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.

Do not get angry and do not be harsh because you will never regret being kind

How strong does the locking force have to be?
The very first course in engineering school should be how to use Google and Wikipedia
I very often misspell or miss things while making posts so come back and double check a few times.
I also have a full time job and often 10 projects going on at the same time so I'm not always online.

Have a look about 1/2 way down this page:
Seems to be a good way to get decent force with not much power.
