With it, you’ll never again be in danger of losing one of the keys or forgetting the opening code and having to replace the padlock. Whether it’s for a cellar door shared with a bunch of neighbours, to use on a construction site, access to your locker in the office or a bike shed, the keyless ABUS Touch™ 57 is suitable for countless applications. Another security aspect: Thanks to the fingerprint scanner and its encrypted memory, unauthorised persons are prevented from spying on an opening code or stealing a key. With its shackle made of specially hardened steel, zinc body and double ball lock, it is thus one of the most secure fingerprint padlocks on the market today. The ABUS Touch™ 57 is made of high-quality material. You can rely on our security standards, our experience and our proven quality: ABUS has been the expert in padlocks for almost a century. Another advantage: The lock can also fall into water without moisture penetrating. It is protected against both the ingress of dust and foreign matter as well as heavy splashing water, such as from a garden hose or heavy rain. No rust, no penetration of dirt and water: Its IP 66 and IP 68 rating means that the ABUS Touch™ 57 can be used outdoors just as easily as indoors. It takes ten seconds to activate “delete” mode, so it’s almost impossible to accidentally delete fingerprints. As one of two administrators, simply place your own, already registered finger on the fingerprint sensor for three seconds and the "register" mode will be activated. It takes almost no time to register fingerprints. The 360°-capable sensor identifies up to 20 registered fingerprints from any position - no matter how they are placed. It requires neither key nor opening code.

Once all three indentations are aligned properly by this process, the lock opens. When you turn the dial clockwise again, only the top cam rotates. The friction provided by the spring, however, keeps the third cam in its position. As you go past the first number, the first cam's tooth engages the second cam, so now the two cams are moving. Now when you turn counter-clockwise only the top cam is rotating. Turning the dial 2 full revolutions gets the teeth of all three cams engaged, so the three cams are turning in unison. Then turn the dial clockwise to the third number and the lock will open." You can now see why you have to do that. Then turn it counter-clockwise past the first number to the second number. If you have used a combination lock before you know the drill: "Turn the dial clockwise two full rotations to the first number of the combination. Otherwise the latch engages the hasp like this: When the indentations align properly the latch is able to fit into the indentations and release the hasp: The cams each have an indentation in them. The purpose of the cams is to control a latch that engages the end of the lock's hasp.
The cams each have one tooth on each side, and these teeth engage as the cams rotate: The spring provides friction between the cams to hold them in place. They fit on a shaft molded into the back of the lock with a spring pressing the stack of cams together when the lock is assembled.
