Yeah, I have a keypad and remote to open the overhead garage door but, in the event that the emergency occurs during a power outage, I'd rather have a key available. The lock box seems the easiest solution so long as the combination can easily be conveyed to emergency personnel.

My most immediate concern is for an elderly family member who recently took a bad fall. She would have been very hard pressed to unlock the door and it was just plain good luck that I was there to handle the situation. I don't want to eliminate good luck from the equation but I sure don't want to rely on it.
