The green key light typically indicates the immobilizer system in your Honda CR-V is active and functioning correctly. The immobilizer system is an anti-theft feature designed to prevent unauthorized vehicle starts. When you insert your key into the ignition and turn it, the key sends a unique code to the immobilizer control unit. If the code matches the one stored in the control unit, the light turns off, and the vehicle can be started. If the light remains on, the immobilizer system has detected an issue, and the vehicle will not start.
Here are a few reasons why your Honda CR-V's green key light might be on:
* The key or key fob is damaged or faulty.
* The immobilizer control unit is malfunctioning.
* There is a problem with the wiring between the key, ignition, and immobilizer control unit.
If you're having trouble starting your vehicle due to the green key light, you should have the issue diagnosed and repaired by a qualified mechanic.
