What could be the problem?

If your check engine light is on get it scanned. If not pull the camshaft sensor and make sure the magnet is still in place on the cam shaft. You might need to crank it once or twice to turn the camshaft.

When you turn the key to start does the starter engage an spin the engine ? or nothing happens .
the lights and music come on but the motor will not start when I turn the key ??????? Will not start how ?
crank - no - start or no crank no start . ????????

That symbol means low voltage in the system, you have a dead or defective battery. These new sealed batteries can go out of the blue, starts fine and then a few minutes or hours later nothing, no crank no start. You can confirm the battery is the problem by honking the horn, it will dribble out a noise or not work at all if the battery is dead or nearly dead.

Sounds like a bad crank sensor to me.

could still be the alternator bad,they only check for voltage on it not amperage

very well could be due to anti theft issue. i don't recall the keys getting locked in the ignition from this though. try turning the key to the on postion- not cranking and leave it there for 15 min, then turn back off. do this three times. you may get a blinking light on the dash- don't worry about it. on the fourth try and start it. what you are doing is telling the alarm- i have the proper keys so let me take my car!

unplug from the wall about 1min then plug back in this will reboot the cpu on the machine

Fuel pump.

Briannatara:

Some questions to help in the analysis........

You say "it cranked for about 3 seconds and died as if I turned off the key" did it actually start and then die?
Have there been any clues (unusual happenings) recently that might relate to the current problem?

Is there a reason the battery went dead? was something left on? Lights, etc?

How old is the battery?
