The key fob for a 2019 Honda Pilot typically uses a CR2032 3-volt lithium coin battery.
In most Pilot fobs, this standard coin cell powers remote entry and panic functions. If your fob looks different or you have an aftermarket or regional variant, verify the exact size by inspecting the battery compartment or consulting the owner's manual or a Honda dealer.
Identifying the right battery for your fob
Before replacing, confirm the correct battery size to avoid mismatches. The CR2032 is the general standard, but rare regional editions may use a different coin cell.
- CR2032 — 3V lithium coin cell; the most common size for 2019 Pilot key fobs
- CR2025 — 3V lithium coin cell; less common for Pilot fobs and may not fit if the housing differs
- CR1632 — 3V lithium coin cell; very rare for this model
Note: If unsure, check the size printed on the current battery or refer to your owner's manual or a Honda dealer for confirmation.
How to replace the battery
Here are the typical steps for swapping in a new battery without damaging the fob:
- Use a small flathead screwdriver or a gentle pry tool to separate the two halves of the fob, starting at the seam
- Take out the old battery and observe the orientation (positive side usually faces up)
- Insert the new CR2032 (or the correct size) with the correct polarity
- Snap the halves back together and test the remote functions
Pro tip: If the fob’s buttons feel loose or a test fails, re-check the battery orientation and ensure the contacts are clean and undamaged.
Tips for testing and care
Test the fob by locking/unlocking doors and starting the engine if your Pilot is keyless-start. Extreme temperatures and moisture can affect fob performance, so handle and store properly.
Where to buy the right battery and warranty notes
CR2032 batteries are widely available at auto parts stores, battery retailers, and Honda parts departments. If you’re unsure or the fob remains unresponsive after replacement, contact a dealer for a quick diagnostic or battery replacement service.
- Standard battery size for most 2019 Pilot key fobs: CR2032

Bottom line: For the 2019 Honda Pilot key fob, expect a CR2032 battery, with exact size verified by the fob itself or the manual.
