Hi All, intermittently the car key code light comes on and air bags light comes on my wife's 2006 Mazda 3. It also flashes and bleeps every so often. Taken it to the Mazda dealer who played about with it all day, but could find the problem( 250 charge). Told that they may have to change a major component at about 2000 dollars plus labour to fix the problem. Does any one know what the problem might be??? Car still runs, lights only come on when open the car door. Once locked then it goes quiet. Thanx Stevie.
