how to pick a door lock with a credit card 1

Credit cards are familiar tools in our daily lives. Whether it’s shopping, traveling, or enjoying discounts, credit cards play a role in various scenarios. Just as a toolbox contains various tools, different type of card is needed for different occasions. As a result, many people possess multiple credit cards to meet different needs.

Before picking a door lock, the first step is to check if you have a suitable card in your wallet. This tool needs to have a certain level of flexibility and appropriate thickness so that it can be bent and inserted into the door smoothly.

Unfortunately, you haven’t found the right tool. But don’t worry, plastic cards such as bus cards, gift cards, or hotel cards can also be used, as long as their size and shape are suitable. (However, make sure that the selected card doesn’t have an important use, as this process could potentially damage or deactivate the card.)

If you can’t find a suitable card, you can also create a plastic card temporarily. Material required – a hard plastic such as a plastic bottle or a rigid plastic container. This way, you can proceed with the next steps.

Can You Actually Use a Credit Card to Pick a Lock?

Yes, but not always. Picking locks with a credit card typically works on older locks and simple door locks with a spring latch mechanism. It also works on improperly installed door locks. Here are some types of locks vulnerable to this technique:

Basic Spring Latch Locks

Basic spring latch locks are traditional door locks, such as bolt locks and cylindrical locks. They use a spring-loaded latch mechanism to lock. Upon closing, the latch expands into the frame of the door to lock it.

By inserting a credit card or a thin piece between the door frame and the door, the latch can be pushed back into the door, thus unlocking it. These locks lack higher-level complexity and security features.

Older Padlocks

Certain older padlock models, especially those with basic spring latch mechanisms, may be susceptible to lock picking using a credit card. These padlocks are often used for lower-security applications and may not have the same protection as modern padlocks.

Low-Quality or Cheap Locks

Inexpensive locks with poor construction or lacking advanced security features may be more susceptible to manipulation using a credit card. These locks may not effectively resist simple bypass techniques.

Many modern locks, especially those used for high-security applications, are designed to resist credit card lock picking. Therefore, not all kinds of door locks are easily bypassed using a credit card. If you need to unlock a certain area, it’s essential to seek professional locksmith assistance to ensure a legal and secure solution.

How to Pick a Door Lock with a Credit Card? Simple Steps

Step 1: Confirm the Lock Type

Lock picking with a credit card only works on spring latch locks and doesn’t affect deadbolts. Therefore, you need to first examine your door lock to confirm if it has a spring-loaded latch. Understand the type of lock, the door opening direction, and then proceed to the next step. Different installation methods also lead to different unlocking techniques. Let’s explore this together.

Step 2: Prepare the Tools

You’ll need a credit card or a similar plastic card as a tool. Depending on the door opening direction and the lock position, you may need to make slight adjustments to the card. Here are two typical examples for your reference:

Cutting the Card:

If the door opens outward, meaning the hinges are on the outside, you need to cut a small notch in the card so that it can smoothly fit into the gap and contact the latch.

Bending the Card:

If the door opens inward, you can directly insert the card into the gap. However, if the card feels difficult to insert, you can gently bend it to better match the position of the latch.

Step 3: Insert the Card

This is a crucial step in the entire process. After correctly locating the position of the latch, insert the card above where the latch is located.

Step 4: Wiggle and Apply Pressure

Gently push the card into one side of the door and simultaneously apply slight downward pressure. Then, try to wiggle and bend the card downward to help the latch return inside the door. Repeat this back-and-forth motion while turning the handle, this should eventually open it.


Finding Alternative Solutions

Pick a lock with credit card is not the only method; here, we will also suggest some other alternative solutions for unlocking doors.

Utilize Emergency Key

For emergency access, door locks are typically equipped with emergency keys. To prevent being locked out, emergency keys are generally not kept inside the house. Most people choose to keep them in their cars, with trusted family or friends, at the office, and so on. If you remember where your emergency key is, you can use it to unlock the door.

Can credit card access for door unlocking be prevented?

Certainly. Implementing credit card unlocking is a traditional and ancient lock-picking technique. With the advancement of technology, people have gradually developed various security measures to counter this method. The following are some common methods to resist credit card lock-picking:

Upgrade to Modern Locks

how to pick a door lock with a credit card 8

In advanced locks, security technologies are integrated with locking mechanisms, providing greater intelligence, more convenience, and higher security. To address various common lock-picking techniques, modern electronic door locks incorporate multiple security technologies, effectively preventing lock-picking incidents.

As one of China’s leading smart lock suppliers, YGS Smart Lock fully utilizes various advanced security technologies to ensure the security of your residence. These include but are not limited to the following:

(1) Multiple Alarm Designs

how to pick a door lock with a credit card 9

Typical alarm system designs include illegal intrusion alarms, low battery alarms, false lock alarms, etc. These alarm designs help homeowners detect abnormal information from the door lock and respond promptly. In cases like credit card unlocking, the door lock will automatically recognize and sound an alarm. Not only does this attract the attention of occupants and neighbors, but it also scares intruders.

(2) Remote Control Design

Upgrading to an online system lock also supports users to remote control and manage their lock. Real-time unlocking records uploading, smart door locks remote controlling, temporary authorization code allowing, front door camera monitoring, etc. 

Real-time unlocking records are uploaded, enabling remote control of the door lock, temporary authorization for unlocking, front door camera monitoring, etc. Even when away from home, users can stay informed about the door lock’s status and have peace of mind.

(3) Hidden Mechanical Keyhole Design

how to pick a door lock with a credit card 10

A hidden mechanical keyhole is not easily discovered, enhancing the security of the door lock. This prevents curious children or unauthorized lock-picking attempts from damaging the mechanical keyhole and increases the difficulty of technical lock-picking.

(4) Free Handle Design

how to pick a door lock with a credit card 11

The free-handle design effectively prevents techniques like peephole manipulation, square bar manipulation, plastic card methods, and other unauthorized opening methods. Users need to press the anti-tampering button and press the handle at the same time to unlock.

(5) Five-Lock Tongue Triple-Linkage Design

The reinforced five-tongue linkage structure lock body is simple, reliable, and performance-stable. Credit card unlocking is completely ineffective.

(6) Dual Locking Design

Supports indoor deadlocking, essentially adding an extra lock to your door. When the door is deadlocked, opening the door with external physical means becomes nearly impossible, enhancing security.

Strengthen Doors and Door Frames

Reinforcing doors and door frames can enhance protection and prevent unauthorized entry. Specific measures include: installing doors made of thicker steel or other robust materials; using thicker metal or increasing the structural strength of door frames; reinforcing with longer screws, and more.

Use Secure Portable Locks

Using portable high-security locks adds an additional layer of protection, working in conjunction with existing door locks to increase the difficulty of entry. Usually installed indoors, they create additional resistance, making entry even more challenging even if the main lock is compromised. See more about portable high-security locks in the below article.

Installing security cameras at the entrance not only monitors the front door area but also acts as a deterrent, preventing illegal entry. Normally, criminals would not dare commit crimes within camera range.


Finally, we must admit that while credit card unlocking remains an intriguing concept, it is not the only way to bypass door locks.

In this era of smart technology, the pursuit of high security continues to expand.
