I saw this key available on ebay:

Here is the info on the back of the key:

315 MHz

Siemens VDO 5WK49147

FCC ID: KR55WK49147

IC: 267T-5WK49147

BMW 6986579-01

My key has all the same exact info on the back, with the exception of the very last digit, here is the info on my key:

315 MHz

Siemens VDO 5WK49147

FCC ID: KR55WK49147

IC: 267T-5WK49147

BMW 6986579-02

From the picture, the channel cut in the key looks different from mine, but my questions are:

Is there any way this key will work with my car? How much would it cost to reprogram it? How many different codes are there and what are my chances of actually finding one that matches perfectly?

I guess I should probably tell you why I want this for a third key: I want to cannibalize it and make it into a "super key", which is why I don't want to buy it from a dealer. I also have a Lexus GS350 with their version of comfort access and I think it would be awesome to put both transponders in one box so I would only have to carry one key.

Any thoughts?
