We have not had any complaints regarding the Self-Locking, Aluminum Ball Mount, # DTALBM6625, locking up or freezing. Sometimes you may need to lift up on or jostle the ball mount to take pressure off of it so it is easier to turn the key.
Diversi-Tech recommends using air tool oil in the locking mechanisms to keep it in good working condition. You can check out the customer reviews on the product page. I have also included a link to a video review for you.
