I have a 2003 C32 and when I use the manuall key to open or close the door, it will only lock/unluck the drivers door and if the car was locked it sets off the alarm. Any ideas to a fix? The doors lock/unlock with the fab.Thanks.

The manual key is a backup so you can get into the car if the fob battery is dead. It's forcing the lock open, not unlocking the car. Alarm should go off once you stick the fob into the ignition.

Thanks for the info.
Looking at the older MB they would unlock all the doors when you used the key, thats why I was sure someting is damaged or wrong. But like you say, the alarm turns off as soon as the ignition is on.

Thanks.
