On the door lock failure page we described the failure symptoms and the procedure for getting the door open. Once this is achieved, the next order of business is to remove the old latch from the door and replace it with a new one. Andrew Parker kindly supplied the information and photos herein describing the procedure.
#2 Stubby Phillips head screw driver,
Torx Bit with nut driver.
Wire cutter & stripper
Crimp connectors or soldering iron
Insulation tape or heat shrink tubing
You will need one of the following latch assemblies depending on which door latch has failed:
FQJ103240 right front door - left hand drive
FQJ103250 left front door - left hand drive
FQJ103220 right front door - right hand drive
FQJ103230 left front door - right hand drive
In the US, I found Atlantic British has the necessary OEM parts for LHD vehicles for $224.95.
Procedure for Removing the Old Latch
1. Put the window up and pull the tweeter housing from the doorframe. It is fixed with a spring clip in a slot with the bottom having a lip which registers into the trim panel so pry it from the top first and draw down until the clip is pulled from the doorframe. Unplug connector and set aside.
2. Remove the #2 Phillips-head screw from trim panel were the tweeter-housing covers it.
Using a cloth to protect
doors paint and
a large screw driver, pry interior trim panel around bottom and sides
careful not to yank the midrange speaker wire as it is mounted in the
not the door. Disconnect the connector
and lift the panel up and over the lock button and set the panel aside.
4. Remove all black and red plastic pins that fix the interior panel from the doorframe (see photo of removed pins below left). If any of the black connectors pull out of the panel repair with 5-Minute Epoxy now.
Remove insulation around
back half of the
doorframe and tape it open with some duct tape.
6. Unsnap green plastic keeper from exterior-door-handles-push rod on the door latch.
7. Unsnap interior door handle cable from door latch.
8. Remove three Torx headed screws that fix latch to door.

9. With latch free twist it inside the doorframe so as to allow push button lock rod to be disconnected from latch.
10. Remove latch keeping attention to wire and connector routing inside the door.
