Unless I am losing my mind--possible--when I took delivery on my Abarth both doors unlocked when I pushed the unlock button on the key fob once. Now the passenger door SOMETIMES unlocks when I push the unlock button a second time. I went to the trusty Owners Manual, which says you can activate both doors unlocking by opening the driver's door, pushing and holding the unlock button for 5 seconds. I did that--and you could hear the driver door and the trunk lock and unlock once but didn't hear anything on the passenger side. I tried this several times, but unless I'm missing something, I just can't get the passenger door to unlock with the single key press. Does this sound familiar to anyone?
