You can use solenoid and iron rod of electric calling bell

I have tested this

If you supply desired VA to solenoid, Iron rod [with a spring]
Inside it will move. You can use this movement to open or close door

This is not a very efficient way

Konbanwa,
You can also try using a windscreen wiper motor or start motor solenoid or central door lock motor extracted from a car.
