Question about 2001 Mercedes-Benz C-Class

1 Answer

My key will not open the doors or start the engine (it won't even turn in the ignition switch). Initially, I thought it was the battery for the key, but I changed that without success. The light on the dash comes on when I open the the door but other than that, the pedals (gas and brake) are locked. The headlights and the over headlights inside the car come on. I sat in the car and hit the lock button on the key 2x , put in the ignition took it out hit it again, hoping it would reprogram the key-no luck!!

It's possible that your key is bad or no longer works. A way to verify that it is a key problem is to see if the 2nd key or spare key works properly. Check the side of the remote key for a 3 digit #. if the key variant is less then 221 the way to reset it is to put it in the ignition and pull it out 5x with 8secs. If higher than 221 then the no need to try and reset remote key.

New battery In mercedes no power


I'm not a car mechanic, but, it sounds like you might want to check the fuse to the ignition switch, and, if that fails, it might be a problem with the Start Safety Switch on the transmission. Good luck.

The alarm system somehow got activated , this is usually because the battery becomes discharged or disconnected try doing this:
Remove the key from the ignition
disconnect the negative battery terminal
put the key back in and turn to ON
exit the truck and leave door open
reconnect the battery terminal
get in and leave door open, if the alarm horn stays off it should start.

Why wont the keys come out of the ignition or even turn all the way off


Your ignition is shot would be the first thought, since it won't turn to the off position. Is your car engine shut off? If so try and start it or turn the key forward as far as you can and then try to turn it back. If no luck, remove negative battery cable and call it a night.

Possibly an ignition switch, trace the wires off of your ignition and see where your power stop, very time consuming. Lithia Replaced my ignition switch because they thought it was causing a problem set me back $600.

AAA advised me to open and close door with key


Yes. Because the security system was "set". You need the code to unlock the security system for the radio. It is like that for theft pruposes. Best bet is to go to the dealership to have them reset it or figure out how to get the code for your radio.
