A Kryptonite spokesperson offered these details: "Kryptonite has put in place a Lock Exchange Program. This is _not_ a recall. Anyone with a Kryptonite lock that has a tubular cylinder can sign up to have that lock exchanged for a non-tubular cylinder lock. It is very easy for consumers. They go to our web site [see link below], fill out a form with their name, address and lock type, and they will get an email back shortly with a UPS call tag (postage paid). They send back the lock to us, at our cost, and a new one will be sent to them free. This is any Kryptonite lock, or any lock made by Kryptonite (including our co-branded products), no matter how old the lock is and no proof of purchase is necessary. The only things people need are the lock and keys."
