ABSTRACT:
A pushbutton controlled locking arrangement for a door or other entry, as a trunk lid, to a vehicle which selectively activates circuitry for achieving unlocking upon the engagement of a preselected combination of pushbuttons presented in panel form. The circuitry includes conventional components, such as single-pole and double-pole double-throw relays, electrolytic capacitors, a variable resistor, pushbutton type switches and silicon diodes, all arranged for convenient operation without the necessity of a key. The aforesaid pushbutton panel is typically mounted on the vehicle body proximate the door handle area and affords reliable usage through weatherproof pushbutton switch assemblies.
The system also makes provision for illuminating the pushbutton control panel, the initiation of an optional alarm signaling arrangement in the event of unwanted attempted entry and, as well, overriding control when two pushbuttons are inadvertently depressed at the same time.
