I dropped my key fob for my 1999 ML430. Now the buttons won't lock/unlock it. I've replaced the batteries and no luck.

I've never tried unlocking the car with just the key.. the alarm shouldn't go off, should it?

oops ment to post this in 163...

It will go off. I have a 2001 E320 and that was one of the first things I tried when I got the car - lock it with the remote and open it with a key (I wanted to see if the key works). The alarm does go off, so if you are going to try that, get a working remote first to disable the alarm.

92% of all people suck at math. I am a part of the 9% who don't.

It WILL go off. If it does, just stick the key in the ignition and that should turn it off.

BTW, try resynching the key to get the buttons to work. It should be in the manual.
