Kwikset TITAN Cylinder replacement and hinge adjustment

"I can't lock it, so I want you to replace it."

I couldn't understand the situation well on the phone, but when I arrived and looked at the front door, the quick set TAITAN had completely faded.

Moreover, the cylinder core is missing.I couldn't understand how this would happen, but I decided to disassemble it and replace it with a new KABA cylinder.

The front door is also quite tilted and is not perfectly aligned with the strike.The hinge is deformed and the mounting screws are rotten.

It seems that there is no choice but to remove the hinge and correct the deformation.After that, I adjusted the position of the strike.
