Valet switch is much like a valet key... it won't let people enter the glovebox or boot. So when a valet parks your car, they can start it, drive it, but not swipe anything in your boot and glovebox. (prolly not applicable for Skylines... no lock on the glovebox)
since when does a skyline not have a lock on the glovebox, mine does?r33 96 na
HMmmmm maybe its an aftermarket lock hehe
