How to Unlock Door with Credit Card

If you forget your key and want to open the door, you can use a credit card to unlock it. Remember, this technique is only effective for doors with a simple handle lock with a spring-then or beveled key. To open the door, insert an ATM card into the gap between the door and the door frame. If you can’t open it, you will use another solution.

Slide an ATM card into the vertical gap between the door and the door frame. Insert the card into the gap between the handle and the door frame, then slide the card down next to the door handle. Push the card into the maximum depth perpendicular to the door. ^{[1] X Research Source}

Tip: To see the position of the door frame more clearly, use your other hand to push the door in as far as possible.

Tilt the card towards the door handle. Push the card toward the doorknob until it almost touches the handle. You can now push the card deeper into the gap between the door and the door frame. ^{[2] X Research Source}

Bend the card in the opposite direction. Bending the card in the opposite direction will cause the card to slide under the inclined part of the bevel key, forcing the key to slide back into the door. Quickly open the door and unlock it on the inside of the door. ^{[3] X Research Sources}

Lean against the door and wiggle the card back and forth to unlock it. If the door cannot open, try leaning against the door while bending the card back and forth a few times. This move puts more pressure on the key and will probably open the lock. ^{[4] X Research Sources}

Check for unlocked windows. Go around the house and check the windows on the ground floor are open. If you detect an unlocked window, you can remove the mesh to open the window. You will then climb into the house through the window. ^{[5] X Research Sources}

Climbing through windows can be dangerous. Only use this method if you are confident in your climbing ability.

Tip: If your home has a back door or a side door, you should also check it. You or a family member may have forgotten to lock these doors.

Call your roommate. If you live with a friend or lover, give them a call to see if they’re nearby. If possible, ask them to stop by your house to open the door for you. Although this method requires you to wait a few minutes on the front porch, it avoids the risk of damage and costly repair fees. ^{[6] X Research Sources}

In addition, you should consider going to a coffee shop near your house to relax if possible.

Call the landlord. This is a very good option if the owner lives there. Call to ask if they’re home and have them open the door for you to come in. Even if they don’t live there, they may work close to your home and be willing to drop by to help. ^{[7] X Research Sources}

Hiring a locksmith is the last resort. If you don’t have a roommate and the landlord can’t help, it may be time to call in a locksmith. Hire them to come to your house to change the locks. It works but costs money, so it’s only a good idea if you have no other choice. ^{[8] X Research Sources}

Note: Remember that your landlord may charge you for a replacement lock and/or damage to the door.

Advice

To avoid being in this situation again, knock on a few more keys and keep one with you and/or hide somewhere near the house.
Some doors are so easy to unlock, you just need to insert the card into the door slot at the height of the handle without tilting or bending the card.

Warning

Have proof that you have the right to open the door, or you could end up in a room where a credit card can’t unlock it!
