Targus PA450U DEFCON KL Notebook Computer Key Lock Reviews

• Changing Combos

  
  By AH5KZ1OBXHFLK on 2006-03-15
  I am a student living in a dorm situation and so wanted some basic protection for my lap top computer. I purchased the defcon cl because it was inexpensive, widely availible, and easy to use. Unfortunately, it has one major drawback, occasionally it decides to change the number combinationss which unlock it. I went to the company website and they suggested trying the numbers immediately around the combination and if that failed trying all the number combinations possible (there are 10,000). Several hours, one blister, and 1787 combinations later, I got frustrated and used a jewelers saw to cut through the connection to my computer (this solution took only five minutes). I would not suggest this lock to anyone who lacks the patience to try trial and error experimentation until they reach the correct combination, nor anyone attending a school with a metalsmithing program.
  
  

• Good product, but...

  
  By on 2001-01-02
  Let me start by saying what I like about this device: it is relatively light, and works flawlessly both as security against and as a deterrent to anyone trying to walk off with your notebook. With this device, I feel safe leaving my $3000+ Sony Vaio sitting in the library for an hour while I go grab lunch. It takes 20 seconds to lock, and 20 seconds to unlock, and has been compatible with every notebook I've tried it on.

  That said, the device is not without its problems. Firstly, the device is HYPER-sensitive to motion. If one puts the device into motion-detection mode, it is very difficult to disarm (i.e. to rotate the combination dial) without setting off the alarm. What's worse yet is the 110db warning beep it lets out every time it detects even the slightest bit of motion, meaning that even if you are skilled enough not to set off the full alarm, you are going to have a rather embarassing time disarming it should be in any sort of quiet setting. In short, it is virtually impossible to use the motion detector feature in anywhere you might want it, like a library, since your neighbors will not likely be receptive to a series of 110db warning beeps. Another problem with the device is that there are only 1000 possible combinations. While this sounds like a petty complaint, it is significant -- if you plan to leave your notebook unattended for an hour or two, it is not difficult for your local sticky-fingers to run through all possible combinations before you get back. Let us hope no one is this daring, however. My final complaint about the device is a minor one -- I don't need a 110db beep to let me know the device is on.

  Basically, Targus could fix most of the problems by having two volume levels for various warning beeps; instead, though, we have to suffer through these things at the same ear-piercing volume as the alarm.
  
  

• Lock changes combination by itself - Do not buy

  
  By A2F39UV9SZLT80 on 2006-09-03
  I have been using this lock for a few months without changing the combination. Suddenly I could no longer open it as it appears that the lock has changed its combination by itself.
  
  I called engineering in the hotel I was staying in to help me. It took them less than a minute to cut the cable with ordinary pliers.
  
  
  

• Sturdy and User-Friendly Notebook Lock; Highly Recommend

  
  By A27OP2FCPC7A7X on 2005-08-31
  Please note that this review is for: "Targus PA410U DEFCON CL Notebook Computer Cable Lock." It is a four-digit combination cable lock and does not use a key or have an alarm (as some of the other reviews seem to suggest).
  
  Great Aspects:
  
  This Targus Notebook Lock does its job well and is relatively small and light. There are 10,000 possible combinations and an "anchor plate" is included to create a "secure object" if you are usually using your computer in an area without such stable objects. The 6' cable itself is pretty strong and would take quite some time to cut. The lock can swivel/pivot when locked into a notebook, making it easier to move the notebook and keeping the cable from getting entangled with itself or other things. Re-setting the combination is simple and the lock is very easy to install.
  
  Downside:
  
  Obviously, really determined thieves are going to be able to work thier way around the lock, either by destroying the computer's casing on the side the lock is attached (particularly for plastic-sided notebooks), guessing the combination, destroying the secure object, or cutting through the cable. Provided, most of these actions will take some time (and probably make considerable noise) but the lock is a deterent to theft, not an invincible bastion of security. Use a little common sense with your laptop and don't feel that the lock will save your computer from everything. The price of this lock isn't particularly cheap but it's probably worth the price.
  
  Summary:
  
  This notebook lock should satisfy the security needs of almost all notebook users. The price isn't excellent but, then again, it's also a very good lock and most people probably wouldn't mind paying a few extra bucks for a lock that will actually work well. This is about as good as it gets for general notebook locks.
  Highly Recommend.
  
