Abstract:
A theft prevention device for a vehicle having an electrical system and a power supply, the theft prevention device comprising:an â€œarmed statusâ€  to prevent theft of the vehicle; a remotely activated latching relay configured for movement between a first position and a second position, said remotely activated latching relay connects the electrical system to the power supply when said relay is in said first position and said relay disconnecting the power supply from the electrical system when said relay is in said second position, said second position corresponding to said â€œarmed statusâ€  of the theft protection device; a bypass circuit being configured to connect the electrical system to the power supply, said bypass circuit allowing a current from the power supply to reach the electrical system when said remotely activated latching relay is in said second position, said current being less than the current traveling through said remotely activated latching relay when said relay is in said first position, said current being in a range sufficient to maintain volatile memories of electrical components in the vehicle; and a hand-held transmitter being configured to remotely activate said latching relay.
