Quattroporte Key

[Sym7]

I’m hoping someone can help me. About a month ago, my Quattroporte (2013) had a message saying battery in key fob was low. I replaced the battery. All fine for a week. And then a few days later sometimes the doors wouldn’t unlock or lock on first click. Earlier this week I had a message saying no key detected. I locked the car and unlocked it and all worked okay. Then yesterday, the car simply would not start. Absolutely nothing when I pushed the start button. I tried my spare key (same problem, although I think it became my spare because the battery was flat).

I put the main car battery on charge overnight and replaced both key batteries. I tried the car this morning but now I can’t even unlock the door with either key. Any ideas???
