Lockmaster

If you’ve never replaced a lock before, it can be tricky to know where to begin! Use the steps below to gather the key details you’ll need to order the correct replacement lock.

1

Check for a Manufacturer’s Name

Great - you've found Lockmaster stamped on the faceplate, or, the centre case of the lock looks like one below. If you're unsure, you can always send us an image here.

2

Identify the Locking Points

Look up and down the faceplate to see what locking mechanisms are fitted in addition to the latch and deadbolt. Example Answer: 2 Hooks and 2 Rollers

3

Measure the Backset (Measurement A)

The backset is the distance from the front edge of the faceplate to the centre of the keyhole (cylinder).

4

Measure the PZ / Centres (Measurement B)

This is the distance from the centre of the keyhole to the centre of the square spindle hole (where the handle goes through).
