An anti-theft ignition system including a generally tamper-proof canister or housing substantially covering the solenoid of the starter motor with a portion thereof covering the ignition switch terminal of the solenoid. The housing includes a compartment for receiving electronic circuitry including an encoded circuit coupled to or forming a part of a microcomputer operable in response to proper sequential actuation of the ignition key for energizing a silicon controlled rectifier in series relation with the ignition switch.

In a system for a vehicle having a switch means which is key operable from a first position to a second position for energizing the electrical system of the motor means of said vehicle, the combination comprising: means for detecting momentary actuations of said switch means for generating serial pulses; means operable in response to the last pulse of a number of sequentially entered pulses for indicating completion of a word; means for providing a vehicle condition-sensing signal; means for providing a plurality of words indicative of a given code; means for enabling an electrical component of the vehicle for permitting the starting of the motor means; and means responsive to said signal and to proper sequential entry of at least a portion of said plurality of words for setting said system for permitting subsequent energizing said enabling means only in response to proper sequential entry of all of said words for operating said motor means.
