Your lock on the opener is probably engauged. On the wall control there is a button labeled lock. Press and hold this button for three seconds. Your remotes should work now. If they still do not work, you need to reprogram the remotes. Press the learn button on the back of the motor and then press and hold the remote button. The light will blink once. Repeat this step on the other remotes.
COULD BE A BAD REMOTE, I WOULD TRY ANOTHER ONE FIRST.
COULD BE A FREEZER ETC. PUTTING OUT INTERFERENCE.
OR
Anytime a door opens and/or closes randomly or doesn't work consistently I look for a smashed wire between the motor unit and the wall button.
If the wire is smashed the insulation becomes so thin that power will leak thru the insulation and activate the door or interfere with the remote signal.
Loosen the staples with a small screwdriver and slide the wire about ½ inch to move any areas of thin insulation away from the staples.
The second thing would be a bad wall button or a remote with a sticking button.
Or a remote in someone

I fixed it. No I know about the "vacation switch", thanks though. Shouldn't of had to reprogram "ALL" the remots all of a sudden. What I narrowed it down to was the receiver inside the opener. I removed it, got the part # and found a local dealer that had one in stock. Put the new one in, then I had to reporgram all remotes because it's a new receiver. Eveything is good again. $45.00 part. Thanks
Both of my vehicle's remote openers quit working on the same day this last week. The wall button works just fine, I was going to tear into it tomorrow and try and figure out the problem HELP
