Common Causes for Harley Key Fob Not Working
Here is a list of common causes why your Harley key fob might not be working.
Dead battery in key fob
A dead battery is the most common cause of a non-working Harley key fob.

You may also notice that the LED light on your key fob is not blinking or illuminating at all.
Reasons: The most common is simply old age, as batteries have a limited lifespan and will eventually need to be replaced.
Exposure to extreme temperatures can also drain the battery more quickly.
Additionally, if you frequently use your key fob for remote start or unlocking/locking your motorcycle, it may wear down the battery faster than usual.
Solutions: If you suspect that a dead battery is the cause of your non-working key fob, try replacing the battery with a new one and see if that solves the issue. If not, make sure the battery is inserted correctly and securely in the key fob.
Over time, the buttons on your key fob may become damaged or worn out This can prevent them from working properly and cause issues with locking/unlocking your motorcycle.
Symptoms/Signs: The most obvious sign of a damaged or worn out key fob button is when it becomes difficult or impossible to press them down. You may also notice that the buttons are cracked or missing pieces.
Reasons: Regular use over time can wear down the buttons on your key fob. Exposure to harsh conditions such as extreme temperatures or moisture can also contribute to their deterioration.
Solutions: If you suspect that damaged or worn out buttons are causing problems with your key fob, you can try cleaning them with a small amount of rubbing alcohol and a cotton swab.
If that doesn’t work, you may need to replace the buttons or even the entire key fob.
Faulty key fob circuit board
In some cases, the issue may not be with the battery or buttons, but rather the internal circuit board of your key fob.
This is responsible for sending signals from the buttons to your motorcycle’s central locking system and if it becomes damaged or malfunctioning, it can prevent the key fob from working properly.
Symptoms/Signs: The most obvious sign of a faulty circuit board is when the key fob buttons do not respond at all, even after replacing the battery. You may also notice that the LED light on your key fob does not flash when pressing the buttons.
Reasons: A faulty circuit board can be caused by various factors such as water damage, physical damage, or simply wear and tear over time.
Solutions: If you suspect that your key fob’s circuit board is the issue, it is best to seek professional help for repair or replacement. Attempting to fix it yourself can cause further damage and potentially render the key fob unusable.
Interference from other electronic devices
Another common issue with key fobs is interference from other electronic devices. This can disrupt the signals being sent from your key fob to your motorcycle’s central locking system, resulting in it not working properly.
Symptoms/Signs: If you notice that your key fob only works sporadically or in certain areas, it could be a sign of interference. You may also experience delayed response times when pressing the buttons on your key fob.
Reasons: Interference can occur due to various factors such as nearby cell phones, wireless routers, or even power lines.
Solutions: To avoid interference, try keeping your key fob away from other electronic devices when using it. You can also try changing the frequency of your key fob or using a signal booster to improve its range.
Faulty wiring or connection
In some cases, the issue may not be with the key fob itself, but rather with the wiring or connection between the key fob and your motorcycle’s central locking system.
Symptoms/Signs: You may experience sporadic response or no response at all when using your key fob. You may also notice that the LED light on your key fob is dimmer than usual.
Reasons: Faulty wiring or connections can occur due to wear and tear over time or damage from external factors such as water or physical impact.
Solutions: If you suspect faulty wiring or connections, it is best to have a professional inspect and repair them. Attempting to fix it yourself can be dangerous and may cause further damage.
Malfunctioning receiver in motorcycle’s ignition system
Another possible cause for a malfunctioning key fob is a problem with the receiver in your motorcycle’s ignition system. This receiver is responsible for receiving signals from your key fob and sending them to the central locking system.

Reasons: Water damage can occur due to accidents or exposure to extreme weather conditions.
Solutions: If your key fob has been damaged by water, it is important to act quickly. Remove the battery and dry all components thoroughly before attempting to use it again.
If the key fob still does not function properly, it may need to be replaced.
Low signal strength from the key fob
Sometimes, the issue with a malfunctioning key fob may not be due to physical or water damage, but rather low signal strength. This can occur when the battery in the key fob is running low or if there are obstacles blocking the signal.
Symptoms/Signs: A key fob with low signal strength may have difficulty unlocking/locking the car doors from a distance or may require multiple attempts to do so.
Reasons: Low signal strength can occur due to a dying battery or interference from objects.
