lease, and make sure no former employee remains an administrator.
Alarm systems belong in the same conversation. Many are contracted separately by the tenant with an alarm company, and the contract may continue after the lease ends. Tell the alarm company when you are leaving, and make sure that the next occupant is not locked into your account or that your account is not still receiving alarms from a space you no longer control.
If equipment installed by you, such as readers or electric strikes, is to be removed, confirm what the lease requires. Some leases say alterations must be removed and the door restored, while others allow improvements to remain. See keypad and access control basics for how these systems work.
Rekeying at handover: when it makes sense
Rekeying changes the internal pins in a lock so previous keys no longer work, using the same hardware. For a landlord getting ready to show or relet a space, it is usually the most direct way to make sure no old key still works. For a tenant who returns all keys, it is not always necessary, but if any key is missing or there is a concern about unaccounted copies, rekeying removes the doubt.
Rekeying is generally quicker and less disruptive than replacing every lock, though it depends on the condition of the hardware. A technician will check each lock. Worn cylinders, damaged latches or locks that no longer fit the door may need to be replaced instead. Complicated jobs need an on-site visit, and quotes are given only by phone.
Landlords who manage many units often use a consistent system, such as restricted keys or a master system, so rekeying at turnover fits their routine. Read master key systems for businesses and key control for landlords for more on how to plan.
Three common lease-end situations
A retail tenant in a strip center is closing a location. Staff have already left, the manager holds the only full set of keys, and the landlord wants the space back by the end of the month. The practical sequence is to gather keys, count them against the original list, hand them over at a joint walkthrough, and give the landlord the keypad number and alarm company contact. If any key cannot be found, the manager says so in writing, and the landlord decides whether to rekey.
A professional office tenant is moving to a larger suite in the same building. Here the landlord may keep the existing master system, and the departing tenant returns suite keys while the landlord rekeys the old suite for the next occupant. The tenant should confirm that no keys remain with former employees and that any suite-specific electronic access is closed out.
A warehouse tenant is leaving after altering the roll-up and personnel doors with their own padlocks and a keypad. The lease says alterations must be removed. In this case the tenant arranges removal, restores the original hardware where the lease requires it, and returns the original keys, while the landlord inspects the doors at handover. Each case turns on what the lease says, which is why reading it first matters more than any general rule.
The move-out walkthrough and paperwork
A joint walkthrough on or near the last day is the best protection for both sides. Walk the space together, and at each door record the condition: does it lock, does the latch catch, are keys present, is anything damaged? Take dated photographs. Write a short list that both parties sign, covering keys returned, keypad numbers handed over, cards turned in and any lock-related damage.
If the tenant caused damage, such as a cylinder that was drilled or a door that no longer latches, the lease usually explains how repair is handled. Document it neutrally. If damage predates the tenant or came from normal wear, note that too.
Keep a copy of the signed list. The tenant should hold it with the lease and the landlord with the file. Also see locksmith work documentation and receipts if a locksmith performed any work, since a receipt describing what was rekeyed or replaced helps show what condition the locks were left in.
Authorization when a lease is ending
A locksmith will ask who you are before changing any lock, and the end of a lease is a situation where authority can be unclear. A tenant may still have possession up to a certain date, and a landlord may not have the right to change locks until that date or until the lease terminates. A person requesting a rekey must be able to show the right to do so for that space on that date.
Typical documents are a government photo identification, the lease, a letter from the owner or property manager, and for corporate tenants, a company document showing the person's role. If a landlord is acting after a tenant has abandoned the space, the landlord may need documentation of termination. These matters depend on the lease and local law, and a locksmith cannot give legal advice, though they will ask the questions that protect everyone.
If there is a dispute between landlord and tenant over access, a locksmith will not choose sides. They may decline to change locks until the parties confirm authority. This is not an obstacle. It protects both parties from a change that could be challenged later.
Preparing for the next tenant and your final call
Once the old locks are sorted out, landlords can think about the next occupant. This is a good time to check that doors latch properly in South Florida humidity, that strike plates are secure, that hinges have not sagged, and that exit hardware works. Repairs are easier while the space is empty.
Think also about how the next tenant will receive keys. A short written key list delivered at lease signing, with the number of keys and what each opens, prevents confusion later and sets a clean starting point.
When you are ready to arrange lock work at lease end, call and explain who you are, which space is involved and what stage you are at. Have your lease or authorization, photo identification, and a landlord or tenant contact ready. Quotes are given only by phone, and larger jobs need an on-site visit. There is a service call charge, explained before dispatch, and the company does not promise arrival windows. Call to talk through the handover and we will help you plan it.
Questions people ask
Do I have to rekey when my commercial lease ends?
It depends on the lease. Some require the tenant to return keys and leave the rekeying to the landlord, while others assign it to the tenant. If you altered the locks during the term, you may need to restore the original system. Check the surrender and alterations clauses, and ask the property manager in writing if anything is unclear.
What if I cannot find all the keys I was given?
Tell the landlord before the end date and put it in writing. A missing key can usually be handled by rekeying, which is a routine step. Hiding the problem tends to cause disputes about deposits and responsibility. Gather what you can find and get a signed receipt for the keys you return.
Can the landlord change the locks before my lease ends?
Generally the lease and local law control this. In many cases the tenant has the right to possession until the end date, and a landlord cannot simply change locks during the term. A locksmith will ask who is requesting the work and whether they have authority. If there is a dispute, resolve it between the parties first.
What should I do with my keypad or card system at move-out?
Check the lease for whether equipment must be removed or may stay. Change or hand over the keypad number, return or deactivate cards, and transfer or close any system account so former employees are no longer administrators. Tell your alarm company when you are leaving so monitoring and accounts end cleanly.
How much will a lock change cost at lease end?
Pricing is only given by phone, never on a web page. It depends on how many doors, what lock types and the condition of the hardware. Larger jobs need an on-site visit. A service call charge applies for dispatch and is explained on the phone before anyone is sent. Your lease may say who pays.
Will a locksmith take sides in a landlord and tenant dispute?
No. A locksmith checks that the person requesting work has authority and may decline to proceed if that is unclear. They do not decide who is right. If both parties agree in writing, or the proper documents are shown, work can usually go ahead. Settling authority first protects everyone involved.
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.

A handover checklist you can fill in over the final weeks
The final weeks of a commercial lease are busy, and locks are easy to forget. A checklist keeps them from slipping through. Begin by listing every door the tenant controls, including interior rooms, storage areas, rear doors and any gate or roll-up. Next to each, note the lock type, how many keys exist and where each key is. Doing this early gives you time to find missing keys or arrange a rekey. Allow extra time for locks on any shared or landlord-owned doors, since coordinating with another party can take more than one conversation and more than one day.
Add the electronic items to the list: keypad codes, card readers, alarm panels and any cameras tied to door activity. Record who has administrator access and plan to change or transfer it. Remove staff and former employees from systems before handing over. Take photos of each lock and door on the final walkthrough, since they serve as a record of condition for both sides. Remember to deactivate cards and codes for departed staff early, and write down what you removed and when, so there is a clean record at the end.
Share the checklist with the landlord or property manager so expectations are clear. If the lease says the tenant must return the premises with locks working, test each one and arrange any repair before the final day. If the lease allows the landlord to rekey, confirm that and coordinate. Ownership or authority is checked before opening anything, and the scope and any quote are explained before work begins. Call us to confirm availability and bring your lease details. Keep the checklist and photos after the lease ends, because a dispute months later about the condition of the doors is much easier to settle with a clear record.
