theyre called skikeys, and theyre disabled by a common screwdriver
I believe that a screw driver could break the lock but you would also need a hammer to tap (3 taps?) the screw driver in. So if I'm in the lodge and see someone swinging a hammer near my board, I'll bust a chair over their head.
Where as the Ball and Chain can be cut with Bolt cutters. Bolt cutters although cumbersome, can be hidden under a jacket. So theft would be much more discrete.
Those retractable coil locks are trash and can be cut with tin shears. But they are a mild deterrent.
In the end, most thieves will avoid locks and just take the unlocked board. The exception being, the thief wants your board, considers your lock not a problem and the board is worth the risk of getting caught.
PS - So I guess the best answer is to find the old style locking snowboard racks and pay the $1 in quarters to lock your board up.
