The key fob for a 2010 Honda CR-V typically uses a 3-volt CR2032 coin cell battery.
This CR2032 is the standard choice for most Honda remotes from that era, offering reliable power in a compact form. If your remote looks different or you have a variant of the keyless system, check the battery label inside the compartment or refer to the owner's manual for the exact specification.
Battery type and compatibility
CR2032 coin cells are widely available at automotive stores, electronics retailers, and online. They’re also used in many other consumer devices, which makes replacements easy to source.
Notes on variations
While the vast majority of 2010 CR-V remotes use the CR2032, some regional or dealer-specific configurations may differ. If in doubt, confirm the battery type by opening the fob and checking the label on the existing battery.
How to replace the battery
If you’re replacing the battery yourself, you’ll want a clean workspace, a small flathead screwdriver, and a new CR2032. Follow these steps carefully.
- Locate the seam on the edge of the fob and insert the flathead screwdriver tip gently to pry the two halves apart.
- Separate the two halves and locate the old battery inside the housing. Note the orientation of the battery’s + side (often facing up).
- Carefully remove the old battery and dispose of it according to local regulations.
- Insert the new CR2032 with the correct polarity, ensuring the + side is oriented as the old battery was.
- Snap the fob halves back together and test the buttons to confirm the replacement was successful.
With the battery replaced, test the fob from several distances to ensure proper operation. If the range is poor or the buttons don’t respond, recheck the battery orientation and the case closure, or try a spare fob to determine if the issue is with the remote or the vehicle.
Additional tips and where to shop
CR2032 batteries are inexpensive and available at most auto parts stores, electronics shops, supermarkets, and online retailers. If you’re unsure which exact variant your fob uses, bring the old battery with you to confirm the size and polarity.
Summary
In short, a 2010 Honda CR-V key fob generally takes a CR2032 3-volt coin cell. Replacing it is a straightforward DIY task that involves opening the fob, swapping in the new battery with the correct orientation, and reassembling the case. Always dispose of old batteries properly and verify function after replacement.
