There are two basic types of padlock locking mechanisms: integrated & modular. Integrated locking mechanisms directly engage the padlock's shackle with the tumblers. Padlocks with integrated locking mechanisms are characterized by a design that does not allow disassembly of the padlock. The more modern modular locking mechanisms, however, do not directly employ the tumblers to lock the shackle. Instead, they have a plug within the "cylinder" that, with the correct key, turns and allows a mechanism, referred to as a "locking dog"to retract from notches cut into the shackle. Padlocks with modular locking mechanisms can often be taken apart to change the tumblers or to service the lock. Modular locking mechanism cylinders frequently employ pin, wafer, and disk tumblers.
