At some point or another, you'll probably need to use a combination lock. These can seem a little tricky if you've never opened one before, but don't worry! We'll walk you through the process of opening a 3-digit lock that has 3 dials as well as a circular spinning lock. We'll also show you what to do if you've lost the combination or need to reset...
Spin each dial to enter 3 numbers if you have a 3-dial lock.
Depending on your lock, this might mean that you line up the combination with a marker line on the wide-flat side, or you spin each of the 3 dials so the combination is visible on the narrow side of the lock. Then, pull up on the shackle to open the lock.
Some locks have a red or green stripe running down 1 side. When you enter the combination, line up the digits, so the line passes through them.
If your lock doesn't immediately spring up, push down on the metal shackle before you pull it up.
If you're opening a 3-digit combination lock on a suitcase or briefcase, you might also have to push down on a button or latch after you enter the combination.
Turn the dial right, left, and right if you're opening a spinning lock.
Pull down on the lock if you don't know the combination.
Put the shackle on a hook, so you can pull on the body of the lock. This applies pressure, so you'll be able to tell when you're finding the correct numbers of the code.
If you don't have a hook, put your index finger through the shackle and pull up to apply pressure on the body.
Spin the top number slowly until you feel or hear a small click.
Keep putting pressure on the body of the lock and spin the top dial until you feel some tension—like the number is sticky. You might hear a faint click, which means you've found the right number.
It's a good idea to write down the numbers of the combination as you work. This way, you won't forget them again!
Push up on the shackle to apply pressure to the body.
Put your index finger through the curved metal shackle and push up. This takes a little skill—you want just the right amount of pressure, so you can sense when you've caught one of the combination numbers. If you find that the dial doesn't spin easily at all, release some pressure. If it spins too freely, put a bit more pressure on the shackle.
Spin the dial to the right until it catches on a number and add 5.
Keep applying pressure on the shackle while you do this. Stop spinning the dial to the right when it feels like it gets caught on a sticky number. Take note of the number and add 5 to it. This is the first number in your combination.
For example, if the dial sticks on 7, add 5 to that to get 12 as your first number. Write this down.
Apply more pressure and turn the dial to the left to find the second number.
Set the lock to your combination and pull out the shackle.
Turn the 3 dials, so the correct combination is visible on the side of your lock. Then, pull up on the curved metal shackle at the top of the lock to open it.
If you've never set the combination, use the factory combination 0-0-0. This allows you to set the combination.
Turn the shackle counterclockwise by 90° and push it down.
Hold the lock so the 3 digits on the side are facing you. Then, turn the metal shackle to the left by 1/4 turn—this is 90°. Push the shackle down.
Since you'll need to keep the shackle depressed, it helps to hold the lock between your thumb and forefinger.
