Abstract
A keyless vehicle intrusion alarm is armed by momentary depression of the brake pedal or actuation of some other electrically-responsive circuit, followed by the opening and closing of a particular vehicle door within a first predetermined time period. In order to signal the operator that an arming sequence has been initiated, a short burst of the alarm is sounded after the brake pedal or other electric circuit is momentarily activated. Subsequent reentry via that door initiates a time delay during which the entrant must actuate the ignition switch to prevent an alarm from sounding. Entry through any other door, or tampering with the vehicle hood, results in immediate sounding of the alarm. The alarm sounds for a limited time interval before being automatically squelched.
