Necklace Clasp Won’t Stay Closed.(Reasons and Solutions)

Hey! I finally find the Answer!

What do you do when your necklace clasp keeps coming undone, and no matter how well you fix it, it just won’t remain closed?

Is this a problem that can be fixed in the first place? And why is the clasp not staying closed in the first place?


Why your necklace clasp won’t stay closed?

There are two main reasons why your necklace clasp doesn’t stay closed.

These reasons include:

The clasp might have stuff and fluff that is blocking the clasp from closing or staying closed. You might not notice this immediately, but sometimes, even the smallest amount of fluff could block the fastening action of the clasp by blocking the internal hinges.

So, if the clasp is not working well, you might want to look out for any foreign matter or particles in the clasp. The problem could be something like sweater fluff which can be removed easily using a piece of a safety pin.

Just insert the safety pin piece at the back of the clasp where it attaches to the necklace chain the push the fluff out and through the clasp on the other side. The clasp will be clear in one or 3 sweeps using the safety pin.

A strand of hair or strands could be tangled in the clasp’s internal mechanism as well. Here, you can dissolve the strands in bleach – dip the clasp in bleach in a small container or a soda lid.

The other reason why the clasp is not closing or staying closed could be that the distance between the top and the bottom clasp sections is a tad too big. You’d have to gently hammer or use a clamp to press down on the clasp, reducing the distance and keeping the clasp closed.

Why won’t your necklace clasp be stuck in a pendant?

If the clasp is stuck in a pendant, there could be fluff or hair strands tugging on the clasp and preventing the clasp from working as it should.


Why won’t your necklace clasp won’t open?

The common reason why a necklace clasp would be that the clasp hasn’t been in use for a long time, and now it’s probably rusted or just has too much gunk caked in, which makes it hard to open. You could clean it first using soap and warm water and use a soft-bristled toothbrush to clean it.

If the clasp is still not working properly, add a little cooking or olive oil, let it sit for a few minutes, then try opening it slowly. This often works well, especially if the parts aren’t soldered together.

How to Repair your closed Clasp

If cleaning out gunk, hair, or fluff doesn’t resolve the problem, it may mean that the clasp is damaged. The good news is that there is a chance that the clasp could be repairable. Do this gently, but slowly hammer the clasp as you slowly try to pry it open.

Unfortunately, repairing the clasp might not work as well as you may have hoped, which is why we’d recommend replacing the clasp altogether. Replacing the clasp will, naturally, save you the trouble of a broken or a more problematic clasp, and you get to enjoy the peace of mind that comes with retaining the original necklace.
