Which lock do you need?
Tenants moving into a house-share in Willesden, landlords with lets in Camden and Brent and new owners of semis in Hendon and Mill Hill all have good reason to change the locks.
uPVC and composite doors use a euro cylinder. We fit anti-snap cylinders, which resist the snapping attack burglars use on cheap cylinders. Timber front doors usually have a nightlatch and a mortice deadlock; for insurance that deadlock should be BS3621.
Most lock changes in Northwest London take 30 to 45 minutes. Common reasons: moving into a new home, lost or stolen keys, a tenant moving out, or a lock that has become stiff and worn.
Locksmiths who know Northwest London
Period houses in Hampstead and St John's Wood often keep their original timber doors and sash windows, so locks that are decades old are common and worth upgrading to BS3621 when they fail.

Lock change in Northwest London: common questions
How much is a lock change in Northwest London?
From £88 supplied and fitted for a standard euro cylinder. BS3621 mortice deadlocks start from £109. The price the engineer confirms includes the lock and the fitting.
Do I need anti-snap locks?
On a uPVC or composite door, we recommend them. Snapping is the most common way in through those doors, and anti-snap cylinders are built to resist it.
Do you charge a callout fee?
No callout fee when you go ahead with the job. If you decide not to go ahead after the engineer has arrived, a £49 assessment fee covers the visit. Otherwise you pay for the job itself in Northwest London, at the price the engineer confirms with you before starting.
How do I pay?
When the job is finished. Card, cash or bank transfer, and you get a written receipt you can use for an insurance claim.
How quickly can someone get to me?
An engineer is typically with you in 15 to 20 minutes, and within 30 minutes at most. We give you a time on the phone based on where the nearest engineer is right now.
Do nights and weekends cost more?
No. The price is the same at 3am on a Sunday as it is at midday on a Tuesday, bank holidays included.
Do you cover Hampstead, Golders Green, Hendon and Mill Hill as well as Camden?
Yes. The same 24-hour line covers the NW postcode area, including Camden, Primrose Hill, Hampstead, St John's Wood, Kilburn, Cricklewood, Willesden, Hendon, Golders Green and Mill Hill.
Can an older timber front door in Hampstead or St John's Wood be fitted with a modern BS3621 lock?
Usually yes, if the door itself is sound. The engineer looks at the door, says which lock suits it and confirms the price before any work begins.
