WHAT LOCK ? ENGINE, DOORS, TRUNK, GLOVE COMPARTMENT, HOOD, WINDOWS, OR YOUR WIFE SITTING NEXT TO YOU ????????? AND WHAT IS MEANT BY 'AUTOMATICALLY' ?
because there is a problem with your anti-lock brakes
Turn the ignition key on for 10 minutes and it will reset.
Drain radiator through plug at bottom or rear of radiator Re-fill radiator with a 50/50 mixture of antifreeze and water slowly to prevent an air lock
On the 2004 4-door Alero (cannot vouch for any other year or body type) the driver's door switch is integral to the door-lock mechanism. You must remove the door panel to access this mechanism.
I had a similar problem about a month ago on my 2000 alero. You need to get your Anti-Lock Brake system checked. Any decent auto shop has the ability to do the check. Either one of your ABS sensors is bad (which means replacing that wheel hub), the wiring between the ABS CPU and the sensor has deteriorated, or there is a problem with the computer that controls your ABS system (which was what happened to my car).
Many of the newer vehicles automatically lock the doors when the vehicle starts to move. Some have provision to disable that feature, but most do not.
Probably a problem with you key being worn and the theft lock system not recognizing it, so it thinks you are trying to steal you car because the key is not an exact match to what is programmed into the ignition switch, thus grinding but it will not start!
