How to Replace Battery in Subaru Key Fob

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to unlock your Subaru. Fortunately, replacing the battery is a quick and easy task that can be done at home with just a few tools. This comprehensive guide will walk you through the process step-by-step, ensuring you’re back on the road in no time.

Identifying Your Subaru Key Fob

Subaru offers various key fob designs across its model lineup. Before replacing the battery, it’s crucial to identify your specific key fob type. This will help determine the correct battery size and replacement procedure. Refer to your owner’s manual or consult online resources if you’re unsure about your Subaru key fob model.

Gathering the Necessary Tools

To replace the battery in your Subaru key fob, you’ll need a few basic tools:

  • Small flat-head screwdriver: This will be used to pry open the key fob casing.
  • New battery: The battery type varies depending on the key fob model. Refer to your owner’s manual or look for the battery type printed on the existing battery. Common types include CR2025 or CR2032.
  • Optional: Small plastic pry tool: This can be helpful for gently separating the key fob halves without scratching the surface.

Step-by-Step Battery Replacement Guide

Once you have gathered the necessary tools and a new battery, follow these steps to replace the battery in your Subaru key fob:

  1. Locate the key release button: On the back of your Subaru key fob, find the small button or switch that releases the physical key.
  2. Release the physical key: Press the key release button and gently slide out the physical key from the fob.
  3. Identify the seam: With the physical key removed, examine the edges of your Subaru key fob. Look for a small seam or indentation that indicates where the two halves of the casing connect.
  4. Gently pry open the casing: Insert the tip of your flat-head screwdriver (or plastic pry tool) into the seam. Carefully apply gentle pressure to pry open the casing slightly. Avoid using excessive force, as this may damage the key fob.
  5. Separate the key fob halves: Once the casing is slightly open, you can use your fingers or the pry tool to carefully separate the two halves. Be cautious not to touch any internal components.
  6. Locate and remove the old battery: Inside the key fob, you’ll find the battery. Note the position and orientation of the battery. Use your fingernail or the edge of the screwdriver to gently pry out the old battery.
  7. Insert the new battery: Align the positive (+) side of the new battery with the corresponding marking inside the key fob. Carefully press the battery into place until it sits securely.
  8. Reassemble the key fob: Align the two halves of the casing and gently press them together until you hear a click, indicating they are securely closed.
  9. Reinsert the physical key: Slide the physical key back into its slot on the key fob until it locks into place.

Testing the New Battery

After replacing the battery, test the key fob by pressing any button. If the fob functions correctly, the battery replacement was successful. If the fob still doesn’t work, double-check that the new battery is properly installed and that the battery contacts are clean.

Common Issues and Troubleshooting

While replacing the battery in your Subaru key fob is generally straightforward, you might encounter a few issues:

  • Key fob still doesn’t work: If the key fob remains unresponsive after replacing the battery, try cleaning the battery contacts inside the fob with a cotton swab and rubbing alcohol. Ensure the new battery is not faulty.
  • Key fob works intermittently: This could indicate a loose connection. Ensure the battery is properly seated and the key fob halves are tightly closed.
  • Damaged key fob: If you accidentally damage your key fob during the battery replacement, contact your local Subaru dealership or an authorized locksmith for assistance.

Importance of Regular Battery Replacement

Just like any other battery, your Subaru key fob battery has a limited lifespan. Replacing the battery regularly ensures your key fob remains functional, preventing inconvenient lockouts and potential security risks.

Seeking Professional Assistance

While this guide provides comprehensive instructions for replacing the battery in your Subaru key fob, if you’re uncomfortable performing this task yourself, you can always seek professional assistance from your local Subaru dealership or a qualified automotive locksmith.

Replacing the battery in your Subaru key fob is a simple yet essential maintenance task that can save you time, money, and potential headaches. By following these steps and taking the necessary precautions, you can ensure your Subaru key fob remains functional for years to come.
