Drilling a hole in a cylinder lock is a method typically used to bypass the lock mechanism when traditional methods like picking or using a key are not possible. This process aims to destroy the internal components, specifically the pins, to allow the lock to turn and open.
Drilling a Cylinder Lock: A Step-by-Step Guide
When faced with a locked door and no other entry options, drilling the lock cylinder is a destructive technique that can provide access. This method focuses on targeting the pin mechanism within the cylinder.
Here are the fundamental steps involved, based on standard practices:
Preparation
Before you begin, ensure you have the necessary tools, which typically include:
- A drill
- Appropriate drill bits (a 3mm drill bit is a common starting size)
- A center punch
- A hammer
- Safety glasses (highly recommended)
The Drilling Process
The process involves creating a starting point and then drilling into the lock cylinder at a specific location to disrupt the pins. Follow these steps:
- Make an indentation on the lock by striking the punch with a hammer two or three times to make a guide point. This indentation prevents the drill bit from slipping when you start drilling. Choose a spot on the face of the cylinder, usually just below the keyway, targeting where the pins are located.
- Begin drilling using the 3mm drill bit. Start slowly to ensure the bit catches the guide point.
- Drill a hole through the lock cylinder on the guidance point. Maintain steady pressure as you drill deeper into the cylinder.
Your objective is to destroy the pins inside the lock to open the lock. As you drill through the cylinder, the drill bit will sever the small metal pins that prevent the cylinder from turning. Once the pins are sufficiently destroyed, the cylinder should be free to rotate, allowing the lock mechanism to disengage.
Important Considerations
- Last Resort: Drilling is a destructive method. The lock cylinder will be permanently damaged and will need to be replaced afterward.
- Accuracy: Hitting the pins is crucial. Incorrect placement of the drill hole may not disable the lock.
- Safety: Always wear safety glasses to protect your eyes from metal shavings.
This process is a direct way to bypass a locked cylinder when necessary by targeting the pin tumblers that secure it.
