Door knob repair
We have Schlage door knobs such as the one in this link: http://consumer.schlage.com/products/ProductDetail.asp?styleID=48&functionID=29&finishID=5 with the "Bed/Bath lock (privacy)" style (under 'Available Lock Functions'). Recently, for one of the knobs, when we shut the door, although the door closes completely, the latch does not seem to click into place (with the 'strike'?) - as a result someone can push the door from the outside (without even touching the door knob) and open it.
Would appreciate any tips/guide to help me fix this issue.
