Stupidly easy to install. Seriously, we were getting ready for a trip and I though "man it'd be nice to have that in there" and it took less than ten minutes from start to finish including finding my socket set and clearing the junk out of my console. I think I should have gone with the three digit lock. After using it a little bit I don't see any real utility to the four digit. Only complaints are that the opening could be bigger (hard to get large things like full size pistols in and out) and that it eliminates the convenience tray which it would be nice to figure out some way to keep like if the whole top of the vault just came off once you opened it all the way or something. I'd also really *really* like to have a quick access biometric function *as well as* the 4 digit locks.

The console vault could not have been any easier to install and my belongings are more secure in my car!
