The invention discloses an intelligent automobile key. The intelligent automobile key comprises an automobile key body, a circuit board, an audio plug, a security
encryption chip, a communication
chip and a
function indicator lamp set. The circuit board is arranged in the automobile key body. The audio plug is arranged on the side face of the automobile key body and is connected with the security
encryption chip. The security
encryption chip is connected with the communication chip and is arranged on the circuit board. The communication chip is connected with the automobile key body and the
function indicator lamp set. By means of the mode, the intelligent automobile key solves the problems that in the prior art, when functions are achieved through a 3G module, cost is high, operation is complex and
delay is high; the intelligent automobile key can be connected with a
smart phone to be expanded, and more abundant vehicle information can be provided through the powerful calculation function of the
mobile phone; meanwhile, by means of the calculation function of the
mobile phone, an automobile can be conveniently and rapidly managed, and the intelligent automobile key is easy and convenient to operate, low in cost and high in real-time performance.
