Replace the door or get out your wood working skills and reblock the "lock block".

A deadbolt is useless in terms of security on a flimsy door like that. Agree that you should

replace it.

I agree. Can't believe they made doors out of Styrofoam

Hi, You may want to think of getting a door sleeve for the repair. Hanging a door is a piece of cake if you have done a few before, but the first one is a real bear, You need a hole saw, a plane, skill saw and a router with bits and the patience of a saint, just saying.

Good Luck Woodbutcher
