Cuda door latches, I have a problem

Ok, car is a 1970 Cuda.
Problem is I close the doors, and lock the doors with the key, BUT I just pull up on the handle and it opens like it was never locked??????????????????????

what gives, they supposedly worked just fine before, All i did was replate them

Possible the key cylinder linkage rod/arm is installed incorrectly?, or drivers lock cylinder in passenger, passenger in drivers?

Thanks Mike,
I figured it out this morning, all it was the exterior linkage adjustment was out ever so slightly and wasn't moving the lockout arm enough.

re-adjusted both sides , now they work



On to the next problem
