Coding erasure
With two keys coded for your
vehicle you can make all the other
coded keys unusable, e.g. after loss.
Complete each of the following
steps within 10 seconds.
Carry out the first four steps under
Key coding, then continue as
follows:
5. Insert the second key in the
ignition switch again and turn to
position II.
6. Remove the key from the
ignition switch.
7. Insert the first key in the
ignition switch, turn to position II
and hold. The indicator light flashes
for 5 seconds.
Locks (security)
8. If the ignition is switched off
during these 5 seconds, the erasure
process is terminated and no key is
erased.
9. If the erasure process is
completed, all the other keys, apart
from the two used for erasure, can
no longer be used unless recoded.
Additional keys can now be coded.
