KAK, I can't begin to tell you how very sorry I am to hear that your safety and security has been compromised. When we got home from church on Palm Sunday, Mike found that a rock had been thrown through a window of our back door. There is a deadbolt there but it can only be opened from the inside with a key that we remove when the back door is not being used. There is no latch there to unlock the door by reaching inside so whoever did this couldn't get in. Maybe a similar lock might work for you too.
