I have the Moab's and used the stock lug nutz also. I did have the McGard lock nutz until the tire shop used an impact gun on them and broke one. That caused a big problem getting another one with the same pattern...blah..blah...blah...
From my experience I suggest:
1) Don't bother with the locks....( I live in Los Angeles and nobodys stolen my wheels in 3 years).
2) If you have to use the locks....dont give them to the tire shop, let them use 5 regular nutz and YOU put the locks on yourself and take them off prior to having anyone work on your Jeep. Remember that If you forget the "KEY" and your offroad...your outta luck in a big way.
Good luck
