I have just recently noticed that my door does not lock from the inside anymore. Meaning that when I open my door and lock the doors from the button than close the door it can still be opened. While when I am in the car with the door closed and lock it with the button it works. Any suggestions?

 

To view the entire mechanism, you will need to remove the door panel. Once the panel is off you should be able to figure out what the problem is.

 

On mine, if you lock the door from the inside, by pushing the button down, and then close the door(passenger side door only), you have to hold the outside door handle out to keep it from unlocking when you close the door.(I think that might be what your talking about)
