My garage door openers won't work!!?

I have two carage door openers..One a genie intellicode and the other is a new chamberlain liftmaster. A few weeks ago they both quit working! They both work from the wall mounted controls and if i stand right next to them with the transmitters for the cars they will both work. When the doors are down and we try to open them with our car transmitters we get nothing. I also have touch pads for both mounted outside and these have quit working also!!! I have reprogrammed both openers, changed all the batteries and NOTHING WORKS!!! Someone PLEASE HELP!!!!
