Door lock cable

A door lock cable is a critical mechanical component in modern automotive and architectural locking systems. It transmits manual or electronic force from the handle or actuator to the latch mechanism, ensuring secure closure and release. In vehicles, these cables connect the interior door handle, exterior handle, and central locking actuator to the latch assembly. The cable typically consists of a flexible inner wire (often galvanized steel or stainless steel) encased in a durable plastic or rubber sheath to reduce friction and prevent corrosion. Door lock cables are designed for high cycle life, often exceeding 100,000 operations, and must withstand temperature extremes from -40°C to 80°C. They are used in passenger cars, trucks, buses, and heavy equipment, as well as in residential and commercial door systems. The global market for door lock cables is driven by automotive production volumes, vehicle electrification trends, and increasing demand for keyless entry systems.
