A dead key fob battery can be a major inconvenience, leaving you stranded and unable to start your Subaru. While it might seem intimidating, replacing the battery in your Subaru key fob is actually a quick and straightforward process that you can easily do yourself. This comprehensive guide will walk you through every step, ensuring you’re back on the road in no time.
Understanding Your Subaru Key Fob
Before we dive into the replacement process, it’s helpful to understand the two main types of Subaru key fobs:
- Traditional Key Fob: This type features a physical key blade that folds into the fob.
- Keyless Entry Fob: Also known as a smart key or proximity key, this fob doesn’t have a visible key blade and allows you to unlock and start your car without taking it out of your pocket or purse.
Regardless of the type you have, the battery replacement process is generally very similar.
What You’ll Need
Gather the following items before you begin:
- A new CR2032 battery: This is the most common type of battery used in Subaru key fobs.
- A small flat-head screwdriver: This will help you pry open the key fob casing.
- Optional: A small container or tray: This will help keep the small parts organized during the process.
Step-by-Step Guide to Replacing Your Subaru Key Fob Battery
Follow these steps to replace the battery in your Subaru key fob:
-
Locate the release button or notch: Examine your key fob for a small button or notch on the back or side. This is usually located near the key ring hole.
-
Release the key blade (if applicable): If your key fob has a physical key blade, press the release button and carefully slide the blade out of the fob.
-
Separate the fob halves: Gently insert the flat-head screwdriver into the notch or beside the release button. Carefully pry open the fob casing. You may hear a slight click as the halves separate.
-
Identify and remove the old battery: Inside the fob, you’ll see the battery. Note its orientation (positive (+) side up or down). Carefully remove the battery, using the screwdriver to lift it out if necessary.
-
Install the new battery: Place the new CR2032 battery in the fob, ensuring it’s in the same orientation as the old battery.
-
Reassemble the key fob: Align the halves of the fob and press them together firmly until you hear them snap back into place.
-
Reinsert the key blade (if applicable): Slide the key blade back into the fob until it locks into position.
-
Test the key fob: Ensure your Subaru responds to the key fob by locking and unlocking the doors or using the remote start feature.
Troubleshooting Tips
If your key fob still isn’t working after replacing the battery, try these troubleshooting tips:
-
Check the battery orientation: Make sure the new battery is installed with the positive (+) side facing the correct direction.
-
Clean the battery contacts: Over time, the battery contacts inside the fob can become corroded. Use a cotton swab dipped in rubbing alcohol to gently clean the contacts.
-
Reprogram your key fob: In some cases, you may need to reprogram your key fob after replacing the battery. Refer to your Subaru owner’s manual for specific instructions as the procedure can vary by model and year.
-
Consult a professional: If you’ve tried all the above steps and your key fob is still not working, it’s best to consult with a qualified Subaru technician or automotive locksmith for further assistance. They can diagnose the issue and provide a solution, which might involve replacing the entire key fob if necessary.

The lifespan of a key fob battery can vary depending on usage and environmental factors. However, most Subaru key fob batteries last between 3 to 5 years. It’s a good idea to proactively replace your key fob battery every few years to avoid any unexpected inconveniences.
