Plug it up in your car, then select Custom Tune. It will tell you if it can run the tune on your car or not. If it can't, hand it back and go get a new one.
I use my XCal to check DTCs on my wife's van all the time, and I've never seen a message on the first screen telling me that it was unlocked. Mine is an XCal2 though.
