How do you take apart the 23+ keys?

I've taken the two side trim off the key, try to pry it in every direction but can't get the shell to come apart to get to the board.

Hopefully it's what you're looking for.

Thanks the pre-23 keys are different and really easy to take apart but the  newer key have an additional shell that appears to be glued to the front cover that is impossible to take apart. GM can't be this stupid right? First they take our ability to program additional key away and now make it impossible to replace the cover.

Or maybe it was intentional

Why?  What's wrong with the factory key?  

 

EDIT.  Let me guess.  Bought one of those AJT Design cases (which doesn't hold the emergency door key BTW)?

 

Did you try...AJT's website?  Which has a how to video to take those apart?

@newdude I didn't even know anything about the AJT case until now. That video is extremely helpful for what I need. I'm not only changing the case. I bought one of those LCD key, it solders a couple wires onto the existing button pins to the original remote. The thing I was most interested in was the approach unlock that I have on all my other vehicles. On the 23+ GM cheap out and removed the unlock button from the back doors. With impatient little kids they'd get to the door before me and start yanking on the handle. LOL

A little update- This was the key I purchased.

 

I'm happy to report that after soldering all the wires to the new remote, I have all the factory function as intended. Since the new key has 4 dedicated hard button only and ours have 5, I decided to use the "panic" hard button for the remote start. 

 

in order for the key to do the unlock on approach, there's an OBDII adapter that needs to be plugged in. The problem is I believe the OBDII port does not have power until the door is open so this is beating the purpose. I'll have to figure out how to keep the OBDII always on.
