Question: how to reset the combination
Document: The lock works as desired. I have had no problem with it. It was easy to set the combination, and easy to use.
It works. Easy to set up and it worked. The combination is a little harder to use than competitor products.
This lock is quick and easy to use. The combination with quick release button is a useful feature. It is much faster than the key.
It's a good lock, and I use it daily with no problems. Just don't forget your combination! It fits perfectly in the slot on my windows PC.
Utterly worthless because, even with the combination scrambled, pushing the button rotates the doohickey enough to pull it out of the laptop - I mean it rotates just slightly less than it does when the correct combination is entered.
Easy to set combination, works well for a college dorm room. As a college student, I definitely recommend it as an added layer of security. Additional case is required- use mac locks for that product
I love that this is a combination lock. I don't have to worry about keeping a key. I also like that I don't need to install a small mechanism on my computer in order to use it. I haven't had to take it on the go yet, but I'm sure it won't be difficult.
Once I figured out how to set my own combination (there were no instructions in the box showing how to set the combo; they only showed how to physically install the lock onto the laptop), I immediately liked this lock. It would be good for those who have their laptop in a dorm room, or use it at school or in public places.
I am an incoming college student and this laptop lock serves my purposes nicely. The combination lock is easy to use and DOES NOT FREEZE! In other words, if you choose a wrong combination, it does not permanently lock. That's a concern with some of these locks, but this one doesn't have that flaw. It fit my ASUS laptop perfectly and I highly recommend it.
This lock is not made to defend against a dedicated thief with lots of time/tools with which to steal. Rather, it's made to secure the laptop against a casual "grab and run" thief. For that purpose, this lock works just fine. The locking mechanism fit snugly in the Kensington Security Slot of the laptop. Once the combination was scrambled, the locking apparatus remained locked. It works as designed, and I have no complaints.
Answer: There is a screw (with slot) at the end of the lock housing.  It is in the up position (12 o'clock) for normal operation.  rotates the lock to the correct combination and push the black button to open the lock.  While holding the button down, turn the screw slot to the three o'clock position.  I don't remember turn it clock wise or counter clock wise.  After turning the screw, rotate the combination to the new number and then rotate the screw back to 12 o'clock.  release the button and rotate the tumblers.  The new number should be set then.  Good luck.
