A power door lock is a kind of lock available in many kinds of motor vehicles that allows the driver of the vehicle to control the locks on all of the vehicle doors and, in some cases, the lock on the trunk of the vehicle. In addition to being referred to as a power door lock, this kind of lock is also referred to as an electric door lock. Sometimes the system of being able to control all of the locks within a car is referred to as a central locking system. The control panel that allows the driver to control all of the locks within the car is usually located on the inside of the door on the driver's side of the car.
There are a number of reasons why one might choose a vehicle with a power door lock. Many of these have to do with the safety of the driver, as well as the safety of the passengers within the car. A family with young children may choose a station wagon with a power door lock so they can make sure that the doors in the back of the car where the children sit are locked even if the doors in the front where the adults sit are not. A power door lock system can also protect a person who is traveling on his own, as it can allow him to secure all of the doors of the vehicle at one time.
In addition to controlling the doors and trunk of a vehicle, a power door lock system might also control the fuel cap on the car. Just as with the door and trunk locks, the driver of the car can release to cover on the fuel cap by simply activating a switch or button. These controls are usually in the same general area and may be located near controls that allow the driver to adjust the windows throughout the vehicle.
It is quite common for a power door lock system to be available in newly fabricated vehicle models. There is also a powder door lock feature that locks all of the doors once the car reaches a certain speed. This power door lock feature is also commonly used to secure cars in which children regularly ride. Another power door lock feature allows drivers to unlock the doors of their cars by pressing certain keychain buttons.
