Using the Abus Booster 6512K Key Lock is a breeze. First, find a sturdy fixed object like a bike rack. Stretch out the 12 - mm thick cable to the needed length (it can go up to 180 cm) and loop it around your bike and the fixed object. Then, insert the key into the lock and turn it to secure the lock. When you're done, use the Snap Cage mount to carry the lock around easily. As for maintenance, keep the lock clean by wiping it with a dry cloth regularly. Avoid exposing it to extreme weather conditions for long periods. Also, make sure to keep the key in a safe place. If you notice any issues with the locking mechanism, don't try to fix it yourself. Instead, contact the Abus customer service.
