Immobiliser

The model Octavia II features the immobiliser of the fourth gen‐
eration. An essential component part of the immobiliser of the
fourth generation is a central database, in which all theft-related
data of the control units involved are stored. As of 2007, it is no
longer possible to adapt the immobiliser control units according
to the engine without online connection to this database.
In vehicles manufactured up to MY 2006, the immobiliser control
units can also be adapted (if no PIN for the immobiliser is avail‐
able) via an online connection ⇒ Vehicle diagnostic tester
♦ A PIN code request of the immobiliser components by fax or
temporary activation of the components is not possible.
♦ All the components of the immobiliser must be initialised online
(not necessary for vehicles manufactured up to MY 2006).
♦ In Škoda vehicles it is no longer possible to adapt the compo‐
nents of other corporate brands.
Vehicles manufactured as of MY 2007, which must be coded on-
line (depending on the engine):
♦ All - even re-ordered - ignition keys are already precoded at
the factory for a specific vehicle and can only be initialised for
this vehicle.
♦ When re-ordering ignition keys, the relevant vehicle identifi‐
cation number must be provided.
