My Liftmaster gates have, as of yesterday, started opening themselves. Yesterday my keyfobs (4 of them) started to either not work or only one of the gate opened. I tried to reset by turning off/on the power and even tried to re-learn the keys. But still only the one gate opened (CH1). After leaving for a while I retired the gates via the keypad and both gates opened and then the keyfobs started to work again. Later I found the gates were fully opened so I closed them. At 3AM this morning I heard them open, so I closed them and then 10-20mins later I heard them open again so I turned off the power. This morning I powered them back on and later found them open again.
