There are three types of transponders: Fixed Code, Rolling Code and Crypto.

Fixed code transponders always have the exact same code in the chip. The code is sent one way from the chip to the cars computer. Rolling code transponders data is sent both ways from the computer and chip. It first verifies the code from the key and then changes it code. The new code is sent to the key. When both codes are changed and accepted the vehicle will start.
