It could be a failed key !! haveyou tried your spare key ? if not it could be the EIS or ESL (electronic steering lock )

Reset your Mercedes-Benz key by placing the key in the ignition of your vehicle while the vehicle is turned off. Do not turn on the vehicle. Press a finger on the "lock" button of your key fob while the key is in the Mercedes' ignition.

Pull the key out of the ignition while continuing to hold the "lock" button down. Continue to hold the "lock" button for the duration of the key resetting process

Use another finger to push down on the "unlock" button five consecutive times. Keep holding down the "lock" button.

Release the "lock" button. This is the end of the resetting process for your Mercedes-Benz. Use your key fob to ensure it is properly working

probably similar system to fords smart lock. they have a module located under the dash on the left of the steering wheel. a common fix for them is to hit the dash in that spot & it will always go. Just call an auto elec & ask if it has something like the smart lock module, if that is the probable cause, then how much to diagnose & repair.

May need to reprogram key to vehicle

1. Some times the keys wear out. Do you have a spair key you can try.
2. Turn the steering wheel back and forth while trying to turn the key sometime the steering wheering lock will bind.
3. Now the bummer part is the ignition lock will have to come out so you can determine what part froze up.

I have a 2001 C240 with the same issue. I removed the positive battery cable from the battery and kept it off for 30 seconds then replaced it. Everything was reset and the key worked.

Hi there
I had something similar on my merc
but yours sounds similar.
the fact that you say the steering lock no longer works is very worrying, most times the key not going past position 1 is due to the steering lock being actuated and the pressure in it has to be released before the key will turn, you will have to go from lock to lock the find where the steering lock actuates when this happens follow my wiggle method of turning the steering wheel slightly when the steering lock is on the disengage it. ie keep trying the key whilst wiggeling the steering wheel.
hope that helps

hi,seem your steering lock mechanism is defective,if you to try,remove your under dash,you can your steering lock, loose bolt in clamp,fine a small lock drill out,then you can turn your ignition switch,you can also remove the wiring in the back of steering lock,renew your lock mechanism,ty

Hi! Sounds like the key needs to be coded again, take all relvant details i.e. chassis vin number, Registration document (Title) and key to your local Mercedes Dealership and hopefully they'll rec-code it for youor replace it.
Good Luck and a Happy New Year to You and your family.
