About Central Locking

What is the central locking system/what does it do?

Central Locking systems are common or at least an option on most modern cars. It enables remote locking or unlocking of all doors from a key fob or from switches inside of the vehicle. This operation also functions with the insertion and turning of the key in the driver's and the front passenger door.

Getting into the details of the central locking system

On earlier makes and models that offered central locking the system was powered by a vacuum system. In general, modern makes and models are operated through the use of  small electric motors and gears in an actuator, one of which is positioned inside each door cavity below the door lock lever pull rod and adjacent to the rear door closure on the hatchback or estate. The central locking system can be part  of the security system controlled by the ECU (electronic control unit) which is part of the vehicle's computer system. Apart from controlling the central locking it may also control ignition lock, steering lock, alarm and immobilizer. Some ECUs also control automatic window closure, fuel flap locks and car vehicle tracking.

The system can consist of a separate control unit which picks up a radio signal pulse code from a preset key fob. Wired to the control unit are the actuators which run when the signal is received and push up the lock rod and open the lock. When the lock button on the fob is pressed the small electric motors run in the opposite direction and the actuator pulls the lock rod down. On some models the fob and control unit are programed and wired to control interior lights to switch on and remain on until the engine is started. Sometimes using the central locking can also activate or deactivate the alarm system.

The control of central locking is usually a two way switch on the center console or within the facia of the front doors, to open or close the locks on all the doors simultaneously . On some makes and models when locking the doors, any windows that are open will also close. There are also individual switches on each door that will operate that particular door.

What if something goes wrong with the central locking system?

Spares for the electric central locking system include actuators, control units, switches and key fobs. On older air vacuum systems they can include vacuum pumps and vacuum actuators.

MG trivia

  • Honda won the Manufacturer’s Championship for a four-year streak but was finally destroyed by MG in 2014 when the MG6 GT (which had only been competing for three years) beat its rival with an impressive 95-point win at Brands Hatch. MG also came second in the Constructors Championship in 2015.
  • Every year, the Chesterfield MG Group holds what’s called the Goodnight Sweetheart Run. It’s a chance for classic MG owners to have one last drive before the colder weather hits and their cars go into storage for the winter. Held every September, the Goodnight Sweetheart Run is a must-attend event for every MG owner.
  • Quite a few celebrities have owned an MG. The Duke of Edinburgh had a TC model, while Prince Charles’ first ever car was a GT SHY 766F, which he loved so much that he kept it until he could pass it to Prince William. The King of Rock and Roll, Elvis, also had an MG, as did Geri Halliwell and Sharon Stone.
  • In 1931 the MG EX210 became the first 750cc car to beat the 100mph mark and managed 103.13mph. Nicknamed the Magic Midget, the EX120 took a few attempts to break that record, but it got there eventually.
  • The best selling MG of all time is the MGB. Released in 1962 and in production until 1980, the MGB is still the epitome of the modern British sports car, and was, in fact, the last MG to be built at the world-famous factory in Abingdon.
