Abstract
A vehicle security system disables various electrical systems throughout the vehicle. A unique double-sided security key is used to complete the various circuits of the chosen electrical systems by matching physical codes on the key to that of an installed receiving unit mounted within or about the dashboard of a vehicle. The various combinations created by the coded key make a determination of how the various circuits are broken. The method of attempting to re-connect the circuits by trial and error is prohibitive to a would-be thief. The unit can be used to disable an automobile, boat, motorcycle, RV, etc. The device may include one or more blocking diodes within the circuits to produce false readings during attempted tampering.
Claims21
A vehicular security system comprising:
- a key having a first and second side;
- said key having longitudinal contacts;
- said longitudinal contacts selectively connectable on each of said first and second side in a first connection;
- said key additionally comprising one or more feed through holes for selective connection of said longitudinal contacts between said first and second side in a second connection;
- said first and second connections being arranged in a plurality of predetermined configurations, said configurations corresponding to a plurality of unique security codes;
- a key receiving means, including receiving contacts, for receiving said key;
- said key receiving means connecting one or more electrical devices located within the vehicle;
- said key containing at least one of a plurality of predetermined security codes, and
- wherein said key is selectively inserted into said receiving means to form an electrical connection between vehicle electrical circuits.
A vehicular security system comprising:
- a double sided security key comprising a plurality of longitudinal contacts with feed through hole connections connecting a first and second side of said double sided security key;
- said longitudinal contacts and said feed through hole connections being connected in various configurations to encode the key;
- a key receiving means, including receiving contacts, for receiving said encoded double sided key;
- said key receiving means selectively completing a circuit of one or more electrical devices located within the vehicle by reciprocally mating the contacts of said encoded double sided key, and
- wherein said key is selectively inserted into said receiving means to connect vehicle electrical circuits.
A vehicular security system comprising:
- a security key comprising one or more printed circuit boards having contacts on each of a first and second side of said security key with feed through hole connections;
- said contacts on each of said first and second sides of said security key being connected in various configurations on each side and between sides to encode the key;
- a key receiving means for receiving said encoded key;
- said key receiving means selectively completing a circuit of one or more electrical devices located within the vehicle by reciprocally mating the contacts of said encoded key,
- said receiving means including at least one blocking means to produce false readings during tampering, and
- wherein said key is selectively inserted into said receiving means to connect vehicle electrical circuits.
