Wireless anti-lockout system
First Claim
1. A wireless anti-lockout system for automatically unlocking a driver'"'"'s side door, comprising:
- a plurality of door-lock sensors, each of the sensors generating a door-locked signal when a corresponding door lock is locked;
a trunk-lock sensor generating a trunk-locked signal when the trunk is locked;
a manually-activated trunk button for generating a trunk-locked signal when the trunk is open;
means for generating a key signal;
means for detecting the key signal and generating a key-detected signal;
an occupant sensor for generating an occupant signal when an occupant is absent;
a door lock control for locking and unlocking a door; and
means for receiving the door-locked signals, the trunk-locked signal from either the trunk-lock sensor or the trunk button, the key—
detected signal, and the occupant signal and for activating the door lock control to unlock the door when all of the signals are detected.

Abstract
The wireless anti-lockout system automatically unlocks a driver'"'"'s side door when the driver locks the car keys within the car. The anti-lockout system includes door-lock and trunk-lock sensors, a key chain transponder, transponder sensors and an occupant presence sensor. When the doors and trunk are locked, the key chain transponder is detected in the car, and an occupant is not detected, signals are sent to a microprocessor, which alerts a door lock control to unlock the driver'"'"'s side door and activates an alarm. Additional sensors may be added. The system may include a transmission sensor and a driver detection sensor, so that when a driver is not detected, or when the transmission gear is in park or neutral, in addition to the other three signal conditions, the door lock control unlocks the driver'"'"'s side door and an alarm is activated.
