Good news — the Keydiy KD-X4 key programmer can now modify the ID of original factory VAG MQB49 5C and 5D keys. In previous versions, the KD-X4 could only change the ID of KD’s own 5C/5D keys (check this guide). With the latest update, the KD-X4 can also change the ID of original keys.

Fairly new update within the past few days.

Changing the original key ID willtake 100 coinseach time.

Done a VW ID.3 2021 MQB49 5D key. Changed factory key ID. Cost 100 coins to do so. No SFD lock.
5D done today for an ID.3 2021, changed factory key, cost 100 coins to do so.

Used OEM board, second hand from ebay. Worked a treat, carefully split case, then glued together and reassembled. No one will even know. It does cost 100 coins to rewrite original board ID, but did the job.

To be fair KD FGB would be a better option with the wireless remote generation. Without KD solderless adapter, you have to solder wires on the original key.

NOTE:

Modify the ID of KD’s FGB remote does not require points.

CGDI K2 and Yanhua ACDP will also modify OEM 5C/5D key ID.

PIN CodeOverview:

The DUCATIPINcode is a 4-digit security password. Its primary function is to serve as an emergency unlock credential for the Immobilizer System (IMMO) and to facilitate critical anti-theft data programming.

1). If the key transponder fails, the fob battery is dead, or the vehicle experiences an immobilizer malfunction or lockout, the PIN must be entered via the dashboard to unlock the vehicle ;

2). Factory default PINs are often generic (e.g., 0000 or a specific combination) and can be modified via the instrument cluster menu to a personalized code, preventing unauthorized access ;

3). If the PIN is not stored correctly or is lost, the vehicle may be restricted from starting, or the dashboard menu may prevent changes. In such cases,MOTOMASTER'sPIN Code Resetfunction is required to resolve the lockout.

Preparation:MOTOMASTER, M001A, M041.

Solution

Solution:Use OBDSTAR MOTOMASTER to performPIN code resetfunctiontoreset PIN code.

Detail Steps:

SelectMOTO Diag--DUCATI--Latest Version to enterDiagnosis;

ChooseBy model；

Sequentially selectD>Diavel 1260 E5>1262>MY 21;

ClickManual selection；

ClickHands Free (Smart Key)and tapEnter；

ClickSpecial Function, follow the prompts, enter the password123, ClickOK;

ClickOK;

Operation complete. The PIN code has been reset. You may now proceed to the instrument cluster menu to change the PIN code.

Manual PIN Change Procedure

1). Turn the ignition switch to the ON position;

2). Wait for the dashboard to display the home page, then press and hold the MENU ENTER button on the left handlebar to access the dashboard menu;

3). Select thePIN CODEfunction from the menu;

4). Enter the reset PIN: 0000;

5). Set a new PIN to complete the modification.

Today we’re working on a 2025 Chery Arrizo 8. The car belongs to a taxi company. Our task is to add a spare key.

There are no risks associated with adding keys to these vehicles. It’s all done via the OBD2 port and takes 10 minutes.

Usingxtool x100 pad3/pad2 device withKC501 programmer.
Read pin code ok.
Program key ok.

In this case, the owner needed the original key and a full rebuild (along with an emergency mechanical key for opening the door).

1. Open the car.
2. Read the PIN code.
3. Program the key.
4. Remove the lock.
5. Cut the key.
6. Reinstall the lock.

Below are photos of the process.

A common issue encountered when coding 8A keys for PSA Smart vehicles: the keyless system (Keyless Entry) not activating after programming usingAUTEL MaxiIM IM508/IM608or other programmers.
The root cause often lies in differences within the key’s EEPROM data.

In this guide, we’ll walk through how to identify and solve this problem.

Guide:

Access the Programmer Menu
Start by entering the programmer menu on your Autel device.

Navigate to Transponder Section
Go to the transponder menu and select "Transponder Reading.” Use the automatic detection feature to read the key. Ensure the key is placed inside the device.

Read the Key Data
The device will read the key and display its ID, key type etc. Then, enter the "Edit” section to read the EEPROM data stored inside the key.

Analyze the EEPROM
Checkdata line 160.Focus on the first two bytes(first two numbers).

If the value is 01, the key is Type 2.

For the key to function properly, the original key must read 01. This ensures healthy operation of the keyless system.

Real-World Example: Opel Combo 2023

Let’s consider an example using an Opel key (for a 2023 Opel Combo). When reading this key, the data starts withC6. If you were to try programming another remote with this configuration, the remote would not work and would essentially become locked or non-responsive.

Why? Because the PSA system expects specific EEPROM values. A mismatch – such as seeing a different header instead of the required 01 – prevents the keyless entry from engaging.

The Solution

To solve this issue, you must ensure that the key’s EEPROM data matches the required Type 2 standard (starting with 01). If the key shows a different value (like C6), it will need to be reprogrammed or replaced with a compatible unit. Always verify the first two bytes of the EEPROM before finalizing the coding process.

Conclusion

Keyless entry failures after coding PSA Smart keys are often due to hidden EEPROM differences. By using an Autel programmer to inspect the first two bytes of the EEPROM, you can quickly determine if the key is compatible. Remember: 01 = Type 2 = functional keyless entry. Anything else, like a C6 header, will lead to failure.
