Interesting post - I've thought about putting a lock box out there several times ... But, as has been pointed out, that's where I also keep tools. I have thought about this more than a few times - and decided that I'll just use my EDC. I go out, early, every workday morning and use this routine: (feel free to laugh if you want) Exit house, and lock door into house, get into car and lock door, open garage door, start car and back out waiting for SHMBO. Ditto for coming back to the garage alone - but have to let her out when she returns cause our garage is small & she can't open door. Either way, I have an EDC with me every moment I am outide the house. I can't believe how many times I've read or heard about the potential for thugs to follow a car into the garage when someone returns home - all I can say to that is a person needs to maintain their situational awareness, and watch for that, before exiting the car.
