1) The Problem (What “Not Locking” Usually Means)
Most “the lock is broken” calls are actually a latch/alignment problem. If the door isn’t fully closing and latching, the key won’t turn, the deadbolt won’t throw, or the latch won’t catch the strike.
- Key won’t turn: often tension from misalignment or a failing cylinder.
- Latch won’t catch: strike misalignment, door sag, or closer issues.
- It works sometimes: temperature/traffic changes expose a marginal alignment issue.
2) Safe Step-by-Step Checks (No Special Tools)
Check A — Is the door fully closing?
- Close the door firmly and listen/feel for the latch engaging.
- If it bounces or stops short, the closer speed/backcheck may be off or the door is binding.
Check B — Try the latch with the door open
- With the door open, operate the latch/lever and see if it moves smoothly.
- If it’s sticky or doesn’t retract/extend fully, the lock case may be failing or dry/contaminated.
Check C — Look at the strike alignment
- Are there fresh rub marks on the strike or latch?
- Does the latch hit high/low or left/right?
Check D — If this is an exit door with panic hardware
Do not remove/disable life-safety hardware. If the exit device isn’t latching or operating correctly, call a pro so the opening stays safe and code-compliant.

4) Local DC Context
In DC, many storefront and office doors see heavy traffic and tight schedules — “we have to lock up now” is a common call in areas like Dupont, Shaw, Navy Yard, Capitol Hill, and downtown. If you’re in a multi-tenant building, a property manager may also need documentation/photos for the repair.
