Fitting this Lockmaster centre lock case

Remove the Lockmaster Multipoint (lock strip) lock from the door by first removing the handles, the lock barrel and the screws that hold the strip to the side of the door. With the Lockmaster lock strip removed, remove the centre case screws that hold the Lockmaster gearbox onto the locking strip, swap the gearbox, and put the whole locking system back in the door. Simple 20 min job using a screw driver.

This Lockmaster case will replace the gearboxes the current type Lockmaster upvc door locks and. Although the Lockmaster multipoint locks have different widths and different locking points, they use exactly the same gearbox to operate the mechanism. To identify which make of lock you have, look on the locking strip when the door is open, it should have the makers name on it.
