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.
