Select Yes to continue. This function supports both add-key and all-keys-lost procedures. Existing keys will be erased and must be relearned if required.

Follow the IM608 Pro2 prompts:

1. Turn on the hazard warning lights.
2. Turn the ignition off.
3. Open and close the driver door once.

PIN Entry and Key Programming

1. Enter the PIN code when prompted.
2. After the PIN is accepted, press OK. Place the smart key near the Start/Stop button and press the button with the key.
3. When the tool displays Programming succeeded, select Yes to add another key.
4. Repeat the same process for the second key. When finished, select No to complete the programming.

Key Function Check
Check the programmed keys. Make sure the vehicle recognizes both keys.

Verification
The vehicle starts normally with the programmed keys, and the basic smart key functions operate correctly.

Check the Key and Start the Job

The replacement key had a hatch button, while the factory key had a trunk button, so the button configuration was checked before programming. The vehicle already showed two smart keys registered, but the job was to add the replacement key.

Access the Honda Keyless System

1. Connect the Autel IM608 II and select Automatic Selection → Smart Key → Push to Start → Yes → Control Unit → Keyless System (Honda).
2. When prompted, confirm that the ignition is turned on by pressing the Start button twice. Check Number of Smart Keys to see the registered-key count.
3. Select Add Key → Yes to begin the registration procedure.

Register the Replacement Key

1. After selecting Add Key → Yes, turn the ignition off as prompted. Remove the new key and leave the original working key in the vehicle.
2. Turn the ignition on and follow the vehicle condition check. When prompted All keys out, remove the key from the vehicle.
3. Bring the new key back into the vehicle. Turn the ignition off and back on as prompted. Confirm both the keyless access and immobilizer indicators are off; registration is complete.

Verification

Turn the ignition off and back on as prompted, then start the Pilot. The engine started normally, and the key’s basic functions worked, including the hatch button.

3. Start reading the key IDs.
   Place the original smart key (tag facing upward) on the ignition switch. Keep the key in contact with the switch and do not press any buttons.
   After the original key is detected, press OK and place the new smart key on the ignition switch to read its ID.

Program the New Smart Key

1. Select Start to Program Key.
   Place the original smart key on the ignition switch and press OK.
2. When Learning Success appears, continue with the new smart key. Remove the original key, place the new smart key on the ignition switch, and press OK.

Waveform Signal Is Distorted or Contains Noise

If unwanted signals are displayed or waveform signals are distorted:

• Use only the supplied test leads or probes to connect with the input channels.
• Check the test leads or probes for damage.
• Ensure the polarity of the test lead connections is correct.
• Make sure the signal and ground connections are clean and secure.
• Ensure the ground lead provides a direct ground connection from the circuit to the input channel.
• Keep test leads away from components or systems that may introduce unwanted noise, including:
  • Electric motors
  • Secondary ignition components
  • Relays
  • Alternators

Read the IMMO Password

From the KM100 menu, go to:
IMMO → MG → Manual Selection → MG5 → 2021–2022 → Smart Key → Yes → Control Unit → Keyless System (CAN) → Password Reading

1. Turn on the hazard lights to wake up the vehicle.
2. Turn the ignition ON when prompted.
3. Wait for the password to be read. In this case, the password is 7449.

Program the New Smart Key

1. Select Add Keys.
2. Place the key to be programmed in the key sensing area inside the center console box. Remove any other keys from the vehicle, then switch the ignition ON.
3. Press Continue → Start. Wait until the Autel KM100 reports Key Programming Success.

Verification

Confirm the vehicle starts normally and the newly programmed smart key operates as expected.

Case Background
The customer supplied a used DSG Mechatronic from a different model year. Since Volkswagen transmission modules are not simple plug-and-play replacements, the first job was confirming the donor was actually suitable for cloning.

Before putting anything on the bench, I compared the original and donor modules and confirmed they shared the same part number. Once that checked out, it was safe to move on with the cloning procedure.

Step 1: Set Up the Original TCM
Start with the original Mechatronic because it contains the vehicle-specific data.

1. Connect the original TCM to the Autel IM608 Pro2 through the DB15 cable and G-BOX3.
2. Select the correct DSG transmission type.
3. Verify the bench wiring and power supply before reading the module.

Stable power is important during bench work. Any interruption while reading or writing module data can cause unnecessary problems.

Step 2: Read the Original TCM Data
The original TCM is the clone source, so save all required data before touching the donor module.

1. Read the Flash data.
2. Read the Internal EEPROM.
3. Read the External EEPROM.

Save each file with a clear name. Keeping the original files organized makes the writing process much safer later.

Step 3: Backup the Donor TCM
Before writing any data, back up the replacement module.

1. Connect the donor Mechatronic using the same bench setup.
2. Read the Flash, Internal EEPROM, and External EEPROM.
3. Save the donor files separately from the original backup.

This backup gives you a recovery option if the donor module ever needs to be restored.

Step 4: Write the Original Data to the Donor Module
Once both modules have been read, write the original vehicle data into the donor Mechatronic.

1. Write the original Flash file.
2. Write the original Internal EEPROM.
3. Write the original External EEPROM.

Wait for each operation to complete before moving to the next file, and confirm each write finishes successfully.

Step 5: Install and Verify
Reinstall the cloned Mechatronic and perform a quick diagnostic check.

1. Run a full scan with the Autel IM608 Pro2.
2. Confirm there are no TCM or immobilizer fault codes.
3. Start the engine and verify the vehicle operates normally.

In this case, the vehicle started without issues and no related fault codes were present after installation.

Workshop Notes
The biggest takeaway from this job is to verify the donor module before spending time on the bench. Matching the part number is far more important than simply matching the vehicle model or year.

When cloning Volkswagen DSG Mechatronics, always read and save the original TCM data first, then back up the donor module before writing anything. A simple file naming system for the Flash and EEPROM backups also helps avoid writing the wrong files during the cloning process.

On BMW 4 Series (2013/02–2021/05), key addition was attempted using Autel IM608 II, both on bench and on vehicle.

After reading, modifying, and writing back the EEPROM data, the following error appeared during Immobilizer Status Scan → Add Key:

“Note: The ‘Key Learning’ function is not supported for the current ECU. A possible reason is that programming has not been performed.

If you are sure programming has been performed successfully, please feed back the version information in time.”

The issue was caused by incorrect operation steps. The correct procedure is to restore the original EEPROM first, then perform ECU Repair before continuing key learning.

Solution

1. Restore original EEPROM Data

System Selection → Immobilizer → FEM/BDC Immobilizer → EEPROM Operation → Chip Type → Write Operation
Write back the original EEPROM data that was previously read.

2. Perform ECU Repair

System Selection → Immobilizer → FEM/BDC Immobilizer → Programming Operation → ECU Repair

3. Continue key learning (FEM workflow)

If directly making a key from the immobilizer scan, after scanning select BDC/FEM Key Learning (Read ECU) to proceed.
For FEM vehicles, FEM does not support OBD preprocessing.

Final Result

The issue was successfully solved. The error message no longer appears, and key programming can now be performed normally using Autel IM608 Pro2.
