Hi all, I've had issues with my eis not starting and got some advice from here, thanks. It would worsen in cold weather so I expected the issue to be a defective eis. I found a guy on eBay who claimed able to pull your code and install it in another eis. I did this. I sent him my eis and key and he sent one back. My keys will turn in this one no problem, but the car will not start. The very first two times I tested this, the car did start, but cut off in a matter of seconds. Now, no start. Key can turn all the way, a.c./heat blower will work and radio turns on, but car won't crank. Am I right to assume it's security related? Any advice on how to proceed? I've reached back out to the guy to see if he can return my original eis.

Also, if it means anything, my radio code will not work. Not sure if this further proves any anti-theft security measures kicking in or not.
Another thing, I broke a connector piece when I removed my original. I cut out the piece from a 99 c class and connected it to the piece from the car. See picture.

Thanks!

 

I'd say you got snookered....now its off to the dealer for a new one.

 

So I told him the first one he sent didn't work and he sent another. Same issue, but then I realized anything powered (lights windows, etc) were working slow or dim. I replaced the battery and the first one he sent me is working. Car starts and remains on no issues. I tried the second, and that doesn't work. I told him I'll send it back so him so he has another one he can reprogram for another customer. The second one has a different number (model #?) Than the first one and my original one. I'm guessing that's why it doesn't work.
