Removing Front Spoiler - Help

Hello,
I'm looking to replace the front spoiler on my 451 2013 Smart Car.
Right now, I have the black textured spoiler, and I want to replace it with the smooth black spoiler.
Part Number- 4518850225CA7L

Can I remove just this piece? Or is it required that I take off the whole front end?
If I do have to take off the whole front end, how hard is that to do?
I removed the door panels one time to fix a broken window, and it took me hours to get the door panel back on correctly.
Not sure if I can emotionally handle that again, haha.
Thank you!
