If so, like most trim, its a 'gentle' pull. The trim is simply pressure fit over the door bottom, BUT, may be difficult to remove cleanly if rust has deteriorated the bottom of the door. Unless in pristine condition, these trim pieces will be garbage once removed. Hopefully the rust is managable and you can do some spring cleaning, take care of the rust and just replace the trim. There are many write ups here about the process.
Good luck with it,
