Assuming you need to replace the handle on the driver’s side door: 1. Open the door and unscrew the screws that hold the armrest in place. There should be three screws in total. Keep track of which screws go where, as they will be different sizes. 2. Once the armrest is off, there will be a plastic cover over the inside door handle. Pry this off with a flathead screwdriver or trim panel tool. 3. Now you will see the Phillips head screws that hold the door handle in place. Unscrew these and remove the old door handle. 4. Take your new door handle and line it up with the holes left by the old one. Screw it into place using the same size screws as before (make sure to put them back in their original locations). 5a. If your new door handle came with a plastic cover like your old one did, snap this into place now coversing any exposed screwheads . OR 5b If it did not come with a new cover, reuse your old one by snapping it back into its original location.. 6. Put your armrest back on by lining up the holes and screwing it into place using those three different sized screws from earlier
