Things That Drive Me Crazy

I ordered a roof rack system from Amazon thst clamps onto the Hyundai's roof bars intended for that purpose.  The left and right attachment mechanisms of course have locks to prevent theft.  The key fits three of the four locks. It will not even insert into the fourth. The logical step would be replace one appropriately keyed, or even all four. No. All Amazon can do is send me a new unit.  Keep the bad one. I may try and figure out to repair that bad lock.

It is hard to believe this is cost effective.
