I have a thule xsporter rack I lost the keys to the locks on the bottom of rack. Is there a universal key or can I purchase a replacement key? The number on the locks are worn off.

Hey Patrick, thanks for reaching out!
Without the number on the lock core, you're looking at either having the core drilled out, or you'll have to find a Thule dealer that would be willing to try every single key they have until something works.
If you have the core drilled out you'll then need to replace it. To replace the lock on your Xsporter you'll need the Thule One-Key System Lock Cylinders # TH450200.
We also have the T-Slide Casting # 8523164001 and Clamp Lock Housing # 8523163001 if either of those end up getting damaged when the core is drilled.
What do you plan on doing?
