LOL! I did come home one time and the keyless entry didn't work. The battery had died. My partner Misha panicked because she is the panicking sort. I said, "Calm down! The upstairs bedroom sliding glass door is unlocked, isn't it?" She continued to panic, "Sure, but how are you going to get up there?" I said, "I'll just use this extension ladder laying right here on the deck." And I did.
