One additional point to keep in mind when troubleshooting the
operation of the door-lock mechanism: there is a small plastic
housing atop the lock cylinder containing the electrical switching
mechanism. The housing can become loose and interfere with proper
electrical operation of the system.
I discovered that fact after I replaced the broken pot-metal gear-arm
on the lock cylinder of my '91 200q. I tested the "arming/disarming"
operation before reattaching the door panel and found that it was
somewhate erratic. Sometimes it worked fine and other times the alarm
"beep" didn't sound. I discovered that the cause of this erratic
behavior was that--as the lock switch was turned--the plastic housing
was stressed and flexed apart; this created some "slack" in the
mechanism which could prevent the switch from making contact. I
reinforced the housing by snugging it up with some turns of wire (or
I may have used a nylon wire-tie, I don't recall the details). This
worked fine for about 3 years. But over the past 6 months, I think
that this little plastic housing has started to loosen again, since
when I lock the car (driver's side) I need to maintain the key
CC-wise for several extra seconds (with some extra force) in order
for the "alarm "beep" to operate. Unlike Dave's situation, I have no
trouble with unlocking, nor getting the other door locks to function
Anyway, it's someting to look out for--next time you're "in there".
