All our spare keys are kept in a tin where I keep a bit of cash and my iPad when I am out. We never used to think our cars in any way vulnerable until my daughter had her keys taken from her pocket on the tube. She must have been followed home as her car, small, old, ordinary, was stolen that night. It was then used to ferry drugs around a nearby area until it was spotted by a neighbour but since the keys were not found it was written off by the insurance company. It would have cost the value of the car to replace the locks and deep clean to remove the stink of drugs. It cost her money she didn’t have to get another car but fortunately the thief didn’t use the keys to break into her flat. The police said drug runners go for old, nondescript cars as they are less likely to draw attention to themselves.
