Can a Landlord Change the Locks? A Guide for Tenants and Landlords

The short answer is that a tenant has the right to change the locks during a tenancy — but should inform the landlord and, in most cases, provide a copy of the new key. A landlord does not have the right to change the locks while a valid tenancy is in place, even if rent is in arrears. Doing so is classed as illegal eviction under the Protection from Eviction Act 1977, which carries serious legal consequences. The only lawful way for a landlord to regain possession of a property is through the courts.

Between tenancies — once a tenant has formally vacated and handed back the keys — the situation changes entirely. At that point the property is empty and the landlord has every right to arrange a door lock replacement in Bexleyheath before the next occupant moves in. This is not just a legal nicety; it is simply good practice. No landlord can be certain how many copies of the old keys are in circulation, and fitting fresh cylinders or locks gives the incoming tenant genuine peace of mind from day one.

A key handover at the end of a tenancy might look tidy on paper, but keys are easily copied. A previous tenant, their friends, a former partner, or even a tradesperson who held a set during the tenancy could still have access. For landlords operating in Bexleyheath and the surrounding DA6 and DA7 areas, a straightforward lock change between lettings is one of the most cost-effective steps you can take to protect both the property and your incoming tenants.

For tenants moving into a new flat or house, it is entirely reasonable to ask the landlord or letting agent to confirm that the locks have been changed since the last occupancy. If they cannot confirm this, you may wish to arrange the change yourself — with the landlord's knowledge — and provide them with a spare key as required under most tenancy agreements. Our team at Bexleyheath Locksmith can carry out the work quickly and neatly, leaving you with a full set of keys and a lock that meets current insurance standards.

These four terms get used interchangeably, but they mean different things, and knowing the distinction helps you ask for exactly the right job. A lock replacement means swapping out a worn, damaged, or old lock mechanism for a new one of the same type — for example, replacing a tired euro cylinder on a uPVC door with a fresh anti-snap, TS007 3-star rated cylinder. A lock installation means fitting a lock where none previously existed, adding a 5-lever mortice deadlock to a rear door that only had a nightlatch, for instance. A lock change, in the residential context, usually refers specifically to fitting new cylinders or mechanisms after a tenancy ends so that old keys no longer work. Repair covers faults: a stiff lock, a misaligned keep, a broken lever inside the mechanism — problems where the hardware can be fixed rather than replaced.

Understanding which category your situation falls into matters because it affects the parts needed, the time involved, and the right approach. When you call 020 3757 5689, our team will ask a few straightforward questions about your door type and what has happened, then confirm an exact up-front price before anyone travels out to you — the final quote reflects the lock or cylinder type required, the time of day, and travel distance to your address.

Bexleyheath Locksmith carries out door lock replacement Bexleyheath for all common residential door and lock types. Here is what that covers in practice, so you know exactly what to ask for. Mortice lock replacements (deadlocks and sash locks): The 5-lever mortice deadlock is the workhorse of British front doors. Insurers frequently require a BS3621-stamped lock on the main entrance, particularly on older terraced and semi-detached houses common throughout Bexleyheath and Welling. We replace worn or broken mortice deadlocks with BS3621-compliant equivalents and can also replace mortice sash locks — the combined latch-and-deadlock found on many internal and back doors. Euro cylinder lock replacements: uPVC and composite doors — the type fitted to most properties built or refurbished in the last 25 years — use a euro cylinder inside a multipoint locking system. Cylinder snapping is a known vulnerability and a genuine concern in the DA6 and DA7 postcode districts. We fit anti-snap, anti-pick, anti-drill cylinders rated to TS007 3-star, which satisfy most home insurance requirements and represent a meaningful security upgrade over standard cylinders. Night latch and rim cylinder replacements (Yale-style): The Yale-type nightlatch remains one of the most common locks on London front doors, including those throughout the Bexleyheath area. We replace rim cylinders and the full latch body where needed, upgrading to double-cylinder versions where appropriate for added security.

A routine lock change at the end of a tenancy is usually a calm, planned job. The outgoing tenant vacates and returns all keys, the landlord or letting agent contacts us, and we attend at a convenient time to fit new cylinders or locks. For a typical front door in Bexleyheath — a uPVC door with a euro cylinder multipoint lock and sometimes a rim nightlatch above it — the whole job can be completed in well under an hour. We test every lock and mechanism before we leave, hand over the full set of new keys, and can advise on whether the existing hardware meets current insurer requirements. Emergency situations are different. If a tenant has been locked out in Bexleyheath because a lock has failed, a key has broken in the cylinder, or there has been an attempted break-in, that is when our 24 hour locksmith Bexleyheath service comes into its own. We send a locksmith straight away and are usually with you in around 30 minutes. We will always verify that the person requesting entry has the right to be there — this is standard practice and protects everyone involved. If you find yourself locked out, check first whether a window is on the latch or whether a neighbour holds a spare key; if not, call us on 020 3757 5689 and we will get you back inside without damage to the door wherever possible. For landlords, an emergency lock change may be needed after a reported break-in or after a difficult tenancy ends — if, for example, a tenant has left without returning all keys or a dispute has arisen. We can attend at short notice, assess the door and lock condition, and fit appropriate replacement hardware the same visit. The call-out charge and any parts required are confirmed with you before work begins, so there are no surprises on the invoice.

For landlords: make a lock change part of your standard check-out procedure, alongside the inventory and deposit return. It costs relatively little and removes a genuine risk. If the property has a uPVC front door, ask specifically about anti-snap euro cylinders — standard cylinders fitted during the original build are often well below current security standards and may affect your insurance position. If your property is in a block of flats, check whether you are responsible only for the flat front door or also for the communal entrance lock. For tenants: read your tenancy agreement before changing any lock. Most agreements require you to inform the landlord and provide a spare key; failing to do so can be treated as a breach of contract even though you are legally entitled to change the lock. If you are moving into a property and the landlord cannot confirm the locks have been changed since the previous occupant, that is a reasonable conversation to have with your letting agent before you sign. If you are ever concerned that a landlord or third party has changed your locks without your knowledge while your tenancy is still active, that is a matter for your local council's housing enforcement team and potentially the police — it is a criminal offence under English law. Keep records of your tenancy agreement, any correspondence about lock changes, and all key receipts.
