This is about one of my other cars, a 2012 Chevy Tahoe LT 4X4, so today I was going to drive it and when I put the key in the ignition it was giving me a hard time going in, like something isn't fitting in there right, it resists when I try to pull it out as well, the key is still functional and starts the car fine, the spare set which has never been used once works perfectly fine. nothing looks off or unusual with the key, does anyone know what this could be?
