Hello, my name is Bobby. Thank you for the question. In some cases this will occur iof the battery is low. From what you are saying it seems like the battery should be fine but I would have it tested because the computer will shut down most of these systems when there is low voltage. If the battery is fine then most of the time this is either due to the key FOB not being picked up or most of the time it is the electronic ignition switch itself. The push button switch is a common failure and when this does not work then most of these fuses will not power up. I hope this helps. Please let me know if you need more help with this.
This is not a battery issue then. It sounds like a key fob issue. It can be a connection issue, but it sounds like the fob is not being recognized.
