Every motorist dreams that his car is safe. The ability to block immediately all the doors not only with the key, but also using keyrook, at a distance. This is not only a security deposit, but also convenience. This type of castle is central - today is very popular. However, not all cars are equipped with a central lock in the factory assembly, so car owners have to establish such systems independently. To determine which castle to choose, you need to know all varieties and differences between them. There are several types of locks that differ in their typical characteristics.

What you need to know about the central castle to make the right choice
From the point of view of functionality, the central locking is very convenient - so you can control the locking of the doors in the car. The signal from the key fob is sent to the control unit, from where it is transmitted to the center of control of the central locking, enters the door lock system, where the signal is created for the door control systems. Control blocks control the activator, which is responsible for the state of the doors. Much more practical and more convenient to choose a central locking system that does not only block the doors, but also connected to the alarm. This improves the quality of the protection and reliability of the machine - along with the remote connection of the alarm the doors are blocked. What is important, any central locking operates both when the ignition is turned on and when the ignition is turned off.
Factory locks are offered, which are created specifically for a specific car model, but this option is very expensive and only suitable for a specific machine.

You can independently assemble a modification that will cost somewhat cheaper, but it is sometimes quite problematic to choose the necessary option.

The universal central locking is suitable for any machine, they are sold in specialized salons and auto parts and alarm systems. Almost all sets of central locks consist of the following fixtures:
- set of wires;
- controller;
- cables;
- fasteners;
- More complex locks - a control panel.
Functional differences in central locks
In general, the essence of the work in all types of central locks is one. Special sensors are determined in what condition the doors are open or closed. The control unit analyzes the sensor data and determines the necessary operation of the lock. The actuator is the DC source. All castle electric motors work according to one principle, but they differ in charge. The driver's keychain acts as an antenna that allows radio channels to transmit signals to the actions, opening or closing the door. Today, only electrical central locks are offered, earlier in some models of the car there was a pneumatic version of the castle, but the production of such a format is completed. When you lock the doors, all closing buttons are automatically taken off. In case of an accident, when airbags are triggered, the doors will automatically open.
The layout of the elements of the central locking system.
Before you decide which lock to choose, it is necessary to decide, the performance of what functions you expect from it. Each manufacturer and castle class has a set of actions. So, modern central locks are capable of much:
- control over the state of the doors in the car;
- control over the door of the trunk;
- Opening / closing of the hatch of the fuel tank;
- closing windows (if electrical generates are built into the machine);
- Locking a hatch in the ceiling (if any).
Pretty useful is the ability to close the windows with the help of the central lock. As practice shows, the driver opens the windows, and then forgets to close them, this is an excellent opportunity for hijackers.
No less important is the ability to partially block the doors. It is especially useful to choose such a castle to those who often transport children. If necessary, you can receive additional properties such as automatic locking of doors and trunk (when the machine is accepted to a certain speed) and the safety unlock (first - only the driver's door, and only then, from the second press, the rest). For those who doubt the need for a central lock, it is possible to connect such a function in a simplified version - the system will only block the front doors. But in this case, security is reduced, often drivers simply forget to close the rear doors.
Before buying a castle, think about which of the proposed functions will be useful to you, so as not to overpay for what you do not plan to use.

All central locks for functioning are reduced to 2 main types:
- Mechanical central locking;
- Remote door lock.
The mechanical closure of the doors occurs by turning the normal key in the lock, most often this function is located in the driver's door. You close one - all others are automatically blocked. Remote service is served using a key fob or buttons on the ignition key. Of course, the mechanical option is easier and more reliable. Remote can sometimes be jammed for many reasons - from a discharged battery and a poor-quality mechanism to the seal batteries in the key.
Initially, all locks were made with a centralized control unit, however, over time, the emergence of additional functions, such as blocking the door of the trunk or fuel hatch, demanded decentralization in control.
Today, manufacturers offer a variant of the central lock, combined with the alarm. This option is quite practical, since all security systems work synchronously, which increases the safety level of the car. In addition, the central lock with the alarm is more convenient to install - do not need to visit the car service or disassemble the car itself several times.
How to choose a manufacturer of the central lock?
When choosing a central castle, it is worth considering the country and manufacturer's company. Devices from China are a very affordable and budget option, however, high risk that such a lock will serve you for a short time. Doubtful manufacturers even meet castles or their components that are not initially approaching your car. Therefore, before buying it is worth carefully checking the craving, fasteners, a complete set of details. However, in recent years, Asian manufacturers have greatly increased in the aspect of the quality of goods produced, so you can get caught and an excellent, reliable copy.
Choosing the manufacturer of the Central Castle, first look at the price - the quality lock should not be cheap, otherwise the risk is the risk that one day the door is simply evincible - this is often found quite often. It is especially dangerous to buy the castle not in a specialized store, but "from the hands" and from unverified sellers. The company "Dragon" and "Alligator" have proven quite well.
