The standard CR-V key fob battery is a CR2032 3V lithium coin cell. This size covers most recent models, but some older or regional remotes may use CR2025 or another coin cell. Always verify by inspecting the fob or consulting the owner’s manual.
Common sizes found in Honda CR-V remotes
The following list highlights the sizes you’re most likely to encounter in CR-V key fobs. Use it as a quick reference to avoid buying the wrong battery.
- CR2032: The vast majority of modern CR-V remotes use this 3V coin cell.
- CR2025: Some older or regional remotes may use this thinner alternative.
- Other sizes: Extremely rare cases exist; if in doubt, confirm by opening the fob or checking the manual.
When in doubt, start with CR2032, since it is the default for most Honda remotes. If the fob doesn’t operate after replacement, re-check the size and orientation or consult dealer guidance.
How to identify and replace the battery
Follow these steps to safely identify the correct size and replace the battery in your CR-V key fob.
- Inspect the existing battery by opening the fob’s back cover to confirm the size printed on the battery (if visible) or compare with common sizes (CR2032 vs CR2025).
- Purchase a fresh CR2032 battery (3V) as the default choice for most CR-V remotes.
- Using a small flat tool or coin, carefully pry open the back cover without forcing or damaging the casing.
- Remove the old battery, noting the orientation (which side faces up). Place the new battery in the same orientation.
- Reassemble the fob and test all functions (lock, unlock, trunk release, or remote start where applicable).
A few tips: handle the battery with clean hands, avoid touching the battery’s contact surfaces with bare fingers, and ensure the fob is fully closed to prevent moisture ingress.
Summary
For most Honda CR-V key fobs, the replacement battery is a CR2032 3V coin cell. While CR2032 is the standard, some older or regional remotes may use CR2025. Always verify by inspecting the fob or consulting the owner’s manual, and follow proper replacement steps to restore functionality.