  

• VG if u want monitoring help, poor as a complete 'guardian'

  
  By A1NZR5TI1FGHQA on 2005-06-14
  Let me begin by saying that I don't do many product reviews at all, but I felt after buying and trying this product, I should. Mainly because it would suffice for some and not for others. I feel that's when product reviews are most important. Since there are only 5 reviews up to this time, I'll consolidate those and annotate some comments on top as well.
  
  Pros:
  1. Manageable (5"x2"x1.5" and doesn't weigh alot)
  2. Compatible with many if not all recent laptops
  3. Very easy to lock and unlock, especially if you leave the dial just a few digits away from your combination
  4. While the motion-sensing warning beeps are distinct, they are by no means 110dB like what this other user mentioned, so they wouldn't bother somebody across a large room. If a normal conversation is 60dB, these warning chirps are around 45dB, and VERY brief at that.
  5. There are 4 digits to the combination, which means a full 10000 combinations. The '999' combinations the other user mentioned relates to a previous model, not the PA400U.
  6. One user mentioned that there was a 110db beep to let him know the device is on. That's b.s. There are a couple chirps, and then a red 'status' LED blinks to let you know the alarm is activated.
  7. The alarm is distinctly louder than the chirps, so people around should figure out that it's an alarm.
  8. Alarm goes off if cable is cut.
  9. Movement of the device sets off 'warning chirps' and there is a red LED light that gives thieves the correct idea that it's an alarm. (In fact, because the LED flashes if the device is locked even if the alarm itself is not set, it's feasible to place the device just on top of the computer, that alone maybe deterring a couple would-be thieves.)
  10. The 'warning chirps', albeit without a melody (it's monotone), are no more irritating to others than a cell phone.
  
  Cons:
  1. Hypersensitive to motion, so you can't really use it outside if it's windy, it'll almost surely go off. In fact, the user who said that its own beep causes the alarm to go off, I find that to be hyperbole. But to give an idea how sensitive it can be, there are times when I have set it on my desk with alarm activated, six inches away from the keyboard -- when I press the 'backspace' key on my keyboard hard enough, the warning chirps can go off. (Incidentally, to give an idea what sets off the warning chirps, when I shake the device, I can hear what sounds like a thin metal disk that is being balanced horizontally when you lay the device flat. When you move the device, the disk is disturbed from its equilibrium position, and that's what sets off the warning chirps. That's also why some users may have mentioned that it seems so hypersensitive: after I set the alarm, and set the device on the table, the disk inside is still vibrating a bit, so typically there is some 2-4 seconds of chirping immediately after you place the device on the flat surface.)
  2. As much as the manufacturer believes that it is 105dB, and as far as information I gleaned from the internet suggests that a lawnmower is 90dB, this device is nowhere near 105dB -- nobody will blink twice if you were in a noisy bar. If a normal conversation is 60dB and a lawnmower is 90dB, the alarm on this thing is perhaps 70-75dB.
  3. The warning chirps would likely bother a stranger at the next seat, or in a library.
  
  Note on who should buy:
  First off, the user that said his laptop was stolen, I believe it, especially if your laptop case is made out of a flimsy plastic like my early-model Dell Inspiron is, a thief could easily use his feet as leverage and just rip it off. If I were in an unmonitored room with a 200 lb stranger, I definitely wouldn't leave the building for 30 minutes without taking the laptop with me. In that sense, I COMPLETELY disagree with the user who said he'd feel safe leaving his $3000 Vaio in the library for an hour while he grabs lunch.
  
  I completely agree, however, with the users who said it works as a deterrent. I believe it is a particularly effective deterrent if (a) there are other people in the room, because it does make a noticeable noise that would bring attention to the thief, and/or (b) you're in the room up to 100 feet away. If you're a guy like me that is super-cautious with his laptop, always looking over his back in a cafe that it's gone, this device is very effective. You set it, and then you can mingle with friends or acquiantances in the same room or within earshot without issue. (For example, with it, I have much less problem in cafes going on extended bathroom breaks and bringing my laptop with me to the bathroom drawing weird stares.) To be quite frank, I believe the best kind of places to use this would be a hotel lobby, an airport, and ESPECIALLY a cafe.
  
