Hello - my first post here - thanks for taking the time to read about my issues..

I have a 2007 CLS 550, which this morning, just didn't want to start-up for me. I have key-less start and leading up to today, had a few problems occasionally with my key not being recognized for a few seconds (I assumed the battery in the key was dying).

This morning when I went to start my car - nothing - the engine attempted to turn over once but didn't manage to start. All the lights on the dash and the radio worked fine - leading me to believe it's not a battery issue (with the car at least).

I tried putting the key in the ignition and turning - and nothing..

Yesterday, while at a gas station, the car had some problems starting - but only for a few seconds - and then it fired right up..

I plan to take the car to the dealership, but I was wondering if anyone had any insight into what the problem might be? My key? Battery? Alternator? Starter Motor?

Any help or advice would be greatly appreciated - thanks!

Thanks S500 Man - I got home from work (about 10 hours later) and the same thing is happening - all the lights on the dash are working fine, but no starting - no cranking at all...

I've tried a few of the things that I've read on the forum - using a different key, moving the steering wheel, trying in neutral - no luck..

Any ideas on how to trick the car to start so I can at least drive it to the dealership?

Thanks..
