What Battery Goes in a Subaru Key Fob?

If you’re a Subaru owner, you know that a working key fob is essential. It locks and unlocks your car, pops the trunk, and even starts the engine remotely. But what happens when your key fob battery dies? Don’t panic! Finding the right replacement is quick and easy. This guide will walk you through everything you need to know about Subaru key fob batteries, from identifying the correct type to replacing it yourself.

Which Battery Do I Need for My Subaru Key Fob?

Subaru key fobs typically use small, coin-shaped batteries. The most common type is the CR2032, a 3-volt lithium battery. However, some models may use different batteries, like the CR2025.

To be absolutely sure you’re getting the right battery, here’s what you can do:

• Check your owner’s manual: Your Subaru owner’s manual will list the correct battery type for your specific key fob.
• Look for markings on the battery itself: If you can open your key fob and access the old battery, it should have the battery type printed on it (e.g., CR2032).
• Consult a Subaru dealership or a reputable online auto parts retailer: Provide your car’s year, make, and model, and they can help you identify the correct battery.

How Do I Change the Battery in My Subaru Key Fob?

Replacing your Subaru key fob battery is a simple DIY task. Here’s a step-by-step guide:

1. Locate the release button or notch on your key fob. This is usually on the back or side.
2. Use a small flathead screwdriver or a coin to gently pry open the key fob. Be careful not to damage the casing.
3. Identify the old battery and note its position.
4. Carefully remove the old battery. You can use your fingernail or the tip of the screwdriver.
5. Insert the new battery, making sure the positive (+) side faces up. This will be indicated on the battery itself and often inside the key fob compartment.
6. Align the key fob halves and press them firmly together until you hear a click.

Congratulations! You’ve successfully replaced your Subaru key fob battery. Test the buttons to make sure everything is working correctly.

Common Subaru Key Fob Battery Issues (and How to Fix Them)

Sometimes, replacing the battery doesn’t solve the problem. Here are some other common key fob issues and what you can do:

• Key fob needs reprogramming: After a battery replacement, your key fob might need to be reprogrammed to your Subaru. Refer to your owner’s manual for instructions, or contact a dealership.
• Weak signal: If your key fob only works intermittently or at a very short range, the battery might be low, or there could be interference from other electronic devices. Try replacing the battery first.
• Damaged key fob: Physical damage, like dropping the key fob in water, can affect its functionality. If you suspect internal damage, it’s best to contact a dealership for repair or replacement.

Keep Your Subaru Key Fob Working Smoothly

• Don’t let your key fob battery die completely. A dying battery can lead to inconvenient lockouts and other issues.
• Avoid exposing your key fob to extreme temperatures as this can shorten battery life.
• Handle your key fob with care to prevent physical damage that could affect the battery compartment.

Knowing how to replace your Subaru Key Fob battery empowers you to stay in control and avoid unexpected disruptions. If you’re ever unsure about a procedure, consult your owner’s manual or reach out to a Subaru dealership for assistance.
