I bought two little steel gun safes from Academy, one for my vehicle and one for my wife's. They come with two keys (they do have combination ones) and a cable for securing to the vehicle, I use a bar that's part of the seat or the mounting bracket for the seat. I always put my handguns in the safe if I must leave them in the vehicle, and I try to hide the safe under a seat or in a console. I recommend that everyone use a safe that's secured to the vehicle even if its in a trunk, most cars have a trunk release button so crooks need only bust out a window push the button and their in your trunk, so a trunk is not secure. No safe is entirely fool proof but will slow them down if not simply just deter them from even trying.
