Are you experiencing the dreaded “low battery” signal on your Subaru Forester key fob? It’s a common issue, and it’s a simple fix! Replacing the battery in your Subaru Forester key fob is a straightforward process that can be done in just a few minutes. This guide will walk you through the steps, so you can get your key fob working again in no time.

Why Does My Subaru Forester Key Fob Battery Die?

Key fob batteries are like any other battery – they have a limited lifespan. Over time, the battery’s chemical energy depletes, leading to a weakened signal and eventually, a completely dead fob.

Here are some factors that can contribute to a faster battery drain:

  • Frequent use: If you use your key fob often, the battery will deplete faster.
  • Extreme temperatures: Heat and cold can affect battery life, so storing your key fob in extreme temperatures can contribute to a faster drain.
  • Age: Like all batteries, key fob batteries have a limited shelf life. Even if you don’t use your key fob frequently, the battery will eventually die.

Tools You’ll Need

Before you begin, gather the following tools:

  • A small flathead screwdriver
  • A new CR2032 battery (This is the standard battery used in most Subaru Forester key fobs. You can find them at most electronics stores or online.)

Step-by-Step Guide to Replacing the Battery

1. Locate the Battery Compartment

  • On most Subaru Forester key fobs, the battery compartment is located on the back of the fob. You’ll usually find a small groove or seam that runs around the perimeter of the fob.
  • If your key fob has a different design, you may need to consult your owner’s manual to locate the battery compartment.

2. Open the Key Fob

  • Using your small flathead screwdriver, gently pry open the key fob along the seam. Be careful not to apply too much force, as you could damage the key fob.
  • The key fob should open like a clamshell, revealing the battery inside.

3. Remove the Old Battery

  • Carefully remove the old CR2032 battery from the key fob. Note the positive (+) and negative (-) sides of the battery.
  • Dispose of the old battery properly.

4. Insert the New Battery

  • Insert the new CR2032 battery into the key fob, making sure to align the positive (+) and negative (-) sides correctly.
  • If you’re unsure about the correct orientation, refer to the diagram inside the battery compartment or your owner’s manual.

5. Close the Key Fob

  • Gently snap the two halves of the key fob back together. Make sure they are securely closed.
  • Press firmly around the edges to ensure a good seal.

6. Test the Key Fob

  • Try locking and unlocking your car with the key fob. If it works, you’ve successfully replaced the battery.
  • If you’re still having trouble, double-check the battery orientation and ensure the key fob is properly closed.

Important Tips for Key Fob Battery Care

  • Use high-quality batteries: Choosing high-quality batteries can extend the life of your key fob.
  • Store your key fob properly: Avoid storing your key fob in extreme temperatures, as this can affect battery life.
  • Replace batteries promptly: Don’t wait until the key fob completely dies to replace the battery. Replacing it when you first notice the low battery signal can help prevent damage to the fob’s electronics.

What to Do If Your Key Fob Still Doesn’t Work

If you’ve successfully replaced the battery and your key fob still doesn’t work, there are a few other things to try:

  • Check the battery terminals: Make sure the battery terminals are clean and free of corrosion.
  • Reset the key fob: Some key fobs have a reset button. Consult your owner’s manual to see if your key fob has this feature.
  • Take your car to a Subaru dealer: If you’ve tried all of the above steps and your key fob still doesn’t work, you may need to take your car to a Subaru dealer for professional assistance.
