I need answers about a ignition problem.

Ok lets see i own a 2012 VW Jetta S and i have had the
ignition replaced once already but didn't resolve
issue...when i go to shut of the car it sticks horribly to the
point where i have broken both keys. Now today i went to
shut car off and the key wont turn off at all. It's a 5 speed
so the only way i could shut car off is by staling it out and
disconnecting the battery to shut down the day running
lights. WTH could b the problem before i go spending
thousands trying to get it fixed.
