Okay so my passenger front door is stuck shut and won't open from the inside or outside. I've already removed the door panel as much as I could and could see the door lock actuator. I was able to get a long flat head down there and push the door opening mechanism but still no luck. The door is jammed shut! Now what I was thinking of doing was just breaking the plastic cover to the actuator just enough to open the door and replacing it? I would really like to get some advice as to know where I should go from here. I've researched this a bit and it seems to be a common problem with these models. I'm pretty sure someone here as experienced this same issue. Thanks in advance fellow Lexus drivers.
