I really don't post much here, but I thought this might be helpful to some people.
Backstory:
In August, I was at work and my wife got off work early. She worked out in the garage, left it open, and went inside. Two guys stole a gas can (Non-CARB compliant Jerry-can, damn them!) from our open garage. Filed a police report, but didn't catch them. We live in suburbia, surrounded by other Marines. I put one of those battery-powered key coded garage door remotes outside. Funny enough, after this happened, the whole block bought them. Well, I worked out on Tuesday night, Crossfit stuff, sprint around the block, come back, etc, etc. All of the doors were locked, and I keyed in the code to shut the garage door. When I came back and keyed in the code, it just blinked and wouldn't open. I still don't know why, dead battery, some kid messing with it, or whatever. I had no key on me, but luckily I was able to use my hide-a-key from the truck to open the truck and use that garage door opener to open the door. I wasn't worried about getting back into the house, because I have a house key inside of the gun safe, which is in the garage.
Fast forward to Friday, when I was getting my DOD decals renewed. I noticed a small key box with a simplex-type lock in the PMO office. I found one at Lowe's, for about $30. It's called AccessPoint, by GE. It's a metal box, about 3"x2"x1" that can hold two keys. I bought it and installed it underneath my deck using 3 1/2" decking screws, not the little 1" ones that come with it. It's probably better than dropping a key under a flower pot, but I sure wouldn't mount it where it can be seen or pried at. It's a pretty hefty little box, and I think that it might be of good use to some of you as well.
