Programming new FOBs

While troubleshooting my CEL, I came across this little nugget. I did a quick search on here but didn't see a post about it. Sorry if my Search-Fu was weak:

When the keyless operation key is lost or additional keys are requested, the emergency key and the keyless operation key must be used to register key ID.
caution
Two keyless operation keys that have been registered are needed.

Turn the ignition switchto the "ON" position using the registered emergency key and keylessoperation key.
After turning theignition switch to "ON," press and hold the UNLOCK button of thefirst registered keyless operation key for 4 to 10 seconds, and press the LOCKbutton during that time.
Within10 seconds after pressing the LOCK button in Step 2, release the LOCK buttonand then UNLOCK button. (Perform within 30 seconds after completion of Step 1.)
Then, press and hold theUNLOCK button of the second registered keyless operation key for 4 to 10seconds, and press the LOCK button during that time.
Within 10 seconds afterpressing the LOCK button in Step 4, release the LOCK button and then UNLOCKbutton. (Perform within 30 seconds after completion of Step 3.)
The immobilizerindicator starts flashing, and the mode shifts to the keyless operation keyadditional registration mode.
Check that theimmobilizer indicator flashes, and press the LOCK button of unregisteredkeyless operation key twice. KOS starts registration communication with thekeyless operation key.
After the additionalregistration of keyless operation key is completed, the data is recorded toEEPROM, and when the data recording is completed, the immobilizer indicatorflashes for 30 seconds.
When a new keylessoperation key is additionally registered, repeat Steps 1 to 8 after theignition switch is turned to "LOCK" (OFF).
The keyless operationkey addition is terminated if any of the following conditions is met.

The additional registration of keyless operationkey was completed.
The signal of LOCK button operation was receivedfrom the keyless operation key which was registered in Step 8.
Within 60 seconds after shift to the keylessoperation key additional registration mode, the operation in Step 8 does notcomplete.
Before the registration communication withunregistered keyless operation key starts, the ignition switch was turned to"LOCK" (OFF).
The registration communication failed.
The recording to EEPROM failed.
