P1260 2002 Ford F150 Code - Theft Detected - Vehicle Immobilized

This code indicates that the vehicle's anti-theft system has detected a theft attempt, leading to the immobilization of the vehicle.

Common symptoms include the vehicle not starting, the engine cranking but not turning over, and the security light flashing on the dashboard.

Possible causes include issues with the key transponder, a faulty PATS (Passive Anti-Theft System) module, a disconnected or damaged wiring harness, or a problem with the ignition switch.

Diagnosis typically involves checking for other stored trouble codes, inspecting the key for damage, ensuring the key is programmed correctly, and testing the PATS module and associated wiring.

Resetting the code may not resolve the underlying issue causing the theft detection. It's recommended to diagnose and address the root cause before attempting to clear the code.

Driving the vehicle with this code may not be safe or possible, as the anti-theft system may prevent the engine from starting or functioning properly.

Repair options include reprogramming the key, replacing a faulty PATS module, repairing damaged wiring, or addressing any other issues identified during diagnosis.

A locksmith with experience in automotive security systems may be able to assist with reprogramming keys or addressing issues related to the anti-theft system.

Disconnecting the battery may temporarily clear the code, but it's important to address the root cause of the issue to prevent the code from reoccurring.

Costs can vary depending on the specific cause of the issue, but repairs related to this code may range from a simple key reprogramming to more complex module replacements, potentially costing a few hundred dollars to over a thousand dollars.
