How to Clone Toyota, Lexus &Subaru 4D/8A Transponders with Autel KM100 and AT100

Losing your only working smart key can quickly turn into a stressful situation, especially when you need access to your vehicle in an emergency. For supported Toyota, Lexus, and Subaru models, the Autel MaxiIM KM100 paired with the Autel AT100 Super Transponder provides a convenient solution for smart key immobilizer (IMMO) cloning.

With the AT100, you can clone a supported smart key transponder when a working spare or emergency key is needed. The process is designed to transfer the necessary transponder information from the original key to a compatible AT100 transponder.

The AT100 supports smart key IMMO cloning for selected Toyota, Lexus, and Subaru applications, including the following transponder series:

How to Clone a Toyota, Lexus or Subaru 4D/8A Smart Key Transponder

Using the Autel KM100 and AT100 Super Transponder to read the original key and transfer the compatible IMMO data to the new transponder, technicians can complete the cloning process in a few simple steps.

Step 1: Connect the KM100 to the Internet

Make sure the KM100 has a stable network connection before starting the key cloning procedure. A network connection helps ensure that the device can access the required application and key-related functions.

Step 2: Open the “Reading/Cloning” Function

From the KM100 home screen, enter the “Reading/Cloning” application to begin the transponder identification and cloning process.

Step 3: Read the Original Key

Place the original smart key on the designated coil area of the device, then select “Reading”. The KM100 will identify and read the transponder information contained in the original key.

Step 4: Start the Cloning Process

Once the reading process has been completed successfully, select “Clone” and then choose “Start” to begin preparing the data for the compatible replacement transponder.

Step 5: Place the AT100 Super Transponder

Remove the original key from the coil area and place the AT100 Super Transponder in the designated position. Select “Next” and allow the KM100 to complete the cloning process.

Step 6: Prepare the Cloned Transponder for Emergency Use

After the cloning process is completed successfully, the AT100 transponder can be used as the cloned IMMO transponder for supported applications, providing an emergency key solution when an additional working key is needed.

Why Use KM100 with the AT100?

The KM100 is a versatile automotive key programming tool, while the AT100 adds dedicated transponder cloning capability for supported applications. Using the two together gives technicians a practical workflow for reading an original key and preparing a compatible cloned transponder.
