A method for unlocking an electronic equipment, comprising: detecting periodically, by the electronic equipment, whether there is an unlocking key in its surrounding environment, and when there is an unlocking key in the surrounding environment, transmitting an unlocking request to the unlocking key; receiving, by the unlocking key, the unlocking request, determining in accordance with the unlocking request whether the electronic equipment matches the unlocking key, and when it is determined that the electronic equipment matches the unlocking key, transmitting an unlocking signal to the electronic equipment so as to unlock the electronic equipment; wherein the step of detecting periodically, by the electronic equipment, whether there is an unlocking key in its surrounding environment comprises: outputting, by the electronic equipment, a wireless signal, wherein the wireless signal carries graphic identifier information of an unlocking key that matches the electronic equipment; receiving, by the unlocking key, the wireless signal and acquiring the graphic identifier information carried in the wireless signal; determining, by the unlocking key, whether the graphic identifier information carried in the wireless signal is consistent with preset information, and when it is determined that the graphic identifier information carried in the wireless signal is consistent with the preset information, outputting an acknowledgement signal to the electronic equipment; determining, by the electronic equipment, whether the acknowledgement signal is received within a preset period of time, determining that there is an unlocking key in the surrounding environment when it is determined that the acknowledgement signal is received within the preset period of time, and determining that there isn't an unlocking key in the surrounding environment when it is determined that the acknowledgement signal is not received within the preset period of time. detecting periodically, by the electronic equipment, whether there is an unlocking key in its surrounding environment, and when there is an unlocking key in the surrounding environment, transmitting an unlocking request to the unlocking key;
