If your Subaru key fob won’t work, you’re not alone. This is a common issue, and understanding why it happens can save you time, money, and frustration. This guide covers everything from simple fixes like battery replacement to more complex programming issues, offering solutions for Subaru owners, mechanics, and automotive technicians.
Common Reasons Why Your Subaru Key Fob Won’t Work
Several factors can contribute to a malfunctioning Subaru key fob. Here are some of the most frequent culprits:
- Dead Battery: This is the most common reason. Key fob batteries typically last 2-3 years, but their lifespan can vary.
- Key Fob Programming Issues: Sometimes, the key fob loses its programming and needs to be reprogrammed to communicate with your car.
- Faulty Key Fob: Internal damage or wear and tear can cause the key fob to malfunction.
- Car Battery Issues: A weak or dead car battery can sometimes interfere with the key fob’s signal.
- Signal Interference: Other electronic devices or structures can sometimes block the signal between the key fob and your car.
- Keyless Entry System Malfunction: Problems with the car’s keyless entry receiver can prevent it from recognizing the key fob’s signal.
Troubleshooting Your Subaru Key Fob
Before rushing to a dealership, try these troubleshooting steps:
- Try the Spare Key Fob: If your spare key fob works, it confirms the issue lies with the original key fob and not the car’s system.
- Check and Replace the Battery: This is the easiest fix. Consult your owner’s manual for the correct battery type and replacement instructions. Often, a small flathead screwdriver is all you need. You can learn more about battery replacement here: 2016 subaru outback key fob battery replacement.

- Try Moving Closer to Your Car: Sometimes, signal interference can be the problem. Try standing closer to your vehicle when using the key fob.
- Test Different Locations: If you’re near a building or structure with strong electronic equipment, try moving to a different location to eliminate potential interference.
