A Comprehensive Guide to Emergency Car Key Programming

Each key consists of a distinct digital signature. When the key is inserted or the "Start" button is pushed, the car sends out a request to the key. If the key's reaction matches the code saved in the ECU, the immobilizer is disengaged, and the engine starts.

If this synchronization is lost-- whether due to a dead battery, a hardware glitch, or physical damage-- the car becomes an unmovable things.
