When a tenancy ends and a new one begins, the physical keys involved rarely get fully accounted for. Previous tenants, their guests, cleaners, maintenance contractors, and sometimes even a real estate agent may hold a working key that was never returned. This article looks at why rekeying between tenancies is worth arranging and how it typically works in Dubai.
Why This Gap Exists
Over the course of a tenancy, it is common for more keys to be cut than were originally issued, whether for a partner, a driver, a cleaner, or a family member who stayed for an extended period. When the tenancy ends, there is rarely a reliable way to confirm every one of those keys has been returned or accounted for. A new occupant moving into the same unit has no visibility into any of this unless the locks are rekeyed.
Who Is Usually Responsible for Arranging It
In most cases, the landlord or the property management company arranges rekeying between tenancies, since the locks belong to the property rather than to any individual tenant. That said, an incoming tenant who wants confirmation that this has been done, or who wants to arrange it themselves for peace of mind, is generally within their rights to raise it directly, subject to the terms of their tenancy agreement.
Why Rekeying, Rather Than Full Replacement, Is Usually Sufficient
Unless the lock itself is old, damaged, or being upgraded to a different type such as a smart lock, rekeying is usually all that is needed to ensure no previous key holder has access. It avoids the cost of installing entirely new hardware on a lock that is otherwise working fine, while still fully resolving the actual concern, which is about who holds a working key rather than the lock's physical condition.
Good Timing for This
The most straightforward time to rekey is between tenancies, once the outgoing tenant has vacated and before the incoming tenant moves in, so that keys are only ever cut and issued once the new occupant is confirmed. Arranging it too early, before the previous tenant has fully vacated, or too late, after the new tenant has already moved in, both create unnecessary friction.
What This Looks Like for a Landlord Managing Multiple Units
For landlords or property managers responsible for several units, keeping a simple record of when each unit was last rekeyed, alongside the standard maintenance and handover checklist, makes it easier to confirm this step has not been missed, particularly across a portfolio where tenancies turn over at different times.
What This Looks Like for an Incoming Tenant
If you are moving into a new home and want confirmation that the locks have been rekeyed since the previous tenant left, it is reasonable to ask your landlord or agent directly. If this has not been arranged and you would like it done, our lock rekeying guide covers what the process involves and what to prepare, subject to the appropriate authorisation for the property.
Documenting That It Has Been Done
It is worth keeping a simple written record, even just an email confirmation or a short note, of when a unit was rekeyed and by whom, alongside the standard move-in and move-out paperwork. This is not a legal requirement, and we are not in a position to advise on tenancy law, but as a practical matter it gives both landlord and tenant a clear reference point if the question ever comes up later.
What This Is Not a Substitute For
Rekeying addresses who holds a working key. It does not address a lock that is already old, damaged, or due for an upgrade for other reasons, such as moving to a smart lock for convenience. Those situations are better handled through a full lock change rather than rekeying alone, and it is worth raising both possibilities with your landlord or the technician if the lock itself looks like it may need attention regardless.
Short-Term Rentals Add Their Own Considerations
Properties that change occupants frequently, such as short-term rentals, face this issue more often than a standard annual tenancy. Some owners of such properties choose to rekey between every guest, while others rely on smart locks with per-guest codes specifically to avoid the need for physical rekeying each time. Either approach is reasonable, and the right one depends on how the property is managed day to day.
Commercial Leases Follow a Similar Logic
The same reasoning extends to commercial units changing tenants, a retail shop, an office suite, a warehouse bay, where a previous business's staff, contractors, or cleaners may hold working keys that should not carry over to a new occupant. Commercial handovers typically also involve confirming a trade licence for the incoming business before any rekeying work proceeds.
Raising It Without Assuming the Worst
Asking about rekeying between tenancies is not an accusation against the previous occupant, most people are not attempting anything untoward with a retained key, it simply is not possible to know for certain who still holds one. Framing it as standard good practice, rather than suspicion of anyone specific, tends to make the conversation with a landlord or agent more straightforward.
A Simple Step With a Real Purpose
Rekeying between tenancies is a small, usually inexpensive step that directly addresses a gap most people do not think about until it becomes relevant: the fact that a working key from a previous occupant can remain out there indefinitely unless something is actively done about it.
