I'm a little late to your reply. I agree with you in general that locks aren't the be-all/end-all in security. But, I don't feel your statement is completely correct. I can think of two reasons to have a good lock. 1. Not all insurance will cover theft unless there's evidence of a break-in. [1] This was a problem with the bump keys where no evidence of a break in was left, other than maybe some scratches on the face of the lock itself. 2. Padlocks, often including bike locks, can often be shimmed or raked easily. It's one thing to carry around a pair of large bolt cutters in downtown manhattan, it's another to carry a little shim in your pocket.

Insurance companies may still be resistant in paying on a claim, even with a forensic locksmiths findings."
