Hey guys! Is your 2017 Honda Accord key fob starting to act up? Are you finding yourself having to get closer and closer to your car for it to unlock? Chances are, the battery in your remote is dying. Don't worry, it's a super common issue and thankfully, a pretty easy fix. This guide will walk you through everything you need to know about replacing the battery in your 2017 Honda Accord remote, from identifying the symptoms of a low battery to step-by-step instructions and even some helpful tips to keep your new battery going strong.

Recognizing the Signs of a Weak Key Fob Battery

Before you dive into replacing the battery, let's make sure that's actually the problem. Here are some telltale signs that your 2017 Honda Accord key fob battery is on its last legs:

• Reduced Range: This is the most common symptom. You'll notice you have to be much closer to your car than usual for the remote to work. What used to work from across the parking lot now requires you to be right next to the door.
• Intermittent Functionality: Sometimes it works, sometimes it doesn't. The buttons might be unresponsive one minute and then work fine the next. This erratic behavior is a classic sign of a dying battery.
• Dashboard Warning Light: Some Honda Accords have a warning light on the dashboard that illuminates when the key fob battery is low. Keep an eye out for this light, as it's a pretty direct indication of the issue.
• Difficulty Starting the Car: In some cases, a dead key fob battery can even prevent you from starting your car, especially if your car uses a push-button start. The car might not recognize the key, leaving you stranded. While this is not super common, it's good to be aware of.
• The Red Light on the Fob Doesn't Blink: When you press a button on your key fob, you should see a small red light illuminate. If you press the button and the light doesn't blink, that's a clear sign the battery is dead or dying. This is the easiest way to check.

If you're experiencing one or more of these symptoms, it's time to consider a battery replacement. Continuing to use a dying battery can lead to frustration and potential issues, especially if it dies completely at an inconvenient moment.

Gathering Your Tools and Supplies

Okay, so you've determined that your key fob battery needs replacing. Here’s what you’ll need to get the job done. The great news is that you probably already have these things lying around the house, so you will not need to do any special shopping.

• A New CR2032 Battery: This is the most common type of battery used in Honda key fobs. You can find these at most drugstores, grocery stores, and electronics stores. They're also readily available online. Make sure you get the right size – CR2032 is the key! It's also a good idea to buy a name-brand battery for longer life and better performance. Generic brands might save you a few cents, but they often don't last as long.
• A Small Flathead Screwdriver or Pry Tool: You'll need this to open the key fob casing. A small screwdriver works great, but you can also use a plastic pry tool designed for electronics. These plastic tools are less likely to scratch or damage the fob. If you're using a screwdriver, be extra careful not to apply too much force, as you could crack the plastic casing.
• A Soft Cloth or Towel: This is optional, but it's a good idea to have a soft cloth or towel on hand to protect the key fob from scratches while you're working on it. Place the fob on the cloth while you're disassembling it to prevent any accidental damage.
• Your 2017 Honda Accord Key Fob: Obviously, you can't replace the battery without the key fob itself! Make sure you have it handy and that you're working in a well-lit area. It’s also a good idea to have a small container to hold the screws or other small parts so you don’t lose them.

With these simple tools and supplies, you'll be well-equipped to tackle this easy DIY project. Remember to take your time and be gentle, and you'll have your key fob working like new in no time!

Step-by-Step Battery Replacement Guide

Alright, let's get down to business! Follow these simple steps to replace the battery in your 2017 Honda Accord key fob:

1. Locate the Notch or Seam: Examine your key fob closely. You'll find a small notch or seam along the edge of the casing. This is where you'll insert your screwdriver or pry tool to open the fob.
2. Insert and Twist (Gently): Carefully insert the tip of your flathead screwdriver or pry tool into the notch or seam. Gently twist the tool to pry the two halves of the key fob casing apart. Be patient and apply steady pressure. You might hear a small click as the casing begins to separate. Avoid using excessive force, as this could damage the plastic.
3. Separate the Casing: Once you've created a small opening, carefully work your way around the seam, gently prying the two halves of the casing apart. The casing might be held together by small clips, so you'll need to release these clips as you go. Take your time and be gentle. You don't want to break any of the clips.
4. Locate the Battery: With the casing open, you'll see the circuit board and the battery. The battery is usually held in place by a small clip or bracket.
5. Remove the Old Battery: Use your fingernail or the tip of your screwdriver to gently pry the old battery out of its holder. Pay attention to the orientation of the battery – the positive (+) side should be facing up. This is important for installing the new battery correctly.
6. Insert the New Battery: Take your new CR2032 battery and insert it into the holder, making sure the positive (+) side is facing up. Press down gently until the battery clicks into place.
7. Reassemble the Casing: Carefully align the two halves of the key fob casing and press them together until they snap back into place. Make sure all the clips are securely fastened and that there are no gaps or openings in the casing. If the casing doesn't snap together easily, double-check that the battery is properly seated and that there are no obstructions preventing the two halves from closing.
8. Test the Key Fob: Once the casing is reassembled, test the key fob to make sure it's working properly. Press the buttons to lock and unlock your car, and make sure the red light on the fob illuminates when you press a button. If the key fob doesn't work, double-check that the battery is installed correctly and that the casing is securely closed.

Congratulations! You've successfully replaced the battery in your 2017 Honda Accord key fob. Now you can enjoy the convenience of a fully functional remote once again!

Troubleshooting Common Issues

Even with careful execution, sometimes things don't go exactly as planned. Here are a few common issues you might encounter and how to troubleshoot them:

• Key Fob Still Doesn't Work: If the key fob still doesn't work after replacing the battery, the first thing to do is double-check the battery orientation. Make sure the positive (+) side is facing up. Also, ensure that the battery is securely seated in the holder and that the contacts are clean. If that doesn't work, try cleaning the battery contacts with a cotton swab dipped in rubbing alcohol. In rare cases, the key fob itself might be faulty, and you may need to consult a locksmith or Honda dealer.
• Casing Won't Close Properly: If you're having trouble getting the casing to close properly, make sure the battery is fully seated and that there are no obstructions preventing the two halves from coming together. Also, check the clips on the casing to make sure they're not damaged or broken. If a clip is broken, you might need to replace the entire key fob casing.
• Stripped Screws: If you're using a screwdriver to open the key fob and you accidentally strip the screws, try using a rubber band between the screwdriver and the screw head. This can sometimes provide enough extra grip to turn the screw. If that doesn't work, you might need to use a screw extractor tool.
• Lost Parts: It's easy to lose small parts when working on electronics. To prevent this, work in a well-lit area and use a small container to hold the screws and other small parts. If you do lose a part, you might be able to find a replacement at a hardware store or online.

By following these troubleshooting tips, you can overcome most common issues and get your key fob working like new.

Tips for Extending Battery Life

To keep your new key fob battery going strong for as long as possible, here are a few helpful tips:

• Avoid Extreme Temperatures: Extreme heat and cold can drain the battery. Avoid leaving your key fob in direct sunlight or in a freezing car.
• Keep it Dry: Moisture can damage the key fob and shorten the battery life. Keep your key fob away from water and other liquids.
• Store it Properly: When you're not using your key fob, store it in a cool, dry place away from direct sunlight and extreme temperatures.
• Replace the Battery Regularly: Even if your key fob seems to be working fine, it's a good idea to replace the battery every one to two years to prevent unexpected failure.
• Use Quality Batteries: Invest in name-brand batteries for longer life and better performance. Generic brands might save you a few cents, but they often don't last as long.

By following these simple tips, you can extend the life of your key fob battery and avoid the inconvenience of a dead remote.
