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 inserted into the ignition or the "Start" button is pressed, the automobile sends an electronic burst to the key. The transponder chip reacts by sending a distinct alphanumeric code back to the ECU. If the code matches the sequence stored in the car's memory, the immobilizer is shut off, and the engine begins. If the codes do not match, the fuel pump and ignition system stay disabled.

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