I have a 2009 Aveo, and i installed the universal power lock kit from autoloc.com. They have a couple of options, you can get just the actuators and wiring harness or you can add the keyless entry. I have the kit with the keyless entry, and i installed it about a year ago and it still works great! Probably the hardest part was installing all the actuators and getting them mounted right, but all in all it wasn't too difficult.
