They replaced a lock that had no longer worked. The overall warranty process was straightforward and they honored their lifetime warranty for this type of defect.

When I had an issue with my lock, I completed an online form and received a quick response. They’re sending me a replacement, honouring their lifetime warranty. No quibbles. I’m really impressed.

Placed an order for replacement keys on Aug 30. Received email acknowledgment promptly, but I am still waiting for keys, or a call back from customer service. I have left three messages since but no contact with a human.

After three years of exposure to Scandinavian weather, the lock stopped working. However, Kryptonite shipped a replacement under their lifetime warranty! I can’t believe it happened since I thought lifetime warranties were just a marketing gimmick. I highly recommend them and hope they continue to provide good products and customer service.

Ich habe mir das Kryptonite NY Diamond nach mehreren YouTube‑Videos gekauft. Das Schloss selbst macht einen sehr robusten Eindruck; auch die Beschichtung am Bügelende und an der Querstrebe wirkt hochwertig. Was jedoch ein absoluter Witz ist: Der mitgelieferte Schlosshalter ist für ein 2‑kg‑Schloss völlig ungeeignet. Für ein so teures Schloss einen billigen Halter beizulegen, der mit einem Band und etwas Gummi befestigt werden soll, ist enttäuschend. Das Band franst bereits aus, und an nicht runden Rahmen lässt sich der Halter kaum sinnvoll montieren. Aus diesem Grund vergebe ich nur 3 von 5 Sternen und werde mich nach einer alternativen Halterung umsehen.

Es tut mir leid zu hören, dass Sie Schwierigkeiten haben, Ihr Schloss am Fahrrad zu befestigen. Ich habe weitere Informationen angefordert, damit ein Mitglied unseres Teams Ihnen weiterhelfen kann.
