Nothing, It doesn't respond when I try to stop the alarm by turning it in either direction or by locking both doors back or unlocking again. When we bought the vehicle 12 days ago the red alarm light on the door lock was not on or blinking even when the door was locked and the alarm was not sounding at all. It didn't start alarming until I locked the door,went in a store, returned to get in the car, turned the key cylinder the wrong way several times trying to unlock it and the red light starting flashing. When I turned it the right way to unlock the door and opened the door the alarm went off and I couldn't deactivate it. It stopped after 20-30 seconds. Since then we have had the problems. At first the alarm would go off by opening the drivers door, then that stopped and it would only go off when the ignition was turned on, that stopped and I thought it had reset until I opened the passenger door. Since then it only goes off when the passenger door is opend, when the hood is opened or the trunk is opended.
