Introduction

Before we delve into the mechanics of lock picking, it's important to emphasize that attempting to access a lock without authorization is illegal and potentially dangerous. This article aims to provide information for educational purposes only. If you need assistance opening a locked door, it is highly recommended to contact a professional locksmith. They can ensure that your actions are both legal and safe.

Understanding Round Key Locks

Round key locks, often referred to as tubular locks, are commonly found in residential areas, particularly on inner doors such as bathroom doors. These locks often feature a hole in the center of the door knob. This hole is not for security purposes but serves to indicate that the room is being used for privacy and prevent unauthorized entry.

How to Pick a Tubular Lock

There are generally three methods to pick a tubular lock:

Option 1: Using a Tubular Lockpick

This is the most reliable and straightforward method. A tubular lockpick is specifically designed to fit the keyway of a tubular lock. The process involves inserting the pick into the lock, adjusting it, and twisting and wiggling until the lock opens. This action impresses the lock, and the tool can be used to create a key code, which can then be used to cut a new key.

If the lock does not respond to the impressioning technique, the same tool can be used to single-pin pick the lock, which still results in a repeatable key. This method is often more reliable and can be used on most tubular locks, provided the lock's binding pins are compatible with the tool.

Option 2: Impressment with Improvised Tools

This method is less reliable but can be useful in emergencies. You can use various common objects to impress the lock, such as the plastic barrel of a Bic pen or plastic straws. By sliding the tube onto the lock and wiggling and twisting it, the plastic may deform on the binding pins, creating a one-time impression of the lock. While this method might not provide a precise key, it can still allow for entry on one occasion.

Note that the reliability of this method can vary depending on the lock and the tool used. Some locks respond better to certain materials, while others may not be impressed at all. It's recommended to use a professional tool for the best results.

Option 3: Manual Single Pin Picking

Single pin picking is a more tedious and less ideal method. Unlike the other two methods, manual single pin picking typically requires the lock to be picked multiple times to find the correct depth for each pin. This process can involve rotating the core or pin stack several times to open the lock. It is not suitable for inexperienced users and can be quite challenging to execute without the right tools.

For experienced users, single pin picking can be successful, especially if you can carefully pick the lock once and capture the pin depths using an epoxy putty. However, this method requires precise control and stability, and it is more time-consuming than the other methods.

Conclusion

While the methods described above can be effective in certain situations, they are not the most efficient and reliable options for everyone. If you need to frequently open locks, it is highly recommended to purchase the correct key or seek professional assistance. Unauthorized entry can lead to legal consequences and damage to the lock, which may void any warranty or necessitate costly repairs.
