However one of the more common types of door locks found through the UK and Europe are cylinders locks. A cylinder lock is a lock constructed with a cylinder that a locksmith can easily unscrew should the key need replacing in the door, a lot of conservatory doors an UPVC doors use cylinder locks. The cylinder may contain any of a variety of locking mechanisms, including the pin tumbler lock, the wafer tumbler lock and the disc tumbler lock.
The first main advantage to a cylinder lock is that the cylinder may be changed without altering the locking mechanism of the door.
Standardised types of cylinder include key-in-knobset cylinders, rim (also known as nightlatch) cylinders, Ingersoll format cylinders, American, and Scandinavian round mortise cylinders, and Scandinavian oval cylinders. There are also standardised cross-sectional profiles for lock cylinders that may vary in length - for example to suit different door thicknesses. These profiles include the europrofile (or DIN standard), the British oval profile and the Swiss profile.
However like almost all types of locks cylinder door locks can be susceptible to Lockbumping, a method of entry to cylinder door locks that don’t require the actual key. The Lockbumping method is very simple an adapted (similar type) key is used, placed in a cylinder lock pulled back 1 notch or click, this is then struck firmly with a reasonably heavy object such as a small hammer or screw driver or even a purpose made hammer that can be purchased from many sites on the internet.
