Reasons to get a car central locking system
Car central locking system is an integral part of modern
cars. This smart device allows you to easily block the access of unauthorized
persons to your vehicle. Let's take a closer look at this mechanism, how it
works, what are its advantages, installation peculiarities and repair methods.
What is
central locking in car
The central locking system is a mechanism that allows you
to close and open access to your car. By pressing a single button, you can
simultaneously block all the doors of a vehicle, as well as its trunk door,
fuel cap, and in some cases also lift all windows. In the past all these had to
be closed individually, which obviously was time-consuming not so convenient
and safe. Now modern cars are hard to imagine without centralized blocking.
In addition, central locking is connected to the alarm
system, which is triggered when someone tries to open locked doors. Moreover,
when you lock a car door, at the same time, you also block its engine. The
motor will not start until you unlock the door with a key with a unique
electronic code.
Thus, the central locking system is an essential
element of security, which makes it extremely difficult to penetrate a car and
steal it.
If you need to block the vehicle when you are in its
cabin, you can click the corresponding button on the dashboard. Unlocking also
happens when you turn the key in the driver’s door lock. Outside the vehicle
you can also use a remote control. It not only enables to lock and unlock the
car on distance, but also makes it easier to find a vehicle among other cars in
the parking lot, since unlocking is accompanied by a characteristic click and
flashing headlights.
Recently, keyless locking systems are increasingly
implemented in cars when an electronic card instead of a key with a remote
control is used. You do not need to press a button to unblock the car — it
happens automatically when you approach it at close range.
If you own one of the old car models and the central
locking is not provided in it (or for some reasons central locking does not
work), you most likely want to install it or repair an existing one.
How car
central locking system works
What is center lock in car in terms of its construction
and functioning? The main elements of any automotive central locking system
are:
• sensors;
• control block;
• actuators.
When you turn the key in the driver's door keyhole, a
microswitch is activated in it, which is responsible for locking. From the
microswitch, the signal is transmitted to the central unit, which sends
commands to the actuators of all the other locks, which block or unblock the
doors, hoods, gas cap, etc.
When using the remote control, the signal immediately
goes to a central control unit, which then sends commands to the locking
devices. If you block the car, then all the unclosed windows in it
automatically rise. The range of such remote control systems is about ten
meters. Of course, central locking system keeps working regardless of whether
the car is turned on or not.
In case of an accident, doors are unlocked automatically.
Such a function is provided by the passive safety system, which sends the
corresponding signal to the central control unit. This option allows you to get
out of a damaged car as quickly as possible.
Thus, central lock performs several functions:
- locks the door;
- enables and disable the alarm;
- automatically lifts all unclosed windows.
In addition, for even greater convenience, you can
program some functions of a central lock in advance. For example, you can
configure the system so that all doors are automatically locked at a speed
exceeding 10 km h or the trunk is locked at a speed of 5 km/h. Some drivers set
up central locking so that first you can open only the driver’s door, only
after it, all the other doors can be opened.
Reasons to get a car central locking system
Basically there two main reasons to have a car central
locking system: safety and comfort.
Security
To be absolutely sure about your car when you leave it,
you need to block access to it as much as possible. In former times, you could
do this by closing all the doors, hoods and fuel caps separately. In addition,
you had to check whether all windows are closed and whether the alarm is on (if
there was one at all). You could simply forget to do something from the listed
above and leave your car vulnerable to penetration and theft.
Comfort
The second reason to get a car central locking system
is inextricably linked with the first. It is the convenience of locking the car
that contributes to its safety. By pressing just one button, you block all the
doors, lift windows and turn on the alarm. You do not need to worry that you
forgot to do something.
How to
install central locking system in a car
If you need to install the lock by your own means, first
purchase central locking system kit (you can easily do it online) Then follow
this short manual:
• remove the trim on the doors. Note that during the
removal process, fastening clips will be damaged. For re-installation, you have
to buy new latches (buy them in advance);
• remove terminals from the battery;
• find a suitable place to install the central
locking control unit. Note that it should not interfere with the work of other
mechanisms;
• fix the control unit with self-tapping screws and
connect the system to closing buttons of doors;
• connect wires to the central locking unit. To do
this, follow the manufacturer’s recommendations given in the guide;
• connect the previously removed terminals to the
battery;
• as soon as the installation of the central lock is
completed, check device for operability.
How to fix
car central locking system
There are several types of central lock faults that can
be fixed fairly easily.
Wire
breakage
Various kinds of careless actions by a motorist, when
dismantling or repairing doors, can harm and lead to a break in the electrical
wire. You need to take a check on the electrical circuit in order to determine
location of damage and repair it.
Broken relay
This is another reason for the malfunction of a central
lock. To repair it, you need to repair or replace it.
Control
board malfunctions
You should consider its repair or replacement.
Worn
actuator gear
The first to suffer are plastic gears. You need to
replace them with new ones.
Anyway, you should have a properly working central
locking system in your car. Only with it, your vehicle will be safe even when
you are not around.
