Have had previous incidents that my Liftmaster key pad attatched to my Toyota car key pad in my pocket has unknowingly opened my garage door, sometimes overnight. Now I know from upstais in my office just by seeing a little green light that the garage door is closed.
But if there is a red light I just push the button on the monitor to close the door.
Great Product!

The item was what we expected and it fit our system like a glove. We recommend this company. The price was very fair and their responce was prompt.
