What happens if you dont shut the door before the lock re-engages?

It would necessitate having to re-enter the code....


Not the best of ideas I'm afraid....


The lock mechanism could be a simple solenoid...Can you get one of them in Nigeria?

The chip isn't really made for this application. Your senario would reqire additional logic to keep the lock from engaging while the door was open.

The lock should be i such any way that it can close even if the circuit power output is gone. Just like you can lock some doors without the key but opens it with only the key.

Then you need something like these strike plates.

Won't be as secure as an electric dead bolt, however.
