It uses a CR2032 3-volt coin cell battery.
The standard 2010 Honda Pilot key fob is designed around a CR2032 coin cell. If you’re unsure about your exact remote variant, you can verify by inspecting the back cover once you remove the mechanical key or by checking the owner’s manual for battery specifications.
Battery Type and Compatibility
For most 2010 Pilot remotes, the CR2032 is the appropriate replacement. Some occupants may have different fob configurations, such as aftermarket remotes or dealer-installed variants, which could use different batteries. When in doubt, confirm by opening the fob to view the existing battery or referencing your vehicle’s documentation.
Variations by Fob Style
While CR2032 is the common choice, certain regional or dealership variants may differ. If your fob looks markedly newer or older than typical models, or if you’ve recently replaced the ignition system or remote, verify the exact battery model before purchasing a replacement.
Replacing the Battery
To ensure you install the correct replacement and maintain remote functionality, follow these steps carefully.
- Obtain a fresh CR2032 3V coin cell battery from a reputable retailer.
- Remove the mechanical key blade from the fob to access the back cover.
- Gently pry open the back cover at the designated notch using a small coin or flat-head tool.
- Carefully lift out the old battery and dispose of it properly.
- Insert the new CR2032 battery with the positive (+) side facing up toward you when the fob is lying face up.
- Snap the back cover back into place and reinsert the mechanical key blade if you removed it.
- Test the remote by pressing the lock/unlock or trunk button to confirm it works.
If the fob still doesn’t respond after replacing the battery, the issue may be with the transmitter or the vehicle receiver, and service at a Honda dealership or a qualified locksmith may be required.
Summary
For a 2010 Honda Pilot, the key fob typically uses a CR2032 3-volt coin cell battery. Replace it by opening the fob, swapping in a new CR2032 with the correct orientation, and testing the remote. If performance issues persist, seek professional assistance to rule out transmitter or receiver problems.
