Today I’m going to show how to unlock or renew a Nissan smart key with Autel MaxiIM KM100 Immo Key Programmer. This key has been used on another vehicle and locked. By unlocking the key can make it be reprogrammed to a new car.


Let’s read the key info first.

As we can see, the key status is locked now.
