The standard Honda Pilot key fob typically uses a CR2032 3V coin-cell battery. This is the most common size across recent Pilot models.
Battery size can vary by year and fob variant, so if your remote looks different or your owner’s manual specifies another option, verify the exact size before purchasing a replacement. Inspect the back of your fob or the manual for the precise code if in doubt.
Common battery sizes for Honda Pilot key fobs
The following sizes cover the typical options you might encounter in Pilot remotes. Use the size that matches your specific fob to ensure proper fit and operation.
- CR2032 — 3V lithium coin cell; the most widely used size for Honda Pilot key fobs in recent years.
- CR2025 — 3V lithium coin cell; used in some older or regional remotes and may fit certain fob designs depending on spacing.
If your fob uses a different size, consult the owner’s manual or inspect the current battery for the size imprint to confirm compatibility.
Replacing the key fob battery
Follow these steps to replace the battery safely and get your remote back in working order.
- Flip the fob over and locate the seam along the edge. Use a small flathead screwdriver or a coin to gently pry the back cover open.
- Remove the back cover and take out the old battery. Note the orientation of the positive (+) side so you can place the new battery correctly.
- Insert a new CR2032 (or the indicated size) with the correct polarity, ensuring it sits flat and secure.
- Snap the back cover back into place until it clicks firmly.
- Test the fob by pressing a button to confirm it unlocks/locks from a short range.
If the fob does not respond after replacement, re-check the battery orientation and seating, or try a fresh battery. If it still fails, the issue may be with the fob’s internal circuitry or the car’s receiver, and you may need professional assistance.
Model-year caveats
Most Honda Pilot remotes use CR2032, but a small subset of older vehicles or regional variants might use CR2025. If you’re unsure, refer to your owner’s manual or check the battery currently in the fob—the size is usually printed on the battery itself or indicated in the manual.
Summary: For most Honda Pilot key fobs, expect a CR2032 3V battery. Some variants may use CR2025. Replace with the correct size, follow proper orientation, and test the fob. If problems persist, seek professional assistance to rule out transmitter or receiver issues.
