Key Code Erasure

This function allows the user to erase all the Key Codes for Transponder Keys except the Registered Master Key used during this function. The following screens show how to perform Key Code Erasure.

HINT:
This function requires the use of one Registered Master Key. The use of a Sub Key will NOT complete Key Code Erasure.





1. From the "KEY CODE UTILITY" menu (Screen A), select [2: KEY CODE ERASURE).





2. Confirm the instruction on Screen B and press the (ENTER) key.





3. Confirm the instruction on Screen C and press the (YES) key.

NOTE:
By pressing the (YES) key, all Transponder Key Codes will be erased except the Registered Master Key in the Ignition Cylinder.

HINT:
After pressing the (YES) key, the Security Indicator will start to flash.





4. Pull out the Registered Master Key from the Ignition Cylinder within 10 seconds (Screen D).

HINT:
Security Indicator continues to flash.





5. If Step 4 was completed correctly, Screen E will confirm ERASURE was successful.

HINT:
If the Erasure completed, the Security Indicator should still be blinking.





6. Insert the Registered Master Key into the Ignition Cylinder and turn to the ON position and press the (ENTER) key.

HINT:
Look at the Security indicator Light. Inserting a Registered Master Key causes the Security Indicator to immediately stop blinking.
