Sorry to report it was easily opened in about 20 seconds, on my third attempt. I had just sat on the couch, started to watch Carl Sagan's Cosmos on the Discovery Science Channel and click, it opened.
The keyway is soooo tiny, the wrench gets in the way of moving the pick in and out. I used a slimline medium hook.
I think I had more trouble with a proseries 6121, but I swear this is what's under that black rubber coating.. anyone confirm?
