Three details worth separating
A key that will not turn, a latch that will not meet its opening and a door that rubs on the frame can feel like one problem when you are trying to leave. They are useful clues, but they do not establish a diagnosis on their own. Mention whether the symptom is new, intermittent or getting worse.
If you already know the key turns freely while the door is open but binds when it is closed, include that observation. Do not force the door or repeat a test on a jammed lock just to gather information. Describe what you have seen during ordinary use.
- Does the key enter and turn normally?
- Does the door close without lifting, pushing or pulling?
- Does the latch engage, and can the door be secured?
Repair the problem you actually have
The right work depends on the condition of the lock and doorway. An assessment may lead to a repair, a discussion about damaged hardware or another explanation for the binding. Ask what has been found and why the proposed work fits the symptom.
If the hardware works but you are concerned about old key copies, rekeying addresses a different need. If the door is closed and you cannot get in, explain that immediately using the emergency locksmith information as a starting point.
Keep the setting in the picture
Old Town includes both residences and businesses, so a catching door may be a private home entrance or a shop's customer door. Give the correct address and identify who can authorize the work. A tenant, manager or owner may have a different role in approving a change.
Our Old Town door guide explains how to describe an existing doorway without assuming its age or construction. If keeping particular hardware matters to you, say so before discussing a replacement. Do not assume a familiar-looking door has a standard lock inside.
