There is a ghost in it. Get a old preist and a new preist and chant "the power of christ compels you" over and over.

This will not stop the beeping but it will be pretty awesome and may make the beeping a bit less annoying.

OK seriously, do you have comfort access? If so you may have the key too close and if you have the car set to auto lock after not being driven for x minutes it is possible this is unlocking and relocking I suppose, just a thought to try and get the ideas going.

Good luck
