There’s usually a hidden key inside the fob itself, or a designated spot near the steering column or inside the center console where you can place the fob to start the car.

This passive system may allow you to unlock the car by touching a specific spot on the door handle. Once inside, there’s usually a designated area, often in the center console or near the start button, where you can place the dead key fob to start the car.
