      Help! Does anyone know how to turn off the lock feature on my main key pad for my garage door opern model Sears Craftman 1/2HP 139.53635SRT? I just bought my home and the owner did not leave me the manual. The lock features seems to go on and off at it’s own will…I must admit though…it’s probably user error.

      Chamberlain make the Chamberlain, Liftmaster and Sears openers. They all use common parts and work similarly.

      This manual is for a Chamberlain that uses the some control board as yours so the proceedures should all be the same.
