Lock Repair
When a key refuses to turn, a mechanism feels like it is grinding through wet sand, or a handle simply will not lift no matter how hard you try, it rarely means the whole door needs replacing — but it does mean the lock needs attention before a small fault becomes a full lockout. Langley Locksmith is a mobile locksmith service based in Slough, and our trained, insured technicians are on the road around the clock, attending homes, flats, and business premises across the SL postcode area every day of the week, including bank holidays.
Open 24 hours, 7 days a week · Fully insured
We work on all common UK door lock types: 5-lever mortice deadlocks, Yale-type nightlatches, uPVC and composite multipoint locks, euro cylinders, rim locks, and more. Where possible we aim for a damage-free repair — opening and restoring the lock without causing unnecessary harm to the door frame or furniture. If a part is beyond saving, we carry a range of quality replacement components on the van so the job can usually be finished in a single visit. If you are dealing with a stiff or jammed lock right now, call us on 01753 251949 and we will get a locksmith to you straight away.

Frequently asked questions
My key turns but the lock does not seem to engage properly — is that a repair or a replacement job?
This symptom usually points to one of a few specific faults: a worn or broken cam inside the lock body, sheared levers on a mortice deadlock, or a stripped follower that the key turns freely in without moving the bolt. In many cases the internal component can be replaced without changing the entire lock — a full lock replacement is only the right answer if the casing itself is damaged or the lock is so old that parts are no longer available. Our technician will diagnose the specific failure on arrival and explain exactly what is needed before any work starts.
The handle on my uPVC door has to be lifted very precisely before the key will turn — what is causing that?
This is one of the most common uPVC door faults we attend in Slough. It usually means the multipoint lock gearbox is wearing out, or one of the shootbolts is not fully retracting and is placing the mechanism under tension. Sometimes it is simply that the door has settled and the keeps are no longer perfectly aligned with the bolts. A diagnosis visit will determine whether the gearbox needs replacing, the door needs adjustment, or both. Left unattended, this fault typically progresses until the handle lifts but does nothing, or the key can no longer be turned at all.
How is the price for a lock repair worked out, and will I know what I am paying before you start?
Yes — we always confirm an exact price before any work begins, and that is the figure you pay at the end. The price depends on several factors: the type of lock involved, the specific fault and whether parts are required, the time of day (evening, weekend, and bank holiday calls are priced differently from standard daytime hours), and travel distance to your address. There is a call-out charge, and we will be clear about that on the phone before anyone leaves. There are no additions or surprises once the job is done.
Can you repair a lock on a communal entrance door in a Slough block of flats, or does that need the managing agent's permission?
For a communal door, we would typically expect instruction from the managing agent, housing association, or a designated keyholder for the block rather than an individual flat tenant, since that door is shared property. If you are a tenant and the communal lock is faulty, the right first step is to contact your letting agent or managing agent. If it is an emergency — the door is stuck open late at night and poses a security risk, for example — we can attend and carry out a temporary repair or secure the door, but we may still need to verify authority before completing permanent work. Call us on 01753 251949 and we can talk through the specific situation.
My euro cylinder looks intact but was targeted in what seemed like a snap attack — do I need a full lock repair or just a cylinder change?
If a cylinder has been subject to a snapping attempt, even one that did not fully succeed, it should be replaced rather than repaired. A partially compromised cylinder can fail internally in ways that are not visible from the outside, and it may no longer provide the resistance it was designed to offer. We carry anti-snap, TS007 3-star rated replacement cylinders on the van, which is the standard insurers and security guidance recommend for uPVC and composite doors. The rest of the multipoint lock mechanism is usually unaffected by a cylinder attack and does not need to be changed at the same time unless it was also damaged.
How quickly can you get to me for an emergency lock repair in Slough?
We send a technician straight away when you call, and we are usually with you in about 30 minutes — though journey time can vary depending on where in the Slough area you are and what traffic is like at the time. We operate 24 hours a day, seven days a week, including bank holidays, so there is no time when we are unavailable. Call 01753 251949 and we will get someone to you as quickly as we can.
