Multipoint UPVC Door Lock Gearbox Only Centre Case 35mm Backset Twin

My old uPVC gearbox gave up the ghost and would only lock/unlock with real difficulty. Finally, it wouldn't lock at all, which was a real security issue. This is a direct replacement for my old gearbox, cost less than half of the price quoted by lock retailers for the part only and took twenty minutes to fit. You MUST take the old one out and measure it so you are sure you get the right item as they come in lots of size variations. Also, search YouTube to see how to fit the gearbox - you don't need to take all of the door edge-strip off. Be sure that the two lugs are located properly before you put all the screws back [you'll need a T20 bit and a Phillips]. Do that and you are sorted, and will have a perfectly-locking door, and will have saved c£200 over calling out a locksmith.

Perfectly fits, perfectly working. Seems durable, but time will tell that.

Did the job as expected

Straight replacement, easy to fit and works as it should

This is a good replacement - there is a die cast part inside it that had snapped on my old lock which meant the key wouldnt lock the door. I took apart the door strip with the mechanism and took it all apart. Found this lock and it is an identical replacment and was very easy to replace - took 30 mins. Even with no experience id recommend anyone give it a go.

Great product at a good price

This Safeware gearbox is exactly the same as the one it replaced in everyway. So glad I found it on Amazon and it probably saved me £300 (after looking at the video on how to replace). Dismantling the old one and it is very complicated inside and you wonder how they manage to make a part as obviously well engineered for so little cost. Perfect fit and that includes having to use the original fixing screws. Very satisfied with this!

Great replacement product, fitting was very simple, just unscrew the long mechanism that runs the lengh of the door and remove it from the plastic frame. Then detach the faulty "Gearbox" (... What you have just bought) and replace with the new one. Mine would no longer lift the locking points into place but after replacement and reassembly it all worked fine again. Much cheaper and easier than replacing the whole lot with a Yale or other brand complete unit.
