2016 fiat 500x. Battery, computer issue, or key fob?

[RBohannon]

I left radio on in car. Went back out key fob would not let me open door. I took out the emergency key to unlock door. Open door and alarm starts going off. Try to start and it does nothing. Acts like it stuck in on position. Still unable to do anything. We take the battery cables off let it sit about30 min. Plug back up still alarm going off. And does nothing from key fob. We took alarm fuse out so we can try resetting the key fob. Still nothing. Any ideas would be2 ²⁶⁶the only way greatly appreciated. Thank u

Battery has been discharged to the point that the voltage is too low for the car to operate correctly. Battery needs to be charged. You can remove the battery and carry it to auto store. Have it charged and bring it back.

I took the battery to advanced auto they checked it said it is good and it wouldn't hurt yo put on battery charger for a lil bit. So I did put it back in the car, put the fuse back in the car and alarm still goes off and still will not start nor just turn on. Is there an alarm mode or needing reset?

You didnt say that you charged the battery after the store suggested it. It should read about 12.6V with a voltmeter.

Replace the Battery in the Keyfob...CR2032

You may have rain water leaking on the RFHM module which might cause a no start condition. See thread below.

Edit: If I remember correctly when you open the door with the emergency key the car looks for the keyfob signal. If it doesnt see the keyfob signal it considers it a break-in. Thats why I say replace the battery.

If you are somewhere away from home and you think the keyfob battery is dying/weak...hold the keyfob against the start button and press the button with the keyfob.
