My wired key pad in the garage opens and closes the door but the buttom keeps blinking fast. My two car remotes stopped working. My remote key pad on the house works. Whats with the fast blinking and why won't mr car remotes work?

Using a step stool, reach up and remove the covers (the white covers pop off). The instructions will be labeled on the back plate for setting your remote control's security code Make sure the remote has a battery installed and is compatible with your garage door opener. Or go to the LiftMaster web site and down load its operators manual.
.

Try this method for programming. Press and hold the button down on the remote while you press and immediately release the learn button. Do this for each remote.

Have you replaced the battery in the keypad? Try this:

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 the keypad and key in any 4 digit code you like and press enter.

Post back with your results.

Try pressing and holding the lock button for 3 seconds to stop the light from blinking. Your wall control may be bad. Usually when that light is blinking it is the remotes that will not work.

Press and hold for 3 seconds the button on your wall control that has the lock icon.

It is related. One of the buttons on your wall control is the lock button and has a lock icon on it. Press and hold it for 3 seconds. The blinking should stop and your remote should now work.

TRY DISCONNECTING THE WIRE TO THE WALL BUTTON. IF THE VISOR REMOTE NOW WORKS YOU HAVE A BAD BUTTON.

HOPE THIS HELPS

this just happened to us today as well. the wall pad has three buttons: one large back-lit button pad to open it and a lock button and a light button. the open button was blinking quickly and would open the door, but the car remotes did not work. I found that by pushing both the "lock" and "light" button at the same time for about 3 or 4 seconds, the back-lit "open" pad stopped blinking and went to steady green. I went back to the cars and checked the remotes there. both opened the door.

hope this helps someone out there

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.

ajust the signle

Assuming, from what I read, the remote works..The inside switch is just a doorbell switch which will wear out or have the contacts get bent or dirty. Take off wall, and change for new one or see if the contacts can be cleaned or adjusted. If the pad is electronic (coded) the wires may be bad or the control defective. Usually momentary contact of the two wires will cause the door to actuate.
