Warranty claims can be started at the Bitkey warranty center. You will need your Bitkey order number and the email address you used when you placed your order. All requests will be reviewed and processed within 72 hours. Once your request has been approved, you will receive an email with additional instructions including how to place an order for a replacement device and a link to the return shipping label. See What do I need to do to return my device for a warranty claim? for more information.
