All You Need To Know About Car Central Locking System + FAQ's

Introduction:

Car central locking systems have become an essential and ubiquitous feature in today's automobiles, providing convenience, safety, and security to vehicle owners. In this comprehensive guide, we'll explore the purpose and benefits of a central locking system, how it works, its key components, and common reasons why it may not function correctly.

1. The Purpose and Benefits of a Vehicle Central Locking System

The central locking system serves the primary purpose of locking or unlocking all the doors of a car simultaneously, either through a remote or when the driver's door is locked. This feature offers several benefits to car owners:

- Enhanced Safety and Security: The central locking system utilizes sophisticated computer systems to detect if any car doors are left open. Warning lights, typically displayed on the speedometer, caution the driver accordingly. Moreover, the system is linked to an alarm, reducing the risk of car theft.

- Convenience: With just a click of a button on the key fob, the driver can take control of all the car's door locks, even from outside the vehicle. This makes locking and unlocking the car a breeze.

2. How Does a Central Locking System Work?

The central locking system operates based on key codes and radio waves. The car key acts as a transmitter, and the car acts as a receiver. When the key sends a command, the car responds only if the codes from the key and the receiver match. Additionally, when the car is locked using the key, the immobilizer is activated, preventing unauthorized access and potential theft.

In modern cars, the central locking system is power-operated and significantly more advanced than older systems.

3. The Central Locking System Components

The central locking system comprises four main components:

a) Actuator: The actuator contains pistons and gears that work together to lower the shaft connected to the door lock. It is responsible for operating the lock and plays a critical role in the entire locking system.

b) Transponder: The transponder is located in the key bow and is responsible for reading and matching codes, enabling the engine immobilizer to start or stop the engine. In vehicles with keyless entry, the immobilizer detects the transponder code as soon as the key is in proximity, allowing the engine to start.

c) Key Fob: The key fob is a remote control that enables keyless entry into the car. It not only locks and unlocks the car but may also control other functions like opening the trunk or turning on the lights.

d) Start/Stop Button: The start/stop button is a convenient feature that often replaces the need for a traditional key. Pressing the button starts the ignition and activates various devices powered by the car's battery.

4. Reasons for Central Locking System Malfunctions

Diagnosing issues with the central locking system is generally straightforward due to its simple functioning. Common reasons for malfunctions include a faulty solenoid, blown fuse, internal wiring problems, or a drained key fob battery. Additionally, a central locking mechanism may malfunction if the car battery is dead since the system requires power to operate effectively.

Car Central Locking FAQ’s

1. Is Keyless entry the same as central locking?

Ans. No, keyless entry and central locking are not the same. Central locking involves all doors locking or unlocking simultaneously when the driver door lock is engaged or disengaged. Keyless entry, on the other hand, uses a remote control key with buttons to operate the functions of a normal key, eliminating the need to physically insert the key into the lock. Keyless entry systems often include a separate button to start the ignition.

2. Why do car doors automatically lock when driving?

Ans. Cars may have a feature called auto-lock, which automatically locks all doors when the first gear is engaged. This is a safety measure to prevent young children from accidentally opening the doors while the car is in motion. Some cars may also have speed-sensing door locks, which engage when the vehicle reaches a defined speed, usually around 10 km/h (6 mph).

3. How much does car central locking cost?

Ans. The cost of an aftermarket car central locking system typically ranges from 3000 to 4000 rupees, depending on the brand and features. Reputable brands like Nippon offer quality central locking systems. Many new cars come equipped with central locking, but you can also install an aftermarket system in older vehicles.

4. Which is the best central locking system for a car?

Ans. There are several reliable brands that offer central locking systems for cars. Some of the popular and best-known brands include Nippon, Autocop, and blackcat. It is recommended to choose a system that suits your specific car model and needs.

5. Why is my central locking system not working?

Ans. There could be several reasons why a central locking system isn't functioning properly. Some common issues may include:

- Blown fuse or internal wiring problems.

- A faulty actuator responsible for locking and unlocking the doors.

- A dead or malfunctioning key fob (remote control key).

- A dead car battery, which may prevent the central locking system from operating.

If you encounter any problems with your central locking system, it is best to take your car to a qualified mechanic for diagnosis and repair. They can identify the specific issue and provide the necessary solutions.

Conclusion:

Car central locking systems offer remarkable convenience, safety, and security to modern vehicle owners. Understanding the purpose, components, and working of this vital feature can help car owners troubleshoot and address any issues that may arise. Regular maintenance and addressing malfunctions promptly can ensure the smooth functioning of the central locking system, enhancing the overall driving experience.
