The doors do not lock or unlock with the transmitter if the ignition key is inserted in the ignition switch.

Need a tech 2 scan tool to turn it off

Try spraying a penetrating spray (WD-40 or similar) into key holes on door, and up into latch area. You may have to do it numerous times before things will loosen up. You may need to remove the door panel, to ensure that you've loosened up all the pivot spots on the linkages but I would certainly make sure the linkages going to the locks are all moving freely before I change a power lock motor. Sometimes spraying the lube, and assisting the motor by manually lifting/pushing down button at same time as flipping the switch, will aid in loosening it too.
