empty key data for 2021 Chevy Silverado 2500

Question

after viewing the instructional youtube video from "MPC | How to use your Flashlink Lite C" and following the instructions correctly, I keep ending up with "EMPTY KEY DATA" with the following error message: "The module was not able the vehicles immobilizer data. Reconnect the module to the vehicle and follow the instructions from STEP 1 to sample the immobilizer data" however in the youtube video, the module is not connected to a vehicle only a PC. Please help.

Answer 1

Empty key data typically happens when the module was not first progammed to the vehicle. Once that is done, you disconnect it from the car to run the dcryptor process on the flash link.
