Setup

  1. Identify Your Lock Slot: Before attaching the lock, determine the type of security lock slot on your laptop or desktop computer. Common types include T-Lock, Nano (Compact), and Wedge. The Targus 3-in-1 lock comes with interchangeable heads to fit these different slot types. Refer to your device's manual if unsure.
  2. Select the Correct Lock Head: The lock includes three distinct heads. Choose the head that matches your device's lock slot. The heads may be color-coded for easier identification.
  3. Attach the Lock Head: Securely attach the chosen lock head to the cable lock mechanism. Ensure it clicks firmly into place.
  4. Secure the Cable: Loop the galvanized steel cable around a sturdy, immovable object such as a heavy desk leg, bedpost, or other fixed furniture. The loop at the end of the cable allows you to pass the main lock body through it, creating a secure anchor point.

Operating Instructions

Setting the Combination:

The Targus DEFCON 3-in-1 Lock comes with a pre-set 4-wheel combination. To set your personal combination:

  1. Ensure the lock is in the unlocked position (using the current combination, usually 0-0-0-0).
  2. Locate the reset button or mechanism on the lock body. This is typically a small button or a rotating part.
  3. Using a pen or a small pointed object, press and hold the reset button (or rotate the mechanism as per specific model instructions).
  4. While holding the reset button, set your desired 4-digit combination by rotating the number wheels.
  5. Release the reset button. Your new combination is now set. IMPORTANT: Write down your combination and store it in a safe place. Without the correct combination, the lock cannot be opened.

Locking Your Device:

  1. With the cable securely looped around an immovable object, align the selected lock head with your computer's security slot.
  2. Insert the lock head into the slot and push firmly until it clicks into place. The lock's internal jaws and metal cams will secure it to your device.
  3. Scramble the combination wheels to secure the lock.

Unlocking Your Device:

  1. Align the combination wheels to your pre-set 4-digit code.
  2. Press the release button or mechanism on the lock body. The lock head will disengage from your device.
  3. Carefully remove the lock from the security slot.

Maintenance

To ensure the longevity and proper functioning of your Targus DEFCON 3-in-1 Lock, follow these simple maintenance guidelines:

  • Keep the lock and cable clean and free from dust and debris. Wipe with a soft, dry cloth.
  • Avoid exposing the lock to extreme temperatures or harsh chemicals.
  • Do not force the lock mechanism or combination wheels. If they feel stiff, a small amount of graphite lubricant can be applied to the moving parts.
  • Regularly inspect the cable for any signs of fraying or damage. If damage is observed, discontinue use and replace the lock.

Troubleshooting

If you encounter issues with your Targus DEFCON 3-in-1 Lock, consider the following:

  • Lock Not Engaging: Ensure you have selected the correct interchangeable head for your device's lock slot. Push the lock head firmly into the slot until you hear a click.
  • Cannot Set Combination: Make sure the lock is in the unlocked position before attempting to reset the combination. Ensure the reset button is fully pressed or the mechanism is correctly rotated during the setting process.
  • Forgotten Combination: Unfortunately, if you have forgotten your combination and did not record it, there is no master key or override for this type of combination lock. The lock will need to be replaced.
  • Stiff Wheels/Mechanism: Apply a small amount of dry lubricant (like graphite powder) to the combination wheels and the lock mechanism. Avoid using oil-based lubricants as they can attract dust.
