Unless of course you have access to a common Bic pen.

You take the pen "body" and strip everything out of it front and rear,
leaving a thick plastic "straw" the same diameter as the ring key hole.
You then jam the end of the "straw" in the hole. The plastic is soft
enough that the tumblers that won't depress will jam into the plastic,
yet the plastic is hard enough to otherwise operate the lock.

Bike thieves figured this out on Kryptonite locks that use this
mechanism but ALL circular-end "ring keys" of this standard diameter are
vulnerable.

A *good* quality conventional lock is best...most, as used in cash
registers and the like, are crud.
