Thanks to the efforts of motor manufacturers and insurers, it is now virtually impossible to steal a car without the keys. So car thieves have started burgling houses and nicking the keys instead. In 2008/09, the Home Office says that 19,400 cars were stolen after car key burglaries, or 53 a day. One particularly impressive new skill is slipping a fishing rod through the letterbox and lifting the keys from a hall table or convenient hook by the front door. According to the insurers I spoke to for this article, car crime is now taking place on “an industrial scale”. But they also admit that they have no idea if it’s a genuine increase – or if their new systems are only now revealing the full picture.
