If you still know the combination, an old combination lock is worth keeping or donating, because it works for years. If you have lost the code, you can often reset it, look it up, or cut it off, then reuse, donate, or scrap it. Either way, a metal lock does not belong in the trash when it still has use or scrap value.
Locks pile up after school years and gym memberships end. Here is how to put yours to good use.
Do You Know the Combination?
If yes, the lock is good to go. Keep it for a locker, gym bag, shed, gate, toolbox, or luggage. A working lock you already own beats buying a new one. If you have several, set them all to a combination you will remember (see below) and stash them where you need them.
Lost the Combination?
- Look it up. For brands like Master Lock, you can often recover the combination from the maker using the serial number on the back, usually with proof you own it.
- Reset it. Many newer combination locks are resettable. If yours has a reset lever or hole, you can set a brand-new code. Check the brand’s instructions.
- Cut it off. If all else fails, bolt cutters or a locksmith will remove it. After that, recycle the metal.
Donate Working Locks
Schools are the best home for spare locks, since PE classes and student lockers always need them. Gyms, community centers, and Buy Nothing groups take them too. Reset the code first if you can. This pairs well with sorting old keys and old key fobs.
Recycle or Repurpose
A lock you cannot open or reuse is solid metal, so a scrap yard will take it. You can also repurpose locks as zipper pulls, rustic decor, or a “love lock” keepsake. For more, see our declutter and recycle guide.
