ANTI-THEFT DEVICE - IMMOBILIZER
E - KEYS:
An E-Key is an electronic access and
authorization system which is provided
as a standard feature on your vehicle.
Your vehicle is provided with an
E-Key. Each Key is specific to the
immobilizer of your vehicle.
Unlocking principle:
The transponder which is built into the
ignition E-Key carries a unique identi-
fication code. The vehicle unlocks when
the code on the E-Key matches with
the code on the Body Control Module
(BCM).
Engine Starting:
When the key is inserted and the
ignition is switched 'ON', all codes are
communicated within concerned
components (E-Key, Immobilizer and
EMS). The engine will start only if all
the codes match.
Loss of keys :
If one of the E-Key is lost, contact your
nearest TATA MOTORS authorised
dealer as soon as possible to have the
lost key deactivated. The second
original E-Key is required for making
additional E-Keys. If both the E-Keys
are lost contact TATA MOTORS
authorised dealer.
WARNING
1. Do not turn 'ON' ignition switch
by using E-key with any type of
metal wound around its grip or in
contact with it. This may be
detected as abnormal condition
by immobilizer and prevent
engine from starting.
2. Do not leave the E-key in areas
of high temperature. The
transponder in it will behave
abnormally when reused.
3. Do not try to start the vehicle
when the Immobilizer indicator
SAFETY
lamp on the instrument cluster is
glowing. In this condition the
vehicle will not start and the
vehicle's battery will also be
drained due to frequent cranking.
