Scrod, so I picked up my fathers Cannondale mountain bike, and it's in pretty bomb condition. Decided to not fix what's not broken. Only problem is (other than reflectors galore) the bike comes with OnGuard locking skewers on the rear and front wheels and the seat post clamp. And of course, there's no KEY! What do you think I should do? Do you think some pliers would be able to get it off? Pretty sure this is it: http://www.amazon.com/OnGuard-3-Piec.../dp/B000C14NEG
