How to Start the Car When the Key Fob Battery Dies?

[SanTyler]

When the key fob battery for push-button start dies, you can use the spare mechanical key to start the car. Here are the relevant details: 1. Spare Mechanical Key: Regardless of brand or price, all car keys come with a built-in spare mechanical key—either foldable or hidden. 2. Mechanical Key Slot: Some car models hide the mechanical key slot inside the door handle for aesthetic reasons, requiring you to pry open a protective cover to access it. 3. Key Recognition Zone: Cars with push-button start functionality are equipped with an engine immobilizer system that matches a security code with the key. In this case, simply locate the designated key recognition zone in the car and place the key there to start the engine with the push-button.
