A dead Subaru key fob can be a real headache, leaving you stranded and frustrated. But don’t panic! There are several reasons why your Subaru key fob might be malfunctioning, and many are surprisingly simple to fix. This comprehensive guide will walk you through the common culprits and help you troubleshoot the issue, getting you back on the road in no time.
Common Reasons for Subaru Key Fob Malfunctions
Several factors can contribute to a non-responsive key fob. These range from simple issues like a dead battery to more complex problems requiring professional attention. Understanding these potential problems is the first step towards finding a solution.
Dead Key Fob Battery
The most common reason for a Subaru key fob not working is a depleted battery. Key fobs rely on small batteries to power their wireless signals. Over time, these batteries naturally lose their charge. If your key fob suddenly stops working, a dead battery is the first thing you should check.
Key Fob Programming Issues
Sometimes, the connection between your key fob and your Subaru’s immobilizer system can be disrupted. This can happen after a battery change or other electrical work on your vehicle. In such cases, reprogramming the key fob might be necessary.
Key Fob Damage
Physical damage to your key fob, like a cracked case or water exposure, can also cause it to malfunction. If you’ve dropped your key fob recently or it’s been exposed to the elements, this could be the source of the problem.
Internal Key Fob Component Failure
While less common, internal components within the key fob can fail over time. This might involve a malfunctioning circuit board or other internal parts. Diagnosing this type of issue often requires specialized tools and expertise.
Issues with the Subaru’s Receiver
In some cases, the problem isn’t with the key fob itself, but with the receiver in your Subaru. This receiver is responsible for detecting the signal from your key fob and unlocking the car. If the receiver is malfunctioning, it won’t be able to recognize even a perfectly functioning key fob.
Troubleshooting Your Subaru Key Fob
Now that we’ve explored the potential causes, let’s dive into some troubleshooting steps.
How to Check and Replace Your Key Fob Battery
Replacing the battery is usually a straightforward process. Consult your owner’s manual for specific instructions for your Subaru model. You’ll typically need a small screwdriver to open the key fob casing and access the battery compartment. Make sure to replace the battery with the correct type and ensure it’s properly installed. Similar to how to fix a key fob button, replacing the battery can be a simple DIY fix.
How to Reprogram Your Subaru Key Fob
Reprogramming a Subaru key fob often involves a specific sequence of steps using the ignition and door locks. This procedure can vary slightly depending on the Subaru model, so again, refer to your owner’s manual for the correct instructions. If you’re not comfortable doing this yourself, a Subaru dealership or qualified automotive locksmith can help. Just like how to use your key fob to roll down windows, programming requires following specific steps.
How to Inspect Your Key Fob for Damage
Carefully examine your key fob for any visible signs of damage, such as cracks, dents, or loose buttons. If you suspect water damage, try drying the key fob thoroughly. However, if the damage appears significant, it’s best to consult a professional or consider replacing the key fob. Understanding how to take a subaru key fob apart can be useful in assessing damage.

When to Seek Professional Help
If you’ve tried the basic troubleshooting steps and your Subaru key fob is still not working, it’s time to seek professional help. A Subaru dealership or a qualified automotive locksmith has the expertise and tools to diagnose and fix more complex issues, including internal component failures or problems with the car’s receiver. They can also advise you on whether repair or replacement is the most cost-effective option. It’s always good to be prepared for situations like this, so knowing what if my key fob doesn’t work can be extremely helpful.
Conclusion
A malfunctioning Subaru key fob can be inconvenient, but understanding the potential causes and troubleshooting steps can often save you time and money. Start with the simplest solutions, like checking the battery, and then move on to more complex solutions if needed. Remember, if you’re unsure about anything, seeking professional help is always the best course of action to get your Subaru key fob working reliably again.
