Finally it's time to replace my original smart key which has been patented after 10 years. I applied titanium to keep the paint from peeling. The design works really well, keeping your keys organized and not letting them rattle. I think rubber lock washers should be replaced with lock washers or lock nuts and stainless steel hardware should be replaced with anodized steel or titanium. The big problem with a key store is when it falls apart in your pocket and you fix it on the go as you might and it falls apart again resulting in you losing your pucks or worse your keys.
