A simmple Gadget wich turns the key in the lock.
Take attention for the direction of the door. Maybe you have to mirror the card.

I used a simple gearmotor with 12 V DC and 45 RpM. Searcht it on Ebay or Amazon...

Its controlled by a Raspberry. I combined it with a nfc reader.

!!! NOTE !!! IMPORTANT !!!
There is no way to turn the key from the other side of the door! Better you install a backup to move the "Keycard" away! (Maybe a thin but strong wire to tear it of from outside).
