No wrecking yards?
I would recommend trying to take the locks complete with electric switch (testing is easy).
Easier than swapping the cylinder is swapping the end T-piece using a small punch.
The other way around, you have to make sure the little electric switches work.
Btw, unlike locks, the r & l switches are the same and swap either way.
When swapping cylinders, they can easily come apart with lots of little pieces (used large clear plastic zip loc).
I paid one of the yard regulars to grab the key when fresh cars with key were added.
In my experience, its not easy to get the late W201 door lock cylinders out without damaging the (surprisingly fragile) cast metal T piece at the end, unless they can be manipulated with the key during removal.
Earlier W201 locks have a shorter T piece.
Got a pic post in the W201
