Multi-factor authentication for car (unfinished yet)

Introduction and problem

I want to solve the problem of reliability keyless car systems.

Excerption: The car companies responded by developing a ‘rolling code’ system, which changes the code with every use. If an already-used code is used again, it is rejected, meaning that codes can’t be recorded or stored.So RollJam ‘jams’ the signal when the button is first pressed, using basic radio technology from garage door openers. As the first signal is being jammed, a radio transmitter records the wireless code transmitted from the key fob.When the driver presses the button again, RollJam simultaneously broadcasts the first code and records the second, meaning that the car thinks its getting the code for the first time, the key device thinks its sending a second code – and the driver thinks nothing of it.The second code is then stored for later use. No matter how many times the key is pressed and the car is unlocked, RollJam follows the same process and the code stored by the device is always ‘fresh’.
