How to Pick a Door Lock - Doorknob Handle Deadbolt

Key Takeaways

Most common residential door locks use a pin-tumbler mechanism. For these, a tension wrench and a pick are the two tools you need to open a doorknob lock, lever handle lock, or deadbolt.

Only attempt on property you own or have explicit permission to access
Insert a tension wrench into the keyhole and apply light rotational pressure in the key-turning direction
Use a pick to lift each pin to the shear line; hold tension to keep each set pin in place
Applies to doorknob locks, lever handle locks, and deadbolts
If a lock says it "needs a key," it uses a standard pin-tumbler design — the same tension-and-pick approach applies

Learning how to pick a door lock can be a valuable skill, whether you're dealing with a lost key or exploring the mechanics behind lock security. This comprehensive guide will walk you through everything you need to know about lock picking. We'll start with the basics of locks, delve into the different types of locks and the steps to pick them, and cover the various lock picks and their uses. With this knowledge, you'll be well-equipped to handle common lock situations and understand the intricacies of different locking mechanisms. Let's dive in and demystify the art of lock picking!

Note: Picking someone else's lock without authorization may constitute trespassing or breaking and entering. For high-security or electronic locks, or when in doubt, contact a licensed locksmith.

Learn the Basics of Locks

Understanding how a lock works makes picking it more predictable. Most standard door locks share five core components:

Keyway: The slot where the key (or pick) enters; its shape determines what tools will fit.
Plug (core): The cylindrical part that rotates when the correct key is used, retracting the latch or bolt.
Key pins and driver pins: Pairs of pins stacked above each other that must align at the shear line to allow the plug to turn.
Shear line: The boundary between the plug and the outer housing; when all pins sit at this line simultaneously, the lock opens.
Springs: Push the driver pins back into their default (locked) position whenever no key or pick is applying upward pressure.

Types of Door Locks and How to Pick Them

Understanding the different types of door locks can help you choose the right security solution for your needs. Here are the most common types of door locks and the methods on how to pick a lock on a door:

Lock Type	Applicable Scenarios	Core Features	Lock-Picking Methods
Deadbolt Locks	Exterior doors	High security; a solid metal bolt extends into the door frame via key/thumb turn, providing strong resistance against forced entry	See the How to Pick a Deadbolt Lock section below for step-by-step instructions.
Knob Locks	Interior doors	Convenient for indoor use; key cylinder built into the knob; less secure than deadbolts as the mechanism is easier to bypass or break	Same as deadbolt locks: apply tension with a wrench + lift pins with a pick until the lock turns.
Lever Handle Locks	Interior doors; areas requiring accessibility	Easier to operate than knob locks, ideal for people with limited hand strength/dexterity; equipped with a lever handle and latch mechanism	1. Insert a tension wrench and apply light rotational pressure in the key-turning direction (not the lever's downward direction). 2. Use a pick to lift the internal pins until the lever moves and unlocks the door.
Cam Locks	Cabinets, mailboxes, small enclosures	Simple to use and install; moderate security; unlocks by rotating a cam with a key	1. Insert a small flathead screwdriver or pick into the keyhole. 2. Gently rotate the cam mechanism until the lock unlocks.
Rim Locks	Older or decorative doors	Surface-mounted (not recessed); interior latch + exterior key cylinder; used as a secondary security measure	1. Use a tension wrench and pick: apply tension with the wrench + manipulate pins with the pick until the lock turns. 2. Alternative: use rim lock-specific bypass tools.
Mortise Locks	Commercial properties, older homes	Installed in a mortise cut into the door edge; durable and high-security; complex mechanism with deadbolt and latch	1. Insert a specialized tension wrench into the keyhole and apply slight pressure in the key-turning direction. 2. Use a pick to lift the internal pins carefully (due to the complex mechanism). 3. The lock turns to unlock once all pins are set.
Padlocks	Gates, sheds, storage units	Portable; keyed or combination-operated; not permanently attached; versatile	1. Traditional method: tension wrench + pick (same steps as deadbolts). 2. Alternative: slide a shim between the shackle and lock body to release the mechanism.
Cylinder Locks	Residential and commercial buildings	Easy to rekey or replace without changing the entire mechanism; available in euro/oval cylinder types	1. Insert a tension wrench into the keyhole bottom and apply pressure in the key-turning direction. 2. Insert a pick and lift pins one by one while maintaining tension. 3. The lock turns to unlock once all pins are set.
Interconnected Locks	Exterior doors (for emergency exit)	Combines deadbolt and latch; both can be operated simultaneously from the inside with one lever/knob turn; enables quick exit	1. Insert a tension wrench into the main keyhole and apply pressure in the key-turning direction. 2. Requires professional locksmith tools and advanced knowledge to manipulate multiple locking points due to its complexity.
Multi-point Locks	Patio doors, French doors, high-security exterior doors	Secures doors at 3-5 points along the frame with one key turn; highly resistant to forced entry	Highly complex; cannot be picked like single-point locks; professional locksmith tools and techniques are required.
Barrel Bolt Locks	Interior doors; additional security for exterior doors	Also called sliding bolt locks; a metal bar slides into a catch; used as a secondary lock	Cannot be picked traditionally (manually operated from the inside). If accessible, slide the bolt open with a thin tool through the door gap.
Chain Locks	Residential front doors	Secondary security; allows the door to open slightly while locked; enables checking visitors without full door opening	Cannot be picked traditionally. Bypass by maneuvering the chain off its track with a thin tool if there is enough space.
Smart Locks	Residential and commercial buildings; smart home systems	High-tech; supports Bluetooth/Wi-Fi/keypad/biometric (e.g., fingerprint) entry; remote access, monitoring, and home automation integration; high security + convenience	1. Check for a manual key override: use traditional picking methods on the key cylinder if available. 2. Electronic bypass: requires hacking the digital system or exploiting software vulnerabilities (not recommended without authorization). 3. Alternative: use physical bypass tools.

