• Conveniently Uses The Security Slot Already Built Into Your Notebook
• Sturdy Six Foot Cable - Any Attempts to Remove It Will Damage The Computer, Preventing Resale and Discouraging Theft
• Comes with 2 Identical Keys

The DEFCON KL (Key Lock) is a sturdy locking device featuring a 6 foot 6 inch steel cable, with a pass through loop on one end, and lock on the other end. Any attempts to remove it, will noticeably damage the computer, preventing resale and therefore discouraging theft. The lock utilizes the security slot already built into your notebook computer, and attaches to the notebook using the same method as the DEFCON CL (Cable Lock). The Key Lock also ships with 2 identical keys, giving you the peace of mind of a back-up key.

Bought this for my daughter's laptop at college. It works well and she loves it. Easy to set-up.

I am a college student and recently bought this lock for computer security. My sister, who is also in college, bought one as well. Both of us have now had to saw this lock off our computers because it has suddenly changed the combination and became locked on my computer, keeping me from taking it anywhere. The only solution Targus gives is to "try every possible combination." There are 10,000 possible combos. This is an extremely terrible product, do not buy it.

I purchased this product (from a different retailer) in June 2008. The combination that I set worked fine a few times and then suddenly stopped being recognized by the lock. I was able to use the lock less than ten times before it failed. I owned it for less than one month before the cable lock got stuck in my notebook computer; the lock is still stuck in there now.

Just so there will be no confusion on the product... Here is some information from the original packaging: "NOTEBOOK SECURITY Defcon CL combo cable lock"..."Targus". In the lower left corner is the model number PA410U.

This lock is the worst lock ever made, the lock resets itself so you cannot unlock it. To remove the lock you have to cut the wire (super easy) and saw the lock off. In the process damaging my computer. This product should be taken off the market.

I had the same problem - lock "magically" reset itself and the combination I had been using for 1 year no longer worked. Fortunately, I was able to cut it off in 3 minutes with a hacksaw. Unfortunately, I am out $10 for the hacksaw and $30 for the lock. Here are the instructions for cutting the lock off that Targus doesn't post on the website, but will email to you:

Obtain a hacksaw from a hardware store or similar location. Make sure that it has a high-speed metal cutting blade. After stabilizing the tail of the DEFCON CL in a vise, saw through the head. Do not try to saw the teeth of the DEFCON CL, it is much easier to begin sawing at the gap next to the cable attachment ring. After sawing all the way through, you will be able to take apart DEFCON CL and remove it from the notebook. This should take an average of 10 minutes.
