Central locking has stopped working

[DanaElizabeth]

Anyone able to shed some light as to why my central locking and windows have stopped working? Went to get in my car to go out and had to unlock it using the key which only unlocked the drivers door. I had faint writing of the word ‘fuse’ on the dash and it wouldn’t turn over as if the battery was dead. So started it using jump leads but I don’t think it’s battery related as the time, date and millage didn’t reset and I turned the car straight off and started her back up fine straight away without the jump leads. My interior lights and puddle lights have stopped coming on when the doors open, but comes on when you switch them on manually. I still have things like my electric mirrors and other electrics such as dash lights and external lighting, headlights etc. Anyone got any idea?
