To reset it, you need to stick the key in, turn it to start,hold it there for about 1 second, let the key sit in the ON position for 10 minutes, the security light will start to blink. Turn the key back to OFF, and then turn it and it should start right up.
If not try it with your other key, if that don’t work, it will need to get towed to the dealer to get the keys reprogrammed to the computer.
