Replacement keys
Replacem ent keys are available exclu-

your BM W center is obligated to ensure
that a person requesting a key is autho-
rized to do so (refer to "Electronic

page).
If possible, take all of the m aster

Whenever you receive a new replace-
m ent key, turn that key to position 2 in
the ignition lock once (ignition sw itched
on) and then back. This allow s the elec-
tronic vehicle im m obilizer to "learn" the
new key.<
