Understanding Your Subaru Ascent Key Fob

Before we dive into the battery replacement process, let’s familiarize ourselves with the Subaru Ascent key fob. It’s a compact, sleek device that houses a small battery, a transmitter, and a receiver. The battery provides the power needed for the fob to send and receive signals. When the battery depletes, the fob’s range decreases, and eventually, it will stop working altogether.

Tools You’ll Need

To change the battery in your Subaru Ascent key fob, you’ll need the following:

• A small flathead screwdriver: This will be used to pry open the key fob casing.
• A replacement CR2032 battery: This is the standard battery type used in Subaru Ascent key fobs. You can purchase these at most electronics stores or online retailers.

Step-by-Step Guide to Changing the Key Fob Battery

Now, let’s get started with the battery replacement process:

1. Locate the Key Fob Release Button: On the side or back of your Subaru Ascent key fob, you’ll find a small release button. This button is usually hidden within a groove or under a small flap.

2. Pry Open the Key Fob: Using your flathead screwdriver, carefully insert it into the groove or under the flap where the release button is located. Gently pry open the key fob casing, separating the two halves.

3. Remove the Old Battery: Inside the key fob, you’ll see the old battery. It’s typically held in place by a spring or a small piece of plastic. Gently remove the old battery.

4. Insert the New Battery: Take your new CR2032 battery and ensure the positive (+) side is facing up. Carefully insert the new battery into the battery compartment. Make sure it sits securely in place.

5. Close the Key Fob: Once the new battery is in place, align the two halves of the key fob and gently press them together. The key fob should snap shut securely.

Tips for Extending Battery Life

Once you’ve replaced the battery, it’s a good idea to follow these tips to extend its lifespan:

• Avoid Extreme Temperatures: Extreme heat or cold can quickly drain the battery. Store your key fob in a cool, dry place when not in use.
• Minimize Button Presses: Every time you press a button on your key fob, it consumes battery power. Try to use the key fob sparingly and avoid unnecessary presses.
• Keep the Key Fob Clean: Dust and dirt can accumulate on the key fob and interfere with its functionality. Clean the key fob regularly with a soft cloth to ensure optimal performance.

What to Do if the Key Fob Still Doesn’t Work

If you’ve followed these steps and your key fob still doesn’t work, there could be a few other issues:

• Damaged Key Fob: Your key fob might be physically damaged, preventing it from transmitting signals.
• Dead Battery: Even though you’ve replaced the battery, it could be faulty. Try using a different CR2032 battery.
• Programming Issue: The key fob might need to be reprogrammed to your vehicle. Consult your Subaru dealership or a qualified mechanic for assistance.

While changing the battery is a common fix for a malfunctioning key fob, it’s essential to understand other potential issues that might arise.

• Key Fob Range: The range of your key fob can be affected by various factors, including the presence of electronic interference, the age of the key fob, and even the weather conditions. If you experience a significantly reduced range, consider having your key fob checked by a Subaru technician.
