BMW stands for "Blew my wad"

Those chips in the keys are not related to the batteries in the remote. At least not on anything else I've ever worked on and that's included BMW. I find it really strange BMW has no toll free number to call and get a signal shot from a satellite to unlock the doors. Most any other high end cars do. If my 100,000 buck plus modern car did not, that sumbitch would be goin in for a refund. That's just flippin stupid. If they don't offer that service.
