What Is a Cylindrical Lock?

Before exploring how to open a cylindrical lock, it is necessary to know what exactly it is.

A cylindrical lock is a locking mechanism on residential and commercial doors. It’s called "cylindrical" because of its round cylindrical shape where the key is inserted. These locks are valued for their strong and relatively simple design.

Cylindrical locks are composed of a lock chassis, a separate latch bolt, and operable trim, which is either levers or knobs and roses behind the trim.

In keyed functions, the cylinder is located inside the lever or knob. In conventional cylinders, the cylinder must be completely removed from the lock to obtain it for lock rekeying.

How to Open a Cylindrical Lock Without a Key?

Here are a few ways you can unlock a cylindrical lock:

1. Lock-Picking with Professional Tools

Here are the steps to open the cylindrical lock using professional tools:

Step 1: Insert the Tension Wrench

• At the bottom of the keyway, place the tension wrench carefully.
  
  
• Gently apply enough pressure to the direction to turn the key.

Step 2: Use the Pick

• Now, you can insert the pick in the keyway and look for the pins.
  
  
• Lift each pin until you hear or feel a slight click.
  
  
• Repeat for all pins while maintaining tension with the wrench.

Step 3: Turn the Lock

Once all pins are set, turn the tension wrench to open the lock.

2. Using a Paperclip or Bobby Pin

A paperclip or bobby pin can be improvised if professional tools are unavailable. Here is how:

Step 1: Straighten one tool to act as a pick, leaving a slight bend at the end.

Step 2: Use another tool as a tension wrench.

Step 3: Follow the same steps as professional lock-picking.

This method may require patience and practice.

3. Bypassing the Lock Mechanism

Some cylindrical locks can be bypassed without picking:

• Locate the Latch: Use a credit card or thin tool to push the latch inward.
  
  
• Turn the Knob: Simultaneously turn the door handle while pressing the latch.

This technique works best on older or poorly installed locks.

When to Use Drilling as a Last Resort?

Drilling a lock should only be done if all other methods fail, as it destroys the lock. Here are some of the major steps below:

Step 1: Use a drill with a high-speed metal bit.

Step 2: Drill through the cylinder to break the pins.

Step 3: Now, use a flathead screwdriver to turn the lock.

Always wear safety goggles and proceed cautiously to avoid damaging the door. However, if these locks are too difficult to install, consider upgrading to a fingerprint door lock for advanced security solutions.

Preventive Measures for Cylindrical Locks
