U'll need an electro-magnet and some soft metal same size as the magnet.

Some way to enter user info, like a keycard or Keypad with a combination lock. Some skills in building this kinda stuff.

Easy

How strong does the locking force have to be?

Have a look about 1/2 way down this page:

Seems to be a good way to get decent force with not much power.
