Mastering the skill of opening a lock without a key is incredibly useful, especially when you've misplaced or forgotten your key. With just a few basic tools and some patience, you can unlock almost any type of pin tumbler lock, making it possible to handle everything from door locks to padlocks.
Steps
Prepare the lock before attempting to open it

Assess the condition of the lock. You won’t be able to unlock it if it’s broken. A rusted lock can become jammed no matter how skilled you are at picking. Check the overall state of the lock before trying to pick it.
- A rusted lock can often be revived and made workable by applying a lubricant, such as WD40.

Prepare the lock-picking tools. The lock-picking set includes tools such as a tension wrench, a pick, and a rake. You will also need a suitable lubricant like graphite powder, which can be purchased at hardware stores.
- You can use household items as substitutes for lock-picking tools, like hairpins or paperclips.
- You may need to visit specialized stores, such as spy shops, locksmith shops, or online stores, to purchase a lock-picking set.
- While most regions allow the purchase of lock-picking tools, you might need to prove your intentions are not criminal if you are caught carrying them.

Understand the purpose of the three main lock-picking tools. Knowing the function and names of basic lock-picking tools helps you communicate better. This is crucial because pop culture has often misnamed some of these tools. The three main tools are:
- Tension wrench. This tool is used to apply rotational pressure and is a thin metal bar with two flared ends. The tension wrench is usually L-shaped or Z-shaped, with the diagonal side of the Z being straight. It is inserted into the lock’s core (the rotating part) to apply pressure.
- Lock pick. A lock pick typically has a handle and tapers into a sharp metal point, with the head often being slightly curved. It is used to manipulate the internal components (pins) of the lock mechanism.
- Rake tool. Similar to a lock pick but with serrated edges. Some rakes have pointed or rounded tips. A rake is used to scrape inside the lock mechanism (scraping pins) to separate them.

