How to Open a Chain Lock From the Outside

Tools and Materials You Will  Need to Open a Chain Lock From the Outside

  1. A screwdriver or any flat object with a thin tip
  2. A pair of pliers
  3. A paperclip or bobby pin
  4. WD-40 or any lubricant spray
  5. A hammer (optional)

Step-by-step Guidelines on How to Open a Chain Lock From the Outside

Step 1: Use the Lubricant

The first thing you need to do before attempting to pick a chain lock is to spray some lubricant, such as WD-40, into the keyhole. This will help loosen up any dirt or debris that may be blocking the mechanism. Using a lubricant will also make it easier for you to insert your tools into the lock. This step is crucial because, without it, you may damage your tools or even break the key inside the lock.

Step 2: Bend the Bobby Pin or Paperclip

Take your paperclip or bobby pin and straighten it out, leaving a small hook at one end. This will serve as your makeshift lock pick. You can also use pliers to bend the tip of the paperclip for better grip and control. This technique is especially useful if you have a thick or heavy-duty chain lock. While you may use an actual lock-picking tool, a paperclip or bobby pin is readily available and can do the job just as well.

Step 3: Insert and Wiggle the Tool

Insert your makeshift lock pick into the keyhole and wiggle it around. This step is crucial because you need to find the correct angle and position to push the pins inside the lock. Be patient, as this may take a few tries before you can feel any movement or clicks inside. Inserting the pick too forcefully can also damage your tools or break the key inside the lock.

Step 4: Use a Screwdriver or Hammer (optional)

If you are having difficulty inserting your lock pick, you may use a flat object such as a screwdriver to push and hold down the pins while wiggling your paperclip or bobby pin. You can also use a hammer to tap on the keyhole gently. This will help loosen up any stuck pins inside the lock. Be careful not to hit too hard, as this may damage the lock or your tools.

Step 5: Continue Wiggling and Turning

Once you feel that the pins have been pushed down and are in place, continue wiggling your tool while turning it inside the lock. This motion will simulate a key turning and should eventually unlock the chain lock. Remember to be patient and keep trying until you feel the lock disengage. Make sure to also apply gentle pressure while turning your tool, as too much force can break the lock or your tools.

Following these steps should help you successfully unlock a chain lock from the outside. However, please note that this method may not work for all types of chain locks, especially those with more advanced security features. In such cases, it is best to seek professional help or contact the manufacturer for assistance.

Make Sure to Also Apply Gentle Pressure

We hope that this guide has been helpful and wish you luck in unlocking your chain lock!  Keep in mind to use this knowledge responsibly and only in situations where you have permission to do so. Happy opening!
