Is there any way to reprogram the immobilizer on the spot, without having to take the car to the dealer?

I don't believe the two functions are related. I just picked up a new key for my 2001 X5 and it came from BMW programmed to operate the vehicle but was not programmed to remotely unlock it. This required a quick programming by my indy which I observed while he performed. I did not see anything that could alter the programming of the key to start the vehicle.
My thought is there is something else wrong. Perhaps the key is starting to fail? Do you have an alternate key you can try? I purchased a new key not only because I received a single key when I purchased the vehicle but also because the vehicle intermittently would not turn over unless I performed an off-on cycle of the ignition. Since I've used the new key I have not experienced this behavior (though it's only been a week and a half).
To summarize the key could be the problem.
