Changing the battery in your Subaru Crosstrek key fob is a simple DIY task that can be done in minutes. This guide will walk you through the process, ensuring you’re back on the road in no time.

Tools You’ll Need

Before diving into the battery change, gather the following tools:

• A small screwdriver: This is essential for opening the key fob casing.
• A new CR2032 battery: This is the standard battery used in Subaru Crosstrek key fobs. You can find these at most convenience stores, drugstores, or online retailers.

Identifying the Key Fob Battery

The battery compartment is typically located on the back of the key fob. Look for a small, circular recess on the back of the fob. You might see a small arrow pointing to this recess, indicating the battery compartment.

Opening the Key Fob Case

1. Locate the release tab: Carefully examine the edges of the key fob. You’ll find a small, narrow tab or groove. This is the release tab.
2. Insert the screwdriver: Insert the tip of your screwdriver into the release tab. Gently pry the key fob case open. Be careful not to force it, as you could damage the fob.
3. Separate the halves: Once you’ve pried the case open slightly, you should be able to separate the two halves of the key fob.

Replacing the Battery

1. Remove the old battery: The battery is usually held in place by a small spring clip. Gently remove the old battery from the compartment.
2. Insert the new battery: Take your new CR2032 battery and align the positive (+) side with the positive terminal in the battery compartment. Carefully push the battery into place.
3. Reassemble the key fob: Once the new battery is in place, align the two halves of the key fob and snap them back together. Make sure the case is securely closed.

Testing the New Battery

1. Unlock your car: Press the unlock button on your key fob to test if the new battery is working. If your car unlocks, you’ve successfully replaced the battery.

Tips for Extending Battery Life

• Avoid extreme temperatures: Extreme heat or cold can shorten the lifespan of your key fob battery. Store your key fob in a cool, dry place.
• Minimize button presses: Try to avoid unnecessary button presses on your key fob. This can help conserve battery life.
• Replace the battery regularly: Even if your key fob still works, it’s a good idea to replace the battery every year or two. This will help ensure your key fob is always functioning properly.
