Anti theft system has gone defective. You can try using your spare key if you have one, Turn the key to the "run" position and leave it set for 10 minutes or so, shut it off and see if the light goes away, if it does, make arrangements with a good mechanic/technician to bypass the security, if it doesn't you're probably going to have to get it towed to the dealer for repair.
