a few years ago I went to Pigeon Forge with my daughter's softball team. On of the other Dad also rides, and since we had an "off" day on the schedule, we trailered our bikes up there so we could get some riding in. To make a long story short, it just so happened that I had to move the trailer which was secured to a utility pole using a cable lock. My friend was about a hundred miles away on his bike, and he had the key to the lock.
I went to the local hw store and bought a $4 hacksaw and ten minutes later the cable lock was history.
