Keyless Dorm Entry

Step 8 Conclusion

The end result of the project is a fully working door that can be opened from without a key. The total cost of the project is under $40 which is a very good price for the final result. A lot of enhancements could easily be made. For example, the system currently is not able to relock your door, but such a thing would be trivial to add into the code. It wouldn't be too difficult to add some different ways of unlocking the door, such as texting a number or making a microphone to listen for a secret knock.

Why don't you just change the lock in a automated door lock, would make things a whole lot easyer, and cheaper if you think about it

"This must also be accomplished without modifying the door in any unauthorized way."
He lives in a dormitory, where it's probably highly regulated what one can do with their room (including the door).

 Wont you still need to have a key to close it, unless you have it automatically closes itself. Instead of using a string that just pulls it open, use a metal line, or straight piece of metal that can open and close the deadbolt.

Yep. I will most likely make that modification, or add a 2nd servo in the future for that reason.
