Question:

i purchased a GM Roof Top Box for a 2001 GMC Yukon XL Surburban and although I sold the Vehicle I kept the Box, but it remains locked. Does any N126 unlock this Box? The aforementioned # appears on the lock cylinders on each side of the Roof Top Box

The NXXX keys are unique to Thule-made cargo boxes. It does appear that Thule has made cargo boxes for GM so replacement key # THKEYN126 is the correct replacement.

One tip I can offer is that sometimes the new keys won't fully seat all the way in the older locks. If this happens you can tap on the key with a mallet to get it to seat all the way so that it will turn.
