My Mazda 6 2015 model was showing blinking rapidly and wont start the engine. The car gets power but won't start engine initially thought battery issue jumped and used battery from AAA service guy still didn't work, replaced key fob batteries still didn't change anything got the car towed to the dealer. the service guy says it won't let him connect his laptop need more hours of diagnostics. anyone faced this scenario or have any suggestions that might help?

 

Leave it with the experts.
