Ford Key Types: What You May Be Dealing With
Ford vehicles manufactured since the mid-1990s use Passive Anti-Theft System (PATS) transponder keys. The key contains a small microchip that must be electronically matched to your vehicle's PCM (powertrain control module); without that programming, the engine will crank but refuse to start. Older Ford models — think pre-1996 — use a straightforward mechanical key with no chip, which is the simplest and fastest replacement scenario.
Newer Fords rely on more sophisticated systems. Key fobs with integrated flip-key blades (common on models like the Focus and older Fusion) combine a transponder chip with remote lock/unlock functions and need both blade cutting and fob programming. Fully keyless Intelligent Access fobs — found on recent F-Series trucks, Explorers, Mustangs, and Edges — communicate with the vehicle continuously and require specialized OBD-II programming equipment to add a new fob to the car's system. Our mobile units carry the professional-grade Ford-compatible programming tools to handle all of these on-site.
