The lens will be easier to remove if you remove plastic cover first.
Gently remove it using a plastic prey bar. 
It should pop out easy. 
As an FYI, there are plenty of plastic pray bar kits on eBay. 
It's a very inexpensive tool, and must have, if you are working on your car.
If you have a rattle noise, it might not be seated fine, or one of it's locking tabs is broken. 
As far as I know, it's not an expensive part to replace.
