Lock Change & Replacement

Replacing a lock outright — rather than simply having a spare key cut — is the only way to be certain that no unauthorised copy is in circulation. This matters most at the point of a property changing hands: when a landlord re-lets a flat, when a sale completes, or when a relationship breaks down and someone has moved out. It also matters when a lock has been in service for many years, shows signs of wear, or is a basic euro cylinder without anti-snap protection. In Rainham, as across the rest of outer east London, burglars have been known to exploit cylinder snapping on uPVC and composite front doors — a technique where the visible part of the cylinder is broken off to access the cam inside. Upgrading to a TS007 3-star anti-snap cylinder, or a cylinder bearing the British Standard kitemark, closes that vulnerability entirely.

For doors fitted with traditional timber frames, the most common arrangement is a Yale-type nightlatch combined with a 5-lever mortice deadlock. Many home insurance policies in the UK specify that the mortice deadlock must meet BS3621 — a standard worth checking with your insurer before you decide on replacement hardware. Our technicians can supply and fit BS3621-rated locks and will confirm the rating of any part they install, giving you the documentation you may need for your policy.

A door lock change Rainham residents request most often falls into one of three categories: euro cylinder replacement on uPVC and composite doors, nightlatch replacement on timber front doors, and 5-lever mortice deadlock replacement on the same. Multipoint locking mechanisms — the type where a single handle lifts several hooks or bolts along the door edge — are common on uPVC patio doors and French doors leading to gardens, and these can be replaced or repaired without taking the door off its hinges. We also deal with communal entrance locks in blocks of flats, where a landlord or managing agent may need several flats' doors changed in a single visit.

The process is damage-free wherever the door and frame allow. Our technician will assess the existing lock, confirm the correct replacement size and specification with you, carry out the swap, and test the new lock through several full cycles before handing over the new keys. If the door has suffered any damage — a forced entry, a snapped cylinder, or a broken uPVC mechanism — we will explain what repair or additional work is needed and quote for it separately before touching anything.

An emergency lock change in Rainham is one of the most common calls we receive in the evenings, at weekends, and on bank holidays. A broken key in the barrel, a snapped cylinder that leaves a door impossible to lock securely, or a situation where a property has been entered without permission — all of these make it unsafe to leave the door as it is overnight. When you call 020 3725 7665, we send a locksmith straight away and are usually with you in about 30 minutes, wherever you are in the RM13 area. We answer every call, every hour of the day.

Landlords and letting agents in Rainham have particular responsibilities around lock changes. A landlord cannot legally change the locks on a tenancy without following the proper legal process, and equally a tenant cannot withhold access by fitting an unauthorised lock. Our team is experienced in both situations: we can carry out a lawful lock change for a landlord between tenancies, and we can also help a tenant who has been locked out or whose lock has failed through no fault of their own. If there is any doubt about authorisation, we ask for proof of ownership or a letter from the managing agent before carrying out any work — this protects everyone involved. If you need guidance on the legal position, the relevant starting point is the housing law advice available from Havering Council, which covers the RM13 area.

Door lock replacement Rainham homeowners and landlords choose from us is always specified with the door type and insurance requirements in mind. For a standard timber front door, that typically means a BS3621 5-lever mortice deadlock and a good-quality nightlatch. For a uPVC or composite door, it means a TS007 3-star anti-snap euro cylinder in the correct length for the door — a cylinder that is too long presents a snapping risk even if it carries a kitemark, so accurate measurement matters. We carry cylinders in a range of sizes and finishes and can usually match the existing hardware so the door looks consistent.

Our fully insured technicians carry professional-grade tools and work to a standard that leaves the door functioning correctly and the frame undamaged. Because we are a mobile service, we come to your home, your rental property, or your workplace in Rainham rather than asking you to travel anywhere. If you are unsure which lock specification your insurer requires, call us on 020 3725 7665 and we can talk through the options before you commit to anything — there is no obligation to book.

We do not use fixed published rates because the cost of a lock change depends on a number of honest variables: the type of lock and the specific hardware required, whether the job is straightforward or involves a damaged door or frame, the time of day — evenings, weekends and bank holidays carry a different rate from weekday daytime — and the distance our technician is travelling within the Rainham area. What we do commit to is transparency: we confirm an exact price on the phone before anyone sets off, and that price does not change when the work is done, provided the job is as described. There are no hidden call-out charges that appear only on the invoice. If the technician arrives and finds additional work is needed that was not apparent over the phone, they will quote separately for it and wait for your agreement before proceeding.
