Abstract
The power door lock interlock circuit senses the presence of an ignition key in the ignition and also senses when a door is open. When these conditions are met, the power door lock is placed in an interlock condition whereby pressing the power door lock button causes the horn to sound instead of locking the doors. The circuit is thus useful in preventing the driver from accidentally leaving the ignition key in the ignition and accidentally locking all doors. All doors may be unlocked in the usual fashion and all doors may be locked in the usual fashion provided the interlock condition has not been met.
