How To Unlock A Deadbolt From The Inside

Deadbolts are a fundamental component of home security, offering a reliable barrier against unwanted intrusions. However, there may come a time when you find yourself locked inside and need to unlock the deadbolt without a key. Whether you’ve misplaced your keys or encountered a malfunction, knowing how to unlock a deadbolt from the inside is a valuable skill. In this article, we’ll explore the steps to unlock a deadbolt from the inside safely and efficiently.

Step 1: Identify the Type of Deadbolt

Before attempting to unlock the deadbolt, it’s essential to identify its type. Deadbolts typically fall into two categories: single-cylinder and double-cylinder deadbolts.

  • Single-Cylinder Deadbolt:
  • This type features a keyhole on one side and a turn knob or lever on the other. You can unlock it by turning the knob or lever from the inside without a key.
  • Double-Cylinder Deadbolt:
  • These deadbolts have keyholes on both sides, requiring a key to unlock from both the inside and outside. If you’re locked inside with a double-cylinder deadbolt and don’t have the key, unlocking it can be more challenging.

Step 2: Locate the Turn Knob or Lever

If you have a single-cylinder deadbolt, locating the turn knob or lever is the next step. This knob or lever is typically found on the inside of the door, often near the center or slightly below the center.

Step 3: Rotate the Turn Knob or Lever

Once you’ve located the turn knob or lever, rotate it in the counterclockwise direction. This action retracts the deadbolt latch from the strike plate in the door frame, unlocking the door. If the knob or lever doesn’t turn easily, applying gentle pressure while turning can help.

Step 4: Test the Door

After rotating the turn knob or lever, attempt to open the door by pushing or pulling it. If the deadbolt has been successfully unlocked, the door should open without resistance. If the door remains locked, double-check that you’ve rotated the turn knob or lever fully.

Additional Tips:

  • Lubricate the Deadbolt: Periodically lubricating the deadbolt mechanism with graphite or silicone spray can prevent it from sticking or jamming, making it easier to unlock.
  • Keep Spare Keys: To avoid getting locked inside due to misplaced keys, consider keeping spare keys in accessible yet secure locations, such as a key holder inside your home.
  • Install an Emergency Release Mechanism: For added safety, consider installing an emergency release mechanism on your deadbolt. These devices allow you to unlock the door quickly from the inside in case of an emergency, such as a fire.

How To Open A Locked Door From The Outside

Finding yourself locked out of your home or a room can be a frustrating experience. Whether it’s due to a misplaced key or a malfunctioning lock, knowing how to open a locked door from the outside can save you time, money, and stress. In this article, we’ll explore several methods and techniques to unlock a door when you find yourself on the wrong side of it.

Method 1: Use a Spare Key

The most straightforward solution to unlocking a door from the outside is by using a spare key. If you have a spare key hidden nearby, retrieve it and use it to unlock the door. Common hiding spots for spare keys include under doormats, inside fake rocks, or in discreet key holders mounted near the door.

Method 2: Try Different Keys

If you don’t have a spare key but have access to other keys, such as those belonging to family members or roommates, try them in the lock. Sometimes, especially in households with multiple locks, keys can be mistakenly switched or misplaced. Testing different keys might reveal one that fits the lock and allows you to unlock the door.

Method 3: Use a Credit Card or Plastic Card

The credit card method is a classic trick for unlocking doors with spring bolt locks.

Here’s how to do it:

  1. Insert the edge of the card between the door and the doorframe, just above the latch.
  2. Wiggle and slide the card downward while simultaneously pushing the door away from the frame.
  3. Apply slight pressure to the card as you wiggle it, attempting to push the latch back into the door.
  4. Once the latch is pushed in, the door should open.

Method 4: Use a Lock-Picking Set

Lock picking is a skill that requires practice and patience, but it can be an effective way to open a locked door without a key. If you have a lock-picking set and some experience with lock picking, you can attempt to manipulate the pins inside the lock to unlock it. However, it’s essential to emphasize that lock picking should only be done on locks that you own or have explicit permission to pick.

Method 5: Call a Professional Locksmith

If all else fails or if you’re uncomfortable attempting any of the methods mentioned above, it’s best to call a professional locksmith. Locksmiths are trained and equipped to handle various types of locks and can quickly and safely unlock your door without causing damage.


Can a deadbolt be opened?

A deadbolt can be opened. Deadbolts are designed to provide security by locking a door in place, but they can be unlocked using various methods. Depending on the type of deadbolt, you can unlock it from the inside with a key, turn knob, or lever. Additionally, there are techniques like lock picking or using a spare key from the outside that can also unlock a deadbolt.

Can a burglar open a deadbolt lock?

While deadbolts are generally more secure than standard latch locks, determined burglars with the right tools and skills may still be able to bypass them. However, using a deadbolt significantly increases the time and effort required for a burglar to break into a property, often serving as an effective deterrent. To enhance security, consider installing high-quality deadbolts, reinforcing door frames, and implementing additional security measures such as alarms or security cameras.

How do you unlock a deadbolt with a card?

Unlocking a deadbolt with a card is a technique commonly used for spring bolt locks.
To unlock a deadbolt with a card, follow these steps:

1. Insert the edge of the card between the door and the doorframe, just above the latch.
Wiggle and slide the card downward while simultaneously pushing the door away from the frame.
2. Apply slight pressure to the card as you wiggle it, attempting to push the latch back into the door.
3. Once the latch is pushed in, the door should open. This method works best with older spring bolt locks and may not be effective with newer or more secure locks.

Conclusion: Getting locked out of your home or a room can be a frustrating and stressful experience, but it’s not an insurmountable problem. By employing the methods outlined in this article or seeking the assistance of a professional locksmith, you can regain access to your space and alleviate the inconvenience of being locked out.
