The most common battery is CR2032, but some older or smaller fobs may use CR2025 or CR1632. Verify the exact size by inspecting your fob or checking the owner's manual.
Identifying the correct battery size for your CR‑V key fob
The size of the key‑fob battery depends on the model year and the specific fob variant. The majority of newer Honda CR‑V remotes use a CR2032 coin cell, while older or smaller remotes can use CR2025 or CR1632. The following sizes cover the vast majority of CR‑V key fobs.
- CR2032 – The most common choice for newer CR‑V remotes and smart keys.
- CR2025 – Used in some older or alternative fob designs.
- CR1632 – Found in a few early or compact fob variants.
If you’re unsure which one you have, compare the battery to an identical size coin cell, check the back of the fob for a size mark, or consult the owner’s manual or a Honda dealer for confirmation.
Quick verification tips
To confirm without disassembly, you can take the old battery to a parts store and have staff help match the size, or look up your specific CR‑V year and trim to see the standard fob used by that configuration.
Replacing the battery
Replacing a CR‑V key fob battery is a simple, at‑home task. Gather a replacement battery of the same size and a small tool such as a coin or flathead screwdriver to open the cover.
- Open the back cover: Flip the fob over and locate the seam. Use a coin or small flat tool to gently pry the back off.
- Remove the old battery: Note the orientation of the positive (+) side before lifting it out.
- Insert the new battery: Place the new coin cell in the same orientation as the old one, usually with the + side facing up.
- Close and test: Snap the back cover back on and press the buttons to confirm the remote works from a short distance.
After replacing, discard the old battery properly at a recycling facility or retailer that accepts batteries. If the remote still doesn’t work after replacement, double‑check that you installed the correct size and orientation, and consider having the fob inspected for other issues.
Tips for choosing and caring for your fob battery
Use high‑quality, reputable brands for reliability. Avoid rechargeable button cells, as most fobs require a non‑rechargeable coin cell. Store spares in a cool, dry place and replace the battery before it shows a noticeable drop in range or responsiveness.
Summary
For most Honda CR‑V models, the standard battery is CR2032, with CR2025 or CR1632 appearing in some older or alternate fob designs. Always verify by inspecting the fob or consulting the owner’s manual. Replacing the battery is an easy, routine maintenance task that restores key fob performance with a fresh coin cell.
