A remote pairing device is provided. The remote paring device includes a processor to execute the following steps. A plurality of controlled elements is divided into a restart group and a force-shutdown group. Each of the controlled elements is connected to an electronic device. A restart command is sent to the controlled elements in the restart group. A force-shutdown command is sent to the controlled elements in the force-shutdown group. The pairing candidate lists each corresponding to the controlled elements are updated according to the connection status corresponding to the electronic devices received during a specific time period after sending the restart command or the force-shutdown command. Determining that the controlled elements corresponding to the pairing candidates list having only one electronic device therein are successfully paired.
