Ford territory security code error after battery change how to restore

I think you mean that your vehicle is in theft mode /if so you must disconnect the battery cables again then reconnect them when the alarm sounds use your key fob to shut it off and you will be able to start the vehicle if you don't have one you must get a remote control key fob and follow programming instructions in the owners manual for your country of vehicle sale post back if you mean something else and explain it better I'm in the USA and I don't know if you mean that the dash light is flashing with a no start condition or is this an actual code we don't have your model vehicle here but I think that what I explained is what's wrong if not let me know and I'll try to figure it out the pats/secure lock system should be the same operation format for all countries good luck stephen
