It looks like they took the bezel and pushed it through the lens. Then they cut off the pins an mashed them so that the lens can't be separated easily.
Anyway, I did mine by taking a dremel and carefully removing the excess metal from where they pinched the studs off on the bezel. I got enough metal off that I could carefully remove the lens from the bezel. Then, I took the bezel and had it re-chromed. I used an epoxy to re-attach the bezel to the lens. I haven't had any issues with them coming loose and I drive the car frequently.
