I needed to replace the mortise lock on a wooden patio door, so I bought another ERA brand one online hoping it'd fit without much adjustment.

The lock fits just fine but the issue is the plate that covers the lock, and the keep.

The doors have rebates on both edges and overlap, the keep and plate are designed to fit this rebate. I thought I could use the old ones on my new lock but although the lock has the same basic dimensions the layout is subtly different such that the old ones won't fit.

I need to order a set of the bits required and am wondering what they are called to help find them online?

When I had this problem, after a lock began to jam and needed to be
replaced, I just used the new striker plate that came with the new lock,
which meant chiselling out a bit more of the door frame to take the slightly
different placement of the "pockets" for the handle and lock bolts.

I never know whether "mortise" should be spelled "mortice" in the UK.

American spelling of "mortice".

Thanks folks - makes sense that it'd be called "rebate set" with the benefit of hindsight!

As for the spelling of mortice/mortise, again with the benefit of hindsight, I prefer mortice!!

I looked it up. There seems to be no clear afavouritre,. I spell it mortice.

In the past faced with similar issues I have found it simpler to
"modify" the existing striker plate with a Dremel so that the new lock
clears.

Most locks I have had have the bit the lock fits into when closed and they
are never it seems the same as the existing one. So you either unscrew the
old one and put on the new and chisel away the door to fit, or you go
bonkers and modify the old plate.
As for any handles and the key hole I'm surprised these are not all
different too, most of the locks in this house on internal doors are around
1939 vintage and although you can get almost exact replicas from the fitting
in the door standpoint almost all the holes are displaced by about half an
inch, making the job really annoying.

Yes and when it does not fit you are mortise-fied?

The alternative approach is to take some bits out of the new lock and
use that to repair the old one. It obviously depends on what's wrong
with the old one and how much ERA have changed the design internally
over the years.
