Just a note that some states, SC included, require the storage of a firearm in a separate and locked area of vehicle--ie: console, glove compartment, trunk, unless you are CC, in which case, as long as firearm is on your person, you can CC in car. Obviously, once firearm is not on you it must be locked in separate area of vehicle--cubby hole, under seat, makeshift whatever hiding etal is illegal, lockbox is.
SC SECTION 16-23-20 says you can carry a gun in the console, glove compartment or trunk that needs to be closed. It does not need to be locked. A lockbox is not illegal in SC, as long as it isn't under the seat and is fastened to the car in some way.
