Basics Of Keyless Technology

Keyless technology in cars operates using a wireless remote and a receiver within the vehicle. The technology has evolved rapidly over the years, advancing from traditional keyless entry to more sophisticated systems. A traditional keyless entry system consists of a remote key fob, a car door sensor, and a receiver. When the remote key fob is within range, it sends a signal to the car’s receiver, unlocking the doors.

Modern keyless entry systems have incorporated advanced features such as push-button ignition, allowing the driver to start the car without inserting a key. Some vehicles are equipped with a proximity key, enabling keyless entry and ignition through a key fob or smartphone app. The evolution of keyless technology has improved convenience and security in accessing and driving vehicles.
