Sounds like the anti-theft system does not recognize that the loss of battery power was from intentional battery changing. Have them try to disconnect the battery for ten seconds and then reconnect. Upon reconnecting the horn should blow one time. If the car still does not start you may have a problem with the security system computer itself. This will require a dealership with the proper computer tools to diagnose and repair. Good luck.
