This is a known issue with OVMS.... interferingyup, press the unlock on the key fob. Or the button the door if you can run around to the front in less than 2 seconds.
I've encountered a funny issue with my home charger where if I leave the car connected all night to let it balance the car will unlock in the morning but the socket stays locked. Seems that as the charger isn't pulling any charge its unaware there is a cable attached (well it is, shows connected when you try to start the car). I found switching off my charger with the key (I've got one of the much hated old chargemaster/polar units) and on again kicks it into life.
