i noticed my alarm wasn't activating so i check'd all the doors, all my doors lock except the rear passenger door, its stuck on a open position, and the pin wont go down for nothing not even if i push it down, any sugestions? Actuator or the pin is just stuck?

 

O yea its a 3gen tl

 

I have the same problem in my drivers side door. Took it to the shop and they said it was the actuator and something about resetting it.
