Research showed the srongest area for further developmental focus was the locking prompt, and more specifically the key chain. The reasons for this choice are self explanitory. The key chain is a cheap and simple area to address which is compatible with the needs of a student target market. I believe this will best solve student problems of forgetting to lock the door or not realising the need to lock the door to their student accomodation. The key chain will promt the user to consciously remember to ensure the door is locked so the accomodation is safe and secure.
