2000 Explorer Error Code

Hello, i recently purchased a 2000 Explorer, i had a mechanic check the vehicle over before my purchase and he found error code P1206 Theft Detected Engine Disabled, i believe this is correct his writing is hard to read , this vehicle did not come with the key fobs and i was wondering if this might be something that was bypassed because the fobs are missing , the vehicle is equipped with some kind of theft option as the word theft blinks inside the instument cluster when the vehicle is turned off, so i guess that means one of two things , it is either actually equipped with some sort of theft device or the police are gonna be banging on my door in the near future :shock: , lol , thx in advance.
