Lots is issues Mazda

Hello in have a mazda 6 2006 v6 3.0L. 6 days a go the car was working fine I came home turned off the car and the next morning I came to the car I saw the hazard lights are on and the car is off I was still walking towards the car. I tried to open the door with the remote and it would not work I had to manually open by entering the key. Them I tried to start the car it would not start and the hazards lights are still on. I was getting late for work do I left it as it is when I came back from work it was the same thing. So I boosted the car and the car started ever since that day my remote won't work and the locks inside would not work and my flasher would not work. When I press the right or left flasher the hazard lights comes on and stay solid when I push the hazard light swith the hazard lights comes on and stay solid would not flash what is the issue?The hazards lights are always on always stay solid, when I try to use the u indicators the hazards lights comes on and stay solid.
