How to Break a Door Lock from the Outside: You can use a credit card, a screwdriver, or a bobby pin to break a door lock from the outside.


Door locks are designed to provide us with privacy and security, but unfortunately, they can also be a source of frustration. In some cases, a door lock may malfunction or become stuck due to age or damage, making unlocking it from the outside impossible without breaking the lock. Knowing how to break a door lock from the outside without damaging the door itself can save you plenty of time and money on repairs. If you are ever in this situation, follow the steps outlined below for peace of mind and successful entry into your home or other secured area.

Tools Needed

Breaking into a door lock requires the right tools. Depending on the type of lock, you’ll need to have the right kind of tool to pick it or Break Open it. Some of the tools needed for this task may include a drill, an awl, a tension wrench, a rake, and a screwdriver. In the following section, we’ll discuss these tools and what they do to help you Break Open locks.

Lock pick set

A lock pick set is a collection of tools designed to help you open a locked door. It includes a variety of picks, tension wrenches, and other specialized tools. They come in different sizes and shapes, so it’s important to find one that fits the type of lock you’re trying to pick.

Using a lock pick set is typically the fastest way to open a door lock from the outside. This is because it allows you to bypass the internal tumblers by manipulating them with precision tools rather than relying on brute force.

To use a lock pick set, you will need some basic knowledge of locks and how they operate. The first step is to insert your tension wrench into the bottom or side of the lock keyhole and apply gentle pressure in the direction that you want the lock cylinder to turn (usually counterclockwise). Then use various picks included in your set (rake, hook, half diamond etc.) to manipulate individual pins inside the cylinder until all pins are raised and allow for full cylinder rotation. This will free up the locking mechanism and allow you access.

Bump key

A bump key is an essential tool for breaking a door lock from the outside. A bump key is a modified key that can successfully insert into any lock, even if it is not the correct key. To create a bump key, you will need a blank key of the same type and brand as the lock that you want to open. The blank must have all the correct cuts for that specific brand and model of lock.

Once you have found a matching blank, you will need to file off the ridges at the peaks of each cut in order for it to work properly. When filing, you should make sure to keep track of which ridges were filed off so when using your bump key, you can accurately identify which ones should be struck with an appropriate tool such as a hammer or mallet. Once your bump key has been modified properly, it should be able to open any door lock from outside without difficulty given enough force and accuracy in striking it.

Lock picking gun

One of the most reliable tools for Breaking Open a door lock from the outside is a lock picking gun. This thin metal device has two ends: one with a trigger, and the other pointed. The pointed end is inserted into the keyhole and triggers the pins inside the lock, allowing it to open without damaging the lock itself.

It’s important to read up on how to properly use a lock picking gun before attempting to Break Open your door-these devices are quick and easy to use, but must be used correctly in order to work effectively and avoid potential damage. You can purchase an affordable lock picking gun online or at most hardware stores, and they come in various sizes for different types of locks-make sure to check before making your purchase so that it’s compatible with your specific Breaking Open needs.


Breaking a door lock from the outside can be a difficult task, but it is possible if you have the right tools and know-how. In this section, we will be exploring some of the techniques that can be used to break a door lock from the outside. These techniques range from using a rake or tension wrench to using a crowbar or drill. We will also discuss the pros and cons of each method.

Lock picking

The art of lock picking involves using tools to manipulate the pins or wafers in the lock cylinder. Although many locks are designed to resist picking, an experienced locksmith can usually overcome these features. Lock picking requires one or more special tools such as a tension wrench, pick gun, bump keys or rake picks.

When starting out, it’s a good idea to practice on an old padlock or door knob lock until you’re comfortable with how to use the tools and understand how they interact with the lock mechanism. Proper technique is incredibly important, as too much force can permanently damage the lock housing. Once you understand the basics of how a pin-and-tumbler and wafer system work in traditional locks – getting a feel for where things go wrong and why – you will have more success when attempting more difficult jobs.

