Hi all, Hopefully someone can point me in the right direction here. I have an old w210 e430 in the barn. I left the key in the ignition when the car was in the barn for about 3 months, and the battery obviously went flat. Put on a new battery (fully charged), and the key now does nothing. You don't get that electrical click from the steering lock when putting the key in or out. I cannot turn the key. The steering lock is disengaged. I have two keys that both use to work, but the same fault exists with either. I can lock/unlock the car with the remote buttons from either key, but I know that part is a different circuit powered by the key battery. Can anyone help please? I wonder if I've burnt out the coil that powers the key when you put it in the ignition barrel?
