Want to know how to open a deadbolt door without a key? The power drill’s tip should have a drill bit in it. Apply lubricant there and on the deadbolt, paying close attention to the keyhole. Insert the drill bit firmly until the tumbler pins come off. Unlock the deadbolt by inserting a screwdriver.

In this article, we’ll examine how to quickly unlock a deadbolt without a key. Please keep reading.

Why Deadbolts Are A Little Difficult To Get Around?

Most exterior doors use two different types of locks: a deadbolt and a doorknob (also referred to as a “deadlatch”).

When the door is closed, a latch in a doorknob lock is automatically pushed into the doorframe and held in place by a spring.

A spring holds the latch in place, making it susceptible to any attack that can make the spring retract. A thin piece of material, like a credit card, is slid between the door’s cracks during a common attack known as loiding, which compresses the spring latch.

In contrast, deadbolts don’t employ a spring. Instead, a key or thumb turn must be used to mechanically retract them. Because of this, they cannot be loaded, and it is much more difficult to directly control the bolt.

How To Use Bobby Pins To Open A Deadbolt Lock?

If you find yourself trapped inside the room, this is the fastest and safest way to open a bolt lock. We will provide you with a brief summary of the solutions, though. Simply carry out the steps listed below in order.

  • Bring two bobby pins that are each 2 cm long. The pin is now simpler to place in the keyhole.
  • Remove the rubber ball (if any) from the end of the pins to make them clean.
  • Now create an “L” shape by bending one bobby stick or pin.
  • Continue to unfold the other stick. It makes sure that the pin will droop and drag the lock’s clip through the deadbolt hole.
  • Take the “L” shaped stick and insert it towards the lock hole (bottom part).
  • At the same time, put your unfolded pin into the upper part of the hole.
  • Next, apply side pressure with a pin that has been folded.
  • In the same way, apply the same pressure to the other pin and move it accordingly.
  • In order for the inside clip to move slightly, repeat the process a specific number of times (six).
  • If you are able to move, take the unfolded pin out of the keyhole.
  • Now, try rotating the keyhole repeatedly until it unlocks (use an L-shaped key).
  • Take out the bent pin as you unlock the deadlock clip.

Even though this process occasionally seems irksome, patience is required. This procedure makes sure the lock can be used again. In addition, it is a simple technique that anyone can use if they misplace the key. This process can also be used to unlock a deadbolt using a paperclip.

How To Use A Screwdriver To Open A Deadbolt Lock?

From within your room, locked? A screwdriver is the most practical tool to use to unlock a deadlock, so bring one. The internal lock clip can be easily rotated using this tool’s strength. However, users should follow certain procedures when using this tool to break a deadlock.

Bring An Appropriate Screwdriver

Not all shaped screws fit into the deadbolt keyhole. So bear a few things in mind before beginning the procedure.

  • A screwdriver that can reach the deadbolt clip should be used.
  • Thicker tools fit through the keyhole with ease.
  • Bring a screw that is easy to hold and makes your job easier.
  • Rotating the deadlock clip requires a screwdriver that is undamaged, substantial, and powerful.
  • The driver’s tip ought to be level.

Put The Driver Into The Keyhole.

  • Enter the tool side by side towards the deadlock
  • Ensure that the flat-edge touch the locking clip
  • Put a little upward pressure now to make the tumblers rise.

Rotate The Screwdriver Clockwise

Apply a little pressure to rotate the deadlock while everything is inserted into the lock hole. Retry if your initial effort was unsuccessful. So that the locking clip can turn, keep the tumbler up. Try the process at specific times, and exercise patience. To restart the method, take out or drag the driver.

How To Use A Credit Card To Open A Deadbolt Lock?

To unlock the deadbolt if you can’t find any bobby pins or screwdrivers, apply for a credit card. Additionally, you could use a sturdy plastic card that is similar.

Now, before beginning, bear a few things in mind. Only springing deadbolt locks can be opened using credit cards. It’s challenging to open deadbolts with a credit card, though. You must exercise patience and maintain hand steadiness. Anyone finds it challenging to open the door on their first try. The detailed instructions are therefore below.

  • Bring a credit card or some inexpensive plastic swipe cards, like membership cards.
  • If the card is laminated, it will be more useful. Yes, these swipe boards frequently have a solid construction and sufficient flexibility.
  • Verify the length of the plastic card so that it touches the deadbolt’s latch.
  • Insert the cards now parallel to the gap in the door. Your deadbolt latch, which locks the door, is located in this section.
  • As you attach the card tip with the latch, shake it and push it into the keyhole.
  • To open the latch, bend the credit card away from the deadbolt.

