I need help for a while now my garage door will open if I use the garage door pad and I don't have to hold it down but I use the remote and it won't work. I've tried changing the batteries and the only way it'll close(garage door pad) is if I hold it down till it closes completely. I don't know what the problem could be but its a hassle coming home turning the car off, getting in the house then opening the garage and turning the car back on to pull in the car and still holding down the button to close it. Please help, thanks!
