The Gun Vault that Mossie pictured in her comment is the one I have and got it from Amazon also. It is really great. My truck doesn't have a lock on the glove box or console, so this fits nicely into my console and the cable goes arounf the seat mount. If I wanted to use it in my car, I just unloop the cable and reloop in my car and I'm ready to go. I perfer the key lock to the combo lock. I keep the key on with my Ignition keys on one keyring so I always have it with me in either vehicle.
Safety note: Never keep your door key and auto door lock opener on the same keyring. I did that when I first got this truck and forgot and locked my keys in my truck. I had to call m y wife to bring her keys to get me back into the truck. I keey my door opener on a seperate key holder on my belt now, so if I should hit the door lock button and lock myself out, I can just hit my auto door lock opener and get back in. I have asked many people how they expect to get into there vehicle if they have their keys and door lock opener on the same ring. They said they never thought of that. I learned the hard way. Hope you don't.
