Trouble finding replacement internal door lock

[Joe Woods]

Hello,

I recently decided to replace a lock in an internal door, so I could use the lock again (the current one has no keys!)

I popped the lock out of the door and went down to B&Q + Homebase to try and find a replacement. However, all the ones I saw, and also the websites I've looked at that sell locks don't seem to sell this type. Most the ones for sale are very narrow, and have the handle on top, and lock below. The one I need is a very long lock with the lock on the left, and handle to the right.

I've put some photos of it here:

got any ideas?

Thanks!

Try a locksmith? ;-)

They could probably make up a key to fit the existing lock, if it's not too worn out.

It might be as easy to get a key made up as to find a lock the right size with matching holes.

You're looking for a Horizontal Mortice Sash Lock, which are still be quite common, so a web search should give you a few hits.

Thanks that's great, now I am getting somewhere!

I was considering getting a key made up, but the lock does seem a little old and dirty and stiff, so getting a new lock with keys for £20-£30 would be a good idea. I would imagine a locksmith would want about that amount for dismantling and cleaning, and making up keys.

You could overhaul it yourself very easily; a locksmith will charge about L.7.50 for the first key, and about L.3.00 for copies.

Note that this lock fits your door and furniture - another will most likely not fit at all, so you may end up needing a new door!

The normal mortise lock fitted to an internal door is a simple affair and easy to strip and clean. It's also simple for a locksmith to make a key for - shouldn't be anywhere near the cost of a new decent lock. And this would have the benefit of not having to alter the door for a new lock, especially if it matches others in the house.

Or if you have a similar lock on another door you can compare where the tumblers need to go to get another key to fit it. I shouldn't think it has more than two or three tumblers or whatever they are called. Most likely there are only three or four different keys in the whole range.
