Handles & Locks, found within the Body > Internal Body Parts section, are critical components for vehicle access, security, and interior functionality. These parts control operation of doors, hoods, trunks, glove compartments, and seating adjustments. Handles provide the mechanical interface for opening and closing these access points, while locks secure them against unauthorized entry or accidental movement. Materials commonly include durable plastics, steel, and zinc alloys for longevity and resistance to wear. Examples within this category include interior door handles like the Febi MPN FEBI23402 for Audi and BMW vehicles, as well as exterior door handles and locking mechanisms suitable for Volkswagen and other passenger cars and commercial vehicles - like the Febi MPN FEBI15676. Proper function of these parts ensures both passenger safety and vehicle security.
