As soon as I got home this morning, I turned the ignition off and
removed the remote. I opened the driver's door and the chime went off
and would not time out. I closed the door again and the chime went off.
I got out of the car and tried to lock the doors with the remote. The
doors and tailgate did not lock. Now I can only lock the doors using
the key. Tried my wife's remote and the malfunction persisted. At least
the symptom is repeatable, not intermittent.
Note: The tumbler in the ignition switch was replaced by the dealer in
May of this year due to problems with the locking/alarm system. It took
ONLY seven trips to the dealership to have the problem fixed!
Please help me before I go nuts.
So far nobody has replied to my cry for help. Any ideas regarding my
locking system problem are very much needed and appreciated. The factory
warranty expired this past May 26th.

Thanks, Captain, for your comments. I thought I was crying in the
The locking system is all electric these days. That's why is so tough
to diagnose and fix the malfunctions without the computerized tools that
are available to the dealerships. RATS!
If the key has been removed from the ignition (lights off, etc), there
should be no chime; sounz like a faulty computer module. I've had a few of
those modules go bad on me in my 2000 ml320.
As I recall, I had a problem with the keyless entry remote not locking, I
replaced the remote battery and that did not fix it, then the dealer
reminded me that there is a procedure in the manual for resetting the remote
where you must re-sync it by positioning the ignition switch while
depressing the remote (I forget), check the manual.
I also had a problem where the alarm went off intermittently and only could
be shutoff with the remote. Turned out the computer found it was a bad glass
breakage sensor in the passenger door.

Thanks for your comments. I'll print them and let the service advisor
read them on Monday when I take the ML for service. This would be the
8th time for the same reason! The most recent "fix" of the locking
system lasted for a month and a half.
