Now, this is something I never knew existed – it turns out it is quite possible to use the same wireless car key on multiple cars and to reprogram the key assignment and lock/unlock more than one car with a single key (or do the opposite – reassign several keys to the same car). If this works – I haven’t tested it yet – this can come up really handy.
BTW, I suspect the title is not very accurate – from the description it looks to me that what is being reprogrammed is not the key itself, but the car to recognize the key.
