If you lose your key or another valuable item, you often don't know where to look to find it again. What often fails is not because of honest finders, but rather because of the ability to locate the owner. In the event of a loss, the honest finder can report the find via CODE-No.com. With the back-to-me key ring and the service of CODE-No. this challenge will be remedied. Simply attach the trailer, register for free at www.CODE-NO.com/ABUS and activate your personal CODE number. Or even faster: scan the QR code on the back. An international (anonymous) return of the item will then be arranged.
