How to Program a Chipped Ford Key

Programming a chipped Ford key can save you a significant amount of money compared to dealership prices. This guide provides step-by-step instructions for programming transponder keys for various Ford, Lincoln, and Mercury vehicles.

Ford’s Passive Anti-Theft System (PATS), also known as SecuriLock, utilizes a transponder chip embedded in the key. This chip communicates with the vehicle’s computer to disable the starter unless the correctly programmed key is used. Even if you have a key with the correct cuts, without the programmed chip, your Ford won’t start.

This guide covers two primary programming methods: “B” for older models (1996-early 1998) and “C” for newer models (later 1998-newer).

Programming Method “B” (1996 – Early 1998 Ford, Lincoln, Mercury)

This method applies to older Ford, Lincoln, and Mercury vehicles.

Initiating a New Master Key:

1. Insert the new key into the ignition and turn it to the “ON” (RUN) position. The security light on the dashboard will flash for 15 minutes.
2. After the security light stops flashing, you have a 5-minute window to proceed. Turn the ignition “OFF” and then back to “ON” (RUN). The security light will flash for another 15 minutes.
3. Repeat step 2. The security light will flash for a final 15 minutes.
4. Once the security light stops flashing for the third time, the new key is programmed. This new key replaces all previous key codes and becomes the sole programmed key.

Adding a Key:

1. Insert an existing working key into the ignition.
2. Turn the ignition “ON” (RUN) and then “OFF.”
3. Remove the existing key and, within 15 seconds, insert the new key and turn it to “ON” (RUN).
4. The security light will illuminate for two seconds, confirming successful programming.
5. Wait at least one minute before attempting to start the vehicle with any key.

Programming Method “C” (Later 1998 – Newer Ford, Lincoln, Mercury)

This method applies to later models and requires two existing working keys.

Initiating a New Master Key:

This process requires specialized dealer equipment to erase existing key programming and prepare the vehicle’s computer for new codes. Two new keys are required for this procedure. Contact your local Ford dealership for assistance.

Adding a Key:

Important: You MUST have two original working keys to perform this procedure. If you only have one key, you must visit a dealership for programming.

1. Insert a working key into the ignition.
2. Turn the ignition “ON” (RUN) and then “OFF.” Ensure the ignition remains in the “ON” position for at least one second.
3. Remove the first key and, within 10 seconds, insert the second working key and turn the ignition “ON” (RUN) then “OFF.” The ignition must be “ON” for at least one second but no more than 10 seconds.
4. Remove the second key. Within 20 seconds, insert the new key and turn the ignition “ON” (RUN) for at least one second, then “OFF.”
5. The security light will illuminate for three seconds, indicating successful programming.
6. Repeat steps 1 through 5 to program additional keys.

Important Considerations

• Always wait at least one minute after completing any of these procedures before attempting to start your vehicle.
• These instructions may not apply to all Ford, Lincoln, and Mercury vehicles within the specified year ranges. Consult your owner’s manual or a qualified locksmith for vehicle-specific instructions.
• While these methods can save you money, if you encounter any difficulties, it’s recommended to consult a professional.
