Quoted from Oneangrymo:
Man I’m having a hard time removing back glass to access the back box , don’t u just turn the key and lift the translite up ? It doesn’t even budge any help ?
I've had this happen on a couple of pins. Either it is getting stuck to the paint, the trim doesn't fit well, the lock isn't turning properly, or there is some type of debris blocking it.
Make sure the key fully turns. You can use graphite if it isn't.
Try gently sliding one side of the BG upwards, and then try the other side.
You can also try sliding the BG left or right...very gently, of course.
If it is debris, you can take a hand-vac and go around the edges to suck up any wood, glass, etc.
