The Ultimate Guide to Car Key Reprogramming Services: Technology, Process, and Necessity

If the code matches what is saved in the ECU's memory, the immobilizer is shut down, and the engine starts. If the codes do not match-- or if the chip is missing-- the car will remain immobile, even if the physical blade of the key turns the ignition.
