Following on from my earlier thread I've hopefully got a mate sending me
some 1.2mm thick cutoff discs for my angle grinder soon so I can cut through
the jammed mortice. After that am I likely to be able to find an identical
sized lock to replace this 25 y/o one of unknown origin or is more carpentry
likely to be needed? I have no idea if locks have some sort of standardised
range of sizes or if every manufacturer does their own thing.

It would be ideal to get one that just slots straight back into the same
hole in the door.

It's probably a standard size. What brand is it?

It will be a "standard" size - but there are *lots* of standards - so you
need to measure all the dimensions - length, width, offsets, etc. and find
another one the same.

Does yours look anything like this?

If I could get it out I could maybe tell you but at present "unknown origin"
is my best guess.

It's that kind of thing yes. Mortice at the bottom, latch at the top. My key
has only 3 prongs on it though and I've just had a measure and it's exactly
45mm from the edge of the door to the centre of the keyhole. So it's looking
like a standard 67mm lock then? Every dimension will be the same in a new
lock?

OK, best to take it to the shop when you do finally get it out and
compare directly with potential replacements. If it is a well known
brand, you should consider starting with that brand.

If you want to upgrade to a higher spec., e.g. Chubb BS3621 Insurance
Approved, then you should be aware that Chubb do the 3K74 and the 3U74,
which are notionally identical apart from the fact that the 3U74 case is
sized to replace "standard" Union/Yale locks and copies thereof.

I'm fortunate in having a large speciality lock shop quite near. When I
replace locks I always take the old one there & so far they have always been
able to supply an exact match.

IME Often the new lock is a standard-ish size but the box staple (?)
(the bit the bolt locks into) isn't.

That's a good start, but there are other dimensions which might vary - like
the vertical distance between keyhole and latch. They're all shown in the
link posted by 'Geo'.

I think the strike side will almost certainly need opening up, the
deadbolt width increased a bit with the 2004 revision of BS3621 so
things had to move to accommodate it. At least the strike side is the
easier one to modify. The strike box will be deeper to take the longer
throw too.
