Issues with car starting/not recognizing 2 key fobs.

Hello, this is abnormal, but it could be due to some fault with battery voltage - make sure the battery is fully charged and able to sustain a full load. It could also be due to a transceiver issue for the fobs. It could be due to the fobs needing programmed - but I can't imagine why they would have lost programming. Is there any other missing pieces to this story? Damage? Accident? Repairs? Something you haven't shared yet? Sure seems random that it just doesn't work anymore suddenly. Share more information.
