Acura 2009 Accord Sedan - Manual (Page 149)

CONTINUED
You should have received a key
number tag with your keys. You will
need this key number if you ever
have to get a lost key replaced. Use
only Acura-approved key blanks. Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON Mode is the equivalent of
ON (II). See page
for ignition
switch and power mode comparison.
The system may not recognize your
key’s coding if another immobilizer
key or other metal object (i.e. key
chain) is near the ignition switch
when you insert the key or set the
power mode to ON. When you turn the ignition switch to
the ON (II) position, the immobilizer
system indicator should come on
briefly, then go off. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to the
LOCK (0) position, remove the key,
reinsert it, and turn the ignition
switch to the ON (II) position again.
The immobilizer system protects
your vehicle from theft. If an
improperly coded key (or other
device) is used, the engine’s fuel
system is disabled.
