Question:

I have a Thule Weekender and am looking for the complete lock assembly not just the cylinder key lock. The plastic piece the holds the cylinder is broken. Thanks

Hi Carl; I'm sorry to say the plastic piece/lock housing for the Thule Weekender isn't an available replacement part. It isn't even listed on the old parts list in the Thule archives. You can try to get creative and rig up a different lock like the # SR03807 to work but it might be more trouble than it's worth. Outside of that the only thing you can do is replace it with a new roof box like the Benton ShellRaiser # B44FR.

Hey Carl, did you decide to try a different lock or go with a new roof box like the Benton ShellRaiser? I'm curious to know how it worked out for you, as it could help others facing a similar issue.
