Is your 2022 Subaru key fob not working as reliably as it used to? Before you panic, the most likely culprit is a dead battery. Replacing the battery in your Subaru key fob is a straightforward task you can easily handle at home. This guide will walk you through the process, ensuring you can quickly regain full access to your vehicle.
Identifying Your Subaru Key Fob Type
Subaru utilizes a few different key fob designs, and knowing which one you have is the first step in replacing the battery. While the 2022 Subaru model year primarily uses the bulging rectangle shape, it’s always best to confirm. Check your owner’s manual if you’re uncertain about your key fob style. The battery replacement process is similar across models, but the battery type itself will vary.
There are generally three main types of Subaru key fobs you might encounter:
- Bulging Rectangle Shape: This is common for newer Subaru models, including many 2022 vehicles. It typically requires a CR2032 battery.
- Teardrop Shape: An older design, this fob is less common in 2022 models but might still be in use. It uses a 2025 battery.
- Exposed Metal Key with Buttons: This older style features a visible metal key and requires a CR 1620 battery. It also has an inner casing that needs to be opened.
Once you’ve identified your key fob type, you’ll know the correct battery you need for replacement. You can find these batteries at most drugstores, supermarkets, and online retailers.
Step-by-Step Subaru Key Fob Battery Replacement
Regardless of your specific 2022 Subaru key fob, the battery replacement process follows similar steps. Here’s a breakdown for each type:
Replacing the Battery in a Bulging Rectangle Subaru Key Fob (2032 Battery)
This guide is relevant for many 2022 Subaru models using the rectangular key fob.
- Remove the Emergency Key: Locate the small silver tab on the back of your key fob. Press and hold this tab to release and remove the metal emergency key. Set the key aside in a safe place.
- Open the Key Fob Casing: Carefully inspect the fob for a seam running along its edge. This is where you’ll need to pry it open. You can use your fingernail or a flathead screwdriver. If using a screwdriver, insert it gently into the seam and twist to separate the two halves of the fob. Be careful not to apply excessive force, which could damage the casing.
- Locate the Battery: Once open, you’ll see the internal components of the key fob. The round, flat key fob battery will be visible, either on top of or underneath the transmitter circuit board, depending on how the fob opened.
- Replace the Old Battery: Gently release the old battery. In some cases, there might be a small clip holding it in place. Note the orientation of the battery (positive side up) before removing it. Take your new CR2032 battery and place it in the same position, ensuring the correct side is facing upwards. Avoid touching the flat surfaces of the new battery with your fingers as much as possible; handle it by the edges to prevent transferring oils that can reduce battery life.
- Reassemble the Key Fob: Carefully snap the two halves of the key fob casing back together. You should hear or feel them click into place. Ensure the casing is fully closed with no gaps.
- Re-insert the Emergency Key: Slide the metal emergency key back into its slot until it clicks and is securely held in place.
Replacing the Battery in a Teardrop Shape Subaru Key Fob (2025 Battery)
If your 2022 Subaru (or older model) uses a teardrop-shaped fob, the process is very similar.
- Open the Key Fob Casing: The teardrop fob doesn’t have a separate emergency key to remove. Locate the seam on the fob and use your fingernail or a flathead screwdriver to carefully pry it open, just like with the rectangular fob.
- Locate and Replace the Battery: Follow steps 3 and 4 from the rectangular fob instructions, but ensure you are using a 2025 battery instead of a 2032.
- Reassemble the Key Fob: Snap the two halves of the teardrop fob back together securely.
Replacing the Battery in an Exposed Metal Key Subaru Key Fob (CR 1620 Battery)
For the oldest style of Subaru key fob with a constantly exposed metal key:
- Open the Outer Casing: This process is identical to opening the bulging rectangle or teardrop fobs. Pry open the main casing using the seam.
- Open the Inner Casing: Inside the outer casing, you’ll find a second, smaller casing that houses the battery. This inner casing will have small tabs. Press these tabs to release and open the inner casing.
- Locate and Replace the Battery: Remove the old CR 1620 battery and replace it with a new one, ensuring the correct orientation (positive side up).
- Reassemble Both Casings: Close the inner casing first, making sure it clicks shut. Then, place the inner casing back inside the outer casing and snap the outer casing closed.
What If a New Battery Doesn’t Solve the Problem?
If you’ve replaced your 2022 Subaru Key Fob Battery and it’s still not working, the issue might be more complex. In some cases, the key fob itself may need to be replaced, or it might require reprogramming.
-
Key Fob Replacement and Programming: For security reasons, purchasing and programming a new key fob often needs to be done through an authorized Subaru dealership. If you suspect your fob is faulty, contact your local Subaru dealer. They can diagnose the issue and provide a replacement and programming service. Newer Subaru models, especially those with the bulging rectangular fob, typically require dealership programming.
-
DIY Programming for Older Models: While not always applicable to 2022 models, some older Subaru key fobs can be programmed at home. The original article provided a set of steps for this process. However, it’s crucial to understand that these DIY programming methods may not work for all models, particularly newer ones with advanced security features. Always consult your owner’s manual or a Subaru dealership for the most accurate programming information for your specific 2022 Subaru.
