Most interior bedroom and bathroom door knobs are “privacy” locks that can be unlocked from outside without a key. Look for a small hole in the center of the outside knob, insert a thin tool (the emergency key, a small flathead screwdriver, or a straightened paperclip), and either push straight in or turn it until the lock releases. This works only on privacy locks—front doors and keyed locks need the key or a locksmith.
Identify the Type of Lock
| Outside of the knob | Lock type | How to open |
|---|---|---|
| Small round hole | Push-button privacy lock | Push a thin pin straight in |
| Small slot | Turn-button privacy lock | Insert a flat tool and turn |
| Keyhole | Keyed lock | Use the key or call a locksmith |
| Nothing | Passage knob (no lock) | The door may be stuck, not locked |
Method 1: Push-Button Lock (Round Hole)
- Straighten a paperclip or use the thin emergency key that came with the knob.
- Push it straight into the hole until you feel resistance.
- Push firmly—you should feel or hear a click as the button pops out.
- Turn the knob and open the door.
Method 2: Turn-Button Lock (Slot)
- Insert a very small flathead screwdriver or the emergency key into the hole.
- Feel around until it seats into a slot.
- Turn clockwise or counterclockwise until it stops, then try the knob.
Method 3: The Credit Card Trick
On doors with a spring latch (and no deadbolt), slide a flexible plastic card between the door and frame at the latch, angle it toward the latch’s sloped side, and wiggle while pushing on the door. It works best on doors that open away from you. It can scratch paint and won’t work on deadbolts.
Method 4: Remove the Hinge Pins
If the hinges are on your side, tap the hinge pins up and out with a screwdriver and hammer, then lift the door off. Reinstall afterward.
Keep an Emergency Key Handy
Many privacy knobs come with a small metal emergency key. Keep it on top of the door frame or in a kitchen drawer so it’s ready when needed.
Paperclip vs Emergency Key

- No damage to the door or knob
Cons
