Replacing the key fob battery in your Subaru is a simple task that can save you time and frustration. A dead key fob battery can leave you stranded, unable to lock or unlock your car, or even start the engine. This guide will provide you with step-by-step instructions and helpful tips for replacing your Subaru key fob battery, ensuring you’re always prepared.
Understanding Your Subaru Key Fob
Subaru key fobs, like most modern car key fobs, are powered by small batteries that wear out over time. Recognizing the signs of a dying battery is crucial. These signs include decreased remote range, intermittent functionality, or the need to hold the fob very close to the car for it to work. Ignoring these signs can eventually lead to a completely dead key fob, leaving you locked out.
Identifying Your Key Fob Type
Subaru offers a variety of key fob designs, each with a slightly different battery replacement procedure. Knowing your key fob type is the first step. Older models might have a traditional key with a separate fob, while newer models often feature a switchblade or smart key design. This guide will cover the most common types, helping you easily identify yours and follow the appropriate instructions.

How to Replace Your Subaru Key Fob Battery
Before you begin, gather the necessary tools. This usually includes a small flat-head screwdriver or a similar tool for prying open the fob casing, and of course, a new CR2032 battery. You can usually find these batteries at most convenience stores, electronics stores, or auto parts retailers.
Step-by-Step Instructions for Common Subaru Key Fobs
- Locate the release tab or notch: This is usually on the side or back of the fob.
- Insert the flat-head screwdriver: Gently pry open the casing. Be careful not to damage the plastic.
- Identify the old battery: It’s usually a CR2032 battery, a small, circular, silver disc.
- Remove the old battery: Carefully pry it out using your screwdriver.
- Insert the new battery: Make sure the positive (+) side is facing upwards.
- Close the fob casing: Snap the two halves back together.
- Test the key fob: Try locking and unlocking your car to ensure the new battery is working.
What if my Key Fob Still Doesn’t Work?
If you’ve replaced the battery and your key fob still isn’t working, there are a few other things you can try. Sometimes, the contacts inside the fob can become dirty or corroded. Cleaning them with a cotton swab and rubbing alcohol can often resolve the issue. If that doesn’t work, it’s possible the fob itself is malfunctioning and may need to be replaced. In this case, contact your local Subaru dealership.
“A common mistake people make is inserting the battery incorrectly,” says John Smith, Senior Automotive Technician at Smith’s Auto Repair. “Always double-check that the positive side is facing up.”
Preventing Future Key Fob Issues
Taking a few simple precautions can help prolong the life of your key fob battery and prevent future issues. Avoid exposing your key fob to extreme temperatures or moisture. Also, try not to drop it frequently, as this can damage the internal components.
Key Fob Programming and Remote Start Issues
While replacing the battery usually doesn’t require reprogramming, some situations, like replacing a lost or damaged fob, might necessitate programming. This typically involves a specific procedure outlined in your owner’s manual or can be done by a Subaru dealership. Remote start issues can also sometimes stem from a weak key fob battery. Replacing the battery is a good first step in troubleshooting these problems.
“Regular maintenance is key,” advises Jane Doe, Lead Technician at Doe’s Auto Solutions. “Just like your car battery, your key fob battery needs to be replaced periodically.”
Conclusion
Replacing your Subaru key fob battery is a quick and easy process that anyone can do. By following the steps outlined in this guide, you can avoid the inconvenience and potential costs associated with a dead key fob. Remember to keep a spare battery on hand, just in case!
