1. Transponder Key Type
Before any Immobilizer functions are performed, verify the type of transponder key
that you are attempting to use for the service operation. Some functions may only be
performed with a registered Master Key.
2. Transponder Code Registration
This function allows the registration of additional transponder keys (Master or Sub)
using a registered Master Key.
3. Transponder Code Erasure
This function allows the user to erase all the transponder keys except the registered
Master Key used during this function.
4. Transponder ECU Reset
This function allows the registration of a new Master Key even if all original Master
Keys are lost. Once the Immobilizer system is reset, all previous registered keys will
be erased.
5. Transponder ECU Replacement
When the Transponder ECU is replaced, the transponder keys must be registered to
the new ECU, auto registration closed, and ECU communication completed.
6. Engine ECU Replacement
When the Engine ECU is replaced, ECU communication must be completed to
synchronize an encrypted security code between the engine and Transponder ECUs.Function

2. Transponder Code Registration
This function allows the normal registration of additional transponder keys (Master or
Sub) using a registered Master Key.
NOTE:
This function requires the use of one registered Master Key. The use of a Sub Key will
NOT complete Transponder Code Registration. Attempting registration of additional
keys with only a Sub Key will result in errors and incomplete registration.
HINT:
The Immobilizer key blanks are preconfigured as Master or Sub Keys. Master Key
blanks cannot be registered as Sub Keys nor can Sub Key blanks be registered as
Master Keys. Also, the flat key is now enabled as a full function Master Key that must
be registered.
A. Insert a registered Master Key into the ignition cylinder and turn to the ON position.
B. Follow the screen flow in Figure 2 to register new Master or Sub keys. It is
possible to register up to 5 Master Keys and 3 Sub Keys.
C. Be sure to follow the instructions on key insertion, ignition ON/OFF and key
removal exactly as described on the Diagnostic Tester.
