91 xj briarwood 4.0 auto , my xj has sat for about a month while it was waiting on parts to swap the tcase and when I put it all back together today and tried to start it i had to jump it off and the security light and head lights are flashing and it only runs a couple seconds and dies. I googled and found that the remedy is to unlock the door with the key but there was a key broken off in the driver door when I got it.

How do I make this run?

 

Problem solved
