I hope I am wrong, but I expect it is the ignition module. To fix it the steering lock will need to be smashed off, the ignition barrel and electronic module replaced and a new key provided.
The key and module will need to be coded in Germany.
It is a $1,900 fix (plus towing) and there is no way to move the car to Mercedes except on a truck.
As said: I hope I am wrong.

Yikes!
Sounds like a good anti theft mechanism. LoL

Hmmmm I'd like to thank you that bit of info!Was given that sort of quote from the Merc dealer.My partner is a mechanic (unfortunately gave up early into the electronic era), he managed to correctly diagnose the airflow sensor and we got one off Trade Me that he put in.But does it really look like this one is beyond his magic wand!

Yep grangies don't buy a car with an electronic key!

It will be a dashboard and locksmith job.

If, and only if, my diagnosis is correct then there is little to be gained from doing the work yourselves. The money is largely in the parts, and the Mercedes anti theft stuff is so 'secure' that there is no way that I know of to bypass the systems. You are forced to work with genuine Mercedes parts and German coding done specifically for you.
I asked the value of the car for a reason. Not every vehicle is worth spending $2k on, but that decision is yours of course.
Good luck

No it's not worth spending that.Thanks for your help unclejake.Looks like I can't even put it on the side of the road for someone to nick!I gotta laugh or I'll cry.

Dashboard, as in.
Someone who is good at removing small parts, then putting them back together.
Doesn't have to be a dashboard.

Bet it doesn't (LOL)

Good point. (Bob is worth listening to when it comes to Kraut).

Second the car battery as above.

I sincerely hope you are right Bob. A $300 calcium battery would be cheap! (comparatively)

I second Bobs educated guess of the car battery. The key will NOT turn without power, it works on a transponder that requires power like a traditional blade key. Have you had the battery disconnected by chance! The batteries in the key have nothing to do with starting the car they simply power the remote central locking, it should start without them. Check the car battery first.

Now I know how John feels when everyone is ganging up on him and calling him names (such as John)
You guys are ruthless!
robbiexmas,

You're right unclejake it doesn't.Of course the first thing we did was disconnected and reconnected the battery to perchance reset the computer.We even tested the battery (even though it is relatively new).

^ The problem in the E cars can be intermittent. I assume the C class is the same hardware.
I bet that guy who was praising the lord, was cursing the motherland again within a few months when the key didn't turn for him one rainy night in Georgia

I bet a lot of folk have praised Bob1120 too.
Anyway, you know more about Euros than most of us so let's hope Robbiexmas can get a jumperpack onto that Merc and that the ignition comes right.
Fan blower controls, automatic gearboxes and ignition faults are the death of these mid-late 90s Mercs.
