How quickly can a locksmith reach me in Derry/Londonderry?

If the keys could be traced to your address — lost with ID, a tagged keyring, or stolen — yes, change every cylinder those keys opened. If they were dropped somewhere with nothing identifying and weren't stolen, the risk is low and you can weigh it up.Is it cheaper to re-key or replace a lock?
For modern euro-cylinders it's almost always cheaper to replace the cylinder than re-pin it. For older mortice locks, re-keying can be economical. A locksmith confirms which applies once they see the lock.How much does it cost to change the locks after losing keys?
Around £80–£130 for a single external door and £140–£220 for a front and back door, fitted with anti-snap cylinders and key sets. A window-lock check adds £50–£90.What if the lost key opened more than one door?
Every cylinder that key could open should be changed — front, back, side and garage as applicable. Tell the locksmith what the key opened so the full job is priced before any work begins.Will my insurer want anything for a lock change?
If you're claiming, they'll want an itemised invoice and proof the new locks meet British Standard (BS 3621 or TS007). Every completed LockSafe job generates that PDF automatically.
