Re: change code on keyless entry. Now the remote does...
Did you clear the codes existing in the unit? (Press and hold the learn button; LED light will stay lit for approx. 6 seconds.) If you have remotes that have dipswitches, pop the battery cover off and make certain that all switches are set identically in each remote. Now, press the learn button on the main unit and immediately release. While its LED light is lit, press the button on ONE of the remotes only. They will ALL be programmed at this point. Now, press the learn button once more (quickly and release) and enter your number code on your keypad and press enter. It should be programmed now, too.
I was having a similiar problem, and this turned out to be the solution. Before, I was programming both remotes, not knowing as I did so that by programming one, and then another, I was UNprogramming the the first as well as the keypad.
I hope this works for you. It did for me.

It actually depends on what you are trying to program. And these instructions apply only to openers that do not have dip switches on them.
Remotes: push don't hold the colored learn code button all models have different colors.
After pushing the button hold the remote behind your back and push it three times. On the third time the door should run.
Keyless Entry: Program the code you want into the keyless. Push the colored learn code button and then enter the code and push enter three times slowly. on the third time the door should run.
Home-Link. Hold the two outer buttons until the blinking pattern changes. Then hold the button you wish to program and point and click your remote at it. Push the colored learn code button and push the homelink button three times.
There are two models of the Wireless Keyless Entry System, the 740CB and the 940CB. The 940CB is for use only with Security+® garage door openers having an orange/red smart/learn button. The 740CB will work with all openers manufactured since 1990 that have a yellow, white, gray, or green smart/learn button. It will not work with Security+® openers.
To program the keyless entry, first locate the smart/learn button. On our chain drive models, this button is on the end farthest from the door. On our belt and screw drive models, it is on the right side as you face the door from the opener. You simply press and release the smart/learn button. You now have 30 seconds to enter your four digit PIN number into the keypad and hold the enter button for five seconds. Wait one minute and test the keyless entry by entering your four-digit PIN number and pressing enter.
With some Security+® models, you can also program your Model 940CB Wireless Keyless Entry without climbing a ladder, right from your Multi-Function Control Panel. Simply enter your pre-selected code and press and hold the enter button on your Keyless Entry. Then press and hold the light button and the pushbutton on your Multi-Function Control Panel. The garage door opener lights will flash to confirm that the Keyless Entry has been successfully programmed.
Hope this helped you solve the problem.
All the best my dear friend.
Ted, it sounds like normal garage door function. Here is my take, you were pushing the button in a fashion that was to clear all remotes. This is done through either pushing wrong button, or pressing the programming button for too long.
Sometimes you need an assistant to be able to activate the wireless key, soon enough after pressing programming button. Get a ladder and a light, climb up and read the directions carefully on your opener. Try to add just the keyless system.
If that does not work,Get an assistant, and do the whole process again, including the keyless.
There are two distinct processes, adding and clearing, and it may be easy to invoke the wrong one.
Your system uses rolling code/invite system. Rolling code relates to a handshake betewen each remote and the base. The code is changed at each use, for each remote. (the keyless /wireless also).
Been there, done this. all for an additional second or two of button press.
Coding the keypad will not affect the remotes if you follow these directions.
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 a four digit code and press enter.
We have a Chamberlain Whisper Drive Plus. The keyless entry stopped working, suddenly. I have changed the battery, not the problem. I cannot get it to work, and cannot get it to reprogram. The keypad lights up when buttons are pressed, but when I press "Enter" the whole keypad flashes for about 30 seconds and then just goes dark.
The remotes and keypad use the receiver which is part of the logic board.'t The button on the wall is hardwired and doesn't use the receiver. You might pull the logic board and check for bad connections on the printed circuit.
make sure it is the right keyless entry. For starters, Make sure your antenna hanging off the operator is "purple" color. If it is grey, you have the wrong keyless entry. The keyless you have is for the 315 frequency. If your antenna from the operator is grey, you need to get another keyless entry based on the frequency.
If you can program your remotes but when you program your keypad the remotes quit working and vice versa you have either the wrong keypad or it has reverted to an earlier technology. Make sure the keypad is for your specific model door opener.
There are two types of technology with this operator (rolling code and non-rolling code). This operator will except one or the other but not both. It is not uncommon for a rolling code (Security+) remote or keyless to lose the "rolling"part of its technology and become a non-rolling code device so it is not compatable with the rolling code technology. You will need to replace the one remote or keyless that is not like the others.
easyer then that , you die!
Open your garage door, take out the step ladder, a chair or get up on *********** in law's back, (here's your chance to be on her back for a change) press the read button of your unit (motor) a led should light up and on the key pad, key in the new 4 digits code and press enter, the light of the unit should blink
