Changing out threshold?

Hello,

My wife wanted to change the front door threshold from brass to silver. I purchased the threshold at Lowe's expecting a simple process. However, when I unscrewed the old threshold I noticed it is under the side molding running on opposite sides of the door framing. What is the best way to remove this molding without causing significant damage to the boards. I attempted to pry off the side molding boards with a hammer and flat head screwdriver but the boards did not seem to respond very well.. they looked like they wanted to give way and crack.
Any ideas/tips on the best way to remove these boards and change out the threshold??

Thanks,
Joey

 

Use a small straight-shank punch the same size as the heads of the finish nails in the door trim, and sink them. (Do not use a nail set as this will enlarge the holes.)
Sinking the nails will cause far less damage than trying to pry the trim off.
Then all that you have to do to replace it is to drive new nails into the same small holes, countersink them, putty, prime and paint.
Good luck!
Mike
