Follow this guide to remove and replace a plastic snap (aka snap fastener, snap button, or press button) using a handheld fastener tool.

Before you begin, check the fabric around the old snap for tears or damage beyond a small hole. If the fabric is compromised, you'll need to sew a reinforcing patch before replacing the snap.

If you're installing a brand new snap, check out this guide.

If you're replacing a metal snap, follow this guide instead.

When the snap is installed, the socket and stud will lock together, while a cap holds each of them in place from the other side of the fabric.

Place either a stud or a socket on top of the pin.
If you can't see the pin after placing the stud or socket, the fabric is too thick for the snap. You'll need a cap with a longer pin.

Visually inspect the snap. The center pin should be evenly flattened.
Pull on the snap. The snap shouldn't feel loose.
If the pin isn't evenly flattened or the snap feels loose, use the fastener tool to compress the snap again. If that doesn't fix it, remove the snap and start again.
