With just a few simple steps and some patience, you too can become an expert at opening jammed door locks in no time. Read on for more detailed instructions and information about the tools and techniques we suggest for opening these types of locks.

Tools You Need

Opening a jam door lock without a key can be tricky, so it’s important to make sure you have the right tools. You’ll need a few items to make the process easier, such as a slim jim, a pick tool, and a tension wrench. In this section, we’ll cover the items you need and explain how to use each one to open a jam door lock without a key.


When attempting to open a jam door lock without using a key, the most important tool to have on hand is a screwdriver. Even if the door is old or damaged, it’s possible to unlock it with some basic tools. Depending on the type of lock installed in your door, you may need either a Phillips-head screwdriver or a flat-head screwdriver. More advanced and durable locks may require special tools like extractors or specialized keys that you can purchase from hardware stores and locksmiths.

Phillips-head screwdrivers come in various sizes and can be used to remove screws from the ends of most locks, while flat-head screwdrivers are better suited to removing screws located elsewhere on the lock such as along its sides or center shaft. Once all the screws have been removed, it should be possible to take apart and expose the internal workings of the lock. Be sure to keep all pieces in order so they can be reassembled after unlocking the door. Finally, use a pick or another thin instrument such as an Allen wrench (or sometimes even a paper clip) to manipulate any tumblers inside and turn back any levers that may remain connected inside before sliding out the bolt from its receiving hole in order for the door to open.


Using a paperclip to open a jam door lock without a key is an effective and economical solution. While it may seem intimidating at first, with the proper instructions, you can open your door within minutes.

Before starting, make sure you have the following items: paperclip, needle nose pliers, small wrench or pliers and a flashlight (optional). Additionally, for optimal results be sure to use one long paperclip instead of multiple small ones connected together.

First, straighten out the paperclip so there is no kink in the clip and that it forms a 90 degree angle with one end flattened out. Once it’s shaped correctly, insert the longer part of the clip into keyhole location just above the crossbar. Move it further in until you feel resistance then push up while guiding it to ensure it goes beneath any pins blocking the entryway. Push up until all pins have been lifted above their threshhold level and then turn the clip counterclockwise until you reach unlocking mechanism which will unlock your door instantly.

If this doesn’t work on its own then use needlenose pliers to help push against pins in order to move them up as needed while turning clockwise. Use very little pressure when doing this as too much could lead to damage inside of your door lock system or cause further issues that require professional attention or replacement parts for repair. If problems occur seek professional assistance before trying again at home.


Tweezers are a reliable tool for unlocking jam door locks. Using two pairs of tweezers for leverage, you can open the door without the need for a key. To do this, take one pair of tweezers and insert them into the small hole in the lock. Push in until they reach an opening that is located near the center of the lock mechanism.

With your other pair of tweezers, press down on the tongue or tooth inside that is preventing the lock from opening. You may have to use gentle upward pressure to get it to budge once it’s pressed in as far as possible. It may take some wiggling and jiggling with both pairs of tweezers but eventually you should be able to unlock it. Be mindful not to damage any parts when inserting or pressing down on them with the tweezers.


Pliers can be an effective way to open a jam door lock without a key. To use pliers, ensure that the size of the pliers fits the doorknob. Then, try to remove any caps or covers in order to expose the screw or pins in the doorknob mechanism. Carefully insert the pliers into the opening, and then carefully and slowly pull on them with enough force until you are able to turn or push it open. It is important that you are gentle and patient while doing this, so as not to damage any of the interior components of your jam door lock.


Using a hammer to open a jammed door lock is an effective, albeit destructive, way to gain access. To do this, you will need a hammer, either claw type or straight type; and safety glasses.

First, fit the head of the hammer into any space you find in the lock and gently apply pressure to try and turn it open. If that doesn’t work, use the hammer and strike around the edge of the door knob. Doing so separates the pins in the cylinder from each other, making it possible for you to turn them further with more pressure applied by using the hammer again. Just be careful not to strike too hard so as not to damage your door or break off parts inside your lock mechanism. With a few tries, you should be able to successfully open your bolt without needing a key.

Lock Pick

Lock picking is the practice of unlocking a lock by manipulating the components of the locking mechanism, without use of the original key or knowledge of its corresponding key code. Though it is possible to purchase professional-grade lock picking sets, it’s also possible to make your own from everyday household items. There are two main types of locks found on residential doors – pin-tumbler locks and wafer tumbler locks – both of which can be opened with a few tools that you have around your house.

For a pin-tumbler lock, you will need a tension wrench and at least one pick. The tension wrench allows you to apply force while manipulating the pins in order to open the door. Picking tools, such as paper clips or other metal objects (including traditional lock picks made from metal) are used to lift and separate pins within the cylinder. The process takes time, patience and practice, but it will ultimately gain entry when no other means are available.

