8.22 IGNITION E-KEY
An E-Key is an electronic access and
authorization system which is provided as a
standard feature on your vehicle. Vehicle is
provided with two E-Keys. Each Key is specific to
the immobilizer of vehicle.
Unlocking principle:
The transponder which is built into the ignition E-
Key carries a unique identification code. The
vehicle unlocks when the code on the E-Key
matches with the code on the Engine
Management system (EMS).
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.
