Here obdii365.com introduces 3 ways to program Volkswagen Golf or Polo (2010-2014) all keys lost using Autel IM508S/IM608 key programmer.
- Way 1: Service Mode All Keys Lost
- Way 2: All keys lost via EEPROM
- Way 3: All Keys lost with godiag test platform on bench
When a method fails, switch to an alternative solution.
Way 1: Service Mode All Keys Lost
Step-by-Step Procedure
1. Remove the Instrument Cluster
- The immobilizer data is stored in the instrument cluster, so it must be removed from the dashboard.
- Disconnect the wiring harness carefully to avoid damage.
2. Read the EEPROM Data
Extract the PIN code and CS code from eeprom data, which are essential for key programming.
Menu Path (in IM508S)
- Manual Selection → Europe → VW Polo (2010-2014)
- Select Control Unit-Immobilizer- Continental CAN Ins NEC+ 24C32 Immobilizer
- Select Enter Service Mode with All Keys Lost (G-box) (this powers up the cluster for communication)
- Follow the wiring diagram to connect Gbox with cluster. Connect the DB16 cable to the instrument cluster.
Connect the IM508S with the OBDII femail connector of the G-box and connect a 12V power supply yo the DC12V terminal of the G-box - The tool will display the cluster type (e.g., Four Motors Speaker – Version 1).
- Confirm and proceed to read the EEPROM data.
3. Extract PIN and CS Code
- Once the EEPROM is read, the tool will display:
- PIN code (required for key programming)
- CS code (security authentication)
- Used/free key slots (e.g., Slot 1 & 2 used, others empty)
4. Generate a Dealer Key
- Select Make dealer key function.
- Insert a blank key into the programmer.
- Enter the CS code (extracted from the EEPROM dump) in the following format:
- The tool will confirm “Dealer key generated successfully.”
5. Reinstall the Instrument Cluster & Learn the Key
- Reconnect the instrument cluster to the vehicle.
- Turn the ignition ON with the new key.
- The immobilizer should recognize the key automatically (if not, use the IM508 to manually “learn” the key).
Way 2: All Keys Lost via EEPROM
Remove and disassemble instrument cluster.
Locate chip 24c32. Connect chip with xp400 pro via eeprom clip adapter.
Select cluster type NEC 24C32
Select All Keys Lost (via Dump)
Follow steps below to complete key programming:
Backup ABS code
Read EEPROM via Programmer
Write EEPROM via Programmer
Write EEPROM via OBD
Read IMMO Data
Make Dealer Key
KEY Learning
Recover ABS Code
Way 3: All Keys Lost with Godiag GT110 Test Platform
his guide walks through bench key learning, a method where you program a key using just the instrument cluster and a IM508S/IM608.
Step-by-Step Bench Key Programming
1. Set Up the GoDiag GT110 Simulator
- Connect the GoDiag GT110 to the instrument cluster (from a VW Polo 2009-2014).
- Plug in the 12V power supply to simulate the car’s electrical system.
- Use the DB15 cable to link the GoDiag to your IM508 tablet/PC.
2. Power On the Instrument Cluster
- Press the red ignition button on the GoDiag—this will light up the dashboard (simulating “key on”).
- The cluster should now be in diagnostic mode, ready for programming.
3. Connect the Autel IM508S
- Launch the Autel tool and select:
- Manual Selection → Europe → VW Polo (2010-2014).
- Choose Control Unit → Immobilizer.
- Select NEC24C32 (the immobilizer type).
4. Enter PIN & CS Code
- If you have the PIN and CS code (extracted from the cluster’s EEPROM), enter them now.
- If not, you may need to read the EEPROM first.
5. Insert & Program the Transponder Chip
- Place the blank transponder chip into the GoDiag’s key slot.
- Select “Key Learning” in the Autel IM508S.
- The system will program the chip within 30 seconds.
6. Verify the Key
- Once programmed, the Autel will confirm “Key Learning Completed.”
- The new key should now start the car (once the cluster is reinstalled).
