Lock change cost in Milton Keynes?

From £89 for a basic euro cylinder up to £189 for an insurance-grade anti-snap multipoint cylinder. Anti-snap upgrades on the standard MK uPVC doors are typically £119 to £149 fitted. Quoted before we leave the depot.

Same-day across MK postcodes?

Almost always yes. Booked before noon, done by late afternoon. The standardised uPVC doors across the MK grid squares mean we carry the right cylinders on the van for nearly every house.

Will the new locks meet my insurer's spec?

If your policy specifies a kitemarked anti-snap cylinder, that's what we fit on uPVC doors by default. SS312 Diamond cylinders are stocked. Mention the policy wording when booking and we'll match it.

Should I change every lock or just one?

Lost keys means changing every external lock that key opens. Moving into a new MK estate house, the front and back uPVC doors usually cover it. After a burglary, every external multipoint cylinder.

Anti-snap cylinders on uPVC doors, worth it?

Yes, particularly on early-2000s grid-square estates. Standard cylinders fitted at build are easy to snap. Thames Valley Police data flags lock-snapping in parts of MK6 and MK15. Anti-snap leaves the working portion intact even if attacked.

All doors keyed alike on one key?

Yes. Tell us at booking and we'll cylinder all your external doors so a single key works everywhere. Slightly more expensive than mixed cylinders but easier on a keyring.

Old cylinders taken away?

Yes, unless you ask to keep them. Some folk hold onto old cylinders for outbuildings or sheds. Just tell the engineer at the start.

What Our Customers Say

Came back from a weekend in Bedford to find the back door forced. Frame splintered. Boarded that night, BS3621 set fitted Sunday morning before the insurer's deadline.

Rachel P. Burglary repair
Replaced every lock after buying a 1990s estate house in Furzton. All on multipoint uPVC doors, anti-snap cylinders fitted to all three. Two hours done.

Helen V. Lock change
Locked out at 5am with a flight from Luton. Engineer reached our MK4 home in 19 minutes, opened the uPVC door non-destructively, no callout charge. Caught the flight.

Emma L. Emergency lockout
Half a key broken deep inside the front door cylinder. Other locksmiths I rang said they'd have to drill. This one extracted both halves and saved me a cylinder. Forty quid.
