Is your 2019 Honda CRV key fob not working as reliably as it used to? A common culprit is a low battery. The good news is, replacing the battery in your Honda CRV key fob is a straightforward process that you can easily do yourself without needing to reprogram anything. This guide will walk you through the steps and ensure you get back to using your remote functions without a hitch.
What You Need to Know About Your Key Fob Battery
The battery you’ll need for your 2019 Honda CRV key fob is a CR2032 battery. This is a common and readily available button cell battery. Before you begin, it’s wise to ensure you have a fresh CR2032 battery on hand.
Step-by-Step Battery Replacement for Your 2019 Honda CRV Key Fob
Replacing the battery is a simple task, just follow these steps carefully:
-
Prepare Your Workspace: Find a clean, flat surface to work on. It’s recommended to place your key fob button side down to prevent accidentally dislodging any buttons.
-
Open the Key Fob: Refer to your owner’s manual for the specific instructions on opening your 2019 Honda CRV key fob. Typically, this involves releasing a small latch or pressing a button to separate the two halves of the fob.
-
Identify and Remove the Old Battery: Once open, you’ll see the CR2032 battery. Take note of the battery’s orientation (+ and – sides). Gently remove the old battery.
-
Install the New Battery: Insert the new CR2032 battery, ensuring the polarity is correct (match the + and – signs). Make sure the battery is fully seated and making good contact.
-
Reassemble the Key Fob: Carefully snap the two halves of the key fob back together until they are securely closed.
Troubleshooting and Important Checks
After replacing the battery, if your key fob still isn’t working, consider these points:
-
Battery Quality: Are you certain the new CR2032 battery is good? A brand new CR2032 battery should measure around 3.3-3.4 volts DC using a voltmeter. Low battery warnings often appear when the voltage drops to approximately 3.1 volts.
-
Polarity and Contact: Double-check that you installed the battery with the correct polarity and that it’s making solid contact on both the positive and negative terminals.
-
Protective Plastic: Inspect the new battery for any clear plastic film on either side. If present, remove it as it can block electrical contact.
-
Button Check: Handle the open fob with care. Ensure none of the buttons were accidentally knocked loose during the battery replacement.
Pro Tip: Replace Batteries in Both Key Fobs
To maintain consistent performance and avoid future issues, it’s a good practice to replace the battery in both of your 2019 Honda CRV key fobs at the same time. This keeps their battery life synchronized and prevents you from having to repeat the process again soon for your second fob.
By following these steps, you should be able to easily replace the battery in your 2019 Honda CRV key fob and restore its functionality.
