What Does OBP Mean in Digimaster 3 Support List?

 Question: I’m looking at the Digimaster3 support list. What do "Soldering Contacts" and "Memory Directly" mean in the image? "Soldering Contacts" refers to soldering after removing the dashboard; while "Memory Directly" refers to connecting to the vehicle’s OBD interface?

Answer:

The OBP here does not mean connecting to the vehicle’s OBD. Both the "Soldering Contacts" and "Memory Directly" methods mentioned above require removing the vehicle’s dashboard. The difference lies in the connection method:

As shown in the image below, "Soldering Contacts" involves soldering the wires to the circuit board contacts.

As shown in the image below, "Memory Directly" involves desoldering the chip and then reconnecting it to the Yanhua OBP adapter.

How to Add 2025 Buick GL8 Smart Key with KEYDIY KD-X4 & DOIP Adapter?

This guide provides a straightforward walkthrough for programming a new 2025 Buick GL8 smart key using the KEYDIY KD-X4 and the Specialized DOIP Adapter. This process is essential for newer Buick models that utilize rolling code security.

Prerequisites & Tools Needed

Before starting, ensure you have the following hardware ready:

• KD-X4 Key Programmer
• KD Universal Smart Key
• KEYDIY DoIP Adapter
• Stable internet connection (for third-party password calculation)

Step-by-Step Programming Guide

Key Identification & Generation

First, verify the frequency of the original key to ensure the new KD smart key is programmed correctly.

• Test the original key’s frequency (it should be 433.92 MHz).
• Power on the KD-X4 and select Remote Function > Smart Key Remote. > Buick > GL8 2025-ID4A 433.92.
• Place the new KD smart key into the KD-X4 slot and generate the remote.

Hardware Connection

Newer Buick GL8 models require the DOIP protocol for IMMO programming.

• Disconnect the standard OBD plug and connect the DOIP Adapter.
• Plug the adapter into the vehicle’s OBDII port.

IMMO Programming & Password Calculation

Since the 2025 Buick GL8 uses a sophisticated rolling code system, static passwords will not work. You must perform an online calculation:

• In the KD app, navigate to IMMO Programming > KD-X4 > DOIP > Start Execution > Add Smart Key.
• Follow the prompts to press the start/stop button once, turn off the ignition and move all existing keys away from the sensing area.
• Rolling Code Entry: The device will generate data. Send this data to your third-party provider to receive the first password.
• Repeat the process for the second set of data to get the second password.

1. Final Matching

• Once the passwords are confirmed, wait 5 seconds.
• Place the new KD smart key into the square key slot next to the cigarette lighter.
• Press and hold the Start/Stop button for 5 seconds to finalize the link.

Testing the Results

After the app confirms "Matching Completed," test all remote functions:

• Unlock/Lock: Ensure the doors respond immediately.
• Sliding Doors: Verify the electronic sliding door buttons function correctly.
• Engine Start: Ensure the vehicle starts with the new key while the original is kept at a distance.
