I have an external garage, with a manual overhead door (no powered opener). There is no side access door.
After the recent winter, I tried opening the garage again, and the handle will not turn. I believe the lock is disengaging, as I hear a 'click' when I turn the key. The lock is below the handle, separate from it. I tried tapping the handle with a hammer lightly, but didn't want to strike too hard for fear of breaking my only possible entryway.
Is there reasonable any way to get in, or do I need a professional? And if I need to call someone--does it make more sense to call a locksmith or a garage repair company/specialist?
