Your Local Locksmith in Guildford
Guildford is a historic county town with everything from Victorian and Edwardian terraces near the centre to newer developments out across the GU postcodes. We're the lock specialists local homeowners and landlords call when they want the job done properly — a local locksmith, never a national call centre.
Older Guildford homes often have timber doors that need a BS3621 mortice deadlock for insurance, while newer builds run uPVC and composite doors that benefit from a 3-star anti-snap upgrade.

Which Lock Does Your Home Need?
Most UK home insurers set a minimum lock standard. Here's what they ask for — and what we fit as standard.
5-Lever Mortice Deadlock
Timber doorsThe British-Standard deadlock most insurers require on wooden front and back doors — kitemarked, and pick- and drill-resistant.
Anti-Snap Euro Cylinder
uPVC & composite doorsA 3-star kitemarked cylinder resists lock snapping — the most common way these doors are forced. The single most worthwhile uPVC upgrade.
Locking Mechanism
uPVC & composite doorsThe strip of hooks and bolts down the door edge. When the handle stiffens or the door won't lock, it's usually the gearbox — repaired or replaced.
Not sure what your policy needs? We'll check your doors and tell you straight — the right lock for your insurance, with no upsell.
Common uPVC Door Problems We Fix
uPVC and composite doors fail in a handful of predictable ways. We carry the parts to put most of them right in a single visit.
You have to lift the handle hard to lock
Usually a worn or failing multipoint gearbox. We replace the gearbox so the door locks smoothly again — no need for a whole new door.
The door won't lock or catches on the frame
Often a dropped or misaligned door. We realign the door, hinges and keeps — frequently with no new parts at all.
The key turns but the lock doesn't engage
A failed cylinder cam or worn mechanism. We replace the faulty part and can upgrade you to a 3-star anti-snap cylinder at the same time.
A key has snapped in the lock
A worn key or seizing cylinder. We extract the broken key and repair or replace the cylinder, getting you back in without damaging the door.
The handle feels loose or wobbly
A worn handle or loosened fixings. We replace the handle and spindle and re-secure the mechanism.
The door is draughty or won't seal
A compression or alignment issue. We adjust the keeps, hinges and compression so the door pulls in tight and locks securely.

Lock Change Guildford — FAQs
How long does a lock change take in Guildford?
Most single-door lock changes take 20–45 minutes. A straightforward euro cylinder swap is quick, while fitting a new BS3621 mortice lock to a timber door can take a little longer. If we’re changing every external lock, we’ll give you a realistic time when we quote.
What lock do I need for my home insurance?
Most UK home insurers ask for a BS3621 5-lever mortice deadlock on timber doors, and a kitemarked anti-snap euro cylinder on uPVC or composite doors. We fit insurance-approved options as standard and can advise on exactly what your policy is likely to require.
Should I change the locks or just rekey them?
Rekeying changes the internal pins so old keys no longer work, which is cheaper and quick. A full lock change replaces the hardware itself and is the better choice if the lock is worn, outdated or below the security standard you want. We’ll recommend whichever genuinely suits your situation.
Do I need to change the locks when I move into a Guildford home?
It’s sensible. You rarely know how many copies of the old keys are out there with previous owners, tradespeople or letting agents. Changing or rekeying the external locks gives you a clean start so only you hold working keys.
What is an anti-snap cylinder and do I need one?
Anti-snap (3-star, TS007) cylinders are engineered to resist lock snapping, the most common way uPVC doors are forced. If your door has an older standard cylinder, upgrading to anti-snap is one of the most worthwhile security improvements you can make.
Do you supply the locks or do I buy them?
We supply and fit the locks. We carry basic, medium and high-security options on the van, so you can choose the right tier on the day and we fit it there and then at the fixed price agreed before we start.
Are you a local locksmith or a national chain?
We’re a local, owner-run Surrey locksmith. You deal directly with the person fitting your locks in Guildford — not a national booking line that passes the job on.
Is the work guaranteed?
Yes. Our workmanship is backed by a 12-month guarantee, and the locks themselves carry their manufacturer warranty.
Can you fit smart or keyless locks?
Yes. We supply, fit and set up keypad and smart locks alongside traditional British-Standard ones, and can advise which suits your door and household.
