Question:

I only have one key for my Thule Rod Vault, and I want to obtain some spare keys. The code on the key is B31121.

Hey Jack, thanks for the information. I've got keys for the A31121 - Qty 2 item # TH46WH and a C31121 - Qty 2 item # TH69VK lock cores but nothing with a B31121. Additionally, I checked with Thule and they did not have a key with your B31121 key code on it either.

Are there any numbers stamped into the lock core itself?

Hey Jack, did you have a chance to check if there are any numbers stamped into the lock core itself? If you’re still looking for a solution, I’m happy to help.
