I recently got this s60 t6 awd with polestar badging, it’s great outside of some issues.

One of which is getting my doors to unlock using the “smart key”(not sure whether it’s the type that unlocks upon getting close). I’ve been using the manual key but the siren alarm always goes off.

I got 2 keys both of which lock the car remotely but every other function fails(no unlock, trunk, siren etc) every button just locks the car, except I was able to get it to unlock once for reasons I can’t explain.

I can unlock the doors from the inside drivers side buttons. Can rule out key fob battery, door latch/actuators, I don’t think it needs a reprogramming but honestly not sure. I think there is something wrong within the cars electrical systems but I don’t really have much evidence outside of both the keys presenting similar symptoms. Any ideas?
