Locking tuner problem

I just became the proud owner of a Luke III buttermilk. I bought it 1/31 haven’t put it down since. Well I decided to change the strings to 10s wish is what I have on all my strats with locking tuners. First thing I noticed was all the locking wheels were extremely tight, when I got to the high E it was a challenge. When it finally broke loose it did not want to let go of the string, when it finally did, the new string was a bit hard to get through. I locked it but as I try to tune it would brake loose, every attempt to lock would make the tuner post spin too. Now the tuner is very hard to turn and it just broke the new string. I submitted a repair order with Sweetwater let’s see what happens. It’s just a bit discouraging to finally get my hand on a Luke and couple of days in this happens.
