Key Programming for a 2019 Hyundai Tucson Using the Autel MaxiIM IM508S

The Autel IM508S is an advanced key programming tool suited for tasks such as key generation, backup, and repair of anti-theft data. Here, we’ll walk through the process of programming a new key for a 2019 Hyundai Tucson after all original keys are lost, focusing on reading the password and learning the new key.

Preparation:

Ensure you have all necessary tools and the vehicle is securely positioned. The IM508S communicates through the OBD2 main cable connected to the vehicle.

Step 1: Reading the Immobilizer Password

1. Initiate Communication:
   • Turn the ignition on and start the vehicle.
   • Access the IMMO function on the IM508S.
   • Select ‘Hyundai’ as the car brand and click on ‘Auto Select’.
   • Confirm the vehicle identification number.
   • Choose ‘USA’, then confirm with ‘Yes’.
   • Select ‘Smart key’, then ‘Hot function’, and finally ‘Read immobilizer password’.
   • This is applicable only for models with an 8A chip smart card.
2. Process Execution:
   • Click ‘Yes’ to proceed.
   • Turn on the hazard warning lights.
   • Turn the ignition off.
   • Open and close the driver’s door once.
   • Allow the IM508S to read the password. This might take some time, so patience is required.

Step 2: Learning the Smart Key

1. Start the Learning Process:
   • Click on ‘Smart Key Learning (Guide)’ and then ‘Start’.
   • This function supports adding new keys or replacing all lost keys. Note: All old keys will be cleared from the system and must be relearned.
2. Key Programming:
   • Confirm by pressing ‘Yes’ to continue.
   • Turn the ignition off (ensure the instrument screen is off).
   • Open and close the driver’s door once.
   • Enter the 6-digit security password obtained from the first step.
3. Activating the Key:
   • Click ‘OK’ to proceed.
   • Within 5 seconds after pressing ‘OK’, use the back or top of the smart key to press and hold the START button for 5 seconds until the anti-theft light flashes.
   • If the operation fails, remove the key case and retry the activation steps to ensure the key chip is programmed correctly.
4. Finalizing Programming:
   • Press ‘Yes’ to program additional keys or ‘No’ to finish.
   • Exit the system back to the vehicle selection menu to confirm successful programming.
5. Testing:
