Door & Lock Motors, Switches, Relays

Used to adorn only luxury vehicles, accessories like power door locks are standard equipment on most new vehicles, and having to push and pull door lock buttons is only a memory for most drivers. These handy amenities dial up maximum levels of convenience, opening the doors automatically. The door lock switches are usually mounted on the doors for easy access, enabling the driver and passengers to lock and unlock the doors with just the touch of a button. And with this feature, the door locks in the entire vehicle can be controlled from the comfort of the driver’s seat.

Power door locks use either solenoids or reversible electric motors to operate the locking mechanisms. Like power windows, each door will have a switch, with a master switch for all doors located on the driver’s door. Depending on the configuration, a relay may or may not be included in the control system. The rear doors on most cars have built-in child safety locks that, when activated, prevent the rear doors from being opened from the inside of the vehicle. This helps make traveling with kids safer, keeping those precious little passengers from accidentally, or intentionally opening the door while on the move.

Many vehicles with power door locks also have a keyless entry system. There are keypad systems and remote systems that enable the doors to be locked and unlocked remotely by pressing a button on a key fob. The keypad system has a numeric coded button keypad on the driver’s door and a control module. When the proper code is entered, the driver’s door will unlock. The other doors can be unlocked by pressing a certain button on the keypad within a set time period after the code is entered. This helps prevent unrestricted entry and vehicle theft. Remote systems include a receiver located inside the vehicle and a transmitter in the key fob that enables the locks to be actuated from a distance of 25 to 50 ft. from the vehicle.

Automatic door locks are another feature found on newer vehicles that takes advantage of the existing power door locks to provide additional safety for vehicle occupants. These systems generally lock the doors when the shift lever is placed in Drive or the vehicle is moving at 15 mph or faster, and unlock the doors when the lever is returned to Park. The body control computer or a separate door lock module controls the door lock relays and decides when to do the unlocking. Extra protection provided by automatically locked doors allows you to keep your eyes on the road and your hands on the steering wheel, knowing that everyone stays where they belong during your road adventures – inside your vehicle.
