forgot to mention that I did try locking and unlocking the doors using the remote and inserting the key into the drivers door. that did not help
But after disconnectin the battery over night, in the morning the car did start and everything is ok now. I think just disconnecting it for 20 mins or so may have done it, Also when I first disconnected the battery the door may have been open and the doors unlocked which may have set the alarm off. before disconnecting it the second time, i closed the doors and locked them.
