If you’ve ever seen a red key light on your Harley-Davidson motorcycle, you may wonder what it means. 

This light serves as an important indicator of the state of your bike and can alert you to potential problems that need to be addressed. 

In this article, we will discuss what the red key light means on a Harley, why it appears, and how to address any issues that may come up when it does appear. 

What Does the Red Key Light Mean on a Harley

1. How to Identify and Locate the Red Key Light 

The red key light on a Harley is usually located on the dashboard and can be easily identified by its distinct color. 

This light serves as an indicator for Harley riders to know when the security system has been activated. 

The security system was designed specifically for Harley motorcycles and connected to the ignition switch, allowing an engine to start only if the correct key fob is used. 

When the security system is activated, the red key light will blink rapidly with each press of the ignition switch until it goes off after a few seconds once a valid code is sent from the key fob.

2. What Causes the Red Key Light to Illuminate 

The red key light on a Harley Davidson motorcycle indicates that the ignition switch is not in the “ON” position. 

This could be caused by something as simple as forgetting to turn it on before attempting to start the bike, or it may indicate a more serious issue with either the switch itself or its connections. 

In any case, if you notice this warning light illuminated, you should stop and check your ignition switch before continuing.

3. How To Troubleshoot and Reset The Red Key Light 

The red key light on a Harley indicates that there is an issue with the security system. 

To troubleshoot this issue, check the battery and charging system first, as low voltage can cause the light to come on. 

If that does not fix the issue, the key fob may need reset by pressing and holding the start button for at least five seconds or until you hear a click. 

Resetting the key fob will require entering your PIN code if it has been set up as part of your security system. 

It may also be necessary to reprogram any additional fobs if they have been added to your system. 

If none of the above steps resolves the issue, contacting a professional Harley technician is recommended for further diagnosis and repair.

4. Why Does The Red Key Light Indicate an Issue with Your Bike 

The red key light on a Harley indicates that there is an issue with the bike’s ignition system. 

When the light is illuminated, it generally means that there is a problem with the security system, which prevents the ignition switch from operating correctly. 

It can be due to a faulty component in the system, an incorrect signal from the key fob, or potentially a drained battery. 

In any case, it is important to identify and resolve the issue quickly, as it may cause further damage to your bike if left unattended.

5. What To Do When the Red Key Light Continues to be Illuminated

When the red key light on a Harley Davidson motorcycle continues to be illuminated, it usually indicates an issue with the bike’s security system. 

This could mean that the bike is not recognizing your key or ignition switch, which may be due to a faulty or damaged key or switch. 

In order to address this issue, a qualified mechanic should inspect and diagnose potential problems with the bike’s security system. 

In some cases, a new key or ignition switch may need to be installed in order to get the bike running again. 

It is also important to have your bike regularly serviced by a professional in order to ensure its proper performance and safety during operation.


In conclusion, the red key light on a Harley Davidson motorcycle is an indicator of security and should not be ignored. 

It can mean several different things depending on what type of system your bike has installed. 

If you are experiencing any issues with the security system or have concerns about it, contact your dealer for assistance as soon as possible to ensure that you get back out riding in no time. 

With proper maintenance and an understanding of how to interpret warning lights like this one, you will be able to enjoy many miles ahead on your beloved Harley Davidson motorcycle.