Just keep in mind that this method only works with deadbolt locks that have conventional door knobs. This is another way to use a knife to open a deadbolt lock. However, be certain that there is space between the doors. If not, you are unable to turn the deadbolt latch using any tool.

How To Bump A Deadbolt Lock To Open It?

Lock bumping is another highly efficient method for disabling deadbolts without the original key. Lock bumping is a technique that uses a grinded-down key called a “bump key” that has been cut to its maximum depths. For your specific deadbolt, you can either make your own bump keys or purchase pre-made ones online.

To create your own, you will need a tool to grind down a key that fits into your deadbolt’s keyway and another key that you don’t mind breaking. Almost every neighborhood hardware store carries both of these items.

It’s time to get to work once you have your bump key! Completely insert it into the key, then slowly pull it out until the last pin in the lock drops. Then turn the key with light pressure.

Strike the back of the key with a rubber mallet or your hand, quickly forcing it into the lock. The pins will be sent up by being struck by the key’s teeth. The pins will fully disengage from the lock’s plug with just the right amount of force and some luck, allowing the lock to open.

Even though the majority of pin-tumbler deadbolts can be defeated using this technique, it might not always be successful. Anti-bump features on higher-quality deadbolts may be used to stop lock bumping attempts.

How To Use A Drill To Open A Deadbolt Lock?

Consider drilling the lock if you don’t mind completely destroying your deadbolt.

Drilling a lock successfully can be accomplished in a number of ways, and there are numerous potential drilling targets. The shear line, the top stack of pins (driver pins), the bottom stack of pins (key pins), the springs, and even the screws holding the deadbolt to the door can all be drilled.

Understanding a lock’s mechanism and the typical anti-drill countermeasures is the best way to know which technique to use in which circumstance. Harder steel or ceramic parts that protect weak areas are typically used as anti-drill components.

For instance, your deadbolt probably uses hardened anti-drill pins that are more challenging to drill if you look into the keyway and see a steel front pin rather than a brass one.

However, low-cost deadbolts frequently don’t have anti-drill defenses, so you can probably just drill directly above the keyway to target the shear line.

To drill a lock follow these steps:

  1. Decide where you want to drill, then use a small drill bit to create a short starting hole that will serve as a guide for a larger bit.
  2. Starting with a 1/8th inch drill bit, begin drilling until you feel your bit bore through 5 pins
  3. Upgrade to a 1/4th inch drill bit and repeat
  4. Use a flathead screwdriver to turn the lock by inserting it into the keyhole.

Check the hole to see if the sixth pin is present if it won’t open. If there is a second pin, drill a little further to remove it as well before attempting to open the lock once more. In order to cause a little bit more damage, you might need to upgrade to a slightly larger drill bit if there isn’t another pin and the lock won’t open.

How To Break The Glass To Open A Deadbolt Lock?

You can break the glass on the door you’re trying to open or reach through a window to the deadbolt’s thumb turn if there is one nearby and the door has a glass panel.

I really don’t advise this course of action unless it is an emergency. By trying to reach through a broken window, you might end up in deeper trouble. In addition, replacing a broken window can cost more money than just calling a locksmith.

Call A Locksmith

If all else fails, you might need to hire a locksmith to open the door. The majority of locksmiths have the equipment and expertise required to unlock almost any door without causing any lock damage.

Additionally, the cost of replacing a broken lock, door, or window is typically much less with locksmiths. The average cost of being locked out is about $150, though this will depend on your location and the locksmith. Here, you can find out more about calling a locksmith and their fees.

Calling a locksmith might be your best option if you’re stuck, don’t know what to do, or don’t have the necessary tools.


So, this is a comprehensive guide on how to open a deadbolt without a key. We have listed several safe and urgent lock removal options here.

Keep in mind that there are only three types of deadbolts commonly available on the market: single knob, double knob, and thumb-turn. The most effective tools for releasing the double knob and thumb turn deadlock are bobby pins, paper clips, screwdrivers, and knives.

By keeping a spare key outside, giving it to a friend or neighbor, or switching to a keyless entry system, you can avoid being locked out in the future. Though we sincerely hope you never need it, it’s always a good idea to be ready!
