Cylinder snapping seams to be a growing concern. You feel your home is secure because you have a 5 point locking system, but the truth is your door may not be as secure as you
think get a professional in. If you are not sure how secure your UPVC (plastic) door is then please feel free to call and book an appointment for me to check for you. as the surveys are free with no obligation to have anything installed, the same will apply for a lot of businesses that have the Euro profile cylinder on there main entrance doors or side doors.
