Snaps are common closure devices in clothing. They are a quick and easy way to close a jacket or pair of trousers. Sometimes the snap is in the wrong place and must be removed. Whether the snap is a post type or prong type, a few turns of a screwdriver will pop it apart in no time. The key is to take your time and be conscious of the fabric to avoid ruining it.
Use a clean, small flathead screwdriver and wiggle the tip between the snap and the fabric.
Rotate the screwdriver a quarter turn to create a small gap between the snap and the fabric.
Rotate the screwdriver so it is flat again between the snap and the fabric, and move to the adjacent part of the snap. Repeat step 2.
Work your way all the way around the snap, gently prying it loose with the screwdriver. Take your time and try to avoid damaging the fabric. Depending on the type of snap, there may be a small hole in the fabric where the snap post was inserted. You can cover this easily with a patch.
If you are not concerned about the fabric and simply want to remove the snap, a pair of wire strippers will work. Open the jaws just wide enough to fit around the snap. As you close them, make sure the sharp edges are placed between the snap and the fabric. As you squeeze the tool closed, listen and feel for a small pop to indicate the prongs have released.
