Patent number: 5563453Abstract: A method and apparatus for remotely controlling one or more vehicle functions. The method includes providing a first coded signal transmitted by a cordless transmitter. The signal is received in a receiver located in the vehicle. The receiver includes a decoding device to detect and identify the code and to compare the signal code with a vehicle specific code. When agreement is found between the received code and the vehicle specific code, the receiver activates one or more electronic circuits in the vehicle through the agency of a control circuit, such as to deactivate one or more of the vehicle functions. The method also includes transmitting from the cordless transmitter a second coded signal which results in the activation of those vehicle functions that were earlier deactivated.Type: GrantFiled: August 31, 1994Date of Patent: October 8, 1996Assignee: Scarinus Development ABInventor: Leif Nyfelt
