  • Check your garage door sensors to ensure that they are always in good working order. The condition of your garage door sensors will determine how smooth the garage door works.
  • Lock your garage door! Never drive off before you ensure that your garage door is locked. Stay and see that the garage door completely shuts.
  • For maintenance of your garage door system, go to trusted professionals for any repairs whatsoever. Have monthly or bi-monthly inspections of your garage door and its locking system.
