Been over a month since I’ve received a response regarding my stolen bike!

Hello - apologies for the delay. I've requested additional information so that a member of our team can follow up with you regarding your claim.
I requested a replacement key on 10th September, ref #433615, and was told I would have to wait 2-3 months. It's been over 3 months now and no response. I have been unable to use my bike this entire time and have spent a lot of money on alternative transport. Shocked at the length of time this is taking and very frustrated with a complete lack of communication from this company. Judging by the other reviews this is a common experience.

Over 2 weeks waiting for a warranty claim response that I made through the website and nothing. I'm forced to order a new one as I need it for my commute and can't really use my bike without a lock. Now have been waiting for longer than a week for it to be delivered. These guys suck.

I bought the Kryptonite Avenue F-150 and Avenue R-75 COB Light Combo, which broke after only 3 months. I therefore asked customer service for a replacement. Initially I received a reply (every 1-1.5 weeks) and from the beginning of October no reply at all. I have made 2 more tickets, but so far no reply.

Hello - I apologize for any inconvenience. I have requested additional information from you so that I can have someone follow up with you right away.
Edit: Nachdem ich meine Bewertung abgegeben habe, hat der Kundendienst prompt reagiert. Mittlerweile habe ich die Ersatzschlüssel erhalten und auch der Zahlungsbetrag wurde mir zurückerstattet. Danke an dieser Stelle dafür. Eine solche Reaktion habe ich nicht erwartet. Originalbewertung: Habe im Februar ein Kryptolock 912 erstanden, bei dem mittlerweile beide Schlüssel ihre Funktion eingestellt haben. Das alleine ist schon Grund für eine Abwertung. Die Ersatzschlüssel habe ich vor 6 Wochen bestellt. Bislang ist aber noch kein Ersatz eingetroffen. Der Kundenservice ist praktisch nicht vorhanden. Eine Anfrage landet im elektronischen Nirvana von Zendesk. Insgesamt habe ich 100 EUR in den Sand gesetzt. Aus meiner Sicht ein klares Veto gegen zukünftige Käufe dieses Anbieters.

Wir entschuldigen uns für die Verzögerungen und Unannehmlichkeiten. Ein Mitglied unseres Teams sollte sich bald bezüglich Ihrer Schlüsselbestellung an Sie wenden. Vielen Dank für Ihre Geduld.
Quick resolution to my problem after my negative Trustpilot review. I ordered replacement keys, which arrived promptly but did not fit. On contacting customer service I received no reply, but after my review here I was refunded for the useless keys and as a courtesy received a new lock. Great service in the end, just a shame it couldn't be achieved without a public complaint.

Purchased a lock just under a year ago, key stuck in the lock and not able to extract. Local locksmith told me it wasn't fixable. Tried to contact customer service (as comfortably within warranty period) with all the details specified in the contact form, but have had ZERO response for 26 days, despite commenting on the zendesk ticket. Phoned them to follow up on the issue, simply told "someone will get back to you at some point". Tried phoning again and stuck on permanent hold Nothing I can do at this point but purchase a new lock. Plenty of other companies selling locks - suggest you take your business elsewhere.
