I have a 2002 c240 with 98,450 miles. Yesterday I went out to move the car for the first time in 2 weeks, no cranking engine over but the cooling fans start running full blast under the hood. I had My first issue week before of when I stuck the smart key in it wouldn't turn in the ignition. I put it in and out a couple times and then it did start no problem. No check engine lights on either besides the normal one about replace brake bulb but that's a lie hahaha. My key fob battery has been low cause couldn't always lock or unlock my door so I replaced them and now both work very well but neither key will start car. Just the cooling fans run on high and no cranking over. Any ideas besides its time to ship the old girl down the road for a new one ? Oh and btw did try to pull codes but I don't believe I have any communication at the diagnostic port..??help!
