Abstract
A vehicle security system includes a controller for permitting addition of a coded remote transmitter capable of switching the controller from an armed mode to a disarmed mode, and generates a signal based upon a number of coded remote transmitters capable of switching the controller to the disarmed mode. The remote transmitter verification is preferably communicated to the user by flashing a dashboard mounted light a number of times corresponding to the number of coded remote transmitters responsive to turning vehicle ignition to the on position, and when the controller is in the disarmed mode. Accordingly, the user is ensured that only the coded transmitters under his control may operate the vehicle security system. The controller may also enter the disarmed mode responsive to receiving a predetermined coded signal from a remote transmitter, and generate an alarm based upon receipt of a coded signal other than the predetermined coded signal from the remote transmitter. More particularly, the coded signal may comprise a pseudorandomly coded signal which is decoded by the controller. Method aspects of the invention are also disclosed.
