I work on garage doors. If your door has windows they will punch the window and pull the release cord. If you do not have window they will push in the top of the door( it will flex 2-3 inches) and fish for the release with a coat hanger.
Not recommended because of fire entrapment but you could wire your release closed and cut it away if you need to open door manually.
Or purchase a Liftmaster 3800. This motor rocks because it is side mount and has a sliding bolt so it would be extreamly difficult to get inside.
Thanks for the heads up on delivering bikes I have a ltz 400 for sale now and I have delivered to Craigslist customers in the past ( no issues).
