What You'll Need

Before we get started, let's make sure you have everything you need. Here is a simple list:

• A new CR2032 battery: This is the standard button battery for most Subaru key fobs.
• A small flathead screwdriver or a similar tool to pry open the fob.
• A soft cloth to prevent scratches.

That’s it! With these simple tools, you’re ready to tackle this easy DIY project. Now, let’s get into the step-by-step instructions.

Step-by-Step Guide to Replacing Your Key Fob Battery

Okay, let's get into the fun part! Here's how to replace that pesky dead battery in your 2017 Subaru Impreza key fob:

Step 1: Open the Key Fob

First, locate the small notch on the side of your key fob. This is where you'll insert your flathead screwdriver. Gently insert the screwdriver into the notch and twist. You might hear a click, and the fob should start to split open. If it doesn't open easily, try applying a bit more pressure, but be careful not to force it too hard, or you might damage the plastic casing. Patience is key here!

Step 2: Separate the Fob

Once you've got the fob started, carefully separate the two halves. You might need to run the screwdriver along the seam to fully split it open. Take your time and avoid using excessive force. The goal is to separate the two halves without breaking any of the internal components. Once open, you'll see the battery and the circuit board. Try not to touch the circuit board to avoid any accidental damage. We are almost there!

Step 3: Remove the Old Battery

Now, take a look at how the old battery is positioned. Usually, the positive side (+) is facing up, but it’s always good to double-check. Use your flathead screwdriver to gently pry the old battery out of its holder. Be careful not to scratch the surrounding components. Sometimes the battery is held in place pretty snugly, so a little finesse might be needed. Once the old battery is out, you're halfway there!

Step 4: Insert the New Battery

Grab your new CR2032 battery and make sure you orient it the same way the old battery was positioned. Place the new battery into the holder and press down gently until it clicks into place. Ensure it’s sitting securely and making good contact with the terminals. A proper connection is crucial for the fob to work correctly, so double-check that it’s snug and secure. This is where we breathe new life into our key fob!

Step 5: Reassemble the Key Fob

Alright, time to put everything back together! Align the two halves of the key fob and gently press them together until they snap shut. Make sure all the edges line up properly and that there are no gaps. You should hear a click as the two halves come together securely. If it doesn’t close easily, double-check that all the internal components are correctly positioned and that nothing is obstructing the closure. Once it’s snapped shut, give it a little squeeze to ensure it’s fully sealed. You're practically done!

Step 6: Test the Key Fob

Finally, the moment of truth! Test the key fob by pressing the buttons to lock and unlock your 2017 Subaru Impreza. If everything went smoothly, your car should respond immediately. If it doesn’t work right away, don’t panic! Double-check that the battery is correctly installed and that the fob is fully closed. Sometimes, a simple reseating of the battery can do the trick. If it still doesn’t work after a few tries, it might be worth consulting your Subaru owner's manual or contacting a local dealership for further assistance. But chances are, you’ve nailed it!

Choosing the Right Replacement Battery

When it comes to replacing your key fob battery, you want to make sure you’re getting the right one. Here’s what you need to know to choose the best replacement battery for your 2017 Subaru Impreza key fob.

Battery Type

The CR2032 battery is the standard for most Subaru key fobs, including the one for your 2017 Impreza. This is a 3-volt lithium coin cell battery. Using the correct type is crucial for ensuring proper function and longevity of your key fob. Always double-check the battery type before purchasing to avoid any compatibility issues. Trust me, grabbing the wrong battery is a rookie mistake!

Brand and Quality

While there are many brands out there, it's generally a good idea to go with a reputable brand known for producing quality batteries. Brands like Panasonic, Sony, and Duracell are reliable choices. These brands tend to offer better performance and a longer lifespan compared to cheaper, generic alternatives. Investing a few extra bucks in a good brand can save you the hassle of frequent replacements and ensure your key fob works reliably when you need it most. Plus, who doesn’t love a battery that just keeps going and going?

Expiration Date

Always check the expiration date on the battery before you buy it. Batteries lose their charge over time, so you want to make sure you’re getting one that’s as fresh as possible. Look for a battery with an expiration date that’s at least a few years out. This ensures that the battery will hold its charge until you need it. A fresh battery means a happy key fob, and a happy key fob means a happy you!

