How to Replace the Battery in Subaru Key Fob

Replacing the battery in your Subaru key fob is a quick and easy process that can save you time and money. A dead key fob battery can leave you stranded, so knowing how to change it yourself is a valuable skill. This guide will walk you through the steps involved in replacing the battery in various Subaru key fob models.

Understanding Your Subaru Key Fob

Subaru key fobs, like those in many modern vehicles, are powered by small batteries. Over time, these batteries deplete, and the key fob’s range and responsiveness diminish. Eventually, the battery dies completely, rendering the key fob useless. Recognizing the signs of a dying battery is crucial. These can include needing to be closer to your car for the key fob to work, intermittent functionality, or the key fob not working at all.

Gathering the Necessary Tools

Before starting the battery replacement process, gather the necessary tools. You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing. You’ll also need a replacement battery. The most common battery type used in Subaru key fobs is the CR2032. These are readily available at most electronics stores, pharmacies, and online retailers. Having a spare battery on hand is always a good idea. 2017 subaru key fob battery replacement demonstrates the tools and steps clearly.

Step-by-Step Guide: How to Replace the Battery in Subaru Key Fob

While specific steps may vary slightly depending on the model year and type of Subaru key fob, the general process remains similar:

Locate the release button or slot: Most Subaru key fobs have a small release button or slot on the side or back. This button releases the emergency key, which often hides the battery compartment.
Remove the emergency key: Press the release button and slide out the emergency key. Be careful not to lose the key.
Open the key fob casing: Use the flat-head screwdriver to gently pry open the key fob casing at the seam where the two halves join. Be careful not to damage the casing.
Remove the old battery: Identify the old CR2032 battery and carefully remove it. You may need to use your screwdriver to gently pry the battery out.
Install the new battery: Insert the new CR2032 battery, ensuring the positive (+) side is facing up, just as the old battery was positioned.
Close the key fob casing: Align the two halves of the key fob casing and press them together until they snap shut.
Reinsert the emergency key: Slide the emergency key back into its slot.
Test the key fob: Try locking and unlocking your car with the key fob to ensure the new battery is working correctly.
