Is your Honda CRV key fob starting to act up? Perhaps you’ve noticed the range is decreasing, or maybe it’s completely stopped working. Before you rush to the dealership and spend unnecessary money, the solution might be as simple as replacing the battery. The good news is, changing the battery in your Honda CRV key fob is a straightforward process that you can easily do yourself in just a few minutes, without needing any special tools or technical expertise. And importantly, you won’t need to reprogram your key fob after a battery replacement, as long as you follow these simple instructions.
To ensure a smooth and successful battery replacement for your Honda CRV key fob, let’s walk through the process step-by-step.
What You’ll Need
Before you begin, gather these few essential items:
- A new CR2032 battery: This is the standard button battery size for most Honda CRV key fobs. You can find these easily at drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or a coin: This will be used to gently pry open the key fob case. A small coin, like a penny or dime, can also work effectively and minimize the risk of scratching the fob.
- A soft cloth (optional): To protect the key fob casing from scratches during the opening process.
Step-by-Step Guide to Replacing Your Battery
Now, let’s get to the battery replacement itself. Follow these steps carefully:
-
Locate the Notch to Open the Fob: Examine your Honda CRV key fob closely. You should find a small notch or slot on the side or bottom of the fob casing. This is where you’ll insert your screwdriver or coin to begin opening it.
-
Gently Pry Open the Key Fob: Using your flathead screwdriver or coin, carefully insert the edge into the notch. Apply gentle pressure and twist slightly to begin separating the two halves of the key fob. Avoid using excessive force, as you could damage the casing. Work your way around the seam if needed, gently prying until the case splits open.

Access the Battery Compartment: Once the key fob is open, you’ll see the internal components and the battery. The battery is usually located in a small compartment and might be held in place by a small clip or simply pressure.
-
Remove the Old Battery: Take note of the battery’s orientation – specifically, the positive (+) and negative (-) sides. This is crucial for installing the new battery correctly. Gently remove the old CR2032 battery. You may be able to pry it out with your fingertip or use the edge of your screwdriver if it’s snug.
-
Install the New Battery: Take your new CR2032 battery and install it into the compartment, ensuring that the polarity (+ and -) is the same as the old battery you just removed. One side of the battery will usually have a “+” sign, indicating the positive terminal. Make sure this side is facing the correct direction as indicated in the battery compartment.

Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap securely closed. Ensure there are no gaps and the case is fully sealed.
Troubleshooting Tips
If you’ve replaced the battery and your key fob is still not working, consider these troubleshooting steps:
-
Verify Battery Quality and Polarity: Double-check that your new CR2032 battery is indeed new and has sufficient voltage. A brand new CR2032 battery should read around 3.3-3.4 volts using a voltmeter. Also, re-confirm that you installed the battery with the correct polarity (+ and – sides oriented properly). Make sure to remove any plastic protective film that sometimes comes on new batteries, as this can prevent proper contact.
-
Inspect for Button Displacement: When reassembling the key fob, ensure that none of the buttons have been accidentally dislodged. Sometimes, careless handling while the fob is open can cause the buttons to shift, preventing them from making proper contact when pressed.
-
Replace Battery in Both Fobs: As a best practice, if you have two key fobs for your Honda CRV, it’s advisable to replace the battery in both at the same time. This helps maintain synchronized battery life for both fobs and prevents you from having to replace the battery in the second fob a short time later.
-
Take Your Time: Rushing through the battery replacement process can lead to mistakes. Take your time and be gentle throughout each step to avoid damaging the key fob or its components.
Conclusion
Replacing the battery in your Honda CRV key fob is a simple maintenance task that any owner can accomplish. By following these steps and taking a little care, you can restore your key fob’s functionality and avoid unnecessary trips to the mechanic. Enjoy the convenience of a fully working key fob once again!