  VERDICT: In short, if you'd pay a premium for a device that genuinely looks like a laptop alarm (thus deterring thieves), and you'd pay for a moderately loud distinctive sound to tell you that somebody is attempting to take your laptop (like I would) or a sound loud enough where others nearby would likely notice the theft and be able to ID the bugger later, then this device is good. Otherwise, just get a standard cable combo lock if it's cheaper.
  
  Although one user said his uses a key, I bought my PA400U in June 2005, and it is strictly a combo lock.
  
  Tip to Targus:
  Provide a couple volume levels for the beeps
  
  
• Combination mysteriously changed
  By A2XPFZ834PQ8GN on 2006-05-01
  I had been using the lock for my laptop for the past 4 months without any trouble. All of a sudden, today, as I went to pick up the lock, which had been left untouched in the open position overnight with my combination in it, it decided to change combinations by itself. So it was in the locked position but the combination is still the one I had set. I tried so many combinations 'around' mine but obviously there are so many different possibilites. The fact that I even have to try to think of what combination my lock decided to change itself to today makes this a lock I can't rely on!
  
  
• Too Sensitive to Motion
  By on 2000-11-10
  Mine goes off with little or no motion. It almost seems that its own "beep" causes enough motion to make it "beep", which causes it to "BEEEEEEEEEEEEEEEEEEEEEEEP"..... So I don't set it. The saving grace is that even if I don't set it, the alarm always goes off if the cable is cut. The thinness of the cable plus its retractability make it easier to travel with than the thick cables.
  
  
• Not For Apple ibook
  By A13Z3US6I8IOS9 on 2005-09-08
  DO NOT BUY IF YOU HAVE AN iBOOK!! It slides in easily, but it is almost impossible to get out. I had to call their support line and they told me to apply pressure in the upper left corner (lower right corner if the lock is upside down). Even after doing that, it took me 10 minutes before I finally got it out. When I called, the guy asked me if I had an ibook before anything else. He then told me that they are tight in the ibooks and people have trouble getting them out. It is not worth the struggle if you have an ibook. I highly do not recommend this product for apple ibooks.
  
  
• Great Locking System
  By ABO405O29CU1O on 2001-02-28
  I am very happy with my cable lock. Although it does not make your computer equal to Fort Knox, it will at the very least slow a would-be theif down. I can hang my 8lb laptop off of it, and bounce it up and down with the cable, and it holds firm (trial conducted over my bed, a heavily padded surface). I like how the cable swivels around the actual lock to avoid the cable kinking, and becoming cumbersome. I also like the fact that it is a key operated system. Although combinations are quicker, they can be hacked in about 5 minutes of trying, and slipping a key in the lock and giving a quick turn can't be any simpler. Just remember to keep one key in a safe place, and write the key serial number down somewhere so a replacement can be found. For the money, I don't think there is a better security option for notebook computers, unless you spend the ... on a doberman puppy, and train it to attack computer theifs. But that would be hard. Buy this lock system, and it could save you ....
  
  
• Once it's on it may never come off.
  By A3K48EFHJMWXZI on 2006-08-26
  While I don't have any evidence to refute the package claim that it "attaches to any notebook", once attached to my son's computer it was almost impossible to remove. It took 10 minutes to get it off and we were pulling so hard I thought we would damage the computer. We will be returning it. Not recommended.
  
  
• User from New Jersey
  By on 2000-06-21
  This product is very compact and easy to use. You dont need to carry a lengthy cable. This also has motion sensor which is very useful especially in hotels, and airports. The only problem is that there are only 999 combinations of lock which could be easy to break.
  
  
• Lock easily broken
  By A3NSPBKHVAFS39 on 2005-02-18
  I just had a notebook stolen that was "locked" with this lock. The thief gave it a good yank, and the metal easily broke off. I suppose it may work as a deterrent, but don't fool yourself into thinking your computer can't be stolen.
  
  
• Never trust this product.
  By A35XEYIBJT7ZES on 2006-11-18
  I bought this product less than a year ago. 2 days ago, I locked my laptop and tried to unlock it. But I couldn't. It was somehow messed up and the combination did not work. I HAD TO CUT IT!!! I don't know how it got messed up but I'm sure that it was not study enough to last long.
  
