They permit your car to start at any time you use them. This chip transmits a unique code to the engine immobilizer in the car, letting it be aware that it's a legitimate key. The chip sends this ID code via radio to the car's computer. If the ID code matches the one stored in the car's memory, the car's security system will turn off the immobilizer, allowing the engine begin.