How to pick a doorknob lock

Most interior and exterior doorknob locks use a standard pin-tumbler mechanism, making them approachable for anyone who needs to get back into their own home. Only attempt this on property you own or have explicit permission to access.

Insert a tension wrench into the bottom of the keyhole. Apply light, steady rotational pressure in the direction the key would turn; too much pressure will bind the pins and prevent setting.
Insert a hook pick (or rake pick) above the tension wrench. Gently lift each pin one at a time while maintaining steady tension on the wrench.
When a pin reaches the shear line, you will feel a slight give or click, and the plug will rotate fractionally; hold tension to keep that pin set.
Repeat for each remaining pin until all are set at the shear line.
Once all pins are set, the plug turns freely and the latch retracts.

If the lock description says it "needs a key," this is the same pin-tumbler process; no special tool is required beyond a tension wrench and a pick. If the knob feels stuck, do not force it. Back off your tension and start over.

How to pick a door handle (lever) lock

Lever handle locks share the same pin-tumbler internals as knob locks. The key difference is that the lever travels downward rather than rotating, and the keyway is often positioned at a slightly different angle.

Insert a tension wrench into the keyhole and apply light rotational pressure in the key-turning direction. Try both directions and use the one with slightly more resistance (the binding direction).
Insert a hook pick above the tension wrench. Lever lock keyways are often wider than knob locks, giving you more room to maneuver.
Lift each pin individually to the shear line while maintaining steady tension. You will feel each pin set with a slight give.
Once all pins are set at the shear line, the lever mechanism releases and the door opens.

The internal pin-setting technique is identical to doorknob picking; only the keyway angle and your grip on the tension wrench may need slight adjustment.

How to pick a deadbolt lock

Insert a tension wrench into the bottom of the keyhole and apply light rotational pressure in the key-turning direction.
Insert a hook pick and lift the pins one at a time while maintaining steady tension. Deadbolts often have tighter tolerances than knob locks; use minimal pressure to avoid binding the pins.
Once all pins are set at the shear line, the cylinder turns and the deadbolt retracts.

Unlike a spring latch, a deadbolt has no spring-loaded bolt; it cannot be shimmed or slipped with a card.

