I recently installed a model 139.53930dm opener as a replacement unit. My keyless entry pad that worked on my old unit is a security+ model 139.53684. Are these two compatible?

Your new opener is on a different frequency and the old keypad will not work with it.

SOURCE: My Craftsman 53684 keyless won't work with my Craftsman 53930DM.

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 can try programming it but first make sure the battery is good. Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to your keypad and key in any 4 digit code you like and press enter.

THE FREQUENCY OF THE UNITS ARE PROBABLY NOT COMPATABLE THEY CHANGED ABOUT 2 YEARS AGO.

SORRY - I THINK YOU NEED A NEW KEYPAD TO GO WITH THE NEW OPENER.

Yes it sounds like you got the wrong keypad for your model opener.

Keylees entry won't work

If you have a wireless keypad do this: On the back of the motor unit just to the left of where all those white wires go you will find the smart/learn button. Press and immediately release this and then walk over and key in any 4 digit code you like and press enter. Should do you.

Sears craftsman keyless entry for model 139.53684

If I am correct, there is a green button on the opener. Hold that down until it stop blinki ng. Once it has, pres the opener. It should read the code and work the next time you hit the opener remote.
If not, sorry. This has worked for me
