Replacing the battery in your 2017 Honda CRV key fob is a simple task that doesn’t require any reprogramming. This guide will walk you through the process, ensuring a smooth and successful battery replacement for your key fob.
Ensuring Your New Battery is Good
Before you start, it’s crucial to verify that your new CR2032 battery is functioning correctly. A fresh CR2032 battery should register a voltage between 3.3 and 3.4 volts DC when measured with a voltmeter. The low battery warning in your Honda CRV typically activates when the key fob battery voltage drops to around 3.1 volts. This sharp voltage drop towards the end of the battery’s life is why the system is designed to alert you at approximately 3.1 volts.
When installing the new battery, double-check the polarity (+ and -) to ensure it’s correctly placed in the key fob. Incorrect polarity will prevent the key fob from working.
Step-by-Step Battery Replacement
Take your time and work carefully to avoid any issues. Rushing the process can lead to frustration or damage to your key fob.
-
Disassemble the Fob: Carefully open your Honda CRV key fob. Refer to your owner’s manual for specific instructions on how to open your key fob model.
-
Remove the Old Battery: Once open, gently remove the old, depleted battery from its housing.
-
Insert the New Battery: Place the new CR2032 battery into the compartment, ensuring the correct polarity is observed. Make sure the battery is fully inserted and makes proper contact with both the positive (+) and negative (-) terminals.
-
Reassemble the Fob: Carefully close and reassemble the key fob, ensuring all parts fit snugly back together.
Before reassembling, double check that there isn’t any plastic protective film on the new battery. Some batteries come with this film to prevent discharge, and it must be removed for the battery to work.
Important Tips for Key Fob Battery Replacement
-
Work on a Flat Surface: Always perform the battery replacement with the button side of the key fob facing down on a clean, flat surface. This prevents the buttons from being accidentally dislodged.
-
Handle with Care: The most common problem after a key fob battery replacement is buttons becoming loose due to careless handling. Be gentle when handling the open key fob components.
-
Replace Both Fob Batteries: For optimal performance and to maintain synchronized battery life, it’s recommended to replace the batteries in both of your Honda CRV key fobs at the same time. This prevents one key fob from failing shortly after the other.
By following these steps and tips, you can easily replace the battery in your 2017 Honda CRV key fob and ensure it continues to function reliably.
