Changing Key Fob Battery Subaru: A Comprehensive Guide

Changing your Subaru key fob battery is a simple task that can save you time and money. This guide will walk you through the process, troubleshoot common issues, and answer frequently asked questions, whether you’re a car owner, a mechanic, or an automotive technician.

Understanding Your Subaru Key Fob

There are several types of Subaru key fobs, each with slightly different battery replacement procedures. Knowing your key fob type is the first step to a successful battery change. Older models may have a traditional key with a separate fob, while newer models might feature a smart key or proximity key. Regardless of the type, the underlying principle remains the same: access the battery compartment, replace the old battery with a new one, and reassemble the fob.

Identifying Your Key Fob Type

Traditional Key with Separate Fob: This type usually has a physical key blade that folds into the fob. The battery compartment is typically accessed by sliding or prying open a small cover.
Smart Key/Proximity Key: These keys allow keyless entry and push-button start. They often have a small emergency key blade hidden inside. The battery compartment access varies depending on the specific model.

While the specifics might vary slightly depending on the model year and key fob type, the general process for changing a Subaru key fob battery is as follows:

Gather Your Tools: You’ll need a small flat-head screwdriver or a similar tool to pry open the key fob casing, and a new CR2032 battery.
Locate the Battery Compartment: This is usually on the back or side of the fob. Refer to your owner’s manual for specific instructions for your model.
Open the Key Fob: Carefully insert the flat-head screwdriver into the designated slot or seam and gently pry open the casing. Be careful not to damage the plastic.
Remove the Old Battery: Once the casing is open, you should see the CR2032 battery. Gently pry it out using your screwdriver or fingernail.
Install the New Battery: Insert the new CR2032 battery, making sure the positive (+) side is facing up, just like the old battery.
Reassemble the Key Fob: Snap the two halves of the key fob casing back together. Ensure it closes securely.
