A significant consequence of this attack is that the original, legitimate keyfob is immediately desynchronized from the vehicle and ceases to function. This could be the first sign for an owner that their vehicle’s security has been compromised.

How does this work if a family is using two keyfobs? Does each one have its own rolling code?

Yeah I would assume there's a maximum number of fobs you can register to an individual car and it just keeps the state for all of them individually

That's the only way I think it could work. Makes sense. Thanks for your input.
