[English] How Immobiliser Works?

hello everyone welcome to the automotives
today we will discuss what is immobiliser and how it works?

........................................................INTRO......................................................

nowdays in modern automobile era almost every premium car is equipped with
immobiliser. who increase the anti-theft quality of vehicle.
immobiliser is advace security system who uses the advance techniques to
identify the original car key and prevent vehicle hijaking with duplicate masterkeys!
today in this video we will discuss
what is the meaning of immobiliser?
construction on immobiliser.
and at last working of immobiliser!

MEANING:::::

immobiliser is a advanced security device eqqiped in modern automobiles
who prevents the car from hijacking by identifing the original transponder
key thorugh is special coded signals. immobiliser is so well designed that
it control fuel injection system and Ignition system which allows to prevent
the car starting even after the bypassing ignition switch.in short immobiliser
is advanced security device who improves the anti-theft capabilities of vehicle.
CONSTUCTION::::::

immobiliser is a built in feature in ECU of a car.
but to understand it easily we use an animated diagram.
normally with the ECM of vehicle engine management unit
and electronic ignition system are connected which are controlled by it.
other then that the car key dock of vehicle contains the electromagnetic coils

which are conntected and controlled with the ecu.

in standerd car key, a transponder chip is kept hidden inside the plastic cover.
this transponderc chip contain the copper coil and hardcoded signal transponder circuit.
in case of keyless entry the transponder chip is often connected with the battery kept inside
the remote.
WORKING:::::::::::

when you insert the key in your car, the magnetic field generated by magnetic coil
is intrupted by copper coil inside the key, as per the faradey law current is produced
inside the coil which powers the transponder.
transponder broadcast the special coded signals which is later recieved by ECU.
ECU identify the Key code and confirm that the key is genuine and thus it starts the
ignition as well as the fuel injection, and later engine starts!

if you insert the duplicate key it transmit the wrong code or even dont transmit the code
which means ECU fails to identify the keys and thus engine can not be started due to
igntion and fuel system cut off!

incase of the keyless entry the transponder uses the remote battery and transmits the
signals which further recieved by the ECM and thus car can be started!
