2017+ GM Seed/Key

Modified on Thu, 26 Oct 2023 at 08:53 AM

All 2017+ GM vehicles use a seed/key process to unlock.

The first time you read the PCM, you will have to be connected to the Internet and using VCM Editor version 4.5 (or later).

If it doesn't unlock right away, wait at least 30 minutes and try again.
