The car is a C180, made in 2001.

The problem is that the key is unable to turn. The central locking and the entire electronics has failed. The car is dead.

For the past six weeks, this would happen but after repeated attempts, over upto two hours, the key would eventually turn. But for the last three days at no point would the car start or the key turn. The electronics have completely failed.

Has anyone else experienced this problem. I think this general system has been in use in Europe in E and C classes since about 1999.

Any suggestions as to what this is or how it could be solved. We've checked with a mechanic who has heard of this happening but Mercedes are not being too helpful.

Is there any possibility this is a design fault?

Any help would be much appreciated.

It's not especially common, but it is possible your EIS (electronic ignition switch) unit has failed. As an '01 I imagine you might be under warranty still. If this is the case tow it right to the dealer (warranty even covers the tow if your vehicle is undrivable). If not, it could be an expensive repair. You'll need to have either the dealer or a HIGHLY qualified MB specific indepent check it out. If they don't have a STAR basic diagnostic system, they may not even be able to help you should they determine the problem. Your EIS needs to be re-coded and flashed with a green key when installed, and i don't believe that is an area that generic scanners will allow you to access. This is of course, just a thought, as with these situations, it is deifficult to ascertain the problem without some electrical testing.

Thanks.

Thanks for the help.

That's more or less what we figured too. I'm just trying to see how often this happens, we've heard of it happening to quite a good few cars around here.

Thanks again.

Total failure

I am having a similar problem with my C230 99.
But sometimes the car won't even unlock. I don't think it is the batteries in the keys, since it works sometimes and then suddenly won't.

Mercedes came out and looked at it but could not figure out the problem...