  
• Targus PA400U DEFCON 1 Ultra Notebook Computer Security System
  By A3LOFKKMNZTJAF on 2006-09-07
  I had this for approximately 2 years. It worked fine for couple of months but suddenely started to activate the alarm without any disturbances. One day I left my laptop attached the alarm in my office for about half an hour. During this period, the alarm was activated and I was embarrased to face my office workers. This is without increasing the sensitivity of the alarm. I sent it back to Targus and they were nice enough to give me a new alarm. But after several months, it started the same problem.
  So, now I am afraid to use this security system with my laptop. But I did not face problems like changing the combination by its own. You can use it without the alarm activation (i.e: without batteries) but the cable is so thin, it is not recommended to protect any valubles.
  
  
• Have an iBook? Don't buy this lock!
  By A3BP1GBV2VPHYK on 2006-10-18
  I posted a review two weeks ago, but it hasn't appeared, so I'm trying again...I bought this lock two years ago. It has always been difficult to remove. (Note: despite what some other reviewers seem to think, it does NOT have a motion detector - that's a different lock.) Recently, the lock decided to remain firmly inside my iBook, despite my efforts to remove it. After a fruitless call to Targus's customer support, I finally got it out. That took over 30 minutes of struggle. My next step was going to be purchasing a hack saw. Apparently, the Targus lock is not a good fit for iBooks. I'm going to send mine back and demand compensation. If you own an iBook, I strongly suggest you buy a lock made by someone other than Targus.
  
  
• Dont buy
  By A5Z9V84DDHS3Y on 2007-10-01
  Everything that happened to other people happened to me. I have an Ibook, used the lock for about two months total. I bought it last year and used it for the month of October before I started to just lock my office. During that month I never set the lock to any combo. It remained at the 0-0-0-0. I used it for one month this year and it is already broken. I was having trouble with it for about two weeks before it final broke. That brings by total time used to six weeks of normal use. I would not recommend this product to anyone and if I was able to get te lock out of my comp I would not even sell it or give it away b/c it is worthless. [...] I would give this item 0 stars if it were possible.
  
  
• Does as advertised
  By A3PB65ID19UGRZ on 2005-10-16
  This thing does what it is supposed to an nothing more. I don't feel extremely safe leaving it unwatched even with this on, but it certainly makes my laptop less appealing to steal. If someone really wants you're notebook, this thing will only slow them down. So don't swear by it. I feel this item is slightly overpriced, but so are all laptop locks. No real problems with this item, just nothing great either.
  
  
• A better mousetrap
  By A38PLWYVUL3OPM on 2005-12-13
  This does exactly what it is supposed to do. It is light, easy to pack, easy to use, and probably difficult to crack.
  
  (Though would-be PC pilferers haven't tried taking a hacksaw to my cable lock so I cannot comment as to its ability to withstand saws, blow-torches, or any other criminal's tool.)
  
  Other reviewers baffled me as mine is as described by Amazon. There is neither an alarm nor batteries. Why bother with an alarm if the PC is locked with steel cable? Seems like overkill?
  
  
• Don't Buy "d
  By A2H2ZU5W6SZ85K on 2008-01-06
  on Jan.6,2008 I bought my son a "Defcon CL" combo cable lock. I brought it home ,picked a combination and tried it 3 times and it worked all 3 times!! I then went and put it on my son's computer and guess what? I can't get it off. I guess it changed the combination on it's own. WONDERFUL!!!!
  I then read all the wonderful reviews about this lock. I hope there are people who will read this before they buy.
  
  
• Lock jammed, so I had to break it off
  By A1F1ETT6Q22XMR on 2008-06-02
  I just finished breaking this lock off my laptop because it somehow jammed. My laptop was securely locked in my hotel room, keeping even a person with the combination from removing it. After a couple of quick blows with a ratchet handle, the lock itself broke apart. Once I took the end off the lock, it popped right off the laptop. See my photos above of the smashed lock.
  
