While most uPVC and other double glazed doors have good construction and feature strong multi point locking systems - they have a weak point which is being exploited by burglars in the UK.
According to the BBC & data from the Police 27% of all burglaries involved the euro cylinder being snapped - in just 15 > 90 seconds in most cases.
Yale and Millenco have now produced locks that have anti snap features that are BS TS007 rated. This British Standard may well be a requirement from insurance companies in the near future in the same way they currently insist on 5 lever mortice deadlocks on traditional doors.
I've attached a link to Yale's main site, which explains their new cylinders in more detail and also shows you how to replace your existing cylinder. All the new Yale anti snap cylinders are in stock and available at discount prices from Lock and Key.
