My bike lock (A standard O-ring wheel lock) is extremely broken. I tried to open it like I normally would, but it didn't open, it tried forcing the key a little harder, and now the key is broken and stuck in there.
Now, with even more aggression, the cylinder in which the key goes, can spin around full circle but it still won't open. Any suggestions other than a saw? I only have a tiny hacksaw and it is going to take ages.
