Lost keys are really such a hassle. Many of us have been through the struggle of simply losing or forgetting your keys when you need them the most. There are also people out there who have arthritis or Alzheimer’s Disease, which makes it harder for them to have keys since they either hurt them, or won’t even remember where the keys are to begin with.


Our project will essentially be aiding those who tend to lose their keys, have arthritis or Alzheimer’s Disease, and who want a safe with an extra level of security.  The safe will potentially make it easier to grab keep-sakes and special items without having to go through the struggle of dealing with forgotten and/or lost keys. 


Those who want a secure safe without the hassle of having a key, and can easily open and close the safe effortlessly.


Fingerprint Sensor



Rechargeable Lithium Battery





Electromagnetic Locking Mechanism

Technologies Utilized:

Electronics- To assemble the locking mechanism

Fabrication- To build the safe

Coding with Arduino- To program the fingerprint sensor

Our Research 

Product/Idea 1- Ardunio finger print scanner door lock~ Uses a fingerprint scanner to unlock a door.

Product/Idea 2- Iphone 6s~ Uses a fingerprint sensor to unlock phone . 

Product/Idea3- Stalwart fingerprint and digital steel safe~ Uses figerprint scanner to unlock safe.



Our First Rapid Prototype:

Today we are working still working on our second prototype, we are also figuring out how to hookup an Led and button (using a button because we haven’t received our finger print sensor) too an arduino .
