This is a 2020 Chevrolet Silverado with blade key. Here you can add key but the guy said that he wants to erase all the keys, so we are gonna go to all keys lost procedure.
You can add key even if you don’t have a working key on chevy, Adding a key doesn’t delete current keys programmed to the vehicle.
** NOTE:
1.Make sure battery fully charged, this is highly recommended, if battery isn’t fully charged there is a possibility that vehicle won’t start.
2.If it is smart proximity, IM608 won’t calculate security code directly. This is blade key, so it will calculate pin.
