You'll need to get onto Ebay and those sites to see how that Grille works.
It's not like YouTube "Tear off" vids, those are EU models that they do that to..
In the US, they've got "bolts" that screw onto the front cover that go into the front fenders - that's how the grille stays on the vehicle - else others would have ripped them off a long time ago and you'd be using chicken wire to keep out the birds insects and squirrels that all get sucked up into the radiator.
You have to remove that front cover, then you'll see how they use "tab to Tang" inserts, you place the Grille in, then the chrome trim, fits over and snaps it into place on the grille. The tabs expand into the tangs, and that is how it's held in place.
So to remove that grille to even change the insert, you'd have to take apart that front "skirt or apron" yes, the entire thing, which houses the Fog lamp, lower bumper grille and Front grille. In order to gain access to those tabs
Then you have to bolt the whole mess back on.
There's a few You tube vids about how they approach the concepts of removal of that front cover, to obtain access, then reinstall - it's a little tricky and not easily done using one person.
Here's a link to the
