The Autel MaxiIM KM100 key programmer offers impressive functionality for all keys lost situations. This guide outlines a successful all keys lost programming procedure using the KM100 on a 2020 Toyota Corolla. This process also applies to 2019-2022 models.
Preparing for the Procedure
Before starting, obtain the 12-digit rolling codes for the vehicle. These codes are necessary for the immobilizer reset and can be acquired from a third-party provider like NASTF. Also, ensure your Autel KM100 is charged and updated to the latest software version. Having a stable internet connection is also recommended.
Connecting to the Vehicle and Initiating Programming
-
Turn the ignition to the unlocked position. Confirm the passenger door lock is functioning.
-
Connect the PLC200 dongle to the vehicle’s OBD-II port.
-
Pair the PLC200 dongle with the Autel KM100 via Bluetooth. This connection allows the KM100 to communicate with the vehicle’s immobilizer system.
Accessing IMMO Functions and Vehicle Identification
-
Navigate to the IMMO function on the KM100 and select Toyota.
-
Perform an auto VIN scan. The KM100 quickly decodes the VIN and displays the vehicle information, confirming the year and model.
Immobilizer Reset: All Keys Lost Procedure
-
Perform an IMMO status scan. While the original example had a DTC, it’s noted that DTCs aren’t typically present during key programming. If a DTC is found, you can attempt to erase it, but it’s not usually required.
-
Select Immo Learning – Immobilizer – Immobilizer Reset (all keys lost). This function prepares the vehicle to accept new keys.
-
Ensure the driver’s door is open as instructed by the KM100 prompts.
-
Enter the 12-digit rolling code obtained earlier. Accuracy is crucial in this step.
-
Confirm the code and initiate the immobilizer reset. The process takes approximately 16 minutes. Follow the on-screen prompts, which typically involve turning the ignition off, removing the key, and then turning the ignition back on.
-
The KM100 will display a 16-minute countdown timer. Do not interrupt this process.
Key and Remote Programming
-
After the immobilizer reset, proceed to add a new key. The KM100 will guide you through the steps, which include turning the ignition on with a master key (if applicable), entering a password, and cycling the key on and off. Since this is an all keys lost scenario, the KM100 will simulate the master key function.
-
Program the remote by following the on-screen instructions. This typically involves pressing specific button combinations on the new key fob.
Conclusion
The Autel KM100 provides a streamlined solution for all keys lost programming on 2019-2022 Toyota Corolla vehicles. By following the outlined steps and utilizing the KM100’s intuitive interface, technicians can efficiently program new keys and remotes, saving time and providing a valuable service to customers. The KM100’s affordability and ease of use make it a compelling alternative to more complex and expensive key programming tools.
