FAQ on Smart Key Code Saving Feature

Q1. What is the Smart Key Code Saving feature?

A1. The Smart Key Code Saving feature in the S/W Management menu allows you to register a new smart key by entering the KEY PIN into the vehicle’s controller (IBU).

Q2. How is the smart key PIN CODE set when the vehicle is delivered?

A2. When the vehicle is first produced at the factory, the initial key PIN CODE is registered in the IBU. This PIN can be checked through the GSW system and is required when registering a new key.

Q3. In what cases does a PIN CODE error occur when registering a Smart Key?

A3. There are two main cases:

1️⃣ When an incorrect PIN CODE is registered in GSW

• If an incorrect value different from the actual PIN was mistakenly entered when the initial PIN was registered in GSW at the factory
• In this case, registering a new key will continue to fail using the PIN retrieved from GSW.
• Since the PIN registered in GSW is incorrect, no matter how accurately it is entered, it will not match the PIN stored in the IBU, causing authentication failure.

2️⃣ PIN CODE input error after IBU replacement

• If the IBU has been replaced after the vehicle was delivered, and an incorrect PIN was entered/stored in the replaced IBU at that time.
• If, instead of entering the existing PIN retrieved from GSW, a different PIN is mistakenly entered, that value will be saved in the newly installed IBU.
• As a result, the PIN retrieved from GSW and the actual IBU PIN will not match, causing new key registration to fail.

Q4. How should the PIN CODE be managed after controller replacement?

A4. The following procedures must be followed:

1. After IBU replacement, accurately update the PIN CODE in GSW.
2. Verify that the PIN retrieved from GSW matches the value stored in the actual IBU.
