I work for a Nissan dealer and had this problem that some Titan/Frontier/Xterra will work on one pad lock. We got the 2 pads locks for a Frontier and tried other Nissan locks to see if it would work and 4 out 6 keys did work. Called up the company to tell them what was going on, they said that they had a bad batch of tumblers and the lock only has 7 preset cut tumblers that Nissan have and some other Nissan keys can open it. (Sad)Am I correct in assuming, though, that anyone with a Nissan key could open it?
They do have them. We got ours from a company called Midstates Distributors in Colorado. they are a wholesale company so you might have to order large amount.
Just found it as a receiver lock - https://www.amazon.com/BOLT-7023583..._SR160,160_&psc=1&refRID=NC87AVYAJ0RVJE12QHTX
