Vehicle security system responsive to short and long range transmitters

摘要

A vehicle security system that includes a receiver/controller which may be installed on all vehicles on a dealer's lot and "taught" to respond to a low power short range "dealer" transmitter prior to sale and to a conventional relatively high power long range "customer" transmitter after sale. The short range transmitter permits a salesman to demonstrate the security system as a natural adjunct to the sale of any one of all the vehicle on a dealer's lot without affecting the state of security of other vehicles in the vicinity. The controller can be taught to respond to either a dealer or a customer transmitter but all dealer transmitter ID's are deleted when teaching a customer transmitter ID and vice versa. In addition only one dealer code can be stored at any one time. A removable valet switch is operative after sale of the vehicle to permit override of the system. Prior to sale the controller is programmed to inhibit operation to the valet switch. The removable valet switch and an LED indicator are housed in a single housing for convenience of installation and ease of use.
