Bad EIS? Old key cranks car, but won't start, new key gives "remove key"
This is now my third post here regarding the same car, and I'm just about ready to sell the dang thing. At first, my car would not start. Steering wheel unlocks, nothing. So I myself replaced the shifter, which now allowed my dash to read what gear I'm in, and crank the car. Steering wheel unlocks, pressure and fuel coming from the fuel pump to the engine as it should, and everything in the dash is looking good. Also has a brand new battery. The weird thing is, I can crank the car 3 times, it cranks for anywhere from 3 to 15 seconds if I'm pumping the gas pedal. After these 3 tries, the battery needs to be unplugged and replugged, then I get 3 more cranks.
Under recommendation from my mechanic at the local MB dealership, I purchased a new key as he said this will be the most economical step forward, and could very well solve my issues. New key comes, no dice. With the new key, it unlocks and locks the car just fine. It was already programmed by the dealership by the time I got up there (the car is sitting in the back lot, I used to work there in sales). The old key still functions as described above, but the new key immediately says "remove key" when I plug it in, and does not turn in the ignition. Also, for the first time today I noticed the old key also says to remove key, but that message goes away as soon as I begin to turn it (I forgot to check if the steering wheel unlocks).
Can anyone help me out and point me in the right direction here? I'm assuming the EIS needs to be repaired/replaced, which the dealership offered for over $1k to do, and my mechanic says he knows a company that'll repair it for much cheaper. I also saw some vendors on ebay and other sites offering the repair for $350, but I'd want to know the efficacy and success rate of such repairs before spending anymore on the car. Thanks in advance.
