Title: Works for older Craftsman with red learn button
Product review: My Craftsman opener made in 2000 has a red learn button, but that does NOT made it a Security+ unit for which a 97xLM series will work. For purposes of a new remote, one must treat it like a Chamberlain or Genie unit vintage '93-'96 that has a GREEN learn button. Thus, buy either an 81LM series remote or a universal like the 375LM. If you buy the 375LM, program per instructions but with 4 button presses, not 2. Also, must press and immediately release (not hold) the button following each of the 4 presses (instructions are also vague on this point).
