Why locks need a plan during a buildout
A suite buildout is one of the busiest periods in the life of a commercial space. In the course of a few weeks, people from many trades need to get in: demolition crews, electricians, plumbers, drywall teams, painters, flooring installers, low-voltage and alarm vendors, and inspectors from the city or county. Each of them needs access at different times, and many arrive before the tenant has moved a single desk.
If nobody plans for that, the usual result is a pile of duplicate keys handed around informally, a lockbox with a number that everyone knows, and a door that cannot be traced to anyone once equipment starts moving in. By the time the business opens, the number of people with a way in may be much larger than the tenant realizes.
The goal is simple. Give each person the access they need for as long as they need it, keep a record, and finish the project with the tenant in control of the suite. A bit of coordination at the start between tenant, landlord and general contractor makes that possible, and it costs far less in aggravation than sorting out unknown keys later.
Who controls what: tenant, landlord and contractor
Start by sorting out whose door is whose. In most commercial leases, the landlord controls the building entrance, common areas, stairwells, mechanical rooms and often the building master key system. The tenant controls the suite itself once possession is delivered, although the lease may require the tenant to keep the landlord's lock system or to give the landlord a key for emergencies.
The contractor is neither. They are a guest of the tenant, working under the tenant's contract, and their access should be limited to what the job requires. The tenant should not assume the contractor can change locks, order a new keying system or give copies to subcontractors without approval.
Read the lease and the construction rules or tenant handbook if one exists. Some buildings require that all lock work be done by an approved vendor so the landlord's master key system stays intact. Others permit the tenant's own locksmith as long as keys are provided to the landlord. If you are unsure, ask the property manager before ordering anything.
- Landlord: building doors, common areas, master system, emergency access.
- Tenant: suite doors once possession is delivered, subject to the lease.
- Contractor: temporary access under the tenant's direction.
- Everyone: no lock changes without written approval from the right party.
Landlord master keys and what they mean for the tenant
Many multi-tenant buildings use a master key system. The landlord or property manager holds a key that opens every suite, while each tenant has a key that opens only their own space. This is common in office parks, medical buildings and shopping centers. It lets the landlord respond to leaks, alarms and emergencies without waiting for a tenant to arrive.
For a tenant, that means somebody other than you can open your suite. Ask who holds the master key, how its use is recorded, and under what circumstances the landlord enters. Leases normally address this. If your business handles sensitive records, cash or medications, talk to the landlord about how entry is controlled and whether the tenant must be notified.
If you want to change the suite lock yourself, check whether your new lock must fit the building system. Replacing a lock with one that does not fit the master may be prohibited. In other buildings, the tenant may install a separate lock and give the landlord a key. Either way, the decision belongs in writing before any hardware is changed. See master key systems for businesses for how these systems are structured.
Limiting contractor access without slowing the job
Contractors need to work efficiently, and chasing the tenant for a key every morning slows them down. The answer is not to hand out copies casually but to set up a controlled arrangement. Common options include a construction core, a temporary lock that the contractor controls during the buildout and that is replaced with the tenant's permanent lock before move-in, or a lockbox whose combination is changed after the project.
A construction core is a removable cylinder used during building. Keys given to the contractor open the suite, and at the end of the project the core is swapped out, so every construction key stops working at once. It works well when many trades are involved because it avoids leaving unknown keys behind. Ask whether your building and locksmith support this approach.
Whatever method is used, name one person on the contractor's side as responsible for keys, usually the superintendent. They sign for what they receive and are responsible for returning it. Individual trade workers do not receive keys or copies. If a subcontractor needs to work after hours, the superintendent arranges access.
- Agree in writing who holds keys during construction.
- Choose a temporary system such as a removable core or a controlled lockbox.
- Name one responsible person on the contractor side.
- Record every key issued and when it is returned.
- Replace the temporary system with the permanent one before move-in.
Timing the permanent lock change
The permanent suite locks should go in after the heavy work and before the tenant moves in equipment, inventory or records. Too early, and construction dust, drilling and rework can damage new hardware. Too late, and valuable items are sitting behind a lock that dozens of people could open.
A sensible timeline is to keep temporary access during construction, schedule the final inspection, then rekey or replace the cylinders in a single visit once the contractor has finished. That visit should include all suite doors, storage rooms, server closets and any interior doors that need keying. Collect the temporary keys and confirm against the log.
If the lease requires the landlord to approve final keying, schedule that approval before the visit. Having the property manager present or sending written confirmation prevents a second trip. Quotes are given only by phone, and a multi-door visit usually requires an on-site look so the technician can plan the hardware. A service call charge applies and is explained before dispatch.
Doors, frames and hardware to review during buildout
A buildout is the easiest moment to fix door problems, because walls are open and trades are on site. Look at each door. Does it close and latch cleanly? Is the frame solid? Are hinges secure? Does the lock suit the use of the room, such as an office, a storage room or a cash room? Some interior doors may need a classroom or storeroom function, while others should be simple passage sets.
Pay attention to exit hardware. Doors on exit routes must allow people to leave without a key or extra effort, and the requirements are set by local building and fire authorities. Do not change the function of an exit door without checking those rules. A locksmith can explain hardware options, and the architect or permit office decides what is required.
South Florida humidity matters in new buildouts too. Doors made of wood or hollow metal may swell after painting or during wet months, and a latch that fits in dry conditions can bind later. Ask the contractor to confirm door clearances and give the lock time to settle. See door frame and jamb problems in humid climates for common issues.
Common buildout lock problems and how they start
A few patterns show up again and again in new suites. The first is the unlabeled key ring: a bundle handed over at lease signing with no note about which key fits which door, and no indication of how many copies exist. Ask the landlord for a written list of keys delivered and what each opens, and keep that list with the lease.
