Yes — you can start a 2017 Honda Pilot even if the key fob battery is dead by using the emergency start method: hold the fob against the ENGINE START/STOP button while pressing the brake, then push the button to start. If that doesn't work, you can unlock with the mechanical key and replace the fob battery or use a spare fob.
The following guide explains the steps, alternatives, and preventive tips to handle a dead key fob, with sections on how the system works, step-by-step starting procedure, battery replacement, and safety considerations.
Understanding the smart key system in the Pilot
The 2017 Honda Pilot uses a proximity key fob (Smart Entry with Push Button Start). The car detects the fob's presence to unlock doors and start the engine. If the fob’s battery dies, you can still initiate a start by using the emergency method: hold the fob near the start button while applying the brake, and then press the start button to wake the engine.
Immediate steps to start with a dead fob
Use this sequence to attempt a normal start when the fob battery has died. Follow these steps calmly and ensure the vehicle is in a safe, parked position.
- Access the interior using the mechanical key blade hidden in the fob to unlock the driver’s door if the fob can’t unlock it remotely.
- Sit in the driver’s seat, press the brake pedal, and verify the transmission is in Park.
- Hold the dead key fob against the ENGINE START/STOP button (or very close to it) and firmly press the brake, then press the START/STOP button to start the engine.
- If the engine does not start, replace the fob battery or try a spare, if available, and attempt the start again.
- If you still cannot start after trying with a spare or a new battery, contact roadside assistance or consult the owner’s manual for model-specific instructions.
These steps cover the standard emergency start method for most 2017 Pilot models equipped with push-button start. If your exact vehicle shows a different procedure, refer to the manual or dealer guidance for your trim level.
Battery replacement for the key fob
Why replacing the battery matters
Most Honda key fobs use a coin-cell battery (commonly CR2032). Replacing the battery restores normal operation for locking/unlocking and the proximity sensing that enables push-button starts.
- Remove the mechanical key blade from the fob to access the back cover opening.
- Open the fob cover using a small flathead screwdriver or a coin, taking care not to damage the shell.
- Insert a fresh CR2032 battery with the correct polarity as indicated in the fob housing.
- Reassemble the fob and test the buttons to ensure the remote starts functioning, and try starting the vehicle with the fob again.
- If the vehicle still won’t start after replacing the battery, you may need to reprogram or replace the fob at a dealer or locksmith, especially if the vehicle doesn’t recognize the key.
Battery replacement is a straightforward maintenance step that typically restores full functionality without professional service, though consult the dealer if the fob continues to misbehave.
Preventive tips to avoid future dead fobs
- Regularly check the fob battery life and replace it at the first signs of weakness (e.g., slower response, delayed unlocking).
- Keep a spare fob battery or a spare fob in a safe, accessible place in your vehicle or home.
- Store the fob away from extreme heat or moisture to extend battery life.
- Know the location of the mechanical key blade in your fob for quick door access if the fob is unresponsive.
By staying proactive with battery maintenance and having a plan for access, you reduce the chances of being stranded due to a dead fob.
Notes on safety and legality
Always ensure you are authorized to operate the vehicle. If you are not the owner, obtain permission and follow warranty or roadside assistance guidelines. Do not attempt unauthorized access or manipulation of the vehicle’s security systems beyond the manufacturer’s recommended emergency procedures.
Summary
For a 2017 Honda Pilot with a dead key fob, the primary path to starting is the emergency start method: hold the dead fob against the ENGINE START/STOP button while pressing the brake, then press the button to start. If that fails, use the mechanical key to access the vehicle and replace the fob battery or use a spare fob. Regularly replace the fob battery (commonly CR2032), keep a spare on hand, and consult the owner’s manual or a dealer if problems persist. Proper maintenance and preparedness can prevent delays and ensure a smooth return to the road.
