2007 Nissan Xterra car door

If the door won't open from the inside or the outside then there is no simple method to use. Even the dealership will have to literally pry the door panel off and may even damage it in order to gain access to the inside of the door. There isn't any other way. Once access to the door is achieved many times the latch itself often will have to be broken apart to get it to release. Then replacement of latch will be required.
