Remote control key and vehicle

A remote control key and a vehicle, the remote control key comprises a metal outer frame and a circuit board, the metal outer frame defines an accommodating space, the metal outer frame is provided with a first end portion and a second end portion, and the first end portion is connected with a ground wire; and the circuit board is accommodated in the accommodating space, the circuit board is provided with a radio frequency circuit used for transmitting radio frequency signals, and a feed point of the radio frequency circuit is electrically connected with the second end part, so that the metal outer frame radiates the radio frequency signals. According to the remote control key, the metal outer frame serves as the antenna of the remote control key, so that the antenna is exposed out of the surface of the remote control key, the influence of metal on the remote control key on antenna radiation is reduced, and the signal receiving and transmitting performance of the remote control key is improved.
