Lock Repair
A lock that refuses to turn, a handle that won't lift, or a mechanism grinding against itself is more than an inconvenience — in a neighbourhood like Finsbury Park, where Victorian terraces, purpose-built blocks of flats and converted houses sit side by side, a faulty lock can mean a genuinely unsecured front door overnight. Finsbury Park Locksmith is a 24/7 mobile service covering the N4 and N7 postcode districts and the surrounding streets, from the flats along Seven Sisters Road to the period terraces off Stroud Green Road. We come to you, assess the problem on the spot, and carry out lock repair wherever possible before recommending a replacement.
Open 24 hours, 7 days a week · Fully insured
Our trained, insured technicians work on all the lock types you are likely to find on a London door: 5-lever mortice deadlocks, Yale-type nightlatches, multipoint locking systems on uPVC and composite doors, rim locks, cam locks, lever locks and more. Whether the fault is a worn internal component, a seized mechanism, a damaged cylinder or a misaligned keep, we aim to restore the lock to full working order without causing unnecessary damage to your door or frame. When repair is not the right answer, we will tell you plainly and confirm an exact up-front quote before any further work begins.

Frequently asked questions
How do I know whether my lock needs repairing or replacing?
A technician can usually make this call within a few minutes of examining the lock. If the core mechanism — the levers, the bolt, the gearbox — is worn but structurally intact, repair is typically the right answer and is often more cost-effective than full replacement. If the lock has been forced, has seized beyond recovery, or is an older model with no available replacement parts, a new lock may be the only option. We will always explain our reasoning and confirm a price before doing anything.
What factors affect the cost of lock repair?
The price depends on several things: the type of lock (a multipoint uPVC gearbox repair differs significantly in complexity from a standard mortice lever service), whether parts are needed and which parts, the time of day the call is made — evenings, weekends and bank holidays are reflected in the call-out charge — and how far our nearest available technician is from your address. We confirm an exact price on the phone before anyone travels to you, so there are no surprises when we arrive.
My key snapped inside the lock — can you remove it without replacing the whole lock?
In most cases, yes. Extracting a broken key from a cylinder or mortice lock is a standard repair task. Once the key fragment is removed, we test the lock with a working key and assess whether the cylinder or internal mechanism has been damaged in the process. If it has, we will explain what is needed. If the lock is otherwise sound, that may be all that is required. Do not try to push or pull the key fragment yourself — it can wedge it further into the barrel.
Can you repair a lock on a uPVC door where the handle has dropped and won't lift?
Yes, and this is one of the most frequent calls we receive. A handle that drops or will not lift on a uPVC door usually means the gearbox inside the door edge has worn or failed. In many cases the gearbox can be replaced without removing the door or the full lock strip, restoring normal operation the same visit. If the euro cylinder has also been damaged — for example if someone has tried to gain entry by snapping or drilling it — we will address that at the same time and discuss fitting an anti-snap replacement cylinder.
I'm a tenant and my landlord is uncontactable — can you still carry out the repair?
We can carry out emergency lock repair for tenants, but we do require some verification of your right to be on the premises before work begins. A tenancy agreement, a utility bill in your name at that address, or any official correspondence showing you live there is usually sufficient. If your property is managed by a letting agent or housing association, trying to reach them first is worthwhile — they may have a duty maintenance line. If you cannot reach anyone and the situation is urgent, call us on 020 7871 7826 and we will talk through the options with you.
Do you work on communal entrance doors in blocks of flats?
Yes. We regularly work on communal entrance doors across Finsbury Park and the wider London area — rim locks, deadlocks, electromagnetic release mechanisms, and door closers that are preventing a lock from functioning correctly all fall within our scope. For work on a shared entrance, it helps to have the permission of your managing agent or the freeholder if possible, particularly for anything beyond emergency repair. If you manage or own a block and need a planned maintenance visit, we can accommodate that too — just call 020 7871 7826 to discuss what is needed.
