As a family-owned business, we work without call-out fees and offer continuous 24-hour support for household, commercial and vehicle-related lock issues. Our status as the sole Master Locksmiths Association approved firm in Darlington demonstrates our adherence to the highest industry standards. Our fully stocked mobile unit allows us to complete nearly all work on the first visit, from repairing multi-point UPVC and composite door mechanisms to replacing standard locks, window locks and garage door locks. We also maintain consistently competitive pricing by reviewing our rates against other local providers.
Our emergency response service aims to reach customers within an hour whenever possible, ensuring rapid resolution of urgent lock problems. We further enhance property security by supplying and installing accredited anti-snap cylinders designed to counteract lock-snapping attacks. For motorists, we provide full auto locksmith support, including non-destructive entry, cutting spare keys, programming remotes and attending to broken or lost keys. Every part we supply carries a 12-month warranty, and we remain dedicated to customer satisfaction, efficiency and clear professional guidance across all aspects of our work.

Rang early saturday morning about 8am after finding my car had been accessed and spare key taken, by 9am my keys were recoded. Mark travelled to my vehicle and worked quickly and efficiently. A really nice guy, he really did save the day because the thief came back later that day to try and steal my car. Cost me a heck of a lot less than replacing my car.
