I have 2 remotes for 2 garage doors. both are original sears 3 button remotes. each remote operates the door on the left fine, but will not operate the door on the right unless within a few feet and push and wiggle the button. How can I program the remotes to use the 3rd button for the door on the right. The openers are 2 wire units and both work fine with the wall unit. Model # 139.53300 is a 1/3 HP and Model # 139.53606 is a 1/2 HP.