Where to Buy

You can find CR2032 batteries at most drugstores, supermarkets, and electronics stores. Online retailers like Amazon are also a great option, offering a wide selection and competitive prices. When buying online, be sure to check the seller’s reviews and ratings to ensure you’re getting a genuine product from a reputable source. Avoid buying from unknown or unverified sellers, as they may be selling counterfeit or low-quality batteries. Play it safe and stick with trusted retailers!

Tips for Key Fob Maintenance

Taking good care of your key fob can extend its lifespan and prevent common issues. Here are some handy tips to keep your 2017 Subaru Impreza key fob in top-notch condition.

Protect from Moisture

Moisture is the enemy of electronics, and your key fob is no exception. Avoid exposing your key fob to water, rain, or excessive humidity. If your key fob does get wet, dry it off immediately with a soft cloth and remove the battery to prevent corrosion. Consider using a small, waterproof case or pouch to protect your key fob from the elements, especially if you live in a rainy area. Keeping it dry is half the battle!

Avoid Extreme Temperatures

Extreme temperatures can also damage your key fob and shorten the battery life. Avoid leaving your key fob in direct sunlight or in a hot car for extended periods. High temperatures can cause the battery to drain faster and can also damage the internal components of the fob. Similarly, extremely cold temperatures can also affect battery performance. Try to keep your key fob in a cool, dry place whenever possible. Treat it like a delicate little gadget!

Keep Away from Strong Impacts

Dropping your key fob can cause serious damage to the internal components, including the battery and circuit board. Avoid dropping your key fob on hard surfaces, and try to keep it in a safe place where it won’t be accidentally knocked off. Consider using a key fob cover or case to provide extra protection against impacts. A little bit of cushioning can go a long way in preventing damage from accidental drops. Handle with care, folks!

Regular Cleaning

Over time, dirt, dust, and grime can accumulate on your key fob, which can affect its performance and appearance. Clean your key fob regularly with a soft, dry cloth to remove any dirt or debris. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic casing and internal components. A gentle wipe-down every now and then is all it takes to keep your key fob looking and functioning its best. A clean fob is a happy fob!

Battery Replacement Reminder

Keep track of when you replaced the battery in your key fob, and set a reminder to replace it again in about a year or two. This will help prevent unexpected battery failures and ensure that your key fob is always ready to go when you need it. You can use a calendar app, a note on your phone, or even a good old-fashioned sticky note to remind yourself. A little bit of proactive maintenance can save you a lot of headaches down the road. Stay ahead of the game!

Troubleshooting Common Issues

Even with a new battery, sometimes things don’t go as planned. Here are some common issues you might encounter and how to troubleshoot them.

Key Fob Not Working After Battery Replacement

If your key fob isn’t working after replacing the battery, the first thing to do is double-check that the battery is installed correctly. Make sure the positive (+) side is facing the right way and that the battery is securely seated in the holder. Also, ensure that the battery contacts are clean and free from corrosion. Sometimes, a simple reseating of the battery can resolve the issue. If that doesn’t work, try cleaning the battery contacts with a cotton swab dipped in rubbing alcohol. A clean connection is essential for proper function.

Key Fob Has Reduced Range

If your key fob has a reduced range, meaning you have to be closer to your car for it to work, it could be a sign of a weak battery. Even a brand new battery can sometimes be faulty, so it’s worth trying a different battery to see if that resolves the issue. Interference from other electronic devices can also affect the range of your key fob. Try moving away from potential sources of interference, such as cell phones, laptops, and other electronic gadgets. A simple change of location can sometimes make a big difference.

Key Fob Buttons Not Responding

If some or all of the buttons on your key fob aren’t responding, it could be due to dirt or debris interfering with the button contacts. Try cleaning the buttons with a soft, dry cloth to remove any visible dirt or grime. If that doesn’t work, you can try using a can of compressed air to blow out any debris that may be lodged inside the fob. Be gentle and avoid using excessive force, as this could damage the buttons or internal components. A little bit of cleaning can often restore proper function.

Key Fob Disassembling

So, there you have it! Replacing the battery in your 2017 Subaru Impreza key fob is super simple. By following these steps and tips, you'll be back in action in no time. Plus, a little maintenance can keep your fob working like a charm for years to come. Keep your battery fresh, protect it from the elements, and handle it with care. You got this!
