I disconnected the battery for about an hour and reconnect and the security light is flashing and won't start.

Good morning,

I attached a guide for you to view for security reset. Try this and see if it works.

If it does not, you will need a locksmith to come to you and reset the system. They need to use the Ford IDS software to reset the security.
