I will wait for my husband to come home to do this as I have somewhat arthritic hands. I will hold off on the rating until then if that is all right with you. I dont like rating someone until I have given a good attempt at trying to solve my problem. I will be in touch this afternoon.
We fixed it but not unscrewing anything. We used a pair of pliers and eased the lock back. Easy for a man with strong hands but a woman fast approaching 70....well, I am not as strong with my hands as I used to be...sadly that is life. Anyway it is fixed.
