Not quite sure I get this. It's a decent idea but...
I have 2 keys for my car. My wife has one and I have one. I press to unlock the car, the fob and the immobiliser change codes. Haven't I just made my spare key completely useless?
Maybe a hash based on time stamp or something but I think the above method is a little impractical.

The car knows you have two keys for your car. So it knows when you use one key or the other.

It has a rolling window of codes for the registered key fobs,mind press it 100 times away from the car and it wil then be useless :D

Pretty sure it doesn't change until it gets confirmation from the car that the action has occured.
