Why Does My Subaru Key Fob Battery Die?
Key fob batteries, like all batteries, have a limited lifespan. Factors like frequency of use, extreme temperatures, and even just the passage of time contribute to battery drain. A dying battery can manifest as reduced range, intermittent functionality, or a complete inability to lock or unlock your car.
Knowing how to change the battery yourself can prevent being stranded. It’s a quick process that can be done at home with minimal tools. This guide applies to various Subaru models, and while the specific steps might vary slightly, the general principles remain the same.

How to Change Battery on Subaru Key Fob
Gathering the Right Tools
Before you start, gather a small flathead screwdriver or a similar tool for prying open the key fob casing. You’ll also need a replacement CR2032 battery, readily available at most stores.
Locating the Key Fob Release
Most Subaru key fobs have a small release button or slot. This is usually located on the side or back of the fob. Press this button and gently separate the two halves of the key fob.
Removing the Old Battery
Once the fob is open, you’ll see the battery. Carefully pry out the old battery with your flathead screwdriver, being mindful not to damage the surrounding components.
Installing the New Battery
Insert the new CR2032 battery, making sure it’s oriented correctly. The positive (+) side should typically face upwards. Press the battery firmly into place.
Reassembling the Key Fob
Align the two halves of the key fob and snap them back together. Test the fob’s functionality by locking and unlocking your car.
Troubleshooting Common Issues
Sometimes, the key fob might still not work even after a battery change. This could be due to a few reasons:
- Incorrect Battery Installation: Double-check that the new battery is installed correctly and securely.
- Key Fob Programming: In rare cases, you might need to reprogram your key fob after a battery change. Consult your owner’s manual for specific instructions.
- Other Key Fob Issues: If the problem persists, there might be a more serious issue with the key fob itself, requiring professional attention.
