Method and apparatus for vehicle security system

A vehicle security system includes a vehicle anti-theft controller (12) in communication with an identification system (14) and a power distribution system (16). The power distributing system limits power to the ignition system starter motor (22). The power distribution system (16) supplies power at various levels in response to commands by the vehicle anti-theft controller (12). In an unarmed state, the starter motor (22) is operable when the power distribution system (16) provides a first power level thereto. In an armed state, a second power level, which is typically much lower than the first, is adequate to operate the identification system and vehicle accessory systems but not the starter motor.
