Multipoint Gearboxes

The gearbox is the centre case of a multipoint lock, behind the handle and cylinder. If the handle is floppy, the key won't turn, or the door won't lock, the gearbox is often the only part that has failed and can be replaced without changing the whole lock.

We stock genuine and copy gearboxes for Fullex (including Crimebeater, SL16 and XL), ERA, Fuhr, Avantis, Yale Asgard, Cego Surelock, Mila and ABT Gibbons Monalock systems, including passive gearboxes for double doors. Check the brand, backset, centres and faceplate size on your existing gearbox.

Buy it, and we can fit it. We are not just an online shop: our own locksmith engineers can install what you order, so you get the right product and a proper installation from one company. Fitting is available across England from £70.80 per hour including VAT (£59 + VAT) on weekdays, and £82.80 including VAT (£69 + VAT) from 5pm, at weekends and on bank holidays. Just tick I require installation on the product page when you add it to your basket, or call 0333 305 2967.

Frequently asked questions

Genuine or copy gearbox?

A genuine gearbox is made by the lock's maker. A copy fits the same system and costs less. Both are listed with the system they suit.

Can I change a gearbox myself?

It is possible with the door open, but the strip must be removed from the door edge. If the door is stuck locked, call a locksmith.

Can you fit it for me?

Yes. Our locksmith engineers can supply and fit replacement multipoint gearboxes, including on doors stuck shut. Tick "I require installation" when you order, or call 0333 305 2967. Fitting is available across England from £70.80 per hour including VAT (£59 + VAT) on weekdays, and £82.80 including VAT (£69 + VAT) from 5pm, at weekends and on bank holidays.
