Remote Locking Problem

I don't know if its the key fob or the car..

The alarm siren, "beep" no longer "beeps" when the car gets locked with the key fob.

The remote locking only works close to the car and works only SOMETIMES..

I don't know what the cause or what can I check. its driving me wild!

I might be stating the obvious so disregard this if you have already changed the batteries in the key fob. There is a low battery warning that should come up on the MFD, but I had the same problem on my ML a few years back without ever getting the warning. Changing the batteries solved the issue.

If you have never taken apart an MB keyfob, they can be a pain the first few times. Here is a vid if you need it. By the way, the guy in the vid uses a small screw driver. I always use the end of the hard key.


If the problem is not solved, check the passenger door to see if it acts the same as the driver door. Sometimes the mechanism in the door itself fails. This happened on my ML also. The driver door would not unlock properly, but all other doors did.

Good luck.
