This is 2021 Lexus NX300, I'm going to make a new key for this car with Autel MaxiIM KM100 Universal Key Generator by OBD.
Plug VCI 200 into OBD, connect to KM100.
IMMO >> Lexus >> Manual selection >> USA >> NX300 >> 2015-2021 >> Smart Key >> Yes >> Control Unit >> Keyless System(CAN) >> Number of smart keys
Turn on hazard warning lamps.
Number of keys: 1
Add smart key >> Turn on hazard warning lamps.
Notice:
Each step must be completed within the specified time.
The position for learning include: 6
Put a smart key to be learned close to the STAR button.
Learning succeed.
Go back to check the number of smart keys.
Now Autel KM100 tells it's total 2 keys.
Test the new key, it can work normally.
Done.
