Begin by removing the lock cover from the door.

You only need to remove the M6 bolt and x1 nyloc that hold the latch and cover to the door.

Remove the latch components from the latch and place in a vice. 

Bend the latch prong outwards.

Originally the prong will be at a 90 degree angle, now it should sit at approximately 100 degrees.

Fasten the latch components back on to the latch. 

Ensure that the prong hits the locking mechanism to make sure you have adjusted the angle enough.

Place the lock cover back on. 

Fasten the lock cover back over the latch and complete the same process on the other rear door latch.
