My truck went into lockdown when I changed my keys which in the column I couldn’t start my truck had to take it to the Chevy garage for them to reprogram my truck do you think maybe the shop guy just didn’t turn it on because he reset a lot of things he said wasn’t working to let me know

The P0650 code typically indicates an issue with the malfunction indicator lamp (MIL) control circuit, which might suggest that the MIL is either malfunctioning or has lost connection. This code doesn’t usually trigger a "lockdown" or immobilize the vehicle, but it can be associated with various system resets or reprogramming, especially after a key replacement.
Given that your truck was taken to the Chevy shop for key reprogramming, it’s possible that the technician needed to reset or reprogram several modules to ensure everything communicates properly with the new keys. During this process, the P0650 code could have been triggered if certain systems weren’t powered on correctly or had communication errors. Sometimes, after reprogramming, technicians may need to recheck and turn on any previously reset components to clear out any lingering error codes.
If the code persists after reprogramming, here are a few things to check:
- Inspect the MIL Wiring: Ensure there are no loose or damaged wires in the MIL control circuit.
- Re-run Diagnostic Scan: Sometimes, codes can linger temporarily after reprogramming, so re-running a scan can verify if it’s still active.
- Battery and Connections: Check the battery and all relevant connections, as voltage drops or weak connections can trigger similar codes.
