The key number is needed to order new keys. There is nothing on the lock referring to the keys. If you have registered please submit a request to look up your registration.
If you did not register, unfortunately without the key number from the keys there is no way for us to mail you a new key. For security purposes the number is only stamped on the key itself. Anything on the lock, packaging or insert is generic information.
For US/CANADA customers, if you have lost your keys/combination and did not register please click this link to get more information on having your lock replaced through our Lock Out Replacement service: Lock Out Replacement
