Replacing Battery in Subaru Key Fob: A Quick Guide

A dead key fob battery can be a major inconvenience, leaving you stranded and unable to access your Subaru. Luckily, replacing the battery in your Subaru key fob is a simple task that you can do yourself in minutes. This guide will walk you through the process step-by-step.

Identifying Your Subaru Key Fob Type

Before you begin, you need to determine which type of key fob your Subaru uses. Subaru typically uses two main types of key fobs:

  • Standard Key Fob: This type has a flip-out key and a separate button panel for locking/unlocking the doors and panic function.
  • Keyless Access Fob (Smart Key): This type is typically thicker and may not have a visible flip-out key. It allows for keyless entry and push-button start.

The process for replacing the battery is slightly different for each type.

What You’ll Need

  • A small flat-head screwdriver
  • A new CR2032 battery (This is the most common battery type for Subaru key fobs. However, you should check your owner’s manual or the existing battery to confirm the correct type).

Replacing the Battery in a Standard Subaru Key Fob

  1. Locate the release button: On the back of the fob, find a small, indented button.
  2. Release the key: Press the release button and gently pull the flip-out key from the fob.
  3. Open the fob: Use the flat-head screwdriver to carefully pry open the fob casing. There’s usually a small notch where you can insert the screwdriver.
  4. Remove the old battery: Gently pry out the old battery, taking note of its orientation.
  5. Insert the new battery: Insert the new battery with the positive (+) side facing up.
  6. Reassemble the fob: Align the two halves of the fob casing and press them together until they snap shut.
  7. Reinsert the key: Slide the flip-out key back into its slot until you hear a click.

Replacing the Battery in a Subaru Keyless Access (Smart Key) Fob

  1. Locate the release notch: Look for a small notch on the edge of the fob.
  2. Open the fob: Insert the flat-head screwdriver into the notch and gently twist to separate the two halves of the fob casing.
  3. Remove the old battery: Carefully pry out the old battery, paying attention to its orientation.
  4. Insert the new battery: Place the new battery in the same orientation as the old one, with the positive (+) side facing up.
  5. Reassemble the fob: Align the two halves of the fob casing and press them together until they snap shut.

Testing Your New Key Fob Battery

After replacing the battery, test all the buttons on your key fob to ensure it’s working properly. If your Subaru still doesn’t respond to the key fob, there might be a different issue, and you may need to consult your owner’s manual or contact a qualified automotive technician.

Tips and Warnings

  • Handle the battery with care: Avoid touching the flat surfaces of the new battery, as this can reduce its lifespan.
  • Dispose of the old battery properly: CR2032 batteries contain lithium and should be disposed of according to local regulations.
  • Don’t force anything: If you encounter resistance when opening or closing the fob, double-check that you’re using the correct procedure and tools.
  • Consider professional help: If you’re uncomfortable performing these steps, a Subaru dealership or qualified automotive locksmith can replace the battery for you.
