Is your 2019 Honda CRV key fob not working as reliably as it used to? A common culprit is a low battery. Fortunately, replacing the battery in your Honda CRV key fob is a straightforward process that you can easily do yourself at home, without needing to reprogram anything. This guide will walk you through each step to ensure a smooth and successful battery replacement.
Step-by-Step Guide to Replacing Your Key Fob Battery
Changing the battery in your 2019 Honda CRV key fob is a simple task, but attention to detail is key. Here’s how to do it:
What You’ll Need
Before you begin, gather these items:
- A new CR2032 battery. This is the standard battery type for most Honda key fobs and is readily available at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver or a similar thin tool. This will be used to gently pry open the key fob case.
- A soft cloth or surface. This will protect the key fob from scratches during the battery replacement process.
Steps to Replace the Battery
- Prepare your workspace: Find a clean, flat surface and lay down a soft cloth to prevent scratches on your key fob. Place your key fob button-side down on this surface.
- Locate the notch: Look for a small notch on the side of your key fob casing. This notch is usually located on the side opposite the key ring.
- Open the key fob: Insert the tip of your flathead screwdriver or thin tool into the notch. Gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid using excessive force to prevent damage to the casing.
- Access the battery: Once the case is open, you’ll see the circuit board and the battery. The CR2032 battery is usually held in place by a small clip or pressure.
- Remove the old battery: Carefully note the orientation of the old battery (+ side up or down) before removing it. Use your fingertip or the tip of the screwdriver to gently pry the old battery out of its housing.
- Install the new battery: Take your new CR2032 battery and install it in the same orientation as the old battery. Ensure it is securely placed in the battery compartment and making good contact.
- Reassemble the key fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap closed. Ensure there are no gaps and the case is securely sealed.
- Test your key fob: Press the buttons on your key fob to ensure it is working correctly. The indicator light on the fob should illuminate, and your Honda CRV should respond to the commands (locking, unlocking, panic button, etc.).
Troubleshooting Tips and Best Practices
If you encounter issues after replacing the battery, consider these points:
Battery Check
- Verify battery freshness: Ensure the new CR2032 battery is indeed new and not expired. A brand new CR2032 battery should have a voltage reading of around 3.3-3.4 volts. You can use a voltmeter to check this if you have one.
- Check battery polarity: Double-check that you installed the new battery with the correct polarity (+ and – sides oriented correctly, matching the original battery’s placement).
Proper Installation
- Ensure good contact: Make sure the battery is fully inserted into the battery holder and is making solid contact with both the positive and negative terminals within the key fob.
- Inspect for obstructions: Check for any debris or plastic coverings on the new battery that might be preventing proper contact. Some new batteries may have a protective plastic film that needs to be removed.
Handling Precautions
- Gentle handling: When opening the key fob, handle it carefully to avoid accidentally dislodging any internal components, especially the buttons. Always change the battery with the fob resting button side down to minimize the risk of disturbing the buttons.
- Avoid rushing: Take your time during the battery replacement process. Rushing can lead to mistakes or damage.
Best Practice Recommendation: To maintain consistent performance and avoid future surprises, it’s a good practice to replace the batteries in both of your Honda CRV key fobs at the same time. This ensures both fobs have fresh batteries and helps you avoid having to replace the battery in the second fob just a few months later.
By following these steps and tips, you can confidently change the battery in your 2019 Honda CRV key fob and keep it working reliably.
