How to program chipped keys?

[mr.13secprobe]

I heard it can be done easily if I have two keys that are already programmed.

I just need to program the spare key that is in the starter box.

I saw dealership doing this with two programmed keys but wasn't really sure how he did it.

Anyone knows?

Actually the person who decided to try it out for the 3 took the instructions from a ford focus manual.

The timing is critical to this procedure, please read through the entire procedure before attempting.
Procedure:
1. Insert one of the pre-programmed transponder keys and turn the ignition to "on", leave on for at least one second (I wait until the red key symbol in the instrument cluster extiinguishes), remove the key from the ignition.
2. Within 5 seconds insert the second pre-programmed key and urn the ignition to "on" for at least one second but no more than 5 seconds (use the key symbol for this as well) then remove the second key.
3. within 10 seconds insert the new key in the ignition and turn the ignition to "on", if you are successful the red key symbol will illuminate then extinguish after about a second.

If you are not successful the red key symbol will flash repeatedly to indicate that you have inserted an invalid key. Remove the key, wait a minute and try it again, it took me a few times to get it perfect and I had done it before.

There is a way to do it without actually inserting the new key in the ignition. because my new key is in the black box(remote starter) and the dealer actually just did it without removing the key out of the box. and i'm not sure how he did it. Hope you know what i'm talking about.
