When should I change my locks in Cambridge?

After moving in, losing keys, ending a tenancy, splitting up, or after any student turnover where keys may be unaccounted for. Original Victorian mortices in CB1 and CB2 also benefit from a refresh.

Do you fit BS3621 insurance-grade locks?

Yes. BS3621 five-lever mortice deadlocks for wooden doors, and TS007 three-star anti-snap cylinders for uPVC and composite. Both meet major insurer requirements.

Can you keep the original brass on a Mill Road terrace?

Yes. We swap the internal mechanism while reusing the original plates and escutcheons. The door looks identical from outside.

Typical lock change cost?

Single euro cylinder swap from £89. Full BS3621 mortice on a wooden door £119 to £159. Multi-lock packages for student lets quoted on inspection.

Are anti-snap cylinders worth fitting?

On any uPVC or composite door, yes. Snapping is the most common forced-entry method. A three-star Sold Secure Diamond cylinder takes far longer to defeat than a budget unit.

Multiple locks keyed alike?

Yes. Front, back, garage and bedroom locks can be keyed alike at the time of fit. Useful in shared student houses where one master key is preferred.

How long does a lock change take?

Cylinder swap is 20 to 30 minutes. A new mortice fit on a wooden door is closer to 45.
