I have changed the battery and tried to reset it with the learn button method. I have even unplugged the opener then reset all remotes. The wireless keypad is the only one not working. It seems to open alot slower in the cold weather, that's why I thought it may be the battery. But now it will not work at all. Can any one give me ideas. I'm wondering if there is a way to know if the keypad is broken before just buying a new one Can anyone help ??