There are several methods you can use when attempting to pick a locked door from the outside:
-Raking: Using a rake pick consists of inserting it into the keyhole and attempting to push up all pins in rapid succession by dragging it across them.
-Single Pin Picking (SPP): This involves carefully inserting each tool one by one while applying light tension until each pin is set.
-Bump Key Method: A bump key is created to mimic any specific key in order for it to fit into its own respective lock cylinders. To this end, it allows anyone with access to such keys bypass any physical obstructions directly present within any applicable locks’ cylinders without even having direct physical access inside any countermeasures applied against unauthorized entry into any applicable secure area.


Bumping is one commonly used technique for breaking a door lock from the outside. It entails using a specialized bump key that works by repeatedly striking the lock pins into their shear line which then causes them to jam, releasing the lock. To perform this technique, you’ll need a bump key, wax or putty knife, and hammer. Firstly, insert the appropriately sized bump key into the lock cylinder and use the wax/putty knife to carefully hold it in place. Then strike it lightly with the hammer for several strikes until you feel a slight give in the mechanism. Finally, turn your key and press down firmly until you hear an audible click indicating that your door has unlocked. Be aware that due to the unpredictability of how locks can react to different attempts at entry, success cannot be guaranteed when attempting this tactic so please proceed with caution.

Lock picking gun

One effective technique for breaking a door lock from the outside is using a lock picking gun, sometimes simply referred to as a snap gun. This tool is designed to quickly and easily pick locks without necessarily understanding how to do so. It involves inserting the tip into the keyhole of the lock and rapidly activating it, creating pressure that forces the pins inside up and out of place, allowing you to open the door.

When using a lock picking gun, make sure you have ear protection as they create loud noises when activated. Additionally, it takes some practice in order to become familiar with the device, so take your time when operating it if you’re not completely sure of what you’re doing. Finally, be careful not to apply too much pressure on the device or you risk damaging whatever you are trying to break in to.


Breaking a door lock from the outside carries with it a number of safety risks. For example, there is a risk of doing damage to a door and the lock, as well as a potential risk of injury if you are not careful. Furthermore, if the door lock is connected to an alarm system, breaking it could set off the alarm and draw unwanted attention. It is important to be aware of the potential risks and take necessary precautions before attempting to break a door lock.

Wear gloves

Whenever you are dealing with locks, it is important to wear protective gloves such as gardening or work gloves. This will protect your hands from abrasions and scratches that can occur from using the tools involved in this procedure. It is also a good idea to wear gloves any time you are working with locks in order to keep fingerprints off of the parts that could be helpful in identifying thieves.

Use caution

When attempting to break a door lock from the outside, it is important to use caution and take into consideration the legal implications of doing so. If someone is locked inside a home or building, forcing open the door from outside can be a very dangerous and potentially life-threatening situation. Before attempting to break down a door or even pick the lock, it is important to consider all other options. You may be able to contact the owners or authorities quickly and safely, without any damage being caused in the process. It is also possible that authorities can gain access without immediately removing the lock altogether.

If none of these potential solutions are effective and you must forcibly break open a lock, ensure you are taking all necessary safety precautions and following relevant legal procedures prior to commencement of any job. The type of door lock you are attempting to break will determine how best to approach this task: whether by using specialized tools such as crowbars, wedges or chisels; drilling through; cutting with bolt cutters; vibrating with an oscillating tool such as an Air Chisel; freezing with compressed air; or electro-picking with voltage surge. Whatever tools you decide to use for this job, make sure they’re approved for this type of work and only used by qualified individuals trained in proper safe practice for handling dangerous tools.


Breaking a door lock from the outside is a complex task that requires both knowledge of the lock and tools. It should never be attempted unless you have a valid reason for doing so, such as rescuing a person trapped inside or gaining access to your own property in an emergency.

The best way to break a door lock from the outside is by employing special force along with specialized tools. This should only be done after making sure all other possible solutions, such as key duplication or picking the lock, are not available. If you do attempt to force open the door, be sure to exercise extreme caution and use effective strategies. It is also important to be aware that using unauthorized methods of lock breaking can land you in legal trouble due to vandalism or trespassing laws.

Making sure all other options are exhausted before attempting to break a door lock from the outside is essential for avoiding any legal trouble while also safeguarding yourself against any physical risks involved in breaking locks without proper precautions.
