If it's the outside handle, simply go to your local autoparts store in the HELP section, they will have the black or chrome handles there...
Pull the door panel, make sure the window is all the way up, pop off the linkage at the door handle... Using a 11mm socket on an extention, remove the nuts on either side of the handle (be careful, the threads are plastic on the handle itself)... Remove... Reinstall the same way.. Very simple..
