I purchased a 2nd key fob for my 2017 Chevy Cruze push start and when I trying to program the new fob doesn't work. I only have the one fob and I purchased the exact same style, look, and even the same FCC#. I am able to reprogram my old fob and the system thinks I have 2 working fobs (it let's me out of program mode and doesn't ask me to program #2) but the new fob will not work. Any idea why? And yes, I do have a new battery in the new fob.

 

My 15' Malibu will usually work by setting it to start, then remove old key, and turning to on for a few seconds. If that doesn't work, and did not, the last lime insert the Fob to on for 10 or 11 minutes and repeat two more times. should be 35 to 40 minutes in total, as the indicator light goes out every time. Your new FOB should work after that.
