Owning a 2004 Subaru is a joy, but like any car, it has its quirks. One common issue owners face is a dying key fob battery. If your 2004 Subaru key fob is acting up – locking and unlocking erratically or failing to respond altogether – chances are it’s time for a fresh battery. This comprehensive guide will walk you through everything you need to know about 2004 Subaru Key Fob Battery replacement, from identifying the correct battery type to troubleshooting common issues.
Identifying the Battery
Before you can replace your 2004 Subaru key fob battery, you need to know what you’re looking for. Subaru typically uses CR2032 batteries for their key fobs. This small, coin-shaped battery is widely available at most supermarkets, electronics stores, and auto parts shops.
Replacing the Battery: A Step-by-Step Guide
Replacing the battery in your 2004 Subaru key fob is a simple process that can be done in minutes. Here’s a step-by-step guide:
- Locate the key fob’s release button or notch: This is usually located on the back or side of the fob.
- Carefully pry open the key fob casing: You can use a flathead screwdriver or a coin to gently separate the two halves of the fob.
- Identify the battery: It should be sitting snugly in a designated compartment.
- Remove the old battery: Gently pry it out using your fingernail or a small, non-metal tool.
- Insert the new battery: Ensure the positive (+) side is facing upwards.
- Reassemble the key fob: Align the two halves of the casing and press them together until they snap shut.
Testing the New Battery
Once you’ve replaced the battery, it’s important to test the key fob to ensure it’s working properly. Try locking and unlocking your car doors, and then start the engine using the fob. If everything works as it should, you’re good to go!
Troubleshooting Tips
Sometimes, replacing the battery doesn’t solve the problem. Here are a few troubleshooting tips if your key fob is still acting up:
- Check the battery orientation: Ensure the new battery is inserted correctly with the positive (+) side facing up.
- Clean the battery contacts: Over time, these contacts can accumulate dirt and grime, hindering the connection. Use a cotton swab and a small amount of rubbing alcohol to clean them.
- Reprogram the key fob: In some cases, you may need to reprogram the key fob to your car after replacing the battery. Refer to your owner’s manual for specific instructions.
- Consult a professional: If you’ve tried all the above steps and your key fob is still not working, it’s best to consult a qualified Subaru technician or locksmith.
