Experiencing a dead key fob battery can be more than just an inconvenience, especially when you’re in a hurry or facing inclement weather. For Subaru owners, understanding how to navigate this situation is crucial. Fortunately, Subaru vehicles are equipped with backup systems to ensure you’re not stranded. This guide will walk you through the steps on how to start your Subaru even when your key fob battery is dead.
First and foremost, familiarize yourself with the emergency key, also known as the mechanical key, that’s housed within your Subaru key fob. This key is designed precisely for situations like a dead fob battery or a dead car battery. Locate the small release button or latch on your key fob. Press or slide this to detach the emergency key from the fob.
This emergency key is your first line of defense. It functions just like a traditional car key. You can insert it into the driver’s side door lock to manually unlock your Subaru. Once inside, even with a dead key fob, you can still start your Subaru.
Here’s how to start your Subaru with a dead key fob using the push-button start system:
- Enter your Subaru using the emergency key. Unlock the driver’s side door manually with the detached emergency key. The alarm might sound, but don’t worry, it should stop once the car is started.
- Get into the driver’s seat and close the door.
- Press the brake pedal firmly. This is a standard step for starting push-button ignition vehicles.
- Take your key fob and hold it close to the START/STOP ignition button. The key fob contains a transponder chip that, even without battery power, can be detected by the car when in close proximity to the start button. The optimal spot is usually directly touching the button or within an inch or two.
- While holding the fob near the button, press the START/STOP ignition button as you normally would to start your Subaru. The vehicle should recognize the fob’s transponder and start the engine.
This method leverages the Passive Keyless Entry and Start system in your Subaru. Even when the fob’s battery is depleted and the remote functions are inactive, the transponder chip itself remains functional and can communicate with the vehicle when in close range of the ignition button.
Important Considerations:
- Key Fob Battery Life: Key fob batteries typically last for a few years. Pay attention to warning signs like decreased remote range or the need to press buttons multiple times. Replace the battery proactively to avoid getting caught off guard.
- Spare Key Fob: Always keep a spare key fob at home or with a trusted person. In a pinch, having a functional spare can save significant hassle.
- Subaru Starlink (If Applicable): If you are subscribed to Subaru Starlink, depending on your subscription level, you might be able to use the Starlink app on your smartphone to remotely unlock your doors. However, Starlink is not a method to start your car with a dead key fob, but it can help you access your vehicle if you’ve locked yourself out.
- PIN Code (Older Models – Verify if applicable): Some older Subaru models might have a PIN code entry system on the door. Consult your owner’s manual to see if your vehicle has this feature and how to use it. However, this is less common on newer models with push-button start.
Knowing how to start your Subaru with a dead key fob ensures you’re prepared for unexpected situations. By understanding the emergency key and the proximity start method, you can confidently handle a dead key fob battery and keep your journey uninterrupted. Remember to replace your key fob battery regularly and keep a spare key in a safe place for added security and convenience.
