Expert Reply:
There are replacement lock cylinders and keys available for your Thule Mountaineer as well as hinges.
For lock cylinders you want the Thule One-Key System Lock Cylinders # TH450200 while for the hinges the correct replacements are the Replacement Dual Force Strut for Thule Roof Box # TH14933.
I have added links to video reviews of these parts for you to take a look at as well.

The locks will fit but they will not allow the inner mechanism for unlocking to work as back of cylinder does not have provision for attaching the necessary screw. You have to drill and tap the hole.
