okay, now since I do owe the Guppie (sunfire) and DO NOT HAVE ALL THE GREAT FEATURES the GRAND PRIX. When you go out to start the Piranah, locks are eletric (no manual pushie), the button on the door pannel just does not respond when you try to re-lock the locks. EXPAMLE:If you wanted to go warm up the car, but can not really leave the car un-locked and unattened. If you had another key to open door with, you could get out an lock the doors and go back in the house, ect. ect.. ect...NOW problem here is cant do this in the Piranah, you start car, get out and push lock to re-engage the locks. NOT HAPPENING HERE. But once car is warmed up you can lock and un-lock all day long.
