FORD 2004 Thunderbird v.1 - Manual (Page 71)

Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
Securilock
௢ keys can be used. To program a coded key yourself, you
will need two previously programmed coded keys (keys that already
operate your vehicle’s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are available, you must take
your vehicle to an authorized Ford dealer to have the spare coded
key(s) programmed.
Please read and understand the entire procedure before you begin.
1. Insert the first previously
programmed coded key into the
ignition from 2 (OFF) to 4 (RUN)
(maintain ignition in the 4 (RUN)
position for at least three seconds,
but no more than ten seconds).
2. Turn the ignition to the 2 (OFF)
position and remove the first coded
key from the ignition.
3. Within ten seconds of turning the ignition to the 2 (OFF) position,
insert the second previously programmed coded key into the ignition and
turn the ignition from the 2 (OFF) position to the 4 (RUN) position
(maintain ignition in the 4 (RUN) position for at least three seconds, but
no more than ten seconds).
4. Turn the ignition to the 2 (OFF) position and remove the second
coded key from the ignition.
5. Within twenty seconds of turning the ignition to the 2 (OFF) position,
insert the new unprogrammed key (new key/valet key) into the ignition
and turn the ignition from 2 (OFF) to 4 (RUN) (maintain ignition in the
4 (RUN) position for at least three seconds). This step will program your
new key to a coded key.
6. To program additional new unprogrammed key(s), wait at least twenty
seconds and then repeat this procedure from Step 1.
If successful, the new coded key(s) will start the vehicle’s engine and
the theft indicator will flash on and off. You may repeat Steps 1 through
5. If failure repeats, take your vehicle to your authorized dealer in order
to have new spare key(s) programmed.
