With quality and a price that’s hard to match, Anvil locks are a great answer for your security needs. ◆Make sure your luggage isn’t left unlocked by the TSA. Our locks use a special design that requires baggage inspectors to relock them before removing their master key. ◆Last but not least, all our locks are backed up with a warranty which shows our confidence in the craftsmanship of our product. The preset combination is 0-0-0 and can be changed to your personal combination by following these steps:  Set the combination to 0-0-0. Make sure the cable is firmly locked into the lock body. Press down the combination setting button with a flat head screwdriver or other similar tool and rotate it 90° in the direction of the arrow. Align the numbers to your desired combination by turning the dials. Rotate the combination setting button back to its original position. Your new combination has now been set. You may change your combination and reset your lock by following the above steps as often as you like. Simply enter your personal combination into the lock for step 1 instead of 0-0-0. Tips:  For security reasons there is no reset code for our locks. Please carefully memorize your combination, write it down or take a picture of it.
