Power locks have been improving vehicle safety and convenience for more than a century. Introduced in 1914, they allow drivers to secure all doors at once with the press of a button—either from a switch inside the vehicle or through a remote key fob. This central locking system makes it easy to manage access when multiple passengers are entering or exiting and provides added safety by quickly securing the vehicle when needed.

Today, power door locks are standard on most vehicles, integrated with modern security and keyless entry systems that make everyday driving more secure and convenient.
