Using the ULAC X3 Monoblade folding lock is a breeze. First, use the velcro - style bracket to attach the lock to your bike. When you need to lock your bike, just unfold the lock and use the automatic push - to - lock cylinder design to secure it. Unlock it with the high - security Abloy key. For carrying, you can use the transportation bracket system. As for maintenance, keep the anti - dust lid on to protect the cylinder from dust and debris. Try to avoid exposing the lock to extreme temperatures and moisture. If the lock seems a bit stiff, you can use a small amount of graphite powder to lubricate it. Always make sure the key is inserted correctly to prevent any damage to the lock mechanism.
