Troubleshooting Thule Cargo Box Key Turning But Not Engaging Lock On Box

Question:

I just picked up a used Thule cargo box and it didnt have keys. so I ordered new keys, The keys work on one side but not the other. The keys turns in the lock but wont engage the 3 locking pins on the inside it just stays unlocked. I sprayed them with 3n1 lock oil. It helped with the key sticking but thats it

It sounds like you may either need a new lock core or the latch needs to be changed out. We do have the Thule One-Key System # TH450200 which contains 2 new lock cores for both sides of your cargo box with matching keys. A Change Key # 853-1251 can be used to move your current lock core from one side to the other to determine if the issue is with the core or with the latch itself. If you can tell me what cargo box you have I can verify if a replacement latch is available.
