Mine came with 3 keys & 2 remotes. 2 black keys, 1 grey. The grey works in everything but the glovebox and tailgate.
This allows you to leave that key with a valet, so they can park the truck and lock the doors, but they can't unlock anything else for safety if you want to put something in the glovebox. (or bed if you have a cover)
