For luggage, bike and locker locks
Forgot your combination lock code?
Try every combination once, without losing your place. Each step turns one wheel by one click, and this page remembers what you’ve tried.
Drag the lock to look around it.
Step 1 · Where is your lock now?
Set these wheels to what your lock shows
No need to turn it to 000 first: the search starts from right here, one click at a time.
Now trying
000
Opened
000
That’s your code. Write it down somewhere safe, or set a new one you’ll remember.
Every combination crossed off
None of them opened?
Usually one was skipped by accident: a wheel turned two clicks, or sat between two numbers when you pulled. Tap codes on the grid to bring them back, or start over and pull a little harder each time. Some locks also have a reset button or a key; see the tips.

How it works
One click at a time
Counting 000, 001, 002 makes you turn two or three wheels at once every ten tries, and that’s where codes get skipped. This page goes in snake order instead: 000, 001 … 009, then 019, 018 … 010. Every step moves just one wheel by one click.
Start where it is
Set the wheels on the page to whatever your lock shows now and start from there. There’s no need to turn everything back to 000 first.
Nothing tried twice
Every code you mark as “didn’t open” is crossed off on the grid. Close the tab and come back tomorrow: your place is kept in this browser, and nothing is uploaded.
Guesses first
Think it might be a birthday, 1234 or an old code? Add it as a guess. Guesses are tried before the full search, and crossed off so the search skips them later.
How long it takes
| Wheels | Combinations | At most, at 3 seconds each | On average |
|---|---|---|---|
| 3 (most luggage) | 1,000 | about 50 minutes | about 25 minutes |
| 4 (bike, locker, padlock) | 10,000 | about 8 hours | about 4 hours |
| 5 (some cable locks) | 100,000 | about 3½ days | about 1¾ days |
The estimate on the page learns your own pace as you go. Before a long search, read the tips: many locks have a quicker way out.
