Gm key relearn procedure video, YouTube
try this procedure in video.I wonder if you missed a step in the process? Did all the remotes get paired to the vehicle during the process? That’s a must. Congrats on the new motor. What was the nail in the coffin for the motor?
See if there’s something you may have passed over in the clip. Don’t mind the video of the Yukon, it’s the same procedure as the Escalade just a different key fob & orientation of the DIC buttons.
