You just have to mess around with a small screw driver to pop it open. You tube has a few videos about this. I spent 20 minutes just sticking the crew driver in the slot and moving it around and it finally opened. Installing new latch is SIMPLE.
I got mine done yesterday. Key fob didn't lock or unlock the truck for about 2 hours after, but that came back too. We have never had any trouble with braking so I didn't expect to feel a difference and there was none.
