How much does a lock change cost in Northampton?

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 arrival.

How quickly can you change locks in NN postcodes?

Same day in most cases. Booked before noon usually means done by late afternoon. Older Victorian terraces 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. If your insurer specified a brand, mention it when you call.

Should I change all the locks or just one?

Depends on why. Lost keys means everything keyed alike. 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 Northampton terraces 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 (one key opens everything), say so on the call. Slight extra cost but useful across multiple doors.

Do you take old locks away?

Yes, old cylinders get recycled unless you want them back. Some people keep them as backup for outbuildings. Just ask.

What Our Customers Say

Changed every lock after my divorce came through. Six locks across the family home, done in under three hours. Quiet about it, no nosy questions.

Naomi F. Lock change
Garage padlock had seized on a 1960s estate in Daventry direction. Quoted £65 over the phone, that's what I paid. New lock fitted within twenty minutes.

Gareth E. Lock change
Tenants in my NN5 property locked themselves out on a Saturday night. Couldn't get to them in time. Locksmith dealt with them directly, sent me the receipt and a photo of the lock.

Oliver J. Emergency lockout
Key snapped clean in the front door before work. Engineer extracted both halves within ten minutes of arriving. Cut a new one on the spot.
