Acura 2012 TL - Manual (Page 153)

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.
The immobilizer system protects
your vehicle from theft. If an
improperly coded key or keyless
access remote (or other device) is
used, the engine’s fuel system is
disabled.
When you turn the ignition switch to
the ON (II) position, or select the
ON mode with the engine start/
stop button, 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 or
keyless access remote.
On models without keyless access
system, 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.
On models with keyless access
system, set the power mode to
VEHICLE OFF (LOCK), then select
the ON mode again.
The system may not recognize your
key’s or remote’s coding if another
immobilizer key or other metal
object (i.e. key chain) is near the
ignition switch or the keyless access
remote when you insert the key or
set the power mode to ON.
