A malfunctioning key fob can be a real pain, especially when you’re trying to get somewhere on time. If your 2009 Subaru Legacy key fob has stopped working, don’t panic! This is a common issue with a variety of potential causes, most of which are easily fixable. This article will guide you through the possible reasons your key fob isn’t working and provide effective solutions to get you back on the road quickly.
Common Causes and Solutions
There are several reasons why your 2009 Subaru Legacy key fob might not be working. Here’s a look at the most common culprits:
1. Dead Key Fob Battery
This is the most common and easily resolved issue. Like any battery-powered device, your key fob battery will eventually die.
Solution:
- Consult your owner’s manual to determine the correct battery type for your key fob.
- Carefully open the key fob casing.
- Replace the old battery with a new one, ensuring it’s positioned correctly.
- Reassemble the key fob.
- Test the key fob to see if it functions properly.
2. Weak Key Fob Signal
Over time, the signal transmitted from your key fob to your car can weaken, leading to intermittent functionality or complete failure.
Solution:
- Ensure that you are within a reasonable distance of your vehicle when attempting to lock or unlock it.
- Check that there are no electronic devices or obstacles interfering with the signal transmission.
3. Key Fob Programming Issues
If the battery is new and you’re confident the signal isn’t the problem, the issue might be with the programming of your key fob. This can occur after a battery change or if the key fob has been exposed to an electromagnetic field.
Solution:
- Consult your owner’s manual for instructions on reprogramming your key fob.
- Some vehicles have specific steps you can follow at home, while others might require a visit to a Subaru dealership or qualified automotive locksmith.
4. Faulty Key Fob
In some cases, the key fob itself might have a malfunctioning component that prevents it from communicating with your vehicle.
Solution:
- If you suspect a faulty key fob, it’s best to consult a qualified automotive locksmith or your Subaru dealership.
- They can diagnose the problem and advise you on whether the key fob can be repaired or needs to be replaced.
5. Issues with Your Vehicle’s Receiver
While less common, it’s possible that the issue lies with your Subaru Legacy’s receiver, not the key fob itself. This can be due to a blown fuse, wiring problems, or a faulty receiver module.
Solution:
- Diagnosing and repairing vehicle receiver issues typically require specialized knowledge and tools.
- If you suspect a problem with your car’s receiver, it’s best to take it to a qualified mechanic or your Subaru dealership.
