A method unlocks a portable electronic device using a stylus. A user can remove the stylus received in a receiving space of the portable electronic device to unlock the portable electronic device. In an unlocking procedure, a detection circuit detects whether the stylus has been removed from the portable electronic device and outputs a corresponding logic value of the portable electronic device. If the logic value of the detection circuit has changed from “0” to “1”, the locked portable electronic device is unlocked. |
