Whoever tried to steal my commuter bike from outside Union Station in DC over the weekend left the stub end of a Bic pen jammed in the lock, so the bike is going to sit there until I figure out how to get the lock open. The lock cylinder turned about 15 degrees before the pen broke off, so it may be impossible to unlock the lock no matter what I do.
Assuming that the lock might still allow use of the key (since the plastic is presumably holding the pins and tumblers in place, maybe I can grab the solid inner cylinder in the keyway with a vicegrip), is there a solvent that would dissolve the plastic pen barrel thoroughly enough to allow the key to be used?
Otherwise, I suppose I could rent a cordless angle grinder.
Any other suggestions?
