Unlocking Doors: Plastic Cards To The Rescue

how to unlock door with plastic card

Locking yourself out is frustrating, but there are a few DIY methods to try before calling a locksmith. One common method is to use a plastic card to open a locked door. This technique only works on simple knob locks with a spring-loaded latch or slanted-latch. First, examine the lock to confirm it has a spring-loaded latch. Next, insert the card into the gap between the door and the frame, sliding it down next to the doorknob. Push the card in as far as it will go at a 90-degree angle to the door. Then, tilt the card towards the doorknob until it almost touches. This method may take patience and practice, but it can be an effective way to unlock a door in a pinch.

Confirm the type of lock and door opening direction

Confirming the type of lock and door-opening direction is a crucial step in unlocking a door with a plastic card. Here are some detailed instructions to help you with this process:

First, identify the type of lock you are dealing with. The two most popular types of locks are Kwikset and Schlage. Look for any markings or stamps on the lock, such as “SC1” for Schlage or “KW1” for Kwikset. If there are no visible markings, examine the shape of the lock's head, as this can also help identify the type. Deadbolts, for example, may have the name stamped on the face of the lock. Additionally, consider the locking mechanism. The most widely used locking mechanism today is the pin cylinder, often referred to as a “Yale” lock. Other mechanisms include wafer locks, which use flat single pieces of metal, and lever locks, which are popular among lock pickers.

Next, determine the direction in which the door opens. Typically, interior doors swing into the room and open towards the nearest perpendicular wall. This design maximizes the open space within the room when the door is open.

By understanding the type of lock and the door-opening direction, you can better assess if unlocking the door with a plastic card is feasible and adjust your technique accordingly. Remember that this method generally works on doors with simple knob locks, spring-latch locks, or slanted-latch locks, which are commonly found on interior doors.

Cut a small notch in the card if the door opens outward

If the door opens outward, meaning the hinges are on the outside, you will need to cut a small notch in the card. This will allow the card to smoothly fit into the gap and make contact with the latch. The notch will enable the card to reach the latch and open the door.

To begin, locate the position of the latch by gently pushing the card into the gap between the door and the door frame. Once you have found the latch, you can start to cut the notch. The notch should be small and placed on the side of the card that will face the latch.

When cutting the notch, ensure that you do not cut too deeply into the card. You only need to create a small indentation for the latch to catch onto. A gentle, smooth motion will help guide the latch back into the door.

After cutting the notch, insert the card into the gap, above the latch. Gently push the card into the gap and apply slight downward pressure. Wiggle and bend the card downward to guide the latch back into the door. Repeat this motion while turning the handle, and the door should eventually open.

Remember, this method may not work on all doors. It is typically effective on doors with simple knob locks, spring-latch locks, or slanted-latch locks, often found on interior doors.

Insert the card into the gap between the door and frame

To unlock a door with a plastic card, you must first identify the type of lock and door opening direction. This is important because the way you insert the card into the gap between the door and the frame will depend on these factors.

If the door opens outward, meaning the hinges are on the outside, you will need to cut a small notch in the card. This will ensure that the card can smoothly fit into the gap and make contact with the latch. Once the notch is cut, wiggle the card into the gap between the door and the frame, at the same height as the handle.

If the door opens inward, you can directly insert the card into the gap between the door and the frame. Slide the card into the vertical crack between the door and the frame, pushing it in as far as it will go at a ninety-degree angle to the door.

It is important to note that this method of unlocking a door with a plastic card will only work on doors with a simple knob lock and a spring-loaded latch or slanted-latch. It will not work on deadbolts or high-security locks. Additionally, make sure that you have the right to open the door to avoid any legal issues.

Push the card in at a 90-degree angle to the door

To unlock a door with a plastic card, you will need to push the card in at a 90-degree angle to the door. This method will only work on doors with a simple knob lock, a spring-loaded latch, or a slanted-latch. It will not work on deadbolts or high-security locks.

First, examine the door lock to confirm if it has a spring-loaded latch. Understand the type of lock and the door-opening direction, and then proceed. If the door opens outward, meaning the hinges are on the outside, you will need to cut a small notch in the card so that it can smoothly fit into the gap and contact the latch. If the door opens inward, you can directly insert the card into the gap.

To unlock the door, wiggle the card into the gap between the door and the door frame. Slide the card into the vertical crack between the door and frame. Insert the card into the gap between the doorknob and door frame, then slide it down next to the doorknob. Push the card in at a 90-degree angle to the door as far as it will go. To see the location of the door frame more easily, push the door back as far as it can go with your other hand.

The plastic is sturdy but more flexible, which makes the process easier and less risky. You can also use a piece of plastic cut from a soda bottle, which is more flexible than a card and may be easier to manipulate.

Call a locksmith if all else fails

If you've tried all the DIY methods and are still locked out, it's time to call a locksmith. While this may be a pricey option, it is a safe and reliable one. Locksmiths have the tools and expertise to unlock doors quickly and without damage. This option is especially useful if you are dealing with a high-security lock, as DIY methods are unlikely to work on these.

Calling a professional locksmith is also a good idea if you don't feel confident in your ability to use a credit card or other tools to open the door without causing damage. Attempting to unlock the door without the proper experience can sometimes make matters worse.

It's important to remember that unlocking a door without permission can be considered illegal and result in severe consequences. So, before attempting any method, make sure you can prove that you have the right to open the door.
