At the heart of this system is the transponder chip, located inside the head of the key or the body of the key fob. When the key is placed into the ignition or the "Start" button is pressed, the automobile sends an electronic burst to the key. The transponder chip responds by sending a special alphanumeric code back to the ECU. If the code matches the series kept in the vehicle's memory, the immobilizer is shut off, and the engine starts. If the codes do not match, the fuel pump and ignition system stay handicapped.

- Signal Synchronizing: The new key is presented to the system. The programming tool instructs the ECU to accept the new transponder code.
- Checking: The technician validates that the remote functions (lock/unlock) work which the transponder successfully bypasses the immobilizer to begin the engine.
