As an anti-theft device, an immobilizer disables one of the systems needed
to start a car'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, which 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
car. If the code is incorrect or absent, the computer disables the system, and
the car will be unable to start until the correct key is placed in the ignition.
The IMMO service of MX808TS enables you to disable the lost vehicle keys
and program the replacement key fob. It could be one replacement key fob
or more, depending on your needs.

MaxiCheck Job Menu.

displayed, the list may vary for different vehicles being tested.
