What does it means when my Theft System light is constant on all of the time. What is wrong with my car? I have a 2003 Malibu ls, 4 door, power everything, keyless entry. Is there something major or minor wrong when this is showing.

What does the owner’s manual have to say?

Check the owner’s manual, or operation manual for an aftermarket alarm. Some systems do leave the light on always. Chances are, tho, it is requiring some attention. I think the manual will suggest you take it to the dealer so they can diagnose it. I really cannot offer an alternative, since most manuals I have do not cover the theft deterrent system.
