Harley Davidson Not Recognizing Key Fob – Troubleshooting Tips and Solutions

Harley Davidson motorcycles are renowned for their timeless design, ferocious engines, and cutting-edge security components. To start the bike and deactivate the alarm system, you must have a key fob – one of Harley’s signature safety features.

Unfortunately, some owners have experienced the disheartening issue of their Harley Davidson not recognizing key fob. To provide them with assistance and guidance on this problem, we’ve prepared a comprehensive article outlining several ways to troubleshoot and resolve it.

Understanding the Problem

The owner of a 2007 Road King Custom Harley Davidson experienced an issue wherein the key fob was not being recognized. Consequently, the alarm emitted a chirping sound which served as warning that no fob had been detected, and the motorcycle would subsequently not start up.

After a full night of charging the battery, the owner gave it another go; nonetheless, there was no progress. He exchanged out the power supply in the key fob too and yet still encountered unsuccessful results.

Have you ever wondered whether your motorcycle’s pre-installed security system will still work if its battery has been drained or removed? The answer is a resounding yes. Even if the battery of your motorbike fails, it won’t affect the factory alarm’s functionality.

When the motorcycle is shipped from the factory, a distinct battery powers its alarm system. Sadly, if the key fob’s battery runs out of juice, it may not be able to recognize it and therefore will fail to start up.

Troubleshooting Tips and Solutions

Are you having difficulty with your Harley Davidson not recognizing key fob? If so, don’t worry. Here are several helpful troubleshooting tips and solutions to get you back on track:

Check the Key Fob Battery

Before doing anything else, ensure that the battery of your key fob is still functional and inserted in its correct place. If not, replace it with a new one from any dealer near you. But if all seems to be okay with the battery status and insertion, then resetting the key fob could help – walk away from your bike until it can no longer detect your presence; wait for some time till the system resets itself and come back again to give it another try.

Bypass the Security Without the Fob

If your key fob has stopped functioning, you can still access your security system without it. Here’s how:

  • Turn your ignition ON
  • When the red security light begins to blink, press and keep pressing down on the left turn signal button.
  • In no time, the odometer will prompt you to enter your personal identification number.
  • The left turn signal button will help you cycle through the numbers, while the right allows you to select each individual digit.
  • Once the correct 5 digit PIN has been typed in correctly, you will be able to start the bike just as if you had a key fob.

Not sure what your PIN is? No worries, a dealer can easily reset it for you.

Check the Motorcycle Battery

After ensuring that the key fob battery is adequately charged and inserted correctly, it’s important to assess the motorcycle battery. Verify that your motorcycle’s power source is indeed up and running – if not, there may be insufficient energy available to sense the presence of a valid key fob signal.

Consult the Owners Manual

To ensure the best experience with your Harley Davidson motorcycle and its security system, it is essential to meticulously read every detail of the owner’s manual. Doing so will reveal valuable troubleshooting tips that can help you avoid any issues while enjoying your ride.

Seek Professional Help

If all the above troubleshooting techniques and solutions have failed to solve your issue, it’s time to seek expert assistance. Take your motorcycle to a Harley Davidson vendor or certified mechanic who is experienced in dealing with Harley Davidson motorcycles’ security system. They will diagnose the problem and offer an answer promptly.

How Does Harley-Davidson Security System Work?

To protect your Harley-Davidson motorcycle from theft, the iconic brand has designed an advanced security system that relies on a key fob which transmits a distinct code to the vehicle’s control module.

The moment your key fob is in range, the control module will pick up on its code and get your bike running. But if it’s not present or doesn’t recognize the code, an alarm will sound and disable the ignition system—ensuring that no one can start your motorcycle without proper authorization.

In the event of a security system malfunction, consulting the owner’s manual should provide helpful guidance for resolving it. If all else fails, switching your Run/Stop switch to “Run” mode can be an effective solution in helping you get back on track and start your motorcycle again.
