The 2017 Honda CR-V key fob uses a CR2032 3-volt lithium battery.
That coin-cell battery is standard for most Honda remotes from around that year. If your fob seems to require a different size, inspect the current battery inside the fob or consult the owner's manual or Honda support, as variations can occur with different regional models or trims.
Confirming and replacing the battery
The steps below guide you through identifying the correct battery and replacing it in a typical 2017 CR-V key fob.
- Open the fob by gently prying apart the two halves along the seam using a small flat tool or coin. Avoid using excessive force to prevent damage.
- Carefully remove the old battery and note its size and orientation. In most CR-V fobs this is a CR2032, with the positive (+) side facing up.
- Insert a new CR2032 battery with the + side facing up, ensuring it sits flat and fully seated in the battery compartment.
- Snap the halves back together until they click, then test the fob by pressing a button to confirm it’s working.
Be sure to handle batteries with care, avoid touching the battery contacts with your fingers, and dispose of the old battery according to local regulations.
Variant notes
While CR2032 is standard for most 2017 CR-V key fobs, Honda has produced different remote designs for some markets or trims that may use CR2025 or other coin cells. If the CR2032 does not fit or the fob seems nonfunctional after replacement, check the owner’s manual for the exact specification or contact a Honda dealer for confirmation.
Summary
For a 2017 Honda CR-V key fob, plan to use a CR2032 3V lithium battery. If in doubt, inspect the current battery, refer to the manual, or contact a dealer. Replacing is straightforward: pry open the fob, replace the battery with the correct size oriented correctly, and snap the case closed, then test the remote.
