A dead key fob doesn’t have to leave you stranded. You can start the 2020 Honda Pilot by using the vehicle’s emergency start method: unlock with the mechanical key, then start the engine by holding the fob near the Start/Stop button while pressing the brake. Replacing the fob battery will restore normal operation.
Understanding how the system works
The 2020 Honda Pilot uses Honda’s Smart Entry with Push Button Start. When the fob battery is dead, the system may not detect the fob, which can prevent starting the engine. Honda provides a backup procedure to get moving even with a dead fob battery, so you can reach a safe location to replace the battery.
Emergency start steps (dead fob)
Before attempting the steps below, ensure you can access the driver’s door and that you’re safely seated with the transmission in Park (P) and your foot on the brake.
- Remove the mechanical key blade from the fob. Use the small release to slide out the metal key, then use it to unlock the driver’s door if the fob won’t unlock the door remotely.
- Enter the vehicle, fasten your seat belt, and press the brake pedal. Verify the transmission is in Park (P).
- With the brake pressed, place the fob close to the Start/Stop button and press the button to start the engine. If the fob is detected, the engine will start. If needed, hold the fob against the Start/Stop button while applying the brake and pressing the button again until the engine cranks.
- If the engine doesn’t start, reposition the fob and retry. Keep the fob inside the vehicle or near the Start/Stop button as you attempt again.
- Once the engine is running, drive to a safe location and arrange to replace the fob battery as soon as possible to restore normal operation.
Note: The emergency start method is intended for temporary use. Replacing the fob battery is the quickest way to restore full functionality.
Replacing the key fob battery (CR2032)
The Honda key fob commonly uses a CR2032 lithium battery. Replacing it is a quick fix that restores remote functions and push-button starts.
Steps to replace the battery
- Open the fob housing by gently prying apart the two halves, then locate and remove the old battery.
- Insert a new CR2032 battery with the correct polarity (positive side facing up in most fobs).
- Reassemble the fob and test the buttons and Start/Stop function to confirm the battery is working.
If you continue to have trouble starting after replacing the battery, contact a Honda dealer or roadside assistance for further diagnosis.
Tips to prevent future issues
Keep a spare fob battery and consider replacing the fob battery every couple of years or whenever you notice reduced range or sluggish responses. Regular checks can help avoid being locked out or unable to start.
Summary
A dead key fob for a 2020 Honda Pilot can be managed with an emergency start: use the mechanical key to access the door, then hold the fob near the Start/Stop button while pressing the brake to start the engine. Afterward, replace the fob battery to restore normal operation and avoid recurring issues. If in doubt, consult the owner’s manual or contact a dealer for assistance.
