IMMO Service
An immobilizer is an anti-theft mechanism that prevents an automobile’s
engine from starting if the correct ignition key is not used or other device is
present. This device prevents thieves from starting the vehicle by a method
known as hot wiring. Most new vehicles have an immobilizer as standard
equipment. An important advantage of this system is that it doesn’t require
the vehicle owner to activate it; it operates automatically. An immobilizer is a
more effective anti-theft protection than an audible alarm alone; many auto
insurance companies offer lower rates for vehicles that are equipped with
them.
As an anti-theft device, an immobilizer disables one of the systems needed
to start a vehicle's engine, usually the fuel supply or the ignition. This is
accomplished by radio frequency identification between a transponder in the
ignition key and a device called a radio frequency reader in the steering
column. When the key is placed in the ignition, the transponder sends a signal
with a unique identification code to the reader that relays it to a receiver in
the vehicle's computer control module. If the code is correct, the computer
allows the fuel supply and ignition systems to operate and start the vehicle. If
the code is incorrect or absent, the computer disables the system, and the
vehicle will be unable to start until the correct key is placed in the ignition.
The IMMO service of MK808 enables you to disable the lost vehicle keys and
program a replacement key fob. One or more replacement key fob can be
programmed, depending on your needs.
To program the replacement key fob(s)
1. Tap IMMO KEYS after entering the Service function from the
MaxiCOM Job Menu.
2. Tap Automatic Selection or Manual Selection to acquire vehicle
VIN information and tap Yes to confirm.
3. Tap Erase/Program all key fobs in the IMMO function list after it is
displayed, the list may vary for different vehicles being tested.
