Abstract: An apparatus and method allowing a first communication distance between transmitter and receiver for substandard short range control of a vehicle security module, and a second communication distance between transmitter and receiver for standard long range control of the vehicle security module. In this manner, the receivers of numerous vehicles may be programmed all to respond to the same common code, and the short range control used to activate only the vehicle(s) immediately proximate a short range transmitter. Thereafter, the receiver of a selected vehicle may be programmed to respond to a unique code, and the long range control used to activate the receiver of the selected vehicle at a longer distance from a long range transmitter.

Abstract: An antitheft system for use with a vehicle. The vehicle used with the system has a battery for providing a constant voltage source and a ground reference, and an electrically-controlled operational feature, wherein activation of the feature is necessary for operating the vehicle. The system includes a first harness connector with a plurality of contacts for connecting to a second harness connector having corresponding contacts. The second harness connector is connected to a security module having antitheft functions. The plurality of contacts of the first harness connector includes a first contact for connecting to circuitry in the vehicle for providing an activating signal to activate the operational feature. Also included is a second contact connected to a terminal of the electrically controlled operational feature, where the terminal is for receiving the activating signal to activate the operational feature.
