As you know the battery in your key not only operates the courtesy controls, it also sends a signal to a sensor in the vehicle that allows the key to be used. Either the chip in the key is faulty or the onboard system is not recognizing the key. Call the dealer(sorry, hate giving that advice) and tell them the same. Have them start with the key first, so to keep the cost down a little. You could check through the technical book for a relay or fuse associated with the security system of the vehicle. You can get this online as a PDF file.

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

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.
