How to Effortlessly Replace the Battery in Your Subaru Key Fob
The constant beeping of my car’s key fob was driving me insane. Every time I reached into my pocket, the incessant noise pierced the silence, reminding me of the dwindling battery that powered it. Determined to put an end to this annoyance, I decided to tackle the task of replacing the battery myself. Much to my surprise, it turned out to be a straightforward and time-saving endeavor.

Understanding Your Key Fob: A Journey Through Its Functionalities
At the heart of your Subaru key fob lies a clever circuit board that governs its numerous functions. These include:
- Locking and unlocking your vehicle
- Activating your alarm system
- Opening your trunk
- Remote starting your car (select models only)
To ensure seamless operation, this circuit board requires a constant supply of power, which is provided by a small coin-shaped battery. When the battery starts to weaken, the key fob’s performance suffers, ultimately leading to the dreaded beeping.
Navigating the Battery Replacement Process: A Step-by-Step Guide
**Step 1: Gather Your Essential Tools**
Before embarking on this automotive mission, ensure you possess a new CR2025 coin battery and a small flat-head screwdriver (for most Subaru models).
**Step 2: Unlocking the Key Fob’s Secrets**
Locate the small, often hidden release button on your key fob. Press it gently to release the mechanical key, which will simultaneously unlock the key fob’s casing.
**Step 3: Replacing the Battery: A Simple Swap**
Carefully pry open the two halves of the key fob’s casing, being mindful of any small springs or buttons that may dislodge. Once opened, you’ll spot the old battery nestled within. Gently remove it and replace it with the new CR2025 battery, ensuring correct polarity (positive side facing up).
