Starting a Honda Accord when your smart key fob battery is dead or the fob isn't responding requires a few specific steps, leveraging the physical key hidden within your fob for entry and a special technique for ignition. The physical key is primarily for gaining access to your vehicle when electronic functions fail.
Gaining Entry: Using the Physical Key
When your Honda Accord's smart key fob battery dies, you won't be able to unlock the doors using the buttons on the fob. This is where the integrated physical key becomes essential.
- Retrieve the Physical Key: Most Honda smart key fobs contain a hidden physical key. Look for a small release button or tab on the side or back of the fob that allows you to pull out the metal key blade.
- Unlock the Driver's Door: Locate the keyhole, typically on the driver's side door handle.
- Insert the physical key into the keyhole.
- To unlock the door: Turn the key clockwise. As per the reference, "And voila the door opens."
- To lock the car: Turn the key counterclockwise. The reference states, "If you want to lock the car it's just the opposite. Put it back in turn it counterclockwise. And the car locks."
| Action | Key Turn Direction | Result |
|---|---|---|
| Unlock Door | Clockwise | Door opens |
| Lock Door | Counterclockwise | Car locks |
Starting the Engine with a Dead Smart Key Fob
Once you've gained entry to your Honda Accord, starting the car with a dead or unresponsive smart key fob requires a specific procedure, as there typically isn't a traditional ignition cylinder for the physical key.
- Enter the Vehicle: Get into the driver's seat.
- Locate the Push-Button Start: Your Honda Accord will have a "START/STOP ENGINE" button on the dashboard.
- Place the Smart Key Fob: Even with a dead battery, the smart key fob contains a transponder chip that the car's immobilizer system can often detect at close range.
- Directly touch the smart key fob to the push-button start button.
- Alternatively, some older models might have a designated slot or area near the steering column to place the fob.
- Press the Brake Pedal: Ensure your foot is firmly on the brake pedal (for automatic transmission) or clutch (for manual transmission).
- Press the Start Button: While the fob is touching the start button (or in its designated slot), press the "START/STOP ENGINE" button as you normally would. The vehicle should now start, as the car's system can read the fob's transponder chip.
Important Considerations
- Fob Battery Replacement: This method is a temporary solution. It's crucial to replace the battery in your smart key fob as soon as possible to restore its full functionality and convenience. Most fobs use a CR2032 lithium coin battery, which is readily available.
- Security System: If your car's alarm goes off when you unlock the door with the physical key, simply starting the car with the fob usually disarms it.
- Regular Maintenance: Check your key fob battery regularly, especially if you notice a decrease in its range or responsiveness.
Following these steps will allow you to start your Honda Accord even when facing a dead smart key fob battery, ensuring you can get back on the road.
