Question about 2002 Mercedes-Benz M-Class
My key is stuck in the ignition. How do I get it out? The car will not start either, just turns on but the engine won't start completely and I cannot remove key.
Car will only start in park or neutral. key will not come out unless in park. perhaps the car isnt fully in park

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

The starter is turning only when the solenoid close the contact to deliver the current to the starter . When this happens it then turns the bendix to engage with the flying wheel to start the engine.
The reason that you need higher voltage to have correct needed current going through the contact of the solenoid, hence the starter. The contact is corroded or rusty due to high spark at high current at every start time causing high resistance. V=IR the R resistance of the contact now is high so it need higher voltage (14.3 vs, 12.8 V) to deliver the same needed current for the starter.
Unfortunately, the solenoid is integrated with the starter, so you can not just replace the solenoid without replacing the starter.
If you can find the new battery holding at 14.3 V as you mentioned, then that is an economical solution since replacing the starter is costing more.
BTW where can I find the battery at 14.3V in case my friend's car has a same problem?

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.

IGNITION KEY WILL NOT RELEASE
can be faulty ignition lock cylinder. I suggest to wiggle the steering wheel
a bit and see if the key gets released out. If that is not helping
then first turn steering wheel to right and try removing the key, or next turn
steering wheel to left and see if you can remove the key.
wd-40 in the ignition key hole and let it remain there for few minutes, after
that once again try to remove the key and see if that helps.
if that is not helping then ignition lock cylinder has to be removed out and
key has to be manually removed.
