On the instrument panel there is a theft device light and it keeps blinking even after I hit the lock button. What could be causing this to keep blinking?

Pinpoint Test A: The Anti-Theft Indicator Is Always/Never On - Engine Cranks, But No Three-Second Theft Indicator Prove-out
Normal Operation
The PATS uses an LED indicator. This indicator will prove out for three seconds when the ignition switch is turned to ON or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily (for more than three seconds) when the ignition switch is turned to ON or START. PATS also "flashes" the theft indicator every two seconds at key OFF to act as a visual theft deterrent.
Possible Causes
no signal from anti-theft module
anti-theft LED is inoperative
PCM
circuit 645 (WH/LB)
circuit 343 (DB/LG)
NOTE:Large metallic objects, electronic devices on the keychain that can be used to purchase gasoline or similar items, or a second key on the same keyring as the PATS key may cause vehicle starting problems and record DTCs under certain conditions. If a fault cannot be identified, examine the customer's key ring for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS key while starting the engine. These objects and devices cannot damage the PATS key, but can cause a momentary concern if they are too close to the key during engine start. If a concern occurs, turn the key OFF and restart the engine with all other objects on the keyring held away from the PATS key. Check to make sure the key used by the customer is a Ford-approved PATS key. (PATS keys from Rotunda or Strattec are approved Ford PATS keys.)
