I had an X1 stolen from my drive 4 cars back – must have been cold call cased the joint – we never totally dead locked front door – so wire through letter box got keys to car – pushed it quietly out and off .
It was very professional didn’t take any other valuables from house – so now keys in faraday pouch that are kept in a faraday box – out of sight- far less chance of amping up signal – front door properly locked – ring camera on front door bell – I make sure nothing can be obviously seen if front door is open and always close kitchen door before opening front door – we have a police sign no cold callers – it used to be respected – but less and less these days – usually under the guise of charity work – but who knows.
So try to air on the side of caution whilst trying not to be too paranoid or stressed – hope maybe some of this helps 👍