  When I bought this, I joked to my buddy that it would now take a thief 30 seconds longer to steal my laptop. If only I had realized how right I was. The only reason I spent half an hour trying to remove it was because I was trying to save the lock. I'll call the manufacturer to ask for a refund tomorrow. If they don't give me one, I'll take it back to Staples, where I bought this just six weeks ago.
  
  
• Do Not Buy!
  By AM1ITCWUY7N4T on 2008-03-14
  Heed the warnings from the reviewers that indicated "mysterious combination changes", especially if you own an Apple laptop! I bought this for my son to use in college and after one week of use he called to tell me that the combination no longer worked!!!!
  
  
• Exactly same as the description
  By A2YHEPKXV821IP on 2006-03-03
  This is the best lock you can find for laptops, but I am still not very confident with it. It looks flimpsy but better than others.
  
  
• Great video lock
  By A38ZVZYRDUZE9E on 2007-10-18
  This lock was one of my purchases to go along with my new computer. I live in a dorm room and kids now-a-days cant be trusted. This lock works great, locks into a provided VGA thru cable. The only way they will steal this is by cutting the cable with a strong pair of clippers or ripping out my video port, or if they know the combo. Otherwise great lock, I feel sure that they wont be able to walk out with my computer.
  
  
• Heed the warnings!
  By A16PZMOUQ8D7BH on 2008-03-16
  I set the new combination. It worked fine twice. The third time it got stuck in my ibook. I had to cut it off. Do not buy this lock.
  
  
  
• Mixed UP Reviews - Try This.
  By A3D8VXLAZGTIH on 2008-06-06
  Not one single review here is about the actual item for sale. When I clicked on the product reviews for this item. The item is the Targus PA460U DEFCON Authenticator - Black [Electronics] Which in fact has nothing to do with combination locks, cable locks, Or for that matter any kind of locking device other than a programed security device which locks down your computer so no one can enter your files without you being present. Unless of course they have the same finger print as you. It can also work for more than on computer at a time if for save you have two linked together in your network and prefer you children (example) or whomever to have acess to your computer when you are not present. All I can say is that mine works great and I very happy I have one.
  
  
• laptop lock with combo changes on its own
  By A1VNFRX2IV0YQL on 2008-08-30
  Targus laptop lock with combo lock can change combonation on its own. I am in a dorm and decided to keep my laptop locked while I was not in my room. One day I could not get the combo to work. When I called Targus customer service they told me sometimes the combo slips on its own that I needed to try combos with surrounding numbers to the combo I had set weeks ago. It took hours of work, but after many tries found that the last combo digit had changed by one number drop. I am now going to purchase a lock with keys-never again will I use the combo lock.
  
  
• Krap with a capital "K"
  By A28U1V4LIW5HB1 on 2008-09-03
  My boyfriend has been using this lock daily for the past 4 months to secure his laptop at work. Today it decided that the combination he had set was inadequate, so it reset itself. Now we cannot get his laptop off his desk, which defeats the purpose of having a portable computer. We strongly suggest buying a lock that unlocks via a key. Do not purchase this lock.
  
  
• Lock and secure
  By A38WJKB6YULQ6J on 2008-02-10
  For users that travels a lot 100% recomended most cases when you need leave your notebook in some conference room or room hotel.
  
  
• Do not buy
  By A1TEEBGRM13VJ1 on 2008-02-27
  I just purchased the lock recently. The lock is very hard to put on and take off. Even with the right combination on you have to pull a bit hard at the cable. Which makes it pretty hard to take off. The price of the lock is cheap, but you are better off buying a more expensive one.
  
  
• Missing Features that are present in cheaper locks
  By A19FCJXCRRHUV0 on 2008-04-04
  I'm using the cable for about a month now and haven't encountered (yet?) the dreaded "sudden change of lock combination" so many people here encountered. Yet, I am missing a feature that I had in a cheap clone lock looking almost similar to the Targus Defcon CL. See the black bulk that closes the cable loop ? On the clone it was actually a metalic disk with a hole (similar to the one you find in the laptop). This allows you to lock the cable to itself when going away with the laptop. You might think noone would steal a lock cable because they don't know the combination and would be useless, but it happens (especially because they get a better chance to steal your laptop later on). This forces you every time you need to walk away with your own laptop to have to carry the cable lock with you.
