CGDI K2 Honda Activa Motorcycle Password Calculation
If you work with two-wheelers, you know that losing all keys for a modern Honda Activa BS6 equipped with a smart key system can be a major headache. Previously, you needed a dedicated, expensive tool just to read the password from the ECU. Now, thanks to a new update for the CGDI K2 key tool, you can do it all with one device.
In this guide, we’ll walk you through how to read the password from the Activa’s ECM and prepare to learn a new smart key—even when all original keys are lost.
What You’ll Need
-
Honda Activa BS6 (latest model with smart key system)
-
CG-branded smart key (generated/programmed blank)
-
renew cable for K2
Step 1: Connect the CGDI K2 to the Activa’s ECM
Before starting, ensure the CGDI K2 is powered on and properly connected to the Honda Activa’s ECM (Engine Control Module) using the correct cable harness. This allows the device to communicate directly with the immobilizer system and read the necessary security data.
Step 2: Navigate to the Honda Activa Motorcycle Password Calculation
Once the CGDI K2 is connected and powered:
-
Go to “More Functions” on the main menu.
-
Select “Honda Activa Motorcycle Password Calculation” – this option appears thanks to the latest update specifically for the Activa smart key system.
- Check wiring diagram
- Connect the renew cable to the ECM module according to the diagram.
Step 3: Read and Save the Data
With the connection verified:
-
Click on “Read Data.”
-
The CGDI K2 will begin reading the vehicle’s ECU data.
-
Once the reading is complete, the full data set will appear on the screen.
Important: Save this data immediately by clicking “Save” and then “Continue.” The device will confirm that the data has been saved successfully.
Step 4: Retrieve the Password
After saving the data:
-
Go to the “History” section on the CGDI K2.
-
The calculated password will be displayed.
This password is critical. It allows you to perform key learning (programming) on the vehicle, even if all original keys are lost.
Step 5: Prepare for Key Learning
Now that you have the password:
-
Use the CGDI K2 to generate a smart key (if you haven’t already). The transcript notes that the CG-branded smart key was generated entirely using the CGDI K2.
-
Take the device and the generated key to the vehicle.
-
With the password and proper connections, you can now perform direct key learning on the Activa.
Why This Update Matters
Previously, working with Honda Activa BS6 smart key systems—especially in all keys lost situations—required a separate, specialized tool just to read the ECU password. That meant extra cost and more equipment to carry around.
With the CGDI K2 update, you can now:
-
Read the password directly
-
Generate a new smart key
-
Learn the key to the vehicle
…all using a single device.
Conclusion
The new Honda Activa BS6 smart key functionality on the CGDI K2 is a game-changer for automotive locksmiths and scooter repair shops. Whether you need to add an extra key or recover from an all keys lost scenario, the CGDI K2 now provides a complete, affordable, and efficient solution.

How to Solve Autel IM508 2021 Jeep Programming BOOT2 Error
Problem:
Tried to add a spare key to a 2021 Jeep Compass with Autel IM508.
This is what I am getting, trying to read password it keeps.
Error: Programming BOOT2
Any solution?
Solution:
Voltage is low.
Connect battery booster or change battery.
Battery is dead on that car, get a battery maintainer as at 9V no modules will talk and you risk damaging the car. For any sort of programing 13.5V is a must.
If you use correct booster, you can set to 13.5V or more.
Feedback:
The car had a problem, electrical problem. The battery was good, but the voltage was showing low. I ended up figuring it out and got the job done. I had noticed the voltage but when I hook up to the battery, it will show 12.5 but on the scanner, it shows 8.
