If it was cranking strong, the battery is good. If the security light was on, that is the problem. It can be bypassed, but I don't recommend it. Also, jump starting doesn't by-pass it. I recommend taking it to a dealer and allowing them to diagnose and repair. In the future, if you allow the vehicle to sit with the key in the run position for ten+ minutes, the security light should go out and it should start.
