Home / Commercial Locksmith Miami / Commercial Lock Rekeying Miami
Staff changed, a key went missing, or you just took over a new space? Mobile Locksmith Miami rekeys business locks on site throughout Miami, FL, so old keys stop working and only the people you choose can get in. It is part of our commercial locksmith Miami service, built for doors that see far more keyholders than a home ever will.

When a Business Should Rekey
If you cannot say exactly who can open your doors today, it is time to rekey. Common reasons include:
- An employee or manager leaves with a key
- Keys are lost or stolen, or the count no longer adds up
- You move into a space and do not know who kept keys from the last tenant
- A partner exits or ownership changes
Rekeying vs. Replacing a Commercial Lock
Rekeying changes the pins inside the cylinder so a new key operates it and old keys stop working. The lock body and trim stay in place. Replacing means fitting new hardware.
Rekey when the hardware works and the issue is key control. Replace when the lock is worn, damaged, no longer latches reliably, or you want a stronger grade. For the basics of how a rekey works, see lock rekeying Miami.
Offices, Retail Stores and Warehouses
- Offices – suite entries, private offices, file rooms and IT closets
- Retail stores – storefront cylinders, rear delivery doors and stock rooms
- Warehouses – steel man doors and keyed cylinders on loading areas
- Managed properties – tenant suites rekeyed between occupants
Multiple Doors and Master Keys
We can rekey several doors in one visit and key them alike, or keep each door on its own key. Every new key is counted and handed to you.
If your building runs a master key system, the rekey has to fit inside it or the master can stop working, so we check the system before changing pins. If unauthorized copies are a concern, high security locks with restricted keys stop duplicates being cut.
What to Have Ready
- Proof you can authorize the work, such as ownership, a lease or a property manager’s approval

Frequently Asked Questions
How long does it take to rekey a business?
It depends on the number of doors and the type of cylinders. A small office with a few doors is usually a short visit, while larger properties can be done in stages.
Will rekeying work with my existing master key?
Often, yes. If we can read how the existing system is set up, new keys can be cut to fit it. We check this before changing any pins.
Is rekeying enough after a break-in?
Rekeying only changes which keys work. If a lock was forced, bent or drilled, it needs repair or replacement first.
Can you rekey a commercial lock without the original key?
Usually, yes. Some cylinders have to be removed or opened before they can be repinned, which we handle once your authorization is confirmed.
Who can authorize a commercial rekey?
The business owner, an authorized manager, or the property owner or manager. We may ask for ID and a document that connects you to the business or property.
