Front door latch only half way out?

Question

It was working fine and the one of the screws got loose which I put back on my kwickset door knob Door knob latch was working fine before. I had problem locking it from inside but I did something and it is working know, except that my latch is normal full extension if I do not tighten inside screws. Once tightened latch is only half way and does not secure door. Even the wind can open it. I tried removing and adjusting side plate but no luck. I did grease the parts with white grease. Any suggestion or web sites with videos. What did I do wrong

Answer 1

I've seen this before with Kwikset locks. The latch mechanism, which fits in the side of the door, is binding. With the doorknobs loose, make sure that the latch is seated properly and the two screws that hold it in the door are tight. Then tighten the doorknob screws equally while making sure that the doorknobs are seated properly. Alternate when you tighten the screws, turning each a little bit at a time. If the latch is still binding, you may need to loosen the screws a little bit.
