How to Break Into a Screen Door Lock


Learning how to break into a screen door lock can come in handy when you’re locked out of your home or when you need to replace a broken or damaged lock. Screen door locks are typically installed on exterior doors and while they are designed to provide an added layer of security, they can become worn down over time leading to corrosion or breakage. If this happens, you may be able to break into the screen door without having to replace the entire lock. While there are many ways in which you can open a lock without using a key, some methods are more effective than others – and some may even cause permanent damage. Before attempting any of these techniques, proceed with caution and determine which will be the best option for your particular situation.

Tools Needed

Breaking into a screen door lock can be done with the right tools and a bit of patience. The basic tools you will need to break into the lock include a screwdriver and a pair of pliers. You may also need a flathead screwdriver, depending on the type of lock. Before attempting to break into the lock, make sure you have all of the necessary tools at your disposal. With the right tools in hand, you will be able to break into a screen door lock with ease.


A screwdriver is a hand tool used for turning screws in and out. Depending on the job, you may need several different types of screwdrivers. For breaking into a screen door lock, you will need a Phillips-head screwdriver. This type of screwdriver has an X-shaped tip that fits into the slots on a Phillips-head screw. It is important to use the right size driver for the job; if it’s too small, it won’t fit properly into the slot, and if it’s too big, it can strip or damage the slots in the screws.

Flat-head screwdrivers are also used in this process and may be needed to remove other components from around the lock before using a Phillips-head driver to dismantle its internal parts. If possible, try to find one with interchangeable bits so you don’t have to carry around multiple tools for various types of screws.


Pliers are a versatile tool commonly used in many do-it-yourself projects. In the context of lock picking, they are usually needed to grip and pull out the broken key pieces, as well as loosen and loosen any screws or pins that may be part of the lock mechanism. To effectively use pliers as part of a screen door lock breakout, you will need a pair of long nose pliers or diagonal cutters. Long nose pliers have an elongated body that allows you to better reach into tight spaces while diagonal cutters have their blades angled at 45 degrees which give them greater biting power on round objects such as pins. Both tools can be adapted for various lock picking tasks and offer a great deal of precision compared to using larger tools like hammer and chisels.


A hammer is one of the more basic tools that you will need when attempting to break into a screen door lock. Choose one that is heavy enough to apply enough force, but not so heavy that it could damage the lock mechanism. A claw hammer can be helpful for prying open locked doors and for driving out pins in padlocks, shackle locks and combination locks. Its long handle helps to provide leverage in these circumstances, making work easier and helping you remain safe during the process. Make sure the head of your hammer is firmly attached to its handle – any loose connections could cause injury during use.


Breaking into a screen door lock can be a tricky task. However, with the right tools and techniques, it can be possible. Many locks can be picked, while others can be bypassed with a credit card. In this article, we will cover the steps that you need to take in order to successfully break into a screen door lock.

Remove the screws from the outside of the door

Removing the screws from the outer housing of the lock is the first step in attempting to break into a screen door lock. To do this, use a suitable screwdriver that fits the head of the screw and unscrew all of the screws until they are removed. Depending on the type of lock used, there may be anywhere from two to four screws on each side. Once all of them are removed, carefully pull on each side of the lock to separate it from its housing in order to access inside component pieces.

Insert a flathead screwdriver into the lock

Insert a flathead screwdriver into the top of the lock. If the mechanism has more than two pins to turn, use one finger to hold in each pin and turn the screwdriver. The handle should be pushed down, allowing you to feel if each pin has been sprung. If it has been sprung, rotate the flathead screwdriver until it clicks and goes back into its original position. Keep repeating this process until all of the pins are set in place. When all of them have been secured, the lock should open. Be sure to securely hold onto the handle before removing your hand from the lock cylinder because if it’s not secure all of your efforts will have been for nothing!

Pry the lock open using a pair of pliers

Using a pair of pliers, you can apply enough concentrated pressure to the head of the lock cylinder that it pops off the frame. This can cause significant damage to the door and may not be effective if a strong adhesive has been used, so use with caution. First, determine which direction needs to be turned in order to unlock the screen door. Next, grab your pair of pliers and make sure they are firmly attached to the cylinder head. Finally, twist gently until you hear a “pop” from the cylinder head being removed from its frame. If this method does not work or if there is significant resistance at any point during the process, stop immediately and consult professional assistance before proceeding further.

Hammer the lock open

Picking the lock on a screen door may not always be an option, but there is a way to Break Open the lock with a hammer. This should only be used as a last resort, as it can permanently damage the lock. In order to Break Open the lock with a hammer, you will need the following tools and supplies:

The force of impact will usually cause enough damage to Break Open and disable the lock without destroying its keyway in case you simply misplaced or lost your keys.
3. You can also use an alternative method such as heating up or melting your spark lighter and placing it over each side of then keyed entry on top side where there are no pins located in order for it to completely unglue (this completes evaporates) any glue or industrial bond which may be holding your locks casing together that holds security pins inside from falling out onto your hands! This technique is especially useful on newer model locks since most have plastic or metal shells that are glued together unlike traditional locks which would have screws holding casing halves apart for repairs or access by professionals!
