Every time I try to lock my doors on my car, it's makes the ringing noise that its supposed to make when you try and lock your doors when a door is open. It was working just fine yesterday
and I went to go lock my doors when I got to work and that's when it started doing it. I checked and confirmed that all my doors are shut and my hatch is closed correctly.

Any ideas??

Try disconnecting the battery so the module resets. It may be possible that it stills see's that one of the doors is open, it is an electrical component after all and can have a glitch.
