Your so going to kick yourself when you see how easy this is. mitch_lx its almost as simple as changing the gear knob hehe.
1. Remove this screw.
2. Pull the door handle out abit. Then remove the cover over the lock like the 2 pics below.
3. Now just pull the handle like your opening the door. It should just pull out
Now to reinsert the handle its alittle different.
1. Look into the hole where the handle goes you should see a rod and screw. Push this down. On the drivers side it locks down but on the passenger side it doesn't so you need to hold it down on the left side of the hole with your finger or screw driver. So when you insert the handle its not in the way. If you don't push this down the handle will not unlock or lock the door.
Once pushed down it should look like this
2. Insert the handle with the front section first. Then replace the cover over the lock and replace the screw. Lastly just pull the handle once to free the rod you pushed down and the door should now unlock and lock perfectly.
