Having this issue right now. Got into the van last night with my Son and put the key in like always and nothing. Tried a bunch of different things and even had my wife take us home and got the back-up key thinking that the sensor wasn't working in the key. In the end I had to get towed and taking it to the shop today. So anyone have an updated answer? NV 2500 2012 model with around 35,000 miles(still new). Thanks for any ideas!
