Most likely this is the shift interlock. What that does is tell the ignition switch that the vehicle is in park and it is ok to release the key. Basically it thinks the vehicle is still in gear so the key wont come out.
Let's start with accessing the actuator and checking voltage when the vehicle is in park. You can try to manually push the actuator down to see if it makes better contact. Sometimes they just make poor contact and other times there is an actual wiring issue. However, I am sure your issue is with this.
