HELP! 2007 G6 Door Locks Going Nuts!!!

So I just pulled into my job and the door locks went crazy. Locking and unlocking randomly multiple times. I had noticed before leaving that it wouldn't remote start but figured the key fob battery was low. I drove to work (no issues) and as soon as I pulled in it went crazy. Not sure what to do. Never had this happen before (original owner).

I'm loathe to take it to the GM dealership here as they charge $140 to even look at a problem. I apologize if this has been covered elsewhere but I couldn't find it.

sounds like a bad actuator.

Would that cause the remote start issue too?

Was it all four locks or just one?
If it is the actuator, they're fairly easy to replace. When I did mine, I think the dealer wanted $250 (Canadian) for an actuator, a part store was $130 and the wreckers were $30. I went with the wreckers.
Here's a video of how to do it.

As far as the remote start, I'd switch out the battery and see if it works again. That's the cheapest fix to start with. Did you drop it recently? They can be fairly sensitive.

Is it a factory remote start or aftermarket?

Doesn't sound like an actuator to me. If the actuator wasn't working or was struggling to lock or unlock then yes. This sounds more like a body control module problem. Something causing the actuator to cycle.

Okay so update...

Looks like it was the key fob. Pulled the battery from the original one (because apparently I'm dumb enough to not have though of that sooner) and the locking/unlocking stopped. Bought a new fob (and brought it to a locksmith (low low cost of $50) and it works again. Oddly though the "lock" dash light stays on while driving and chimes 3 times when I start the car. Is there some lock cycle I'm missing to correct this? Typically that dash light would only come on when I locked the door from the outside.
