Frequently Asked Questions — North London
-
How much does a lock change cost in North London?
From £89 for a standard Yale-type cylinder up to £189 for BS3621 mortice locks. Anti-snap upgrades add £30 to £60 depending on brand. Quoted on the call before we arrive.
-
How quickly can you change locks in N postcodes?
Same day in most cases. Booked before noon usually means done by late afternoon. Older Victorian properties in Islington or Hackney with rare lock types sometimes need a 24-hour turnaround if the cylinder isn't a standard size.
-
Do you fit insurance-approved locks?
Yes, BS3621 deadlocks and SS312 Diamond cylinders are stock items on the van. If your insurer specified a particular brand, mention it on the call.
-
Should I change all the locks or just one?
Depends on why. Lost keys means everything keyed alike across the property. Moving in or post-tenant, just front and back is usually enough. Post-burglary, every external door and window lock should be considered.
-
What is anti-snap and do I need it?
Anti-snap cylinders have a sacrificial section that snaps off if attacked, leaving the working part intact and the door secure. Worth fitting on N postcode terraces where the original cylinder is the older flush-fit type.
-
Can you keep my existing keys working?
Swapping cylinders means new keys, usually three per lock. If you want everything keyed alike (one key opens everything), say so when booking. Slight extra cost but useful across multiple doors.
-
Do you take old locks away?
Yes, old cylinders are recycled unless you want to keep them. Some people do for backup. Just ask.
Have a different question? Just call.

Property in N15 with a forced entry from a side gate. Engineer fitted full BS3621 deadlocks plus a new euro cylinder on the back door. Insurance accepted the receipt without quibbles.
-
Attempted break-in on our Edwardian semi off Green Lanes. Frame was splintered but the deadlock held. Engineer boarded it overnight then fitted BS3621 mortice locks the next morning for the insurance claim.
-
uPVC back door in Stoke Newington wouldn't lock after the kids slammed it one too many times. Multipoint gearbox had finally given up. Booked Tuesday morning, sorted before lunch. £89.

Back door wouldn't lift to lock. Worn keep, dropped hinges, the lot. Engineer diagnosed it inside five minutes and fixed everything in one visit.
