These are not identical to the old one. I also ordered these in addition to the ones I ordered from Alibaba. Like mentioned, the leads are not in the right place. You can modify it and do additional soldering, but why not just get the one that is already correct - make the job easier/better. It does take a couple weeks to get the ones from alibaba.

If you read the reviews on amazon, lots of people will mention this as well.

If you really, really, really, want to do it the easy way, just send it to Scott at bmwgm5.com and he'll replace the battery for you and check the circuit board for only $50.

But then you don't get that sweet sweet satisfaction from doing it yourself!

I tried doing it myself and jacked up the immobilizer or something.

As much as I hear this guy is honest and fair priced, he said it himself: he can never guarantee work 100% as he doesn't have the car there to test it. Therefore, I'm doing it myself and I have very knowledgeable and skilled electronics guru friend to help me.

You're right but it is Panasonic and the same voltage. Bent leads are not big deal as I have the friend that's more than capable to solder it safely.
