Add 2020 Toyota Tacoma XM38 Smart Key with VVDI Key Tool Plus

 This guide walks through the steps of programming an Xhorse smart key to a 2020 Toyota Tacoma using the Xhorse Key Tool Plus and the XM38 Smart Key, starting with one already working key.

Tools You’ll Need

Xhorse VVDI Key Tool Plus (with internet connection)

Xhorse XM38 Smart Key (or compatible Xhorse smart key)

One existing working key for the Tacoma

Step-by-Step Programming Process

1. Identify the Key Type
Begin by determining the transponder type of the original key.

On the Key Tool Plus, navigate to Transponder Clone.

Insert the original key and select Read.

Note the type displayed—in this case, Type A8. This is essential for key generation.

2. Generate the New Smart Key

Return to the main menu and go to Remote Program > Asia > Toyota > Tacoma.

Confirm the key type matches (A8).

Place the blank Xhorse smart key on the tool’s programming area.

Select Generate.
Note: An active internet connection is required for this step.

Once completed, confirm and return to the main menu.

3. Enter IMMO Programming Mode

Select IMMO Programming > Asia > Toyota> Select by area.

Choose Toyota Tacoma, then select Keyless Go and 2110 PCB.

Start the programming process and choose Add Smart Keys.

Follow the prompt to switch the ignition ON using the existing working key.

4. Register the Existing Key

The tool will show the number of registered keys and keys to be added.

When prompted, touch the ignition switch with the original registered key.

A beep will confirm the key has been recognized.

5. Register the New Xhorse Key

Within 30 seconds, touch the ignition switch with the new Xhorse smart key.

Hold it in place until the tool indicates “Key registration succeeded.”

The system will confirm when matching is complete.

6. Test Both Keys

Turn the ignition OFF and test the original key to ensure it still works.

Then test the newly programmed Xhorse XM38 smart key—it should start the vehicle.

For final verification, remove the original key from the cabin and confirm the new key operates independently.

Delphi MT62.1 ECU Pinout to Xhorse VVDI Prog

Main Improvements	–	1. Improved stability &consistency 2. Optimized PCF7935 performance 3. Added VW 4A/49 support	1. Latest ID5C support 2. MQB platform compatible 3. Rewritable & reusable
Best For	Users focusing on legacy & common vehicle models	Most professional locksmiths (seeking balance of cost & proven performance)	Advanced users & shops dealing with newer/high-end vehicles
Cost Efficiency	Cost-effective for supported protocols	Excellent (optimal balance of features and reliability)	Higher initial cost, but reusable for long-term efficiency

XT27A: The Foundational Multi-Protocol Chip

The XT27A established the series, providing broad support for common protocols including PCF7930-7939, ID46, ID48, 4C, and 8A/8H for Toyota and Hyundai models. It serves as a capable and economical solution for many standard cloning and programming tasks.

Typical Use Case: A practical choice for users whose work primarily involves older or commonly encountered vehicle models, where its protocol coverage meets most requirements.

XT27B: The Reliable Daily Performer

The XT27B builds upon the XT27A’s foundation with enhanced stability and added protocol support, including ID49 and 4A (important for Volkswagen applications). Its optimized handling of chips like the PCF7935 improves success rates in cloning operations.

Pros: Demonstrated reliability, expanded Volkswagen support, consistent performance across a wide vehicle range

Ideal User: Professional locksmiths and technicians seeking a dependable, well-rounded chip for the majority of everyday jobs

XT57B: The Advanced Future-Proof Solution

The XT57B represents the premium offering, introducing support for newer protocols such as ID4A and ID5C, along with specific MQB-platform ID48 compatibility. Its defining feature is rewritability, allowing the chip to be erased and reused multiple times within defined limits.
