Drivers door plastic surround of the locking button

[malleefowl]

Hi all,
I need to remove the door skin to get the window back in it's track.The handle etc seems easy but that surround of the door locking button has me stumped.The book simply says to prise it off.Don't want to wreck it- there must be a trick to it
Can anyone help
Thanks ,
Mary

I use something broad but blunt (like an old 1" chisel),placed against the bottom edge and then bash chisel handle upwards with fist. Always works for me, and the suround is still reusable. Don
