Replacing Trunk Locks
What you need:
Time: 15 minutes
First, insert the shaft into the lock. The little metal hook should go through on the springs and come out on the little whole at the bottom.
Insert the gasket around the lock as it shown below.
Now insert the lock to it’s position from the outside while you are leading the shaft through the little hole in the middle.
Finally, push the retainer from the side in the following way to fix the lock in place.
Voila! You have a new lock mechanism in place. Regardless how incredible simple the whole mechanism is, it should hold pretty stable. Give it a few try with your key and try to wiggle the shaft a little to make sure everything is solid. If the shaft is too long, use a tool to cut it into size.
