THE SHORT ANSWER
If a door closes but will not stay shut, watch whether its spring latch reaches the opening in the metal strike plate on the frame. Misalignment, loose hardware or a latch problem can be involved. Do not slam the door or file the strike first. A security or fire-door problem needs prompt qualified attention.
Before you try anything
Keep fingers clear of the door edge and hinges. Avoid closing a door that may trap someone or block the only safe exit. Never tape back a latch, disable a closer or wedge a fire door open. Report a door that cannot provide required security or fire protection promptly to the property manager or qualified door service. If someone is trapped or there is an immediate emergency, get emergency help.
Before you begin
For a hinged household door with a conventional knob or lever and spring latch, where you can move safely around it. Covers visible observations before repair. It excludes a jammed-shut door, lockout, smart-lock programming, deadbolt repair, glass doors, hinge removal and adjustments to fire-rated or self-closing assemblies.
A phone for photos, a flashlight, the hardware brand if visible and a short history of when the trouble began. Do not remove the lock to find a model number.
In a rental, report the problem to your landlord or property manager before making repairs. Building rules and local requirements vary.
Work through the checks
- 01
Identify what fails to stay closed
Distinguish the spring latch moved by the knob or lever from a separate deadbolt. This guide addresses the door popping open after closure. A hard-to-turn deadbolt has its own related guide below.
- 02
Observe the handle with the door safely open
Operate the unlocked handle normally once. Note whether the latch retracts and returns when released. If the handle droops, sticks or fails to return, record that without dismantling the mechanism. Keep the route clear so no one becomes trapped, and arrange service.
- 03
Look for an ordinary obstruction
Check for a displaced mat or an item in the swing path. Note new weatherstripping or a fresh finish that changed the fit. Move a loose household obstruction only when safe; do not strip seals or alter a closer.
- 04
Watch one gentle approach to the frame
Only if safe to do so, bring the door toward its closed position without lifting or slamming it. Note whether it rubs before reaching the strike or whether the latch appears above, below or beside the opening. Do not shut yourself into a room to test it.
- 05
Record changes around the door
Photograph visible gaps, loose-looking hardware and existing rub marks. Note recent installation, weatherstripping or a seasonal pattern. These clues help a repairer; they do not establish that the house has shifted or that a hinge must be replaced.
- 06
Choose the appropriate repair contact
Give the observations to the landlord, hardware manufacturer or qualified door technician. Adjustment depends on the door and lock design. Avoid filing the strike, chiseling the frame, bending parts or adding random lubricant before the cause is established.
What your result means
These observations help choose a next step. They do not confirm a diagnosis.
| What you notice | What it tells you | Next step |
|---|---|---|
| Latch moves with the door open but misses the strike | Fit or alignment needs assessment | Record the contact point for the repairer; do not force closure. |
| Latch or handle sticks while away from the frame | Hardware operation also needs attention | Contact the manufacturer or qualified service before changing the strike. |
| Door rubs before the latch reaches the frame | The door fit is part of the observation | Note the rubbing edge and recent changes. |
| A loose mat obstructs the swing | There is an ordinary obstacle | Move it clear if safe; confirm normal closure without altering the door. |
| A required self-closing door does not latch | Fire protection may be impaired | Report it promptly; do not tape the latch or disable the closer. |
Know what happens next
Check the outcome
After authorized repair, check that the door closes and latches with ordinary use and opens normally from the occupied side. Ask the technician to demonstrate any self-closing or fire-door function. Needing a lift, hard push or slam means the result still needs attention.
When to call a professional
Stop for a loose or damaged door, broken glass, failing hinge, a person at risk of being trapped, or an exit that cannot be used safely. Security, apartment entrance and fire-door defects need prompt service. Renters should report the condition before altering hardware.
Take useful notes with you
A short record makes it easier to explain the problem to a landlord, technician, or responder. Do not collect notes during an emergency.

Common questions
Should I file the hole larger?
Not before the cause is known. Enlarging a strike opening does not correct every alignment or hardware problem and changes the door assembly.
Does a drooping lever mean the whole door is sagging?
No. Schlage identifies an internal chassis issue as a possible reason for its drooping handles and directs users to support. Describe handle movement separately from the door fit.
Can I tape the latch so the door stops catching?
Do not bypass the latch, especially on a self-closing or fire door. Report the problem and have the correct function restored.
