Q

I can't see the keys very well. What kind are they? In other words, how simple are they to pick - bypass, etc.

A
  • I'm not sure what you mean by what kind of keys are they? I'm very satisfied with this purchase. I think the pitch of the alarm itself would give a would-be-thief a heart attack from fright.

    This would be perfect for something outdoors. I purchased it for a refrigerator lock, and was amazed at how big this was, which is why I only gave it 4 stars. This would fit a bike lock or storage lock because the shackle is huge. The photo doesn't really show how large it is. If my bike hadn't already been stolen this would have been a perfect lock. It will sound an alarm, that will draw people's attention and scare any would be thief.

    I bought two of these. They work pretty well. I attach one to a Motorcycle and another to a bicycle. I am sure they are defeatable but they would still give a thief pause. Pretty darn loud too. I never read the instructions, just read the comments here and found that you can set it to be on or off by turning the shank 180 degrees.
