Symptoms
- Dials won't move or feel gritty
- Correct code entered but shackle won't release
- Lock was fine last use, now stuck
- Zipper pull lock won't separate
Likely causes
- CommonCombination misremembered or entered one digit offPeople often reset a lock and forget the new code, or misread worn numbers.
- CommonDirt or grit inside the dial mechanismTravel dust works into the gaps between dials.
- PossibleShackle bent slightly, binding in the housingA knock in transit can misalign the small latch.
- Less commonInternal spring or latch failureCheap locks can fail internally with age.
What to do
- Double check the combination against wherever you recorded it (phone notes, lock's box, retailer account).
- Try nearby numbers if you suspect you're one digit off in either direction.
- Wiggle the shackle gently while turning the dials to the code; slight misalignment can bind the release.
- Tap the lock lightly against a hard surface (not hard enough to damage it) to dislodge grit, then retry.
- Apply a drop of graphite or dry lubricant into the dial gaps and shackle hole.
- If it's a TSA lock and still won't open, contact TSA or the airline; if it's your own lock with no way in, it will need to be cut off with bolt cutters.
Tools and parts
- Graphite or dry lubricant
- Bolt cutters (last resort)

When to call a pro
A locksmith can pick or drill a stuck lock if you can't cut it off yourself; a luggage shop can also fit a new one.
