So today I tried to start my car and got a "no key detected" I finally got my car started by holding my key by the engine start button so I took my car to the dealership to get the battery replaced. After the battery replacement, everything worked fine for about 30 mins then the same problem occurred again. Is it the battery again? Has anyone had this problem before to learn it was something else. Any advice would be much appreciated

 

UPDATE: key is now working again now that im home, apparently the only time its not working is when im at work which is on a military base. maybe they were running EMI drills. who knows

 

Had the same issue near a cell tower. Had to use the metal key to get into the car too.
