  • Replace Dead Batteries: Sometimes the problem lies in your old, damaged batteries of the door opener. You can try new ones to remedy the situation.
  • Reprogram the Remote: There is a chance of the remote being deprogrammed. If it’s the case, you have to reprogram it with the help of owner’s manual.
