You are talking about encryption and encryption is definitely implemented in all keys. The problem is that the suitcase attack is purely a relay (man in the middle) attack. It doesn't modify or touch the signal. It simply sends whatever signal the key sends to the car and vice versa. No amount of encryption can help that.