When dealing with wafer tumbler locks, a more specialised toolkit is required as pins are located on both sides of each wafer instead of within a single cylinder like in pin-tumbler locks. You’ll need two separate picks – one for each side – along with a tension wrench and possibly tweezers for retrieving pieces once they slip free from the chambers. Properly crafted picks can greatly increase success chances so if you’re unfamiliar be sure to invest in quality equipment before attempting any do-it-yourself projects!

Steps for Unlocking the Jam Door Lock

A Jam door lock is a very secure lock which is usually installed in commercial or residential buildings. It is usually difficult to open without a key, but there are certain techniques that can be used to help you get into the lock without a key. This article will outline some simple steps to help you open a Jam door lock without a key.

Step 1: Remove the Screws

If your Jam Door lock has externally visible screws, you’ll want to begin by removing them. First, locate any small screws located near the angle of the keyhole in the door. These screws are typically used to hold the locking mechanism in place and may require a Phillips head screwdriver for removal. Once these screws are removed, you should be able to easily remove the deadbolt from the door.

Next, locate any larger Phillips head screws located on either side of the lock cylinder. If there is an escutcheon plate covering these screws, use a utility knife or flat-edged screwdriver to pry off the plate and reveal the larger screws. Carefully unscrew and lift off each cylinder using a flat-edged screwdriver. These longcylinders are usually brightly colored metal that locks into place by pressure fit inside corresponding holes in the frame of the door.

Finally, lightly slide out any visible pins that are used to keep residual pieces connected to each other firmly in place and safely discard them away from children or pets who can ingest them. Remember that most Jam Door locks do not require special steps beyond removing visible external parts to access its inner components – keep your eye out for additional locks that may be hidden away under additional layers!

Step 2: Insert the Paperclip

The next step in opening a Jam Door lock without a key is to insert a paperclip into the keyhole. Begin by straightening out the paperclip, making sure it has some flexibility and bend at one end. With the straighter side of the paperclip facing down, carefully insert it into the keyhole. Move the paperclip around until you feel a groove and move it downwards, being careful not to damage any of the internal components of the lock. If you are unable to locate any grooves, move onto step three and begin using a small screwdriver or knife instead, or alternatively use a lock bumping technique.

Step 3: Use the Tweezers

Using the tweezers, carefully insert them into the lockset. Be sure to handle the tweezers gently, as to not damage the locking mechanism further or cause discomfort when inserting the tweezers.

Gently twist and turn the tweezers until you have reached a point of resistance. This is a good indication that you have reached the inner components of the lock, which will assist with unlocking it.

Try pushing or pulling on the inner components to unlock or move out from their position within the lockset. You may need to angle your tweezers in order to reach these components more easily before performing your actions.

If you notice some resistance while performing this step, do not force any levers with too much pressure as you may cause more difficulties with unlocking your jam door lock without a key. If necessary, lighten up on pressure applied and keep trying until you can unlock it successfully.

Step 4: Use the Pliers

At this point, you should have prepared the tools you need to open the door lock. If a key is not available, use pliers to slowly and carefully turn the cylinder until it pops open. This method requires patience in order to ensure that the pliers do not slip and potentially damage one of the pins in the cylinder. To do this correctly, insert one of the pair of pliers into the keyhole opening and grip it snugly against one of cylinders internal components – either to its right or left side – depending which way you want to turn it. Gently twist the pliers around until each pin slides out slightly on its own. Once all pins are released, the door lock will unlock! Be sure not to force any pins or cause damage as this could prevent from being able successfully unlock your door in future attempts!

Step 5: Use the Hammer

If you are unable to pick the lock, your best bet is to use a hammer. Place the claw tip of the hammer onto the top of the lock and then give it a sharp tap to break through. Doing this will cause the locking mechanism to pop open, allowing you to turn it by hand. Be careful not to hit it too hard or you may damage the lock or hurt yourself. Once you have opened the lock, make sure it is unplugged if necessary and remove any screws that are holding it in place before removing it from the door. Now you can replace your old jammed lock with a new one.

Step 6: Use the Lock Pick

Once you have the necessary tools, use a tension wrench to insert into the keyhole and apply light pressure. With your other hand, insert your lock pick into the keyhole and work it around gently until it catches onto something. Apply light pressure on the pick while you turn the wrench slightly. If you do not feel any resistance, adjust the tool and apply light pressure in different directions until you feel something move. Once it feels like something is moving, continue turning until you hear a “pop” as the lock opens.

Be sure to practice caution while picking doors so that you do not damage or break any of the components of your lock!
