Intermittantly when I use my Advanced Key Entry/Ignition to lock the doors of my new 2006 RX8 I get about 20 beeps. I've checked the windows, doors, trunk, etc. Everything locks up, I just get the beeps. Any idea what could be causing this?

 

Found the problem : Dealer left the "non existent" second key card wedged between the passenger seat and console. Advanced Key system beeps for about 10 seconds if the other key card is left in the car when it is locked.
