Remote Key

A remote keys, also known as remote keyless entry, is a device used to remotely control a vehicle’s locking and unlocking functions, as well as other features such as the alarm system, trunk release, and in some cases vehicle heating or engine start.

Remote key fobs typically consist of a small plastic case with one or more buttons, and use radio-frequency (RF) technology to communicate with the vehicle’s onboard control unit. When the driver presses a button on the remote fob, it sends a signal to the vehicle, which then performs the requested function.

In addition to locking and unlocking the doors, remote key fobs may also be used to remotely start the vehicle’s engine. Some key fobs may also include features such as keyless ignition, which allows the driver to start the engine without inserting a physical key into the ignition switch.
