No, I am not keen to steal a bike, just get the cable lock off a bike that's hanging in my garage... the lock is a thick Schwinn cable lock, no ID #. It takes a key and the key was long ago lost by my kids (or me... if I knew it wouldn't be lost!).

I can ride the bike with the cable still coiled-onto the top tube, but it would be nice to dump that pointless extra weight.

Lock looks like this one: http://www.amazon.com/Schwinn-Cable-.../dp/B0018CPG3U yeah the keys looked just like those
