B1213 on Ford
Anti-Theft Number of Programmed Keys Is Below Minimum Value
B1213 on Ford vehicles indicates anti-theft number of programmed keys is below minimum value. Au7o has documented this code across 1 Ford model — most commonly on F-150. A Ford/Lincoln/Mercury code from the PATS (Passive Anti-Theft System, also marketed as SecuriLock) immobilizer, used on 1996-and-later Ford vehicles. It means fewer than the required minimum number of coded keys are programmed to the module — normally two. In most cases the vehicle still starts and drives normally on a programmed key; the code is the system reporting that it has no valid spare. Programming requires two working coded keys and, on many model years, a dealer-level scan tool. Typical repair costs on Ford range from $100 to $500, depending on the specific model and root cause.
Common Causes of B1213
- •Only one key programmed after a key was lost, replaced, or added
- •PATS module, instrument cluster, or PCM replaced or reprogrammed without re-programming the full key set
- •Key programming session interrupted or a battery disconnect/dead battery during programming
- •Damaged or failed transponder chip in one of the keys
- •Faulty transceiver ring/antenna around the ignition lock cylinder
- •Wiring or connector fault between the transceiver and the PATS module

- PATS Anti-Theft No-Start — Cranks but Won't Start with Theft Light Flashing1997-2004
The Passive Anti-Theft System (PATS) on these trucks disables fuel/injection when the PCM cannot verify the key transponder, leaving the truck cranking but not starting with the dash theft/security light flashing rapidly. Common triggers are a worn or dead key transponder, a loose or damaged transceiver antenna ring around the ignition cylinder, corroded PCM grounds (water intrusion at the passenger cowl/windshield), or intermittent PCM power. It often starts as an intermittent no-start that worsens.
