Well generally it's at my home. When I got to work yesterday it said 'low key battery' but it did lock. Unlocked when I got in it at work but wouldn't lock when I got home (15 miles). When I was driving it last week, it allowed me to open it at home, but then during the journey it said 'no key detected', key was in the car. I then stopped and switched the engine off and it wouldn't start. Eventually it did....thankfully. It locked when I got home. Next morning I go to it to drive to work and it wouldn't unlock. Yes there's the key to use but that set the alarm off and I couldn't switch it off.
