No problems ever starting car. Went to the store and came back out;key would not turn. Did not get the the click that usually happens to activate startup system. Car is now in the shop;new ignition has been put in but still wont connect to starter. Key was still operating door locks and lights were working. -

Yes the parts and keys for this car does have to be programmed. I was told that the ignition would come in programmed to my car and the keys I have would work. The car is at a MB dealer and has been there for 10 days. Since replacing the ignition did not work I'm looking for other problems it could have been because I know the price tag is gonna be big and I want to know questions to ask to make sure unnessary work was not done. -
Answer 2
Hopefully a silly question but has anyone tried a different key? My point is that if you use the same key every day eventually it can become damaged. Sometimes the other key would work. -

Answer 3
I had same problem with my 2001 ML 430. Somehow the key de-programs and won't start the car. Lucky for me, I had a spare key. -

Dead car battery. It can still have enough juice to turn on the lights. I've been to several sites, and every one barks about old cars wearing out, but none bothered to suggest you put a charger on the battery...my 2001 e320 has had some electrical issues due to some idiot leaving the sunroof open while misting overnight, and apparently some low level stuff stays on and draws power. Car sat for a couple of days and the battery ran down. As soon as I hooked up the charger, the key turned; now I'm just waiting for enough juice to turn it over. I can't believe none of the "experts" suggested checking the car battery first... -
