A voltmeter should be used to locate circuits on the latest year cars so as not to damage the wires.
Central locking device
The central lock is a complex unit with an electromechanical drive.
The central lock consists of the following components:
Control block
Sensor and button input
Executive device (actuator)
Central locking device
The trunk lid and fuel filler flap can also be fitted with a locking device connected to the central lock.
Control block
CU verifies the position of "Limit switches", controls, as well as contact groups of door locks and other sensors which are connected to the unit by wires.
Initially, the electronic components of the unit were contained in the housing with connectors. However, in newer vehicles, the CAN bus is also used, the central locking system can be divided into separate components. This allows them to be installed in different places of the body.
Send a signal to "Turn signals", which flash briefly when locked / unlocked. With this option, the alarm can be connected to the appropriate wires and the turn signal is associated with its function.
Receive signals from the remote control If this receiver is out of the unit, a connection cable can be used to control the car alarm.
If the central locksmith Columbus Ohio has a multifunctional complex control unit, most of the wires of the installed security system are connected to the connector. Separate connections are required for the siren, alarm sensor and engine blocking device, if applicable.
Sensor and button input
The central locking system consists of several groups of input sensors that are used when installing an alarm:
Which includes:
A "limit switch" is a car door end sensor that determines the closed or open position. The corresponding power to the lights in the cabin depends on their signal.
Micro switch door lock They signal the closed / open state of the car door lock.
Micro switch in electric lock drive They give a signal about the status of the door locking device - lock / unlock.

Executive equipment
There is an electric drive and a pneumatic drive of a central locking device (actuator).
Pneumatics are no longer used in the design of central locking in modern cars, electric drives are used everywhere.
Electric drive
There are different types of electric drives with different designs, with a pull force of 2.5 - 6 kg. The most common types are square and T-shaped ("pistols").
The electric drive mechanism is housed in a plastic case. The structure consists of an electric motor and a metal gearbox. (Or plastic) When the polarity of the voltage applied to the motor is reversed, the shaft rotates clockwise or counter-clockwise. Torque is transmitted to the gearbox, which converts rotational motion into translational motion. The direction of rotation determines whether the door lock is locked or unlocked.
Electric powered door lock circuit
Among the electric drives are two electric motors. One is used to turn off / on the lock, the second - blocks the mechanical drive of the locking device from opening from the car using a handle or pull rod. These electric drives are controlled by three wires.
The electric motor differs in quantity or does not have a tactile microswitch connected mechanically with a rising rod. Two motor wires are combined with three switch wires to form a five-wire motor.
It is usually installed in the front door of the vehicle and the micro-switch sends a signal to the two electric motors found in the rear door 24 hour locksmith. Related commands (To close or open) will be sent when the front door is locked or unlocked with a key or when a control button is pressed.
