Is your 2018 Honda CR-V key fob not working as reliably as it used to? It might be time for a battery replacement. The good news is, changing the battery in your Honda CR-V key fob is a straightforward process that you can easily do yourself at home. This guide will walk you through the steps and ensure you get your key fob back in top working condition without needing to visit a dealership for reprogramming.
Before you begin, it’s important to confirm a few key things to ensure a smooth and successful battery replacement. First, are you certain the new battery you’re using is actually good? The correct battery type for your 2018 Honda CR-V key fob is a CR2032. It’s also crucial to install it with the correct polarity. If you’re unsure, it’s always a good idea to test the new CR2032 battery with a voltmeter before installation. A fresh CR2032 battery should register around 3.3 to 3.4 volts DC. Typically, your CR-V will display a low battery alert when the fob battery voltage drops to approximately 3.1 volts.
To replace the battery, carefully disassemble your key fob. It’s best to work on a clean, flat surface to avoid losing any small parts. Once open, remove the old battery and install the new CR2032 battery, making absolutely sure that it is fully inserted and making proper contact with both the positive (+) and negative (-) terminals. Double-check the polarity to ensure correct installation.
Take your time during this process. Rushing can lead to mistakes and frustration. After reinstalling the battery, carefully reassemble your key fob. Before closing it completely, test the buttons to ensure they are functioning correctly.
It’s also worth checking that the new battery doesn’t have any protective plastic film on either side, as this can sometimes be present and prevent proper contact. As a helpful tip, always replace the battery with the button side of the fob facing down. This minimizes the risk of accidentally dislodging any of the buttons inside the fob, which is a common issue during DIY battery replacements and can lead to the fob constantly sending signals to your vehicle.
Finally, consider replacing the battery in both of your key fobs at the same time. This practice ensures that both fobs have synchronized battery life, preventing the inconvenience of having to replace the battery in the second fob just a few months later. By following these steps, you can confidently replace your 2018 Honda CR-V key fob battery and keep your remote working perfectly.
