was excited to get new front door lock but became very disappointed when it arrived and as I installed it , I found that the interior door knob did not work and the screws need to attach it to the exterior handle were missing. then as I attempted to install the exterior handle to at least cover the door hole while waiting for a replacement knob. the post used to attach then exterior handle broke off from the handle as I was screwing the screw in to it bad welding of parts. poorly made for a handle costing almost 100 dollars.
