OBDSTAR X300 Classic G3 can support all keys lost and new key adding for VW MQB48-5A type dashboard. Here take a 2018 Volkswagen Tiguan MQB48-5A as an example to show the all keys lost programming operation guide.
To perform this task, the following accessories are necessary to work with OBDSTAR G3:
OBDSTAR RH850/V850 Adapter Full Kit
- C4-06 Adapter
- C4-06 C02 Decryption Board
- ELV Data Collector- MQB Collector
- ECM Dedicated Cable (ECM-001)
- TCM Dedicated Cable (TCM-Kit1)
These tools facilitate efficient data collection from the vehicle’s modules.
Main steps:
Step 1: Read IMMO Module Data
1.Read Dashboard IMMO Data
- Read ECM IMMO Data
- Read TCM IMMO Data
- Read ELV IMMO Data
Step 2: Calculate Synchronization Code
Step 3: Make Dealer Key
Step 4: Program Keys
Step 5: Check IMMO State
Before performing the related process, need to identify the vehicle info first.
Connect the X300 Classic G3 key programmer to the vehicle’s OBD port.
Navigate to:
IMMO-> VW/AUDI/SKODA/SEAT-> VW/AUDI/SKODA/SEAT V45.48
Two options are available:
- MANUAL SELECT MODEL
- MANUAL SELECT SYSTEM
Select MANUAL SELECT SYSTEM-> VW-> MQB METER
If connected to the vehicle via OBD, the system can directly identify whether it is type 5A or 5C.
Select [MQB48-5A/MQB49-5C Detect] option, then press the ignition to power on the dashboard
Identify the system is a 5A type.
Next, select [All keys lost]
This function requires an internet connection. Ensure the network connection is normal, and then tap “OK” to continue
Step 1: Read IMMO Module Data
Since this is a proximity key system, IMMO data must be collected from four modules:
- Dashboard
- ECM (Engine Control Module)
- TCM (Transmission Control Module)
- ELV (Electric Steering Lock)
1.Read Dashboard IMMO Data
Disassemble the dashboard to access the R7F70147 MCU.
Follow the wiring diagram to solder the decryption wires to the dashboard’s PCB, use the C4-06 C02 decryption board and ensure no shortcuts are made.
Connect the OBDSTAR MP001 Programmer and read the dashboard’s flash and EEPROM data.
Parse the Data: The system will extract the CS code for the dashboard.
- Read ECM IMMO Data
Identify the ECM Model: MED 17.5.25
Use the ECM-001 dedicated cable (or jumper wires) to connect.
Read EPROM & Flash data, then parse to obtain the CS code.
- Read TCM IMMO Data
Identify the TCM Model: DQ380DE.
Connect the OBDSTAR P004 Adapter (DQ380 Cable) for the connection.
The system will read the data and generate the TCM IMMO data file.
- Read ELV IMMO Data
Method 1: Read IMMO Data by RH850/V850 Adapter
If you do not have the ELV data collector, you can choose method 1 to read IMMO data by RH850/V850 Adapter, and requires you to read data by soldering wires.
Method 2: Collect ELV Authentication Data and Calculate IMMO Data
If you have the collector cable, just connect it directly to the OBD port, and then plug in the dashboard connector. Once everything is complete, you can start collecting the ELV authentication data.
Here we use the method 2 to operate.
Connect the ELV Data Collector: Plug it into the OBD port and connect the dashboard connector.
Collect Authentication Data: The ELV IMMO data is calculated directly through the server.
! Important Note:
If any module (Dashboard, ECM, TCM, or ELV) is non-original (replaced without dealer programming or IMMO OFF), the system will not calculate ELV IMMO data.
Step 2: Calculate Synchronization Code
Load the collected Dashboard, ECM, TCM, and ELV IMMO data.
The system calculates the synchronization code (starting with the VIN).
Verify all data before proceeding.
Step 3: Make Dealer Key
Load the dashboard IMMO data and synchronization data into the system.
Place the blank key into the key sensing coil and select Make Dealer Key.
The vehicle will recognize the key upon completion.
Step 4: Program Keys
Reconnect the main cable of X300 Classic G3 to the OBD port.
Select Program Keys and load the dashboard IMMO data.
Place the key near the induction coil and press the ignition.
The dashboard will display a change in key status change (e.g., 0 to 1), confirming successful programming.
Step 5: Check IMMO State
Turn on the ignition and check:
- Number of keys presented value
- Dealer Key Status
- Locked Key Status
- Learned Key Status
Finally, test the remote functions (lock/unlock) to ensure full operation.
That’s the whole process to do all keys lost key programming for the 2018 Volkswagen Tiguan MQB48-5A by OBDSTAR X300 Classic G3 Key Programmer successfully.
