Types of Door Locks

When trying to break open a door lock without a key, it’s important to understand what type of lock you are dealing with. There are numerous different types of door locks and each type requires different methods to open without a key. Understanding the types of locks, as well as their strengths and weaknesses, can help you decide which technique is best for your specific situation.


Deadbolts are heavy-duty locks that are bolted into the door frame and provide an extra layer of security over regular doorknobs. Deadbolt locks can be used in residential, commercial and institutional settings depending on their construction. Traditional deadbolts come with a keyhole entry system, while more technologically advanced types come with keypads, RFID cards or biometric readers. Generally, deadbolts are single-cylinder models where a key is used to unlock the door from the exterior. But there are also double-cylinder deadbolts that require a key or code both from the inside and outside in order to operate.

Traditional deadbolt locks use a five or six pin tumbler system inside an elongated cylinder for added security, so these types of locks require picks of appropriate sizes to reset them when lost keys or forgotten codes occur. There are also other lock designs such as surface mounted slammers, jimmy proofs, reversible latches and mortise locks that do not need picks at all; they can be opened using only straightened paper clips through their thumb turn mechanisms on one side of the door without any need for keys whatsoever.

Knob Locks

Knob locks are commonly used on homes and businesses and are relatively easy to pick or force open with a wide variety of tools. Knob locks have an inner knob that requires a key to turn and an outer knob, which is used to open the door. This type of lock may also be referred to as a cylinder lock, due to its cylindrical shape.
When selecting a knob lock for your home, be sure to choose one with a high security rating that can withstand forced entry attempts. Some common types of knob locks include:
-Tubular Knob Lock: tubular locks are characterized by their cylindrical shape, as well as their unique keyway design.
-Mortise Knob Lock: mortise locks are much more secure than traditional knob locks and require more complex installation methods in order to fully secure them against forced entry attempts.
-Deadbolt Lock: deadbolts provide added security because they require the use of two different keys in order to unlock the door, making it much more difficult for intruders to gain entry without force.
-Combination Deadbolt Lock: combination deadbolts provide added convenience since they allow you to set your own personal code instead of relying on physical keys or mechanical locking mechanisms.

Lever Handle Locks

Lever handle locks are a popular choice for both residential and commercial buildings due to their ease of installation and operation. They can be used on doors that swing in or out, and feature two latch bolts – one located at the top of the door for security, and another located at the bottom for convenience. Lever handle locks work via a key or thumb-turn from either side of the door. When locked from the inside, both latches will be engaged – with the top latch requiring a key or thumb-turn to disengage. From the outside, only one latch needs to be disengaged with a key while pushing down on the lever handle will release the other one.

Popular lever handle locks include those made by Ardwolf, Schlage, Yale and Kwikset. All these brands come in a variety of finishes and have different levels of security ranging from basic to high-security models featuring deadbolts with interchangeable cores or other more advanced features. Lever handle locks are available in single cylindrical varieties suitable for commercial use as well as mortise models ideal for residential applications.

Breaking Open a Deadbolt Lock

Breaking open a deadbolt lock without a key is possible, but it requires skill, patience and specialized tools. There are a few different methods that can be used, each offering slightly different levels of success. In this section, we will explore how to break open a deadbolt lock using a drill bit and other tools. We will cover the pros and cons of each method, as well as the materials and tools you’ll need.

Insert a tension wrench into the keyhole

Inserting a tension wrench into the lock is the first step in breaking open a deadbolt lock without using a key. A tension wrench is a small “L” shaped metal device that is inserted into the keyhole to provide tension and rotation when turning a lock. You’ll want to choose one with an appropriate tip size that fits into your deadbolt’s keyhole snugly, but still allows you to turn it with ease. Keep in mind that thicker keys might require two wrenches, while thinner keys might need only one. Once the tension wrench is inserted all the way into the lock, twist it counter-clockwise until you feel lateral pressure or resistance on your exteriorside of the door. This indicates that the pins inside have aligned correctly and are allowing you access to turn the cylinder should you have used a key with opposite turns.

Next, insert your short hook pick-a small tool made of wire-into the locks keyway and push down towards the bottom pin stacks inside. Right away try gently rocking this short hook pick from side to side in order to “feel” when you’re accidentally placing any pin too far above its set point within yourlock cylinder; When this happens use moderate pressure up as opposed as downto move them back down as necessary, while keeping your tension onthe wrench throughout all this either clockwise or counterclockwise depending on which direction you’ve chosen earlier to work with. With enough finesse and patience, each pin should eventually release in order allowing access toturningthe latch bolt once again at any moment.

Insert a pick into the keyhole

Insert a pick into the keyhole and use the pick to lift up all the pins in the lock until they are all lifted. Insert a tension wrench into the keyhole and turn it slightly in both directions, repeating as necessary to make sure all pins are as high as you can make them. If done correctly, this will release the lock’s cylinder so you can turn it. Be sure not to apply too much pressure, as this may cause damage to your lock. If necessary, turn your tension wrench more firmly, but with incremental turns until it no longer requires more force.

Manipulate the pick to turn the lock

When learning how to break open a deadbolt lock without a key, you first need the right tool set. You will need a tension wrench and a pick. The tension wrench is used to turn the lock; the pick will help to move the pins in the cylinder so that it can turn. Once you have inserted your tension wrench into the keyhole of the deadbolt, manipulate your pick with steady pressure and small movements so that it fits in between each of the pins. As you place pressure on one side of each pin, lift slightly until they are raised enough for them to slide out of their chambers and unlock. As this occurs, use your tension wrench to begin turning the lock gently in a clockwise or counterclockwise direction (depending on type) until it is unlocked.

Breaking Open a Knob Lock

Knob locks can be one of the easiest door locks to break open without a key. This type of lock uses a spring-loaded latch and does not require a key to open the door.

The catch is most likely located where the top part of the key would be, just above or slightly below the middle of the knob. When you feel or hear a click, this indicates that you have released parts of the lock and can now remove it from its housing. Apply pressure while gently turning in both directions at once to remove it.

Use the screwdriver to turn the lock

For most door locks, the next step for breaking open a knob lock is to insert a flat-head screwdriver into the keyhole and attempt to manually turn the lock clockwise or counter-clockwise until it releases. The resistance from the defeated locking mechanism might require substantial force, in that case you may want to use a locking wrench and/or an adjustable wrench, especially if there is rust or corrosion buildup in the area of the locking mechanism inside the doorknob. To prevent further damage of your doorknob or other unintended collateral damage, use two quick twists with one hand on either end of your screwdriver or wrenches when applying force-this will evenly disperse stress along all surfaces. For additional assistance you can use metal lubricants like WD-40 to prevent rusting and make it easier turning the knob with your implement(s).
