If you can't find your lock on the Sold Secure website, please try searching for the specific lock model rather than the manufacturer. For example, if searching for a 'Kyroptonite Evolution Mini 7' lock, 'Kryptonite' will not yield any results but 'Evolution' will.
If you are still not successful in finding your lock, please contact Sold Secure directly, or you can check the packaging of the lock, as this often has the rating specified.
