This method is for older Ford models. Follow these steps carefully:

3.1.1 Initiating a New Master Key

Insert the new key into the ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for 15 minutes.
Wait for the security light to stop flashing. You have 5 minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light will flash for another 15 minutes.
Repeat the process. When the security light stops flashing, you have 5 minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for 15 more minutes.
Finalize programming. After the security light stops flashing the third time, the new key has been programmed into the vehicle’s computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicle’s computer.

3.1.2 Adding a Key

Insert an existing key into the ignition cylinder.
Turn the ignition cylinder to ON (RUN) and back to OFF.
Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN).

Wait one minute before attempting to start the vehicle with any key.

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

This method applies to newer Ford models.

3.2.1 Initiating a New Master Key

This process typically requires special dealer equipment to erase existing key programming and set up the vehicle’s computer to accept new key codes. It often involves two ten-minute delays.

3.2.2 Adding a Key (Requires Two Original Keys)

Note: You must have two original, working keys to perform this procedure. If you only have one key, you’ll need to visit a dealer or locksmith.

Insert an existing (working) key into the ignition cylinder.
Turn the ignition cylinder to ON (RUN) and back to OFF. The ignition should stay on for at least ONE second.
Remove the existing key and, within TEN seconds, insert a second working key and turn it to ON (RUN) and then back OFF. Ignition must be in ON for at least ONE second, but no more than TEN seconds. Remove the key.
Insert the new key before TWENTY seconds have elapsed and turn it to ON (RUN). Leave it in the ON position for at least ONE second and turn back to OFF.
Check the security light. It will light up for THREE seconds to indicate that the new key has been successfully programmed.
Repeat steps 1 through 5 to program additional keys.
