How CIS Works
CIS operates through a series of steps:
- Key Insertion: When the vehicle's key is inserted into the ignition switch, it activates the transponder chip.

- Signal Reception and Authentication: The receiver unit receives the signal and compares it with the authorized code stored in the vehicle's immobilizer module.
- Ignition Enablement: If the signal matches the authorized code, the immobilizer module sends a signal to the ignition switch, allowing the engine to start.
- Ignition Disablement: If the signal does not match or is not received, the immobilizer module disables the ignition, preventing the vehicle from being started.
