You take off the interior door panel
Remove the 3 screws holding the outside door handle
TIP: Disconnect the outside handle rod from the lock assembly before removing the handle.
Probably you'll have to have the new handle painted to match unless you're lucky and can score a used one of the same color from a wrecker,
ask the dealer if they come painted--I kinda doubt it.
You can also buy them on Amazon, but I have no idea of the quality.
