Frequently Asked Questions — Northwest London
-
How much does a lock change cost in Northwest London?
From £89 for a standard Yale-type cylinder up to £189 for BS3621 mortice locks. Anti-snap upgrades add £30 to £60. Quoted on the call before arrival.
-
How quickly can you change locks in NW postcodes?
Same day in most cases. Booked before noon usually means done by late afternoon. Edwardian semis in Camden or Kilburn with rare lock types sometimes need 24 hours if the cylinder isn't a standard size.
-
Do you fit insurance-approved locks?
Yes, BS3621 deadlocks and SS312 Diamond cylinders are stock items. Mention your insurer's spec when booking.
-
Should I change all the locks or just one?
Depends why. Lost keys means everything keyed alike across the property. Moving in or post-tenant, 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 breaks off if attacked, leaving the working part intact. Worth fitting on NW postcode terraces and semis with the older flush-fit cylinder type.
-
Can you keep my existing keys working?
Swapping cylinders means new keys, usually three per lock. If you want everything keyed alike, say so on the call. Slight extra cost but useful across multiple doors.
-
Do you take old locks away?
Yes, recycled unless you want to keep them. Some people do for backup or outbuilding spares. Just ask.
Have a different question? Just call.

-
Burglary attempt on our place in Brent. Frame splintered, door jamb cracked, but they didn't get inside. Engineer boarded the door overnight then fitted BS3621 deadlocks the next morning.
-
After a break-in near Barnet, the police gave us a number for an insurance-approved locksmith. Same engineer did the overnight boarding and came back to fit anti-snap cylinders the next afternoon.
-
Conservatory door multipoint had been catching for months. Finally died altogether. Heavy-duty replacement now in place, closes solidly for the first time in ages.
-
Lost my keys on the Jubilee Line. Locksmith picked the lock on my Edwardian semi without damaging the original mortice. Fair price for inner-London.
