I have two '07 Santa Fe's and two OD Phantom openers with the rolling code
units. Following the instructions in the manual I can program one of the
openers for button TWO of both cars and they work fine.

But I cannot program button ONE of both cars. They will NOT program.
However, the separate remote does open the door.

Is there a button sequence of programming that I am unaware?

Here's what I do:

Press the "program" button on the opener unit. The LED blinks.
In the car, with the ignition on, I press the button for two seconds and
release. Then I press it again for two seconds and release. No rapid
blinking.

When I programmed button TWO after the 2nd release the LED started blinking
rapidly indicating it was programmed (and it was).

Any ideas why neither car can program this ONE opener? BTW - I cleared the
receiver memory on the DO and reprogrammed the remote and it programmed
fine. Just not the cars.

Ideas ?
