2012 Silverado Texas edition programed 3 fobs with remote start. 1 that came with this and 2 more I got on Amazon for $20. Everything works even the remote start but truck already had remote start feature already installed. Did it in my driveway in under 2 minutes. Saved time and money from having to go to the dealer that wanted almost $200 for a fob and $65 to program it.
