Q: Battery or alternator

asked by on December 15, 2016

So the battery saver came on yesterday. And I understand that is an issue. Now my car won't start at all in fact my keys are currently stuck in the ignition. I also know this is going to cost money. But realistically I am going to have replace my alternator or battery? Or can I just recharge my battery this is the first time this have ever happened to my car. I am nervous about how much this could cost me. I also do realize that something will have to be replaced in order for my car to actually work.

My car has 993600 miles.
My car has an automatic transmission.
