If the chip is damaged or the code is missing, the car will not begin, even if the engine cranks.

They then access the automobile's security system-- often needing a specific "PIN" code from the producer-- and "teach" the car the brand-new chip's unique ID. Once the car accepts the ID, the immobilizer will deactivate when that key is utilized.