Visualize the lock mechanism. When you insert a key into the lock’s core (the rotating part of the lock), the teeth (bumps) of the key push the spring-loaded pins upwards. Each pin consists of a lock pin and a driver pin. When the gap between each lock pin and driver pin aligns with the rotating lock mechanism, the lock will turn and open.
- You cannot see inside the lock when opening it, so visualizing the lock mechanism is essential.
- The number of pins varies depending on the lock. Padlocks typically have 3-4 pins, while door locks may have 5-8 pins.
- Some locks, especially European locks, have the pins located at the end of the core rather than the front.
Lubricate the lock. The pins inside a lock can become stuck due to lack of use. Additionally, dirt and debris can make it harder to manipulate the lock mechanism. Address these issues and apply lubricant to improve the chances of successfully unlocking it.
- Many types of lock lubricants come with a simple spray nozzle that allows you to apply the lubricant directly into the grooves of the lock core.
Unlock a standard pin tumbler lock
Focus on the primary goal of lock-picking. While applying light pressure with the tension wrench on the lock core, you will use the pick to push each pin upwards. When a pin is lifted high enough, the pressure from the tension wrench will keep it from falling back down, allowing you to move on to the next pin. Once all pins are raised, the lock will open.
Determine the key’s turning direction. Insert the tension wrench into either the front or the back of the lock’s core and gently rotate to apply twisting pressure (torque) on the lock cylinder. The cylinder will turn more in one direction than the other. This is the key’s turning direction.
- Be cautious not to apply too much pressure on the tension wrench. While working to lift the pins, you should only use a finger to apply gentle pressure on the wrench.
Probe and inspect the pins with the pick. Insert the pick into the lock’s core. Gently touch each pin with the pick and choose one that can be reached. Apply light pressure and gradually increase the force on the pick until you feel the pin’s spring move upwards. Then, remove the pick.
- Try to visualize the pin you’ve moved in your mind. This will help you track the pins you’ve lifted in case you need to start again.
- By applying increasing pressure on each pin, you can assess the resistance of the pin’s spring. Some pins may be stiffer than others and require more force.
- In general, the internal workings of the lock are relatively delicate. Always use a light touch to avoid damaging the lock or breaking the pick.
Use the tension wrench to apply light pressure to the lock’s core. Insert the tension wrench into either the front or back of the lock’s core and twist gently. Feel for the movement of the lock cylinder. Stop turning the tension wrench. Repeat this process a few times.
- Your goal here is to feel the stiffness of the lock cylinder and locate the position where the pins inside the lock mechanism block the rotation of the core.
Identify the pin that is blocking the lock. Turn the tension wrench to apply light pressure to the lock core again. Insert the pick into the core and gently touch the pins while maintaining pressure on the tension wrench. Stop applying pressure with the wrench. Continue this process until you identify a pin that resists more than the others while keeping light pressure applied. This is the first binding pin.
- Once you find the binding pin, continue to maintain steady pressure with the tension wrench. Too much force will cause the lock to jam, and too little pressure will let the pin fall back down.
Push each pin individually. While maintaining steady pressure with the tension wrench, use the pick to lift the first pin. Gradually, the tension wrench will slightly move the lock cylinder. The first pin is now in place. Use the pick to find the next pin that resists more than the others and lift it. Repeat this process until all the pins are raised.
- With many standard locks, the pins are usually arranged from front to back or vice versa. However, this is not always the case.
- Lift the pins slowly to place them more easily. Once you become skilled, you can work faster, especially when combining it with the scraping technique described below.
- If you apply too much pressure with the tension wrench, the lock will jam. In this case, release the pressure to let the pin fall back and start over.
Unlocking the lock. When the last pin is lifted into position, the lock will completely disengage and open. You may need to apply more force with the tension wrench to turn the lock open. You can also apply a little more pressure with the pick if it’s still in the lock groove, though be cautious not to break the pick.
Using the scraping technique
Use the tension wrench and pick to feel the lock’s internal structure. Typically, you will use the tension wrench to feel the lock’s core. Insert the pick into the lock’s groove and gently tap the pin locations. Press on a pin to test the resistance of its spring.
- Although the scraping technique usually helps experienced lock pickers open locks faster, the principle behind it is to pick each pin individually, and it’s easier for those who are already familiar with pin picking.
Scrape the pins with a scraping tool. You can use either the standard pick or a dedicated scraping tool for this technique. Apply light, steady pressure with the tension wrench on the lock’s core. Slowly and smoothly insert the scraping tool into the lock’s groove. Pull the tool up and sharply jerk it out of the groove.
- When you pull the scraping tool from the groove, only the tool’s tip will apply pressure to the lock’s grooves.
- The scraping tool must be long enough to reach all the pins inside the lock during the scraping process.
Listen for the sound of the pin dropping. You will often need to scrape several times before succeeding. After scraping, stop applying pressure with the tension wrench and listen for a sound from within the lock. The sound of the pin dropping indicates that you are applying the right amount of pressure with the tension wrench.
Pull the scraping tool back and forth along the pins that haven't opened. Scrape the pins as described above. While applying consistent pressure with the tension wrench on the lock’s core, use the tip of the scraping tool to 'scrape' the pins that haven’t yet been opened. If a pin refuses to move, stop applying pressure with the tension wrench and start over. Continue this process until the lock opens.
- If most of the pins remain stuck, you may need to apply more pressure with the tension wrench and slightly increase the scraping force.
Tips
- For very simple locks, such as those used on cash boxes or desk drawers, you may not even need to 'pick'. Simply insert a flat metal object into the lock groove, then turn it clockwise while moving it up and down.
- Smooth the pick tool by filing it to make it easier to slide into the lock groove and manipulate.
- Practice picking inexpensive and simple locks, even older ones that you can find at antique or second-hand stores.
Warnings
- If you do it properly, lock picking shouldn't damage the lock. However, there's always a risk of damaging the lock mechanism.
- In some areas, owning lock picking tools may require proof that you don't intend to break into someone else's property.
- Never apply too much force with the picking tool while attempting to unlock, as it could damage the lock or cause the tool to break.
