What sort of lock is this?

ChilliBob

Guys, 

What I thought was our mortice deadlock should be changed, firstly as we've just taken the property on and secondly as only one of the two keys we have works in the door. 

I did some research thinking it'd be straightforward, but then got confused between mortice deadlock and motice sashlock.

I was convinced it was a sashlock but I'm not too sure now. It sits proud on the door not flush. It has a handle on both sides. By the looks of it it's going to need screws from handle on each side removed and two handles either side of the lock, slide out, new one in.. Assuming same size!

But all YouTube videos show these flush, so all you see is the plate, and not the edge like this.

Thoughts much appreciated!

'rebated' is the word you are missing.

It's a sash lock with a rebate kit fitted, similar to:-

Usually used on double doors.

Thank you both, yep, makes sense, we do have double doors. Looks like two and three Lever locks are more common on this sort, unfortunately! Was hoping for 5!

You should be able to remove the screws from the handle from one side (inside probably the easiest). There will be a square steel bar that passes through the hole which should just pull out. Once the bar is removed, undo the two screws holding the lock in place, and it will slide out.

When purchasing a replacement lock, watch out for the distance between the handle/lock and the face (the backset). Not all locks are the same.

Is there a connection between the key operated lock and the door?

There are 5 lever ones available on both Toolstation and Screwfix. You need to check the size, though.

Yeah I have noticed there's a few measurements to consider here. Thanks for that - I'd have taken from both sides! - I might replace the inside knob, it's a little wobbly!

Not sure I follow mate? - There's a normal rim cylinder and night latch, entirely separate to this. Then there's this - a traditional deadbolt key so to speak, and a knob to turn. The knob to turn and they key to unlock this sashlock need to be operated independently. Not sure if that's what you were getting at?

Cheers, I could only see two and three in the rebated variety, many in the flush style. I also saw some rebate kits, which confused me a bit! - But made me wonder if you're supposed to get a rebate kit and a 5 lever for some reason !

rebate kits usually are an additional accessory as pro rata very few are sold - think how many single doors there are for every double door.
