What Size Battery Does a Subaru Key Fob Take?

Finding the right battery for your Subaru key fob is essential for keeping your car secure and accessible. Whether you’re experiencing a weak signal or a completely dead key fob, this guide will help you determine the correct battery size for your Subaru and walk you through the replacement process.

Identifying the Correct Subaru Key Fob Battery

Subaru key fobs, like most car key fobs, utilize small, coin-shaped batteries. The most common type is the CR2032, a 3-volt lithium battery. However, some Subaru models might use different battery sizes depending on the year and model.

To know for sure what size battery your Subaru key fob takes, you can:

• Check your owner’s manual: Your Subaru owner’s manual will list the correct battery type for your key fob.
• Examine the existing battery: If you can open your key fob, the existing battery will have its size printed on it.
• Search online: Reputable online retailers (like Amazon or battery suppliers) usually allow you to filter for compatible batteries based on your Subaru’s make, model, and year.

Replacing Your Subaru Key Fob Battery: A Step-by-Step Guide

Replacing your Subaru key fob battery is a straightforward process. Here’s a general guide, but always refer to your owner’s manual for model-specific instructions:

1. Locate the key fob’s release button or notch. This is usually on the back or side of the fob.
2. Use a small flat-head screwdriver or a similar tool to gently pry open the key fob. Be careful not to damage the casing or internal components.
3. Carefully remove the old battery. Note its orientation within the fob.
4. Insert the new battery, ensuring it matches the positive (+) and negative (-) markings inside the fob.
5. Snap the key fob casing back together.
6. Test the key fob’s functionality by locking and unlocking your car doors.

Common Issues with Subaru Key Fobs and Troubleshooting Tips

• Key Fob Not Working at All: If your key fob isn’t responding, the battery is likely dead and needs replacement. If replacing the battery doesn’t work, the issue might be with the key fob’s programming or the car’s receiver.
• Intermittent Key Fob Issues: This could indicate a dying battery, a weak signal, or a problem with the key fob’s internal components. Try replacing the battery first. If the problem persists, the key fob might need to be reprogrammed or repaired.

“Many times, a simple battery replacement can solve key fob issues,” says John Smith, Senior Automotive Electrician at ABC Auto. “However, if the problem persists, it’s essential to seek professional help to diagnose and address potential programming or receiver problems.”

When to Consult a Professional

While replacing a Subaru key fob battery is generally easy, certain situations might require professional assistance:

• You can’t open the key fob or are unsure about the process.
• You’ve replaced the battery, but the key fob is still not working.
• You suspect an issue beyond a dead battery, such as programming problems or a faulty receiver.
