An audio signal system for a vehicle remote locking mechanism provides an audio signal that is more intricate than a simple, sounding of the vehicle's horn or beep tone. Preferably, the audio signal may be varied among many possible sounds by the operator. More preferably, the system includes a digital audio source with a signal amplifier and loudspeaker. Most preferably, the digital audio source is programmable with recorded sounds that can be transferred from a remote bank of digital sounds, for example by being downloaded from an internet website.
