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.
- Most people think of silver when they think of a Mercedes, but that iconic colour was an accident. Just before a race in 1934, the white-painted W25 was found to be 1kg over the weight limit. The paint was quickly removed, the weight limit reached, and the car won the race.
- Unlike most cars, Mercedes vehicles are not spray painted. Instead, they are completely submerged in anti-corrosion coating and primer. That means the protective liquid can get into every part of the car.
- If you thought self-driving cars were all about Tesla, then it might surprise you to know that Mercedes Benz made an autonomously driving vehicle as early as 1995. It didn't gain popularity, but it became the foundation of the modern driving technology found in every Mercedes Benz.
- Mercedes Benz cars have always been a big part of the Jurassic Park films, but the first movie went all out, with the stars emerging from a red Mercedes GLE Coupe before walking down the red carpet. Mercedes cars are also used throughout the film franchise.
- Karl Benz obviously gave his name to the company, but the Mercedes part of the name comes from the daughter of his customer and friend, Emil Jellinek. Her name was (obviously) Mercedes, and it's still surprising that her name remains so attached to the iconic car brand.
