Vehicle security system responsive to short and long range transmitters
First Claim
1. A vehicle security system comprising a vehicle mounted receiver, said system further including a controller for arming and disarming the system in response to receipt by said receiver of a valid code from a remote transmitter, said controller operable in a learn mode to store in memory a code received by said receiver from a first transmitter and to remove from memory any previously stored code representing a second transmitter, said controller responsive to operator actuable input switch means, said controller programmed to respond to different sequences of operation of said switch means for overriding a security system function depending upon whether said controller has been taught to respond to codes from said first or said second transmitters.

Abstract
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.

- 7. A vehicle security system comprising a vehicle mounted receiver, said system further including a controller for arming and disarming the system in response to receipt by said receiver of a valid code from a remote transmitter, said controller being programmed to respond to operation of a switch for overriding a security system function, a switch holder containing said switch and including a manually operable actuator for controlling said switch, said switch holder supporting terminal means electrically connected with said switch, a switch holder support housing mounted in the vehicle passenger compartment for removably receiving and supporting said switch holder and establishing electrical contact with said switch, conductor means supported within said housing for electrically connecting said switch with said controller.
- 9. A vehicle security system comprising a vehicle mounted receiver, said system further including a controller for arming and disarming the system in response to receipt by said receiver of a valid code transmitted from a relatively short range transmitter or from a relatively long range transmitter, the code transmitted by said relatively short and long range transmitters having a unique identification number and having a further characteristic which is detectable by said controller in order to determine the origin of the transmitted code, said controller operable in a learn mode to store in memory a code received by said receiver from said long range transmitter and remove from memory any previously stored code from said short range transmitter and further while in said learn mode to delete all previously stored long range and short range codes in response to receipt by said receiver of a code from said short range transmitter and store the received code from said short range transmitter.

15. A vehicle security system comprising a vehicle mounted receiver, said system further including a controller for arming and disarming the system in response to receipt by said receiver of a valid code transmitted from a relatively short range transmitter or from a relatively long range transmitter,
the code transmitted by each of said relatively short and long range transmitters having a characteristic which is detectable by said controller in order to determine whether the code originated from said short or said long range transmitter, said controller including a memory for storing either a code from a short range transmitter or a code from a long range transmitter, said controller being programmed to prevent simultaneous storage of both a short and a long range transmitter code and further programmed to respond to a plurality of input devices which provide an input related to a function of the security system when the code of a long range transmitter is stored in memory, said controller further programmed to inhibit at least one of said functions when the code of a short range transmitter is stored in memory.
