The Smart Key Maker GH (often associated with Toyota/Lexus G and H chip systems) is a plug-and-play OBD2 device designed to program transponder and smart keys in approximately 20 seconds.
Programming Steps for Toyota G/H Chips
The device typically features a switch on the side: the right side is for adding remote controls, and the left side is for adding transponders.
1. Adding a Transponder Key
Preparation: Sit in the car, close all doors, and insert your existing main key into the ignition.
Connection: Turn the ignition ON and plug the Smart Key Maker into the OBD port.
Initialization: The device will beep twice. After 2–3 minutes, the anti-theft (SEC) light will stay on.
Key Swap: Remove the main key (the SEC light will flash). Insert the new key (do not turn it).
