sorry for the delay............

then held one gdo button and the transmitter button, to no avail

You cannot Program from the Garage Door Opener Transmitter........
You have to press the Garage Door Opener Master Programming Switch located on your Garage Door Opener Motor

Press the two outside buttons of the GDO for one to two seconds, then immediately release them.
2.Locate the "Learn" or "Smart" button on the garage door opener receiver (located on the garage door opener motor-head unit). It is often found where the hanging antenna wire is attached to the motor-head unit and may be a colored button. Refer to the garage door opener operator's manual.

Press the "Learn" or "Smart" button. The garage door opener operator's manual may provide assistance in determining when the unit is in learn mode.
3.Immediately return to the GDO transmitter in the vehicle. Press and hold the button that is to be learned; the LED above the button will begin to flash slowly. When the garage door moves, immediately release the button. The LED will flash rapidly until programming is complete.
4.Press the button used during the learn operation again in order to verify that the GDO transmitter has been programmed.

The GDO is compatible with most, but not all, types of garage door openers. If the GDO LED does not flash rapidly after 90 seconds, there may be a compatibility conflict with the garage door opener.

Call 1-***-***-**** to address compatibility concerns or to help find the switch.
