IMMOBILIZER SYSTEM
7-75
EAS27671
GENERAL INFORMATION
This vehicle is equipped with an immobilizer system to help prevent theft by re-registering codes in
the standard keys. This system consists of the following:
• A code re-registering key (with a red bow)
• Two standard keys (with a black bow) that can be re-registered with new codes
• A transponder (installed in the key bow)
• An immobilizer unit
• The ECU
• An immobilizer system indicator light
The key with the red bow is used to register codes in each standard key. Do not use the key with the
red bow for driving. It should only be used for re-registering new codes in the standard keys. The
immobilizer system cannot be operated with a new key until the key registered with a code. If you
lose the code re-registering key, the ECU and main switch (equipped with the immobilizer unit) need
to be replaced.
Therefore, always use a standard key for driving. (See caution below.)
TIP
Each standard key is registered during production, therefore re-registering at purchase is not neces-
sary.
ECA14971
• DO NOT LOSE THE CODE RE-REGISTERING KEY! If the code re-registering key is lost, reg-
istering new codes in the standard keys is impossible. The standard keys can still be used
to start the vehicle. However, if code re-registering is required (e.g., if a new standard key is
made or all keys are lost) the entire immobilizer system must be replaced. Therefore, it is
highly recommended to use either standard key for driving, and to keep the code re-regis-
tering key in a safe place.
• Do not submerse the keys in water.
• Do not expose the keys to excessively high temperatures.
• Do not place the keys close to magnets (this includes, but is not limited to, products such
as speakers, etc.).
• Do not place heavy items on the keys.
• Do not grind the keys or alter their shape.
• Do not disassemble the key bows.
• Do not put two keys of any immobilizer system on the same key ring.
• Keep the standard keys as well as other immobilizer system keys away from the code
reregistering key.
• Keep other immobilizer system keys away from the main switch as they may cause signal
interference.

PART REPLACEMENT AND KEY CODE REGISTRATION REQUIREMENTS
In the course of use, you may encounter the following cases where replacement of parts and regis-
tration of code re-registering/standard keys are required.
TIP
Each standard key is registered during production, therefore re-registering at purchase is not neces-
sary.
