So I am locked out completely. Key battery died. I fixed that. Went and locked the car with the remote for the first time and I head all 4 doors actuate but none of them unlock. I head the gas tank door lock and unlock as well. That does release. Trunk will not open.

Here is the real kicker. The door key is not the one for the car. It was hit previously and did the previous owner did some DYI repairs. New fender and front suspension. I believe the replaced the door as well since the rescue key does not open the door that is on the car.

I am having a lock smith come out but I cannot find ANY wiring diagrams for the BCM to check wiring and continuity hitting the proper levels.

I would normally say its a door actuator but the liklihood that all 4 actuators are bad is slim but never 0. If there are any diagrams you guys can provide I would be greatly appreciative of it.
