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

In England, a landlord does not have the automatic right to change the locks on a tenanted property whenever they choose. Under the Protection from Eviction Act 1977, changing the locks to prevent a tenant accessing their home — without a court order — is illegal. This applies even if rent is overdue, the tenancy agreement has expired, or there has been a dispute. Doing so is classed as illegal eviction, a criminal offence that can result in prosecution and significant civil liability. The only lawful route to recovering possession of a property is through the courts. If you are a landlord in Dagenham and you are unsure where the law stands in your specific situation, Citizens Advice or a housing solicitor can advise you before you act.

Tenants, on the other hand, are generally permitted to change the locks during their tenancy — but it depends on what the tenancy agreement says. Many agreements require the tenant to seek written permission from the landlord or letting agent first, and to provide a copy of the new key. If your agreement is silent on the matter, you are still advised to inform your landlord in writing, particularly if you live in a managed block of flats where a master key system might be in use. What is never acceptable from a landlord's side is a unilateral lock change while the property is occupied and let. The only legitimate moment for a landlord to change the lock without tenant consent is after the tenancy has fully ended and the tenant has vacated — and even then, it is best practice to do so promptly and professionally.

When a tenancy ends — whether through notice, mutual agreement, or the expiry of a fixed term — changing the locks is not just sensible, it is recommended by most letting agents and housing associations as standard practice. You simply cannot know how many copies of the original key were made over the course of the tenancy, and a fresh cylinder costs far less than the consequences of an unauthorised entry. For landlords and agents in Dagenham, our team can carry out a door lock replacement Dagenham tenants have just vacated quickly and cleanly, usually on the same day you need it done.

In practical terms, a lock change on a typical Dagenham property will cover the front door, and sometimes the back door as well. Most front doors in this area are fitted with a Yale-type nightlatch and a 5-lever mortice deadlock — the type insurers commonly require to meet BS3621 standards. Newer build flats and houses with uPVC or composite doors use a multipoint locking system operated by a euro cylinder. Each type requires a different approach. A trained locksmith will assess what is fitted, recommend a replacement that meets or exceeds the existing security rating, and fit it correctly so that the door operates smoothly. If the previous cylinder was a standard one, upgrading to a TS007 3-star anti-snap cylinder at the same time is worth considering — euro cylinders on uPVC doors are a known target for the snap attack method used by opportunist burglars, and Dagenham, like much of outer east London, is not immune to this.

Not every lock issue at the end or start of a tenancy requires a full lock change. Sometimes a uPVC door lock repair Dagenham landlords or tenants need is simply a matter of a worn or stiff multipoint mechanism, a misaligned keep plate, or a euro cylinder that is turning roughly. A skilled locksmith can diagnose the difference on site. If the cylinder alone is the concern — say, because keys were not returned — just the cylinder can be swapped out without replacing the entire multipoint mechanism, which keeps the job straightforward and avoids unnecessary work.

However, if a lock has been damaged — perhaps through a forced entry attempt, prolonged wear, or a failed key break — a full door lock replacement Dagenham is the right call. Trying to repair a compromised lock is rarely worthwhile when a new, higher-specification cylinder or mechanism can be fitted at comparable cost and will give the property proper protection from day one of a new tenancy. Our team carries a range of replacement cylinders and hardware suited to the mix of door types you find across Dagenham — from the older timber doors on the Becontree Estate to the modern composite doors on newer developments near the A13.

Electronic and combination locks are increasingly common on HMOs (houses in multiple occupation) and managed blocks, where a landlord or housing association wants to control communal door access without cutting dozens of keys. If your property uses a digital lock, the question of how to change the code on a door lock becomes directly relevant at every tenancy change. The process varies by manufacturer — if you are wondering how to change the code on a Honeywell door lock, for example, the steps differ from a standard keypad deadlock, and getting it wrong can lock the mechanism entirely. How do I change the code on my door lock is one of the most searched questions we see from both landlords and tenants, and the honest answer is: consult the manufacturer's manual first, and if you are unsure, call a professional rather than risk jamming the lock. Resetting a code incorrectly on how to change the door lock code models that use rolling encryption can require a full mechanism replacement.

For combination padlocks occasionally used on outbuildings or meter cupboards within a rented property, how to change the code on a combination lock is usually covered in the product documentation and is a simple dial-and-press process. But for any lock that secures the main dwelling — whether it uses a keyway or a keypad — a professional locksmith is the right person to manage changes at tenancy boundaries. This protects both parties and ensures the new code or new cylinder is properly set and documented.

Before calling out any locksmith during a tenancy dispute, a brief note on safety and legality: if you are a tenant who has been locked out by a landlord who has changed the locks without a court order, do not attempt to force entry yourself. Document the situation, contact the local council's housing team, and seek legal advice — this is a serious matter and there are protections in place for you.
