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!
On a Saturday, I called the number on the website to see how to return a torsion spring since I ordered the wrong one. The employee walked me through reversing the installation so I would not have to return the spring. I highly recommend this compnay for all your garage door needs.
