This device is an add-on component to an existing keyless entry system
that will play a pre-recorded sound from a speaker/amplifier system
mounted underneath the hood of a motor vehicle. Installable
interchangeable sound cards are provided to give the device the ability
to play different sounds. A digital sound amplifier is activated by the
radio frequency of the automobiles factory installed keyless entry
system. This is a novelty item and does not interfere with the cars
existing systems.
