Not exactly the case. If you take a look at a few other postings, you'll find that BMW makes only 10 or so keys for each truck and that you need to purchase those keys from the dealer.

The 'board' that you purchased probably opens someone else's car.

I unfortunately fell for the ebay scam and now I have an $80 car unlocker as well.
