Are the bottoms of your keys NSFW?
Ditto, David Crandall. Been using number pad door locks since my kids were early-teens, losing house keys every other week. WELL worth the investment. Office is keycard. Car is keyless ignition. Much lighter in the pockets.
I do carry full size Gerber EOD multitool (my preference, the C4 punch is invaluable) and AA Led flashlight in laptop bag, and another set in car, but do not carry them on me.
