What tools and battery type do you need for a Honda CR-V key fob?
You’ll need a CR2032 coin cell battery, which is a 3V flat lithium battery available at hardware stores, auto shops, or online. For tools, use the mechanical key from your fob or a small flathead screwdriver to pry open the case. Fasta Power advises using gloves or a clean cloth to avoid leaving oils on the new battery, which can shorten its lifespan.

How To Change Battery In Honda CRV Key Fob?
To change the battery in a Honda CRV key fob, slide the button to release and remove the mechanical key. Use a small flathead screwdriver or the key to carefully pry open the fob.

To change the battery in a Honda CRV key fob, start by sliding the small button on the back of the fob to release and remove the mechanical key hidden inside. This key is essential for safely opening the fob without causing damage. Next, use a small flathead screwdriver or the mechanical key itself to gently pry open the fob’s two halves. Be careful not to use excessive force to avoid breaking the plastic casing. Once opened, you will see the old battery—usually a CR2032 coin cell battery—carefully remove it, paying close attention to its orientation (which side is facing up), as the new battery must be inserted the same way to ensure proper function.
After inserting the new battery, firmly press the two halves of the fob back together until they snap securely. Then, reinsert the mechanical key back into its slot. It’s a good idea to test the key fob immediately by pressing the buttons to confirm the battery replacement was successful.

This simple maintenance step can save time and hassle, ensuring your Honda CRV’s keyless entry system functions smoothly.
