A locksmith in Harpenden who confirms the price before starting

Harpenden is a Hertfordshire commuter town beside a large common, with Victorian and Edwardian houses near the centre and newer homes around it. Rothamsted Research, a long-established agricultural research centre, lies on its edge, and our engineers cover the whole town.

Most calls we take in Harpenden are one of three things: someone locked out, a lock that has stopped working, or a household that wants the locks changed after lost keys or a move. You describe the door and the lock, we give you the price, and the nearest engineer drives to you.

Our engineers carry the common cylinder sizes, nightlatches, mortice locks and uPVC gearboxes, so most jobs are finished in one visit.
