I've never seen the first set of steps you mention. You always need to press the "learn" button first so the opener will be in the mode to capture the new code. As far as I know it is not necessary to hold the Enter button on the keypad (at least I never have). While the "learn" LED is lit on the opener, just key in the new code and press Enter.

Maybe you should try clearing the receiver first by pressing the "learn" button and holding it until the LED either goes out or starts flashing (depends on model). Then try reprogramming. Maybe the little computer is confused.

you seem to be doing right thing, hold learn button for 10 seconds, this should clear out all coded items; keypads, remotes.

My best advise to you is get the brand name remote for your opener. I know it sounds like a pain but click brands are not super great because there supposed to work for many different kinda. For the most part you can call your local garage door dealer and pick one up for your opener. They may sell you a lift master brand opener which is find sears/liftmaster/chamberlain are all the same. Should only be about 35 bucks if you pick it up

I just found the solution for my 'ancient' Sears garage door opener, model # 139.655000, and I figured I'd share it.

There's a separate radio module, wired to the main opener. This module is small, has a short wire/antenna, and plugs directly into an outlet.

There's a manual open/close button on this module (I didn't realize this until I got up on a ladder). This button is also a removable cover; underneath it is a "smart actuate" button -- this is your learn button.

What I did was: unplug the radio module. Pry off the cover. Plug the radio module back in. Hold down the button on the remote. Press the "smart actuate" button. This programmed my remote successfully!

The button should be on the back of the motor unit. You may have to remove a light lens to find it.
