Hi , I need HELP to secure my Van door.....the story.......

I went out to my 2005 van this morning and put my key into the "missing" key slot ( it was 5am and dark ) its GONE !

Also the door was unlocked.......GRRRRRR

I have been using my "Ghetto " anti-theft devise , a big heavy chain locked to the seat frame and then locked around the steering wheel !
So the van was still there at least.......

HOW do I replace the door lock ? Do I need to buy a complete lock with pull handle etc or just the lock parts ?

Anyone have photos on the back side of the door handle / lock area ?

Or a YouTube video ?

Thanks for your help

UPDATE- I found a you tube video where a girl takes out the whole lock......pretty poor video with no close-ups

BUT on the workbench it shows then tapping out the old lock after pushing a small tab and "pushing" it in the new door handle !
Is that all thats holding the lock in the handle ? a press fit and that small tab ? can I superglue it in or ?????

Thanks again.....
