Its pretty easy. First you have to remove the door panel and roll up the window. Look at the lock and you will see a square spring type clip....slide this off (dont pull towards you, slide it along the door). Once you do this, you will need to remove the rod from the lock. The lock will have a pivoting clip on it, it stays attached to the lock. Once you pull this clip back the lock will fall right out. It is real easy, give it a try and you will see how it is set up. Good luck. JP
