Once I tried the TiKeY I knew for sure it was a keeper so I just had new keys made for a couple bucks and then experimented with different washer and key configurations. Finally I decided a washer between each key was best and tightened it until the keys would come out easy but not too loose or tight. Once I had it the way I was happy with it I used a little blue lock tight
(Not Red!) which keeps it just the way I like it and I can still change it in the future if I want too. Had one for close to a year now with about 8 keys on it and It's still as good as new!
