Open the Lock

Opening a three lever door lock without a key is not an easy task, but it is possible. You will need to have the right tools and knowledge in order to do this correctly. In this article, we will look at different ways to open a three lever door lock without a key. We will discuss various methods, such as picking the lock and using a bump key. We will also talk about safety measures that you should take when attempting to open a three lever door lock without a key.

Insert a tension wrench into the bottom of the keyhole

Inserting a tension wrench into the bottom of the keyhole and gently exerting slight pressure is the first step to unlocking a 3 lever door lock without a key. A tension wrench is a small L-shaped tool used for lock-picking designed to fit and turn within the bow of a lock. It’s important to not apply too much pressure when inserting the tension wrench as this can distort or damage the internal pins within the lock. After inserting it, apply light pressure against it in either clockwise or counter-clockwise direction as appropriate for your type of lock. Before continuing further, you will likely need to determine which direction applies to your particular 3 lever door lock.

Apply pressure to the tension wrench

Using pressure on the tension wrench (or tension bar) is a common method used to open 3 lever door locks without a key. A tension wrench is usually made of metal and inserted into the small hole in the handle of the lock. This tool is then used to gently apply pressure while turning in the same direction as you would if you had a key. If using this method, it’s recommended that you wear protective eye and ear protection as you may have to apply significant force when opening the lock.

It can take several tries before you find success with this method, so be patient as different door locks have different levels of sensitivity to applying torque and/or tension. Once applied correctly, you should see and or hear an audible sign (like a click sound) indicating that your door lock has been opened properly.

Insert a pick into the top of the keyhole

The easiest and fastest way to open a 3 lever door lock without a key is using a slim-jim pick. This method involves inserting the narrow end of the pick into the top of the keyhole and applying steady, even pressure across the top surface in order to depress all three levers inside. You will likely feel some resistance and then each lever should release sequentially. Continue to insert the pick until you hear each lever click. Once all three have been depressed, you may have to jiggle or rock the pick slightly in order to turn it, which should open your lock.

Manipulate the pins in the lock until it opens

Opening a 3 lever door lock without a key can be achieved using basic lock-picking tools, such as a set of tension wrenches and picks. The first step is to insert the tension wrench into the bottom of the keyhole and apply slight upward pressure. This will simultaneously engage multiple pins inside the cylinder of the lock. Next, insert a pick into the keyhole and manipulate each pin, one at a time, until they click into place and allow you to turn the tension wrench until it is parallel with the edge of the door. By applying pressure with your fingertip onto each pin in turn while turning the wrench you will eventually be able to unlock your door. It may take longer than expected so remain patient throughout this process. Once unlocked you should leave your toolkit in a secure location or keep it with you when travelling away from home in case another similar situation presents itself during your travels


Opening a 3 lever door lock without a key may seem like a difficult task. Luckily, there are a few methods you can use to get the door open without causing any damage to the lock or the door. This section will provide you with some troubleshooting tips for opening your 3 lever door lock without a key.

Make sure the tension wrench is in the correct position

Before you attempt to pick the lock, ensure that you are using the correct type of tension wrench. A tension wrench is a small, L-shaped tool typically used for manipulating locks. It is inserted into the keyway and rotated in the lock to apply torque to the plug, which is then used to manipulate the pins of the lock. The exact size and shape of a tension wrench may vary depending on what kind of lock you are trying to pick; however, they all share certain features in common.

Once you have identified which type of tension wrench you need for your specific lock, take note that it should be placed in either a vertical or horizontal orientation depending on the design of your particular 3 lever door lock. The orientation can be identified by trial-and-error rotation inside the keyway until there is resistance. Once this position has been determined, grip it tightly with your non dominant hand – usually with pliers – as this will allow for better control when manipulating pins inside your lock’s mechanism.

Make sure the pick is inserted at the correct angle

Before attempting to open a 3 lever door lock with any kind of pick, it is important to make sure that the pick is inserted at the correct angle. You should insert the pick into the hole in the lock face where a key would normally go and angle it so that it curves slightly towards you. It is important that you hold it at this angle in order to ensure that it makes contact with all 3 levers within the lock, allowing you to manipulate them accordingly. Additionally, ensure that your pick has been properly lubricated before attempting to open any locks as this will reduce friction and make it easier for you to slide your picks in between the lever pins.

Make sure the pins are being manipulated correctly

Before attempting to pick the lock, you should make sure the lock pins are being manipulated correctly. When the cylinder is pinned in the locked state, there should be several springs or plungers holding each pin in place at different depths. Whenever a lever is lifted, a corresponding plunger should be activated that allows all pins in that lever to drop down when pressure is increased on each pin. If a plunger is not pushing on its pin and just sliding back and forth without it dropping in depth when pressure is applied, that could suggest an issue with the mechanism that needs to be addressed before trying to open the lock without a key.


After exploring the various options for opening a 3 lever door lock without a key, it is clear that locksmiths and lock picking tools offer the most reliable solutions. Lock picking tools offer the simplest and fastest solution, while a locksmith can open the lock without causing any damage. They can also provide key replacement if necessary.
