I'm having a very sudden issue with my 2006 Crossfire. I'm gonna run through the past day and the current issue.

I started the car after work yesterday with no problem at 6pm. I made a few stops on my way home and it started perfectly each time. It was parked around 7pm.

Today I went out to leave and noticed that the rear and front running lights were on. I tried to use the key fob to open the door but there was no response from the key fob. I used the key to open the door and the alarm immediately activated its high pitched siren.

I attempted to start the car with the key. It sputtered like it was going to start and then died. It did that twice. I popped the hood and the alarm stopped. The front and rear running lights remained on. I left the hood open. I closed the driver door.

I proceeded to go inside and grab a different key fob. I returned to the car and tried to activate the locks with the second key fob, which failed. When I opened the door with the handle on the driver's side the alarm reactivated. I loosened and removed the battery cables from the terminal but the alarm continued to blast. I checked the owner's manual and removed fuse 9 from the hood fuse box. The alarm stopped. I reattached the battery cables. When I tried to start the car with the key there was no response..no sputtering like previously. There are no icons illuminated in the dash panel.

I have absolutely no idea what caused this as it was running perfectly at 7pm yesterday. It appears the lights being on may have drained the battery. I am currently waiting for someone to get to my house so I can try jumping the car.

Suggestions? Ideas?
