  1. Hurt, no treatment

    Made Jun 16, 2015, sent to the company Jun 24, 2015, published by CPSC Jul 9, 2015

    The product, in the report: A bicycle lock shaped like a pair of handcuffs.

    Both my wife and I have received numerous injuries from using Master Lock Street Cuffs bicycle locks. Most of the time the injuries are small cuts similar to paper cuts. However, both of us have gotten more serious cuts where the bleeding was difficult to stop.

    Because of the danger of infection from a bike lock’s dirty environment, we have both looked for the cause of these cuts and finally determined that the chrome plating was flaking off of the locks. The plating loosens and flakes may stand up like little scalpels. From time to time a flake slices the skin when the lock is handled.

    I contacted Master Lock and they offered a refund and replacement locks. Since my concern was all the users of these locks, I refused the refund, but I did accept replacement locks. The replacements exhibit the same problem. Master Lock has some of the failed locks, as well as photos documenting the problem.

    After Master Lock confirmed that they had received the faulty locks, they stopped communicating with me. Finally after about six weeks, I received email that said, “have not found any additional examples of the specific failure mode you described”, even though my replacement locks have failed in the same way. In addition Master Lock cautioned that, “Any future emails or correspondence being sent directly to <name withheld> will not be responded to.” And finally, “Master Lock now considers this complaint to be closed.”

    My concern was never for any personal compensation for our injuries, but rather for the safety of other people using these locks. Thus, this complaint.
