I'm trying to finally get my WOZ 100% and was hoping someone with a 100% working lock mech could help me trouble shoot mine. My will release two balls about 25% of the time which sucks IMO. I've read about bending the arm. I also would be interested hearing from someone with a newer WOZ, mine is July 2013, to find out if there are factory changes to make the lock function properly.
Thanks.
