The invention provides an emergency unlocking method, a device and a system. When a vehicle is in an unlocking state but a monitoring center cannot unlock the vehicle remotely, a user can call the monitoring center to obtain an unlocking password and input the unlocking password into an engine controller, the engine controller verifies whether the unlocking password is in an unlocking password unlocking group which is pre-stored in the engine controller after the engine controller receives the unlocking password, and the unlocking password is correct if the unlocking password exists in the engine controller, therefore the vehicle can be allowed to drive freely during the preset time and can be conveniently driven out a dangerous area under the control of a user. Therefore, an aim of carrying out unlocking emergency on the vehicle under the condition that the remote unlocking is out of work can be achieved so as to prevent casualties and accidents.
