A tenant has moved out, the keys have been returned, and the property is ready for cleaning or viewings. This is the point when a landlord lock change service can make a real difference. Replacing or rekeying the locks between tenancies gives you control of access, protects the next tenant, and removes the worry that old copies may still be out there.
It is a straightforward job when handled at the right time, but there are a few decisions worth making before anyone turns up with tools. The type of door, the condition of the existing hardware, whether keys are missing, and the legal status of the tenancy all affect the right solution.
Why landlords should change locks between tenancies
A returned key is not always the only key. Former tenants may have given copies to family, friends, contractors, dog walkers, or neighbors. They may not even know how many copies were made over the course of a tenancy. If a key was lost months earlier and never reported, that risk follows the property too.
Changing locks between occupants is a practical security measure rather than an accusation against the outgoing tenant. It gives the incoming tenant confidence that their new home is properly secured from day one. It also gives the landlord a clear set of working keys and a chance to deal with worn or unreliable locks before they become an emergency callout.
For a vacant property, new locks can also reduce the chance of unauthorized access during repairs, decorating, or viewings. This matters especially where tradespeople have had temporary access or a key safe has been used regularly.
A landlord lock change service is not an eviction tool
This is the most important distinction to make. A landlord should not change locks to force a tenant out, prevent them from entering their home, or put pressure on them during a dispute. Even if rent is overdue or the relationship has broken down, locking a tenant out without following the proper legal process can create serious problems.
If a tenant is still legally entitled to occupy the property, access must not be restricted by changing the locks. The right route depends on the tenancy agreement and local housing rules, so get proper legal advice if possession is disputed.
A locksmith can change or repair locks, but cannot decide who has the legal right to enter a property. A reputable local locksmith will ask sensible questions where there is any uncertainty and will not assist with an unlawful lockout.
When should locks be changed?
The best time is after the outgoing tenant has fully moved out, returned possession, and handed back their keys. Do it before the new tenant receives keys, rather than waiting until moving day. It keeps the handover simple and avoids leaving a new occupant wondering whether old keys still work.
There are other times when a lock change may be sensible. A landlord may need help after keys have been lost, a break-in or attempted break-in has damaged a lock, or a former occupant has failed to return keys. It can also be worthwhile after a relationship breakdown, a change in property management, or a period when several contractors have had access.
If the existing lock is stiff, loose, difficult to turn, or requires the key to be lifted or pushed before it works, do not ignore it until the property is occupied. Small faults can turn into a tenant lockout or a door that will not secure properly. Sorting it between tenancies is usually less disruptive and often less expensive than an emergency repair.
Change the cylinder or replace the whole lock?
Not every job requires a full lock replacement. On many uPVC, composite, and modern multipoint doors, the cylinder can be changed while the main door mechanism stays in place. This is often the quickest and most cost-effective option when the lock works well and the concern is simply key control.
A full replacement may be the better call when the lock body is worn, damaged, poorly fitted, or no longer provides the level of security you want. Older wooden doors may have rim locks, mortice locks, or both. The right upgrade depends on the door construction, existing hardware, and how the property is used.
There is a trade-off. The cheapest like-for-like replacement may solve an immediate key issue, but it may not address a weak, outdated, or unreliable lock. On the other hand, replacing every part unnecessarily adds cost. A good locksmith should inspect the door, explain what is working and what is not, then give clear options rather than pushing the most expensive choice.
Check the door as well as the lock
A new lock cannot compensate for a badly aligned door. On uPVC and composite doors, handles that feel loose, a door that catches on the frame, or a multipoint mechanism that needs force can all put strain on the cylinder and internal components.
Before changing a lock, the door should be checked for alignment and smooth operation. If the door is dropping or the keeps are out of line, an adjustment may be needed alongside the new cylinder. This helps the lock last longer and makes it easier for tenants to secure the property correctly.
The same applies to patio doors, garage access doors, and windows. A rental property is only as secure as its easiest entry point. You do not necessarily need to replace everything at once, but identifying weak or faulty access points lets you plan repairs before they become urgent.
What to ask for when booking
Give the locksmith a clear picture of the job. Say whether the property is vacant, whether keys are available, and what type of door is involved. If you can describe the problem – for example, a key turns but the door will not open, the handle has become floppy, or keys have not been returned – that helps them arrive prepared.
It is also worth asking whether the quote covers labor, replacement parts, and new keys. If you manage several properties, keep a simple record of when locks were changed, what type was fitted, and how many keys were issued. This makes future maintenance easier and provides a useful handover record.
For vacant homes in Melksham, Trowbridge, Chippenham, Devizes, and nearby areas, using a genuinely local mobile locksmith can be particularly useful when access is needed quickly. You should be able to speak to the person handling the work, get a straightforward explanation, and know what has been fitted before the job is finished.
Avoid key handover confusion
Once the work is complete, decide exactly who receives each key. The new tenant should receive their agreed set, while the landlord or managing agent should retain only the keys they are entitled to hold and store them securely. Avoid leaving spare keys hidden outside the property. It may feel convenient, but it defeats the purpose of changing the locks.
If you use a key safe for contractors or inspections, change its code between tenancies or whenever the code may have been shared too widely. A key safe is useful for planned access, but it needs the same care as the lock itself.
For landlords who want a practical, no-fuss service, GHI Locksmiths can assess the lock, replace or upgrade it where needed, and make sure the door is securing properly before the next handover.
A lock change between tenancies is a small job that protects the property, the next tenant, and your peace of mind. Arrange it early, keep a clear record of the keys, and deal with any stiff or damaged hardware while the property is empty.
