I'm not sure I fully understand what you're saying, but if by "push pins", you mean the 'dots' on the side of the panel, you need to pull those out. Once they are out, you'll need to fit in an allen wrench. The 'dots' are covers, there's a hex bolt that needs to be loosened inside. In the bezel are two "fingers" with forks on the end. The hex bolts screw through the forks and hold the fingers in place.

It's one of those things that make sense once it's all apart.