Before You Pick: Legality, Difficulty, and When to Call a Locksmith

Legal Disclaimer: Picking locks without permission is illegal and considered trespassing. These techniques are shared for educational purposes or for situations where you have legal access to the property, such as losing your keys.
Skill Level: Lock picking requires practice and skill. Some locks are easier to pick than others, and specialized tools might be necessary for certain types.
Professional Help: For complex locks like mortise or multi-point locks, or in situations where traditional picking methods do not work, it is best to contact a professional locksmith. If the lock feels unusually resistant or you are not making progress after several attempts, stop and call a licensed locksmith.

Always ensure you have legal permission to pick a lock, and use these techniques responsibly. If you find yourself picking locks more often than you would like, a smart lock removes the problem at the source.

The eufy Video Smart Lock S330 supports five ways to unlock: fingerprint, the eufy Security app, Alexa or Google voice, keypad, or physical key. The Smart Lock S230 covers four: fingerprint, app, keypad, or key. Either option reduces daily lock fumbles while keeping a backup physical key on hand for emergencies.

Types of Lock Picks and Where to Use Them

Lock picking requires the right tool for the job. Here is a quick guide to the five most common types of lock picks and where each one fits:

Hook Pick: for pin-tumbler locks; lift one pin at a time to the shear line.
Rake Pick: for pin-tumbler and wafer locks; scrub or rock to set multiple pins at once.
Tension Wrench: for all pin-tumbler locks; applies rotational pressure to hold set pins at the shear line.
Skeleton Key: for warded locks; bypasses the ward plates to engage the turning mechanism.
Disc Detainer Pick: for high-security disc detainer locks; rotates each disc to the open position.

Conclusion

Lock picking is a practical skill, but only a legal one when used on property you own or with explicit permission. In those situations, the fundamentals are consistent: a tension wrench, a pick, and the shear line principle will get you through doorknob locks, lever handles, and deadbolts alike. For anything beyond that, a licensed locksmith is the smarter and safer choice or a eufy smart lock if you'd rather not rely on keys at all.

FAQs

What Locks Cannot Be Picked?

Disc detainer locks can be opened with a specialized disc detainer pick, but mid-to-high-tier models require precision tools and considerable practice; success rates drop significantly with higher-security models. Fully keyless electronic locks have no keyway, so traditional picking tools have no entry point; if you are locked out, follow the manufacturer's reset process or contact a licensed locksmith.

How Hard Is It to Pick a Lock?

The difficulty of picking a lock depends on the type of lock and the skill level of the picker. Basic locks can be picked relatively easily with practice, while high-security locks require more expertise and specialized tools.

What Are the Legal Implications of Picking Someone Else's Lock?

Picking a lock without permission is illegal and considered breaking and entering. It can lead to serious legal consequences, including fines and imprisonment. Always use lock picking responsibly and ethically.

Can You Tell If a Lock Has Been Picked?

Yes, signs of lock picking include tiny scratches around the keyhole, misalignment of internal pins, and unusual looseness in the plug. A picked lock may also feel easier to turn. In some cases, lock wafers or pins might be slightly damaged. Forensic locksmiths can examine these details more closely to confirm if tampering has occurred.

What Household Items Can You Pick a Door Lock With?

In a legitimate emergency, such as being locked out of your own home, common household items can substitute for proper picks. Paperclips, bobby pins, and safety pins can be shaped into a tension wrench and pick. Aluminum strips or small flathead screwdrivers may also work. In some cases, a plastic card can slip a spring latch. These methods work best on simple locks and should only be used responsibly on property you own or have permission to access.

How Do You Pick a Bedroom Door Lock?

Most bedroom doors use an interior privacy knob or button lock, not a keyed deadbolt, which makes them easier to open without standard picks.

Check for an emergency access hole first. Look for a small pinhole or slot on the outside of the knob. Insert a straightened paperclip or thin nail straight in and push lightly; the privacy mechanism releases immediately with no picks needed.
If the knob has a keyway and no emergency hole, follow the standard doorknob picking steps: insert a tension wrench and apply light pressure, then use a pick to lift each pin to the shear line. See the How to pick a doorknob lock section above.

Only attempt this on your own bedroom door or with the occupant's permission. If the lock is stuck, do not force or pry the door, frame, or hinges. Call a locksmith if standard techniques do not work.
