Remove the lock cover by undoing the 4 x M6 Bolts on the lock cover.

(you may need to support the lock cover as the final bolts are undone, if this has an internal LED light, this will be connected to the lock cover)

Once the lock cover is off, unclip the locking rods from the latch assembly.

Unplug the central locking (if applicable)

Undo the 2 M6 nuts and 2 x M5 bolts supporting the handle assembly.

This is glued on also so will retain itself in place. 

Prize off the handle assembly. You may need to use a flat head screwdriver to help lever this off. 

Once the handle is removed, apply a bead of adhesive sealer around the handle.

Place the handle onto the door and secure onto the studs also ensuring that the M5 bolts in the bottom of the handle line up also.

NOTE: Do not overtighten the M6 nyloc nuts, these are to help hold the handle in place while the glue dries.

Secure the base of the handle using the countersink M5 bolts

Reconnect the actuator if applicable. 

Re-install the locking rods.

Test that the latch works correctly. 

Re-install the lock cover using the 4 x M6 Bolts removed earlier.
