How long did you wait?uhh!! i locked the car with one of the windows open and waved my hand inside the car but nothing happened .. so i am not sure if its got one .. any other clues like sensors and stuff ??? or could it be a blown fuse ??
yea i do have a button (with a pic of car showing some waves coming from roof) at the bottom of B pillar on drivers side.Has it got the "pet" button to the right rear of the drivers seat, if so you got yourself an alarm
