Six months ago, purchased a Sears (Lift Master) 1/2 hp with two 139.53681B (2/98) 'gray 3 button controllers' that worked great. Other garage opener was old style dip switch select Sears unit that required separate controller. Old unit finally broke primary sprocket, and replaced entire unit with new Sears 1/2 hp with two 139.53879 (8/99) blue button controllers (Security +).
Problem: Cannot program or use all four (2 gray button, 2 blue button) for both opener units. Can use only the gray button remotes for both openers, or use only the blue button units, but not combination of both.
The gray button unit has standard wall console, (no light or lock control button), new unit Security + has Premium Console with light and lock switch.
How can I program all four controllers to work on both openers??
