The remote will not unlock or lock any doors. The button on either front armrest will lock and unlock all doors. Would this be the dreaded actuator or something else? Remote has new battery in it.

You can have a problem like I did where the car lost all programming of the remote so it will not recognize it for its features. I found out when I took it to the dealership after having it programed 4 months prior by an independant.

Well, I have 2 remotes and neither work. They will unlock the trunk, but will not lock or unlock the doors. The inside lock switches work fine on both sides. I'm just trying to figure out if the inside switches work off the actuators as well or something different.

Not sure what is wrong so I can fix it.

it is possible your remote ecu (that is located in the passenger rear c-pillar has gone bad) i HIGHLY doubt all your actuators went out at the same time although it is problem
