Troubleshooting New Thule Key that Won't Turn Lock on Cargo Box
Updated 06/11/2025 | Published 06/24/2020 >
Question:
I went to open my Thule box after hanging up for a couple years and my locks won’t open. Not sure what to do. I did order a replacement key, which I wanted anyway, but I don’t think it’s a key issue.

Expert Reply:
Does the key turn at all? Or does it turn but not release the lock mechanism? It is not unusual to need to lightly tap the key all the way into place in the lock core the very first time you use it so that it seats fully. You can use a rubber mallet or small hammer to gently coax the key into its fully-inserted position. This usually does the trick.

Our key turns but the trigger doesn’t release the lock

I am having the same issue. I purchased a replacement key from you. Came in quicker than expected, too! Went to put the key in, perfect. Turned the lock, perfect. Box still won't open. The silver part of the lock sticks out almost an inch. IS it a Button?? are the insides of the locking mechanism not turning? I cannot figure it out.
