Q: Alarm system on; car won't start

The factory theft deterrent system can be frustrating, as it prevents the owner from driving their own vehicle when it is activated. With your Chevy Malibu, there can be a few different reasons that can cause this, such as a faulty ignition key or a faulty switch. One thing you can attempt to do if you need to move your car right away, is to put the key in the ignition and turn it to the on position and leave it there for 10 minutes, then start your Chevy. This should bypass the alarm so you can use your vehicle. I would recommend enlisting the assistance of a certified mechanic as soon as possible to come by. They can identify the exact cause of your faulty theft deterrent system so they can make the repairs needed to allow to start your Chevy worry free every time.
