Opener will close door but won't open the key pad works intermentily battery's good in remotes and key pad on the sensors I've noted the little lights one is green one is yellow

If the main light flashes 10 times when the door reverses to the open position it is your door sensors. Make sure the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have bad sensors.

Make sure the door sensors are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little.

Seems you've done everything right. Press and immediately release the smart/learn button and then walk over and key in a 4 digit code and press enter. If you are sure the battery in the keypad is good then I think your keypad is on the fritz or the wrong one for that opener.

If when you try to close the door the main light flashes 10 times and the door starts down and then reverses to the open position you have a door sensor problem. Make sure the lights in the sensors are not flickering ever so slightly. The color of the lights doesn't mean anything. The keypad sounds like a separate problem. Make sure the battery is good.

Check the aiming of the sensors at the bottom of the door. The little led lights shoud come on when aimed properly.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a little. If you cannot get both lights to come on you have a bad sensor.

Check your door sensors and make sure they are pointed at one another. Each of them has a small light that should be lit when they are properly aligned. Tweak them if necessary. If you can't get both lights to come on then one of the sensors has quit working.

The most common problem for your situation is that the battery in your wallmounted key pad needs to be replaced. unscrew the little screw on the face of the device, remove the battery and replace it with one just like it. Radio shack usually has these batteries

I can't tell if you're question is accurate, are you saying that the key pad will only open the door and never closes it or that it will only do one direction then you have to use the remote? If you're saying the keypad will not close the door at all, that may be a safety issue since closing doors can potentially damage property or worse, if your saying the remote works both ways then you probably need to reset your opener and keypad. Cut the power to the opener, leave it disconnected for five minutes. Reconnect and try keypad again. If this doesn't resolve the problem them you may have a bad circuit and will have to call a pro.

having all the remotes you want programed with you, find learn button on back of opener. hold button until little light goes out- no remote will work now, with each remote Press learn button once,Press big button on remote-light bulb on opener will blink on/off if bulb is working-do this each hand held-keyless is same way, put you 4 #'s in HOLD enter button-light bulb blinks on/off you have 15 sec. for each time you hit the learn button. also best to start off with new 9 volt battery before you start programing
