The red key light on a Harley-Davidson motorcycle typically indicates an issue with the security system or immobilizer. Here are a few possible meanings or scenarios associated with the red key light:
Security System Activation: The red key light may illuminate to indicate that the security system is armed. This occurs when the motorcycle is locked using the key fob's security function. It serves as a visual reminder that the security system is active and will trigger an alarm if tampered with.
Incorrect Key Fob or Key Fob Signal Issue: If the red key light remains illuminated even after inserting the key fob into the motorcycle's ignition switch and turning it to the ON position, it could indicate a problem with the key fob itself or a signal transmission issue between the key fob and the motorcycle's security system.
Immobilizer Fault: In some cases, a persistent red key light may indicate a fault with the motorcycle's immobilizer system. The immobilizer is designed to prevent unauthorized starting of the motorcycle. If there is an issue with the immobilizer, the red key light may stay on as a warning.
If you encounter a red key light on your Harley-Davidson motorcycle, it is recommended to consult the owner's manual or contact an authorized Harley-Davidson dealership for guidance. They can provide specific information related to your motorcycle model and help diagnose and address any potential issues with the security system or immobilizer.
