Automotive Keyless Entry is a technology that allows drivers to unlock and start their vehicles without using a traditional key. Instead, it uses a remote control or a key fob that communicates wirelessly with the car. When the driver approaches the vehicle, the system detects the fob and unlocks the doors automatically. This system enhances convenience and security. Many keyless entry systems also include features like push-button start, which allows the driver to start the engine with the fob still in their pocket or bag. Overall, it simplifies the process of accessing and operating a vehicle.
