The garage door remotes and keypad works only when i,m very close to opener, will not work at more then 6 ft away from opener. sears hbw0777

How old are the batteries in the remotes and keypad? Replace the batteries. If that helps, then you have solved the problem.

If it doesn't help, then check the antenna wire of the opener. (Make sure it is extended down from the unit.) Note this doesn't apply to all garage door openers. (We have several models - some with the external antenna and some without.)

Does your garage have metal walls and metal doors? This can shorten the range between the receiver and the remotes or keypad. An antenna extension may be available.

I don't see the HBW077 as a model number at Sears Parts Direct or Manage My Life. Please check the model and let me know if I can provide any additional assistance. (Sears Parts Direct has parts for my garage door openers. Manage My Life has manuals for Craftsman and Sears appliances.)

I hope this helps.
