How much does a new lock fitted cost in Manchester?

A standard new Euro cylinder fitted typically runs £80–£180. A British Standard BS3621 mortice or rim lock fitted runs £120–£250. An anti-snap, anti-bump high-security cylinder (insurance-recommended for uPVC and composite doors) usually £140–£250. The variation is the cylinder you choose; labour is similar.

Should I rekey or replace?

Rekey is cheaper but only worth it on quality cylinders that are otherwise in good condition. If your current lock is old, worn, not anti-snap, or doesn't meet your insurance requirements, replacing makes more sense than rekeying. We'll give you a straight answer when we see it.

What does British Standard BS3621 actually mean?

BS3621 is the British Standard for thief-resistant locks for entry doors. It's the spec home insurers usually require on final exit doors (front and back). It covers things like deadlock requirements, key cycles, drill resistance and saw resistance. Most insurance policies expect BS3621 on every external door; without it, a claim after a break-in can be refused.

Are anti-snap cylinders worth the extra cost?

On a uPVC or composite door, yes — without question. Lock snapping is the most common way burglars get into uPVC doors in the UK, and a standard cylinder can be snapped in under 30 seconds. Anti-snap (3-star Sold Secure Diamond, or Kitemark TS007 3-star) defeats the technique. The extra £20–£40 on the cylinder is the cheapest security upgrade you can make.

Lock replacement that does the job once

There are a hundred reasons to need new locks. Moving into a place where you don't know who has keys. Cleaner or builder finished a job. Tenant moved out. Insurance wants British Standard on the front door. Or you've just realised the cheap uPVC cylinder the builder fitted in 2003 can be snapped by a teenager in under a minute.

We do lock replacement and upgrades across Manchester with the locks your door actually needs, not whatever's loose on the van, and we fit them so they meet the standard your home insurance expects. Fixed prices, clean work, and a proper job the first time.

The locks we fit

Depending on your door, the right answer is one of:

Euro profile cylinders for uPVC and composite doors (most modern external doors). The cylinder is the small barrel where the key goes; it's the bit that matters for security. Quality varies wildly here.
Mortice locks for traditional wooden doors — 2-lever for internal doors, 5-lever BS3621 deadlocks for external.
Rim cylinder nightlatches (Yale-style) for second locks on wooden doors.
Multipoint mechanisms for uPVC and composite doors — the mechanism that runs the full length of the door with hooks and bolts. Replacement is different from cylinder replacement and is covered on our uPVC door repair page.

For nearly every external door in Manchester, the right modern fit is either a 3-star anti-snap Euro cylinder (on uPVC/composite) or a BS3621 5-lever mortice (on wood). Anything less and you're not meeting standard home insurance terms.

British Standard BS3621 — why your insurance asks for it

Most home insurance policies in the UK require BS3621 locks on all final exit doors. It's a thief-resistance standard covering drill resistance, pick resistance, key combinations and bolt strength. Without BS3621 on the door, a claim after a break-in can be refused — and we've had customers find that out the hard way.

If you've moved into a place and you're not sure what's fitted, we can tell you in five minutes. If it doesn't meet standard, replacing the lock is far cheaper than the deductible on a refused claim.

Anti-snap cylinders — the single best upgrade

The most common way burglars get into uPVC and composite doors in Manchester (and across the UK) is lock snapping. They use mole grips or a snap-bar tool to break the cylinder at its weak point, exposing the cam, and turn the lock in seconds.

A standard cylinder snaps in under 30 seconds. A proper 3-star anti-snap cylinder (Sold Secure Diamond, or BS Kitemark TS007 3-star) doesn't — the cylinder is hardened, scored to break on the outside instead of the inside, and includes anti-pick and anti-drill protection. The cost difference is £20–£40 on the cylinder. It's the cheapest meaningful security upgrade you can make on a uPVC door.

If you live in an older terrace with the original builder's cylinder still in place, especially in areas like Salford or Old Trafford, upgrading to anti-snap is the first thing we'd recommend.

Rekey or replace?

A common question. The honest answer:

Rekey (just changing the pins so a different key works) only makes sense on a quality cylinder in good condition that you want to keep. It's faster and cheaper, but you keep whatever security level you had.
Replace when the lock is old, worn, doesn't meet British Standard, isn't anti-snap (on uPVC), or has been damaged. Replacement gets you a clean, current spec.

Most calls we get for "I've moved in, change the locks" end up as replacement because the existing cylinders are old or non-compliant. We'll always tell you which is the better value when we see the door.

When new locks are urgent

A few situations where you shouldn't wait:

After any burglary or attempted break-in — the locks need replacing immediately, not just rekeying.
After losing a key set you can't account for.
Moving into a new property, especially a let where you don't know how many key copies exist.
A tenant moves out and you don't have all the keys back.
Cylinder is sticking, worn, or showing signs of attempted tampering.

For any of those, you want it done today, not "this week". We work across Manchester city centre, Didsbury, Withington and the rest of the metro and can usually fit a same-day appointment.
