Now I don't know if this is true or not, but a CA once told me that other BMW key fobs can wake your car. Because of how the handshake works (and I'm not sure if this is *all* cars or just the ones with CA), if someone else unlocks their BMW, all BMWs in the vicinity also 'wake up' to see if it is the correct key fob, and when yours sees that it isn't, it doesn't respond and goes back to sleep, but nonetheless some of the electronics do wake up momentarily. He said they have issues with the cars on the lot because of how often these little wake/sleep cycles occur. Could be BS, could be true, but sounds plausible.
