Hi again,

(1987 300E)

Having some trouble with the door locks. Haven't really diagnosed yet
but I suspect it's a vaccum issue.

I'm also considering putting in an aftermarket keyless entry system.
Is that something I can do instead of fixing the lock situation, or
would it be in addition to fixing the locks?
