If the locking mechanism on a multipoint is not functioning it might be that you can replace the centre case gearbox instead of installing a full locking system. The centre case has the mechanics of multipoint locks that is the link to the rest of the lock. We offer a wide range of top brand centre case gear boxes including Fullex, Mila, ERA Products and Lockmaster, and installing these parts is definitely user-friendly but please note that it is important to lubricate the gearbox before installation. The multipoint locks are operated by lifting the handle to engage the locking points at the same time as you are turning the key to deadlock your door.