The second is the door that was reused. Tenants often keep an existing storefront or suite door to save time, and the lock inside it belonged to the previous occupant. Unless it was rekeyed, former staff of that business may still hold working keys. Rekeying before move-in closes that gap, and it is a routine request for a technician.
The third is the mismatch between plans and reality. An architect draws a card reader on a door, the door supplier ships a standard slab, and the access vendor arrives to find nothing prepared for a strike or wiring. Sharing the hardware schedule with every vendor early avoids rework, and the locksmith can review it for compatibility.
The fourth is forgotten rooms. Server closets, storage rooms, file rooms and janitor closets are often left on construction keys or no lock at all because attention goes to the front door. Walk every door in the suite, including ones nobody plans to use daily, and decide who should be able to open each.
- Ask for a written list of keys delivered at lease signing.
- Rekey any reused door before move-in.
- Share the hardware schedule with every vendor early.
- Check closets, storage and server rooms, not just the front door.
Electronic access, alarms and low-voltage vendors
Many new tenants want card readers, keypads or alarm systems installed during the buildout. This brings in more vendors: low-voltage cabling, access control installers and alarm companies. Coordination between them and the locksmith avoids conflicts, such as a door that was cut for a strike but never ordered with the right latch.
Decide early who administers the electronic system and who owns the account. The tenant should own it, with at least two named administrators. If the landlord's building system controls the entrance, find out how the suite system interacts with it. Read the overview of keypads and access control before choosing.
Change any default numbers or passwords set during installation, and do not leave installer accounts active after handover. Keep a mechanical override key in a controlled place in case power or software fails.
Authorization during a tenant project
A locksmith will ask who you are before touching any suite lock. For a tenant, typical proof is a signed lease or commencement letter, a government photo identification and a business document linking you to the lease. For a contractor acting on the tenant's behalf, written authorization from the tenant is usually requested. For a property manager, a management agreement or company identification may be used.
These checks apply even when the work is routine. They protect the tenant from someone claiming to represent them, and protect the landlord from unauthorized changes to the building. If the lease requires landlord approval for lock changes, expect the locksmith to ask whether that approval exists.
For general guidance on documents, read locksmith authorization for businesses. It lists what is typically accepted and why the check helps you.
Handover checklist and what to do when you call
Before the project closes, walk through a short handover. Confirm that every temporary key has been returned or deactivated. Confirm that permanent keys are in the tenant's hands and that the landlord has what the lease requires. Update your written key list, and change any shared numbers used during construction. Confirm exit doors work from the inside without a key.
When you call to schedule lock work for a buildout, explain what stage you are at, how many doors are involved, whether a master system exists, and who you are in relation to the space. Have your lease or authorization ready, along with photo identification and a landlord contact if approval is needed. Quotes are given only by phone, and larger projects need an on-site visit. There is a service call charge explained on the phone before dispatch, and the company does not promise arrival windows. Call to talk through your timeline and we will help you plan the lock side of the move-in.
Questions people ask
Can my contractor change the locks on my new suite?
Only if you authorize it and the lease allows it. Many leases require landlord approval, and some buildings insist on an approved vendor so the master system stays intact. The contractor should not issue copies to subcontractors without your direction. Put lock responsibilities in writing at the start of the project to avoid confusion.
What is a construction core?
It is a removable lock cylinder used during building. Contractors receive construction keys, and at the end of the project the core is replaced with the permanent one so all construction keys stop working at once. It is useful when many trades need access. Ask whether your building and locksmith can support it for your doors.
Does the landlord have a key to my suite?
Often yes, especially in multi-tenant buildings with a master key system. The lease usually explains when the landlord may enter. If you want to change the suite lock, check the lease first, since some require the new lock to fit the building system or require you to give the landlord a key. Get any approval in writing.
When should permanent locks be installed during a buildout?
After the heavy construction is done and before you move in equipment, records or inventory. Installing too early risks damage from dust and rework, and installing too late leaves valuables behind a lock many workers could open. Schedule one visit to rekey all suite doors, and collect temporary keys at the same time.
How much does it cost to rekey a whole suite?
Pricing is only given by phone, never on a web page. It depends on the number of doors, the type of locks and whether the system must match the landlord's master. A larger project usually needs an on-site visit first. A service call charge applies for dispatch and is explained on the phone before anyone is sent.
Who should own the access control account?
The tenant business should own it, with at least two named administrators so one departure does not cause a lockout. Avoid accounts under an installer's or a former employee's personal email. Change default numbers and passwords after installation, and keep a mechanical override key in a controlled place in case of power or software failure.
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.

Sorting out who owns which door before a buildout begins
A tenant buildout often changes the locks several times, and confusion is common because several parties have a say. The landlord may control the building shell, the entrance doors and a master key. The tenant controls the suite interior. The general contractor needs keys during construction. Before a locksmith touches anything, it helps to write down who owns each door and who may approve changes. The lease usually explains this, so bring a copy or ask your property manager what it says. Ownership or authority is checked before any lock work begins, and unclear authority is the most common reason a visit is delayed.
A practical approach is to separate the project into phases. During construction, temporary construction cores or a contractor key arrangement can keep the site accessible without handing out the final keys. When the work nears completion, the permanent cylinders are installed and the construction keys are retired, so that anyone who had access during the buildout no longer does. A technician can explain how the transition works with your hardware, and the scope and any quote are explained before work begins. Skipping that step means workers may keep keys that still open your finished space.
Coordinate the schedule with the building so that the lock work does not collide with other trades. Doors that are being painted, fitted with new frames or connected to access control need to be finished before final hardware is installed, or the new lock may be scratched or misaligned. Keep a simple log of every key issued and returned during the project, and name one person on your team who approves changes. After move-in, confirm the landlord has the key information they need while you retain control of your own suite.
