So what's the Craic here.. Went into bmw Waterford today asking if I can get a battery changed in my key as it's not working. They said it can't be and have to replace the key at 190e, that what people do in these situations on these ? it was all good until today when as usual I was manually opening the car, I got the dreaded spin 90 deg left and right freely so clearly something has broke in the tumbler, thank god the car was open at the time but now I've no way to lock the car, the boot doesn't and the passenger side has no lock, yes I can fix the tumbler but I've read there not designed to be opened and closed long term like this, just another poor badly designed e46 part but I'm keeping my cool for now
