For the life of me, I can't find programming instructions for the 5-number
All the programming instructions I can find are for a "similar" but different keypad, e.g.,
Called Clicker/Chamberlain/LiftMaster main customer support phone number 800-528-5880 but they have no old instructions & the new ones don't work.
All they have are CLK1D, CLK1R, KLIK2U, etc. such as this CLK1D PDF.
Any idea how to find the correct instructions that actually list the model?
