Power door locks (also known as electric door locks or central locking) allow the driver or front passenger to simultaneously lock or unlock all the doors of an automobile or truck, by pressing a button or flipping a switch.
Power door locks were introduced on the luxury Scripps-Booth in 1914, but were not common on luxury cars until Packard reintroduced them in 1956. Nearly every car model today offers this feature as at least optional equipment.
Early systems locked and unlocked only the car doors. Many cars today also feature systems which can unlock such things as the luggage compartment or fuel filler cap door. It is also common on modern cars for the locks to activate automatically when the car is put into gear or reaches a certain speed.

Famous quotes containing the words power, door and/or locks:
“The preservation of life seems to be rather a slogan than a genuine goal of the anti-abortion forces; what they want is control. Control over behavior: power over women. Women in the anti-choice movement want to share in male power over women, and do so by denying their own womanhood, their own rights and responsibilities.”
—Ursula K. Le Guin (b. 1929)
“There is the empty chapel, only the wind’s home.
It has no windows, and the door swings,
Dry bones can harm no one.”
—T.S. (Thomas Stearns)
“Nodding, its great head rattling like a gourd,
And locks like seaweed strung on the stinking stone,
The nightmare stumbles past,”
—Robert Penn Warren (1905–1989)
