Are you having trouble starting your Subaru? It could be that the battery in your key fob needs replacing. This can be a frustrating issue to deal with, especially if you're in a hurry. Fortunately, replacing your Subaru key battery is a quick and easy process that you can do yourself. In this article, we'll guide you through the steps to replace your Subaru key battery, so you can get back on the road in no time.

Step 1: Identify Your Key Fob

The first step in replacing your Subaru key battery is identifying which key fob you have. If you have more than one key fob, you'll need to replace the battery in each one separately. Look for a small button on the back of your key fob, which you can press to release the key blade. Once you've done this, you'll be able to see the battery compartment.

Step 2: Remove the Battery

To remove the old battery, use a small flathead screwdriver to gently pry open the battery compartment. Be careful not to damage the key fob or lose any small components inside. Once you've opened the compartment, you should be able to see the old battery. Use your fingers or a small pair of pliers to remove the battery from the compartment. Take note of the battery type, so you can purchase the correct replacement.

Step 3: Replace the Battery

Once you have your replacement battery, it's time to install it in your key fob. Make sure the battery is inserted with the correct polarity, as indicated by the markings inside the battery compartment. Gently press the battery into place, making sure it sits securely in the compartment. Once the battery is installed, snap the battery compartment cover back into place.

Step 4: Test Your Key Fob

Now that you've replaced the battery in your key fob, it's time to test it out. Press any button on the key fob to make sure it's working properly. If the key fob doesn't work, double-check that the battery is inserted correctly and that the battery compartment cover is securely in place. If you're still having issues, it may be time to replace your key fob entirely.

Tips for Maintaining Your Subaru Key Fob

Replacing your Subaru key battery is a quick and easy process, but there are a few things you can do to help extend the life of your key fob battery:

1. Keep Your Key Fob Clean

Dirt and grime can build up around the buttons on your key fob, which can prevent them from working properly. Use a soft cloth or toothbrush to clean your key fob regularly.

2. Use Your Key Fob Regularly

If you don't use your key fob regularly, the battery can drain faster than if you use it daily. Make sure to use your key fob at least once a week to help keep the battery charged.

Conclusion

Replacing the battery in your Subaru key fob is a simple task that you can do yourself. By following these easy steps, you can save yourself time and money by not having to take your key fob to a dealership or mechanic. Remember to keep your key fob clean and use it regularly to help extend the life of your battery. If you're still having issues with your key fob, it may be time to replace it entirely. With a little bit of maintenance, your Subaru key fob can last for years to come.
