If the codes do not match, the fuel system is handicapped, and the car stays stationary.
Key Components of Modern Car Keys

| Transponder Chip | Communicates with the immobilizer to allow engine ignition. |
| Remote Fob (RF) | Uses radio frequencies to lock/unlock doors and activate alarms. |
| Smart Proximity Chip | Enables keyless entry and "start" button performance without physical contact. |
Common Scenarios Requiring Reprogramming Services

3. Cloning
Some older or simpler transponder systems enable "cloning." This is where the information from an existing working key is copied onto a blank chip. While efficient, it does not permit for the deletion of lost secrets, as the car sees the clone and the initial as the same entity.
