A security kit is provided for automatic closing of a garage door after a predetermined time of garage door being open. The security kit comprises a replacement wall switch for operating the garage door operating mechanism. The replacement wall switch comprises a timer module and a sensor disposed to detect that the garage door is open or closed. The sensor is coupled to a timer input. The sensor and the timer cooperatively operate such that when the sensor detects that the garage door is closed, the timer is reset and disabled, and further cooperatively operate such that when the sensor detects that the garage door is open, the timer initiates timing a predetermined time period. The timer operates a switch at end of the predetermined time period to cause the garage door mechanism to close the garage door. |
