Anti-theft . the car I'm working on is a 2005 chevy uplander it was stolen with along with the keys. The owner purchased new keys and I went through the learn process. The car will crank hit not start the dash said start disabled . my question is did I miss something in the process I relearn the keys but I still get the code b2960.

Sorry, but yes looks like it. Did you relearn the key or just the fob?
