Abstract: This disclosure describes an electrical power cord, which, by using a programmable on/off power timer, will enable or disable power from flowing through said power cord. It also describes a method for locking and unlocking a plug to and from the female receptacle of said power cord. The purpose of such a power cord is to control the time of use of any electrical device that may be plugged in to said power cord, by programming a programmable on/off power timer to allow a flow of current to that device at desired periods during a week and by locking the plug of said device to the female receptacle of said power cord. The programmable on/off power timer is locked within the same enclosure as the said plug. When the appropriate key is used, the timer can be accessed for programming, or the plug may be removed.
