I think with a regenerating code, there needs to be an easier way to deal with the fob getting out of sync. It would be pretty annoying to miss the fob hit and then have your vehicle become unusable.
The way @Oka described it the fob would only change the code if the car sends a new code. So if you're out of range the fob would send the same code again on the next press.
However, if the dealership can reset the fob and car then in due time so will any criminal, either by acquiring the necessary hard- and software from a dealership going out of business or someone reverse-engineering it.
