Jelaskan Special types of keys dari Sosi dalam bahasa sunda

A house key is the most common kind of key. When held upright as if to open a door, a series of grooves on either side of the key limits the type of lock cylinder the key can slide into. As the key slides into the lock, a series of notches allow the pins to move up and down until those pins are in line with the shéar line of the cylinder, allowing that cylinder to rotate freely inside the lock and the lock to open.
