What is a Key Fob?
To fully understand how to start your Mazda in the case that your key fob dies, it is helpful to understand exactly how key fobs work. A key fob is the pre-programmed hardware device that locks and unlocks your car doors. It is generally attached to the physical key that you can use to manually unlock the doors of your car. Key fobs are usually equipped with a simple set of buttons that allow you to lock and unlock your car, sound your car’s alarm, or even pop open the trunk of your car.
They might look simple, but the technology that is included inside these tiny devices is actually quite complex. Your car’s key fob is a critical component of the security of your car. Traditional key fobs that allow you to unlock and lock your car doors from a distance are equipped with short-range radio transmitters that send coded signals via radio waves to your car when you press a button on the fob from within a certain distance of your vehicle.
Even if your car is equipped with remote and/or push-button start capabilities, it is likely still connected to a key fob. Key fobs for these high-tech cars transmit low-frequency signals that are transmitted to your car’s built-in computer system and allow your car’s engine to respond when you get into your car and press its ‘Start’ button. Some advanced key fobs also serve other purposes and can lower your car windows, open your car’s sunroof, fold in your car’s side mirrors, and more.

Start by turning your car key over. Locate the small latch on the back of the key fob. Release and pull down on the latch. A hidden traditional physical key should emerge from the inside of the fob. To unlock the doors of your Mazda, insert this traditional key into the keyhole on the driver side door and turn it to manually unlock the door.
If your vehicle is equipped with push-button start, you might be at a loss on how to start your car’s engine when you’re stuck with a dead key fob. Start your Mazda with a dead key fob by pressing your foot down on the car’s brake and simultaneously pressing the Mazda symbol that is located near the top of your key fob against the push-button start area of your vehicle. A small chip inside the key fob will connect to the vehicle and command the car’s engine to start.
