  • the present invention relates to a vehicle adjunctive security system for use as an adjunct to a vehicle security system, and more particularly the present invention relates to a vehicle adjunctive security system for use as an adjunct to a keyless vehicle security system.
  • intruders would need to either (i) steal the car key from the owner, or (ii) breach the vehicle in another manner, which may or may not be required if the vehicle was unlocked which may require to physically damage the locks or windows in order to break into a vehicle, (iii) often disable an audio alarm device which may require quick action before undue attention was drawn, (iv) physically overcome a steering lock mechanism, and (v) start the vehicle typically by “hot-wiring” the ignition system.
  • keyless vehicles are widely used, access thereto can be controlled remotely, within a certain range of the vehicle, by simply pressing a button on the remote fob, or by being within short-range RF reception ranges in order to unlock and activate the vehicle for some vehicles.
  • the remote fob of a keyless vehicle contains a short-range radio transmitter which emits a radio frequency with a designated and distinct digital identity code to the receiving unit of the vehicle, when it is within certain range of the vehicle, usually 5-20 metres, or possibly less depending upon arrangements and conditions such that the vehicle can be activated or deactivated.
  • a wireless fob can be effectively cloned at a distance by a criminal.
  • Car thieves usually operate in pairs, with one of them waving the relay amplifier around the perimeter of the house in which the wireless fob corresponding to a vehicle the thieves wish to steal is considered to be located within, especially near windows and doors for seeking to pick up the signal emitted by the remote fob that is placed inside the house.
  • the signal is picked up by the amplifier, which will then be sent to the accomplice’s transmitter, which then effectively becomes the key to the vehicle. This then effectively tricks the vehicle into thinking that the real key is nearby, whereupon the thieves are able to activate the vehicle and drive away, typically without anyone noticed and with any anti-theft system being disabled and without any vehicle alarm being invoked.
  • intruders do not need to physically unlock the vehicle with an actual mechanical key, do not necessarily require physical skills or techniques or mechanical theft tools, but simply copy the radio signal sent off or transmitted by the remote fob device, and such a process is very simple, does not damage the vehicle due to breaching the vehicle, does not require disabling of security systems or manually starting ignitions system or a key which has a short ranger transponder, as an effectively cloned fob gives the thief unfettered access to the vehicle until it is noticed as having being stolen, by which time the vehicle may be broken down for parts, any GPS location system being disabled, and the vehicle is long since gone and irrecoverable.
