A car central locking system is a system that allows the driver to remotely lock or unlock all the doors of a vehicle with the push of a button. This system is often integrated with other features such as an alarm system and can be controlled through a key fob or a button on the car's dashboard.
The central locking system circuit consists of a control unit, door lock actuators, and a central locking switch. The control unit is the brains of the system and is responsible for receiving signals from the central locking switch or key fob and activating the door lock actuators. The door lock actuators are small motors that are installed inside the door panels and are responsible for physically locking and unlocking the doors.
The central locking switch is usually located on the dashboard or center console of the car and allows the driver to manually lock or unlock the doors. It may also include a panic button that can be used to trigger the alarm in case of an emergency.
To understand how the central locking system circuit works, let's consider an example where the driver wants to remotely lock the doors of the car using the key fob. When the lock button on the key fob is pressed, it sends a signal to the control unit through a wireless connection. The control unit receives the signal and activates the door lock actuators, causing the doors to lock. When the unlock button on the key fob is pressed, the control unit receives the signal and activates the door lock actuators to unlock the doors.
In addition to the central locking system circuit, most modern cars also have a passive locking system that automatically locks the doors when the car is put into gear or reaches a certain speed. This helps to improve the security of the car and prevent unauthorized entry.
Overall, the car central locking system circuit is a convenient and important feature that enhances the security and convenience of a vehicle. It allows the driver to easily and securely lock and unlock the doors of the car, and can also be integrated with other features such as an alarm system.
Build a Homemade GSM Car Security System
Keep the keys and remote control away from any source of electromagnetic field TV, computer, speakers, mobile phone as the electromagnetic field emitted by these devices may disturb the frequencies in the key electronic circuit. This is where the door pistons will be needed. The winding of the motor is connected between M1 and M2 in the schematic. Also, when you leave the car and the card is at some distance from the receiver, it gives the command to close the doors automatically. If you additionally use a layer of duct tape, the likelihood of wire breakage will be practically zero. If you want to use a capacitor, you will need a resistor to make a timing circuit and likely a transistor to amplify switch the power to the relay.
Central locking in the car: structure and principle of work
The signals sent by each sensor go to the control unit, which transmits commands to the actuators that close the doors, trunk lid and fuel tank hatch. As an additional, but very useful element of comfort are used window closers. Thanks Dear Sir, Good day, we would like to inquire about the assembled kit of your homemade gsm car security system. The system uses a wiring harness to connect the doors, trunk, and engine. This stage is rightly considered the most difficult and demanding in terms of quality of work performed. The diode inputs D3 and D8 react to a rising edge, R6 and R8 react to a falling edge. The first step is to clean and lubricate the door lock cylinders.
Installing central locking
These are micro-switches as well as limit switches for all existing car doors. This is the output wire positive out. Checking the wiring harness for damage is an essential step in troubleshooting the central locking system. Cell phones have always intrigued me for the simple reason that, these gadgets are so compact and sleek in appearance and yet are able to do the monstrous task of sending signals wirelessly across the globe within seconds. In the case of remote control with changing code, the transmitter code will no longer be the same as the receiver. This has been confirmed at the door actuator which has 2 wires. After all, exactly central locking allows you to remember to close all the doors, performs the function of window closer, prevents unauthorized attempts to drain fuel from the gas tank or get into the car through the luggage compartment.

The central unit is used here as well, but in addition each door has its own separate control unit. Swagatam, have you tried with any telecommunications service provider? Some kits come with all the necessary elements, from 2 remote controls and the central unit, to connection cables and clamps. There are two types of alarm available, with positive or negative control. Avoid leaving keys in a humid environment kitchen or toilet, for example as they contain electrical circuits that are very sensitive to moisture. The coil of relay extreme left is connected externally to the door switch of the vehicle. How much does it cost and could you teach us how to install it if ever we avail it.
Infrared Controlled Car Door Lock
And accidentally pressing the buttons on the remote control while in your pocket, for example , when it is within range near the car, can inadvertently unlock the doors. New car models have power-operated car lock Then, if you unlock the front door manually, it will also open the other doors. Radio remote controls also use a skip code, which means that after locking, the transmitter and receiver will change the pre-programmed code. It should run from the drive unit, parallel to part of the existing link rod. The central locking system is an essential feature that manufacturers have been adding to cars for over a decade. Use clamps and insulating tape in the process to combine multiple wires into one bundle in different areas along the entire length of the wiring.
