I am fortunate that I can bring my bikes inside but I recently had to run some errands, so I pulled out this old Trek by Kryptonite Ulock I've had forever. As soon as I looked at it I remembered the whole bic pen thing (I also quickly pulled out a moto Kryptonite disc lock I bought a while ago). Of course I have missed the voluntary replacement and they are not on the settlement page and I can not unlock with a BIC, but I do not want to chance it, plus I already picked up a OnGuard Pitbull at a great price, which is adequate for the moto and cycles.

I guess i have two questions:
Anybody know of a way to verify which ones? I called and they said any tubular lock from them is possible.
Assuming they are bad should I just chuck them in the garbage? Seems like a waste there has to be some good use for them?
