PROBLEM TO BE SOLVED: To provide a smart entry system that allows a reacting distance of a smart key to be adjusted, when a polling method is used.SOLUTION: A smart entry system that unlocks an opening/closing body includes: a transmission part 110 transmitting a calling signal to a portable key 100B through a wireless communication; a receiving part 120 receiving a response signal from the portable key 100B that responds to the calling signal; and a control part 130 outputting a command to the transmission part 110 to transmit the calling signal, verifying the response signal when the receiving part 120 receives the response signal, and outputs a command to unlock the opening/closing body based on a result of the verification. The calling signal is transmitted by a polling method, and an output intensity setting part 132 is disposed on the control part 130 for changing and setting an output intensity of the calling signal.SELECTED DRAWING: Figure 1 |
