Rear doors and patio doors are rarely accessed from the outside by the owner and the vast majority of doors utilise Euro proile cylinder locks. As a consequence, making this lock inaccessible ensures the lock is much less vulnerable.  Research question / opportunityReferences1.

Crime Survey for England and Wales (2016) Retrived from http://www.crimesurvey.co.uk/This lock with the blank face set to the exterior of the property looks different and is intended to act as a visual deterrent and prevent a criminal attack. That being said, It works in a very similar way to a standard lock from the key hole side and therefore familiar to the user. Further development could explore the possibility and method of how to utilise the space available in the blank barrel to connect to the house alarm. Further still the lock could be designed to deform when under attack jamming the door if it is tampered with or struck. Conclusions / recommendationsProduct Design BA/BSc Yr.1 Lead Supervisor:  R.
