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:
“By my soul I swear
There is no power in the tongue of man
To alter me.”
—William Shakespeare (1564–1616)
“It is remarkable how easily and insensibly we fall into a particular route, and make a beaten track for ourselves. I had not lived there a week before my feet wore a path from my door to the pond-side; and though it is five or six years since I trod it, it is still quite distinct. It is true, I fear, that others may have fallen into it, and so helped to keep it open.”
—Henry David Thoreau (1817–1862)
“If courtesans and strumpets were to be prosecuted with as much rigour as some silly people would have it, what locks or bars would be sufficient to preserve the honour of our wives and daughters?”
—Bernard Mandeville (1670–1733)
