WOOHOO!!!! I just got off the phone with Fastec. The toy hauler has two keys for the rear tailgate and 2 side doors. One of the side doors has a Global lock in it and the other has a Fastec lock in it.
For $4 bucks, they'll send me a replacement set of (2) cylinders and for $26 bucks, they'll send me a whole lock/handle assy to swap out of the rear side door.
For less than 40 bucks, I'll have all 6 locks keyed alike.
