Abstract: A door valet utilized by the driver of a motor vehicle to unlock vehicle doors by raising the door lock button while the driver is seated in a driving position. The door valet includes a long handle, to be held at one end by the driver, and has a lock-button engaging portion at the opposite end. The lock-button engaging portion includes a pair of transversely spaced apart cam surfaces inclined toward the distal end of the door valet and separated by a slot with the slot being wide enough to accommodate the door lock button stem but not wide enough to accommodate the enlarged head of the door lock button. Upon horizontal movement of the apparatus by the driver toward the door lock button, the cam surfaces elevate the door lock button to an unlocked position and the slot accommodates vertical movement of the door lock button stem.
