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 simple process that you can easily do yourself at home. This guide will walk you through the steps, ensuring you get your key fob back in top shape without needing a trip to the dealership for reprogramming.
The good news is that, as mentioned in your owner’s manual, replacing the battery is straightforward and does not require any reprogramming of your key fob. As long as you follow the correct procedure, your key fob should function perfectly after a battery swap.
Before you start, let’s cover the essentials and troubleshoot some common issues to ensure a smooth replacement.
Step-by-Step Battery Replacement for Your 2019 Honda CRV Key Fob
-
Identify the Correct Battery: Your 2019 Honda CRV key fob uses a CR2032 battery. Make sure you have a fresh CR2032 battery on hand before you begin. It’s a widely available and inexpensive battery.
-
Open the Key Fob: Consult your owner’s manual for the exact method to open your specific key fob. Generally, this involves locating a small release button or latch on the fob. You may need a small flathead screwdriver or a similar tool to gently pry the fob open. Be careful not to scratch or damage the fob casing.
-
Remove the Old Battery: Once the fob is open, you’ll see the battery. Take note of the battery polarity (+ and – sides) before removing the old battery. Gently remove the old battery.
-
Install the New Battery: Insert the new CR2032 battery, ensuring the polarity is correct. Double-check that the + and – sides of the battery are oriented correctly according to the markings in the key fob case.
-
Reassemble the Key Fob: Carefully close the key fob casing, ensuring it snaps securely back together.
Troubleshooting Tips and Best Practices
-
Verify New Battery Quality: Are you certain your new battery is actually good? A brand new CR2032 battery should register around 3.3-3.4 volts DC (VDC) when measured with a voltmeter. A “low battery” alert in your CRV often triggers when the fob battery voltage drops to approximately 3.1 VDC. Button batteries tend to decline sharply at the end of their life, which is why Honda CRVs are designed to warn you around this 3.1 VDC threshold.
-
Check Battery Installation: Take the fob apart again and meticulously re-examine everything. Re-install the battery after confirming it’s a good CR2032 battery. Ensure the battery is fully seated in its compartment and making solid contact on both the positive (+) and negative (-) terminals.
-
Handle with Care and Patience: Take your time during this process. Rushing can lead to mistakes and frustration. Work in a clean, well-lit area.
-
Remove Protective Plastic: Double-check your new battery for any protective plastic film on either side. Some batteries have this, and it must be removed for proper contact.
-
Button Side Down: Always perform battery changes with the key fob placed button side down on a flat, clean surface. This precaution helps prevent accidentally dislodging any buttons while the fob is open, which could potentially cause a button to become stuck in a pressed position, constantly sending signals to your vehicle. This is a common issue reported after fob battery replacements.
-
Replace Both Fob Batteries: It’s a good practice to replace the batteries in both of your key fobs at the same time. This keeps their battery life synchronized and prevents you from having to repeat the replacement process again in just a few months for your second key fob.
By following these steps and tips, you should be able to easily replace your 2019 Honda Crv Key Fob Battery and restore its reliable performance. Enjoy the convenience of your keyless entry and ignition once again!
