Keyless car starters, also known as FOBS (Four-Letter Operated Buttons), are a type of technology that allow drivers to start their cars without the need for a physical key. They use a wireless signal to activate the car's ignition system, allowing drivers to start their cars with the press of a button. FOBS are becoming increasingly popular due to their convenience and security features, as they can be programmed to only work with the owner's car.
