What You'll Learn
Realign the zipper by taking it apart and putting it back together
If the zipper slider is damaged, you can try to realign the zipper by taking it apart and putting it back together. This method works for zippers with metal stops at the top. If the stops are plastic, they cannot be removed and put back together without breaking them.
First, use a pair of small-tipped pliers to gently remove the stops at the top of the zipper. Then, pull the slider off the zipper. Next, press the teeth of the zipper together so they are alternating and locked into place. Put the slider back on the zipper. Finally, reattach the stops by squeezing them back into place with the pliers.
If the zipper teeth are bent, you can use your fingers to gently straighten them. If the teeth are made of metal, you can also use pliers to straighten them out. Be careful not to apply too much pressure when using pliers, as this can damage the slider.
If the teeth have worn down from overuse, you can try painting them with clear nail polish to thicken and restore them. Allow the nail polish to dry before attempting to use the zipper.

Straighten bent teeth with pliers or fingers
Bent zipper teeth can cause a zipper to separate and not function properly. If the teeth are made of plastic, it is best to gently straighten them with your fingers, as using pliers could easily break them off.
If the teeth are metal, you can use a pair of pliers to straighten them out. Make sure to be gentle and not squeeze too hard, as you don't want to crush the slider or make the gap too small for the zipper to move up and down. You can also use needle-nose pliers to get a better grip on the teeth and gently bend them back into place.
If the teeth are severely bent or broken, you may need to replace the entire zipper. However, if the teeth are only slightly bent, straightening them with your fingers or pliers can be an effective way to repair the zipper.
In addition to straightening bent teeth, you may also need to realign the zipper by taking it apart and putting it back together. This involves removing the stops at the end of the zipper with pliers, pulling off the slider, pressing the teeth together so they are alternating, and then putting the slider and stops back in place.
By following these steps and being careful not to damage the teeth or slider, you can repair a zipper with bent teeth and restore its functionality.

Use tape to fix a broken zip
Invisible zippers and plastic zippers are harder to fix. If you have one of these, you may be better off replacing it. However, if you can't get the sides back together, you can always use tape to temporarily fix a broken zip. Sellotape or duct tape can be used to fix a broken zip before trying any other solutions.
If the zip is stuck, gently remove any caught fabric, pulling the fabric and not the zipper. If the zipper is still stuck, use a lubricant like petroleum jelly, candle wax, or a bar of soap on the teeth near the stoppage. You can also try the graphite pencil trick: rub the teeth with the lead of a No. 2 pencil. The "lead" is graphite, which will help lubricate the metal teeth and allow the zipper slider to move more smoothly.
If the zip is broken, you can try to fix the slider itself or realign the zipper by taking it apart and putting it back together. If the sides of a zipper separate and won't go back together, it's often because the slider itself is damaged. Use small-tipped pliers to remove the u-shaped stops at the end of the zipper. Pull the slider off of the zipper. Press the teeth of the zipper together so they're alternating and popped into place. Put the slider back on the zipper. Reattach the stops by squeezing them back into place with the pliers.
If the zipper pull is destroyed or made of plastic, you will need a new one of the same size. Remove the zipper pull and put back the new one. If the zipper pull is not too worn out, you can try to close it directly on the zipper without removing it.

Sew a new stop with thread
If your zipper stop is plastic or you are unable to reattach a metal zipper stop, you can use thread to create a new one. Firstly, thread a needle with a heavy thread and tie a knot at the end. If you don't have access to heavy thread, simply double up a regular thread and tie a knot at the end of both strands. Pull the thread through the zipper, ensuring the knot remains on the inside of the garment. Next, stitch across the bottom of the zipper where the old stop was previously positioned, creating six or seven stitches to form a new stop. It is important to ensure the zipper pull or slider is above the area you are repairing.
If you are creating a custom zipper for a project, you can sew the zipper ends into your work. This is particularly useful if your zipper is long enough to reach a seam or hem, as you can sew it closed. You can also make a fabric stop for your zipper, which is ideal if you like the look of a fabric stop or if your zipper is not long enough to reach a seam or hem. To do this, cut a small rectangle of fabric, binding, leather, or another material of your choice. Fold it over the zipper teeth and sew it in place while sewing the zipper into your application. This will create a neat-looking stop that blends with your fabric.
Another method is to use a soldering gun to melt two of the teeth together, creating a permanent closure. This method is commonly used for Vislon (plastic) zippers. However, it is important to be cautious to avoid igniting the zipper. Practice on the part of the zipper that you cut off, and gently blow the smoke away from you to avoid irritation.
If your zipper has damaged lower teeth, you can move the pull slider above the damaged area and sew a new stop just above the affected teeth.

Replace the slider
A broken zipper slider can be frustrating, but it can be fixed at home with a few simple tools. Before starting, it is important to identify the type of zipper and the size of the zipper slider. This is important because zipper sliders are made to be compatible with their zipper counterparts. For example, a nylon coil zipper slider is only compatible with a nylon coil zipper.
Once you have identified the type of zipper, you can gather the necessary tools and materials. You will need a new zipper slider that matches the size and type of your old one. You can usually find replacement zipper sliders at craft stores, fabric stores, or online. You will also need a pair of pliers, needle-nose pliers, or a flathead screwdriver to help with the installation process.
If there is a metal zipper stop present at the top of the zipper, remove it using needle-nose pliers. If it is a plastic zipper, you will need to cut the top stop off with nippers. Be careful not to cut the zipper tape; only cut off the very edge of the stop. Then, peel away the rest of the top stop from the zipper tape. If there is any fraying, use a lighter to lightly singe the zipper tape.
Next, remove the old zipper slider by sliding it up to the top of the zipper and then sliding it off. Now, slide the new zipper slider onto the zipper tape, ensuring that it is oriented correctly. Maneuver the slider as if you are parallel parking a car.
Finally, test the zipper to make sure the new slider is working properly. Gently zip and unzip the zipper a few times to ensure that it moves smoothly and doesn't get stuck.

If the teeth of a plastic zipper are worn down, you can try painting them with clear nail polish to thicken them. Allow the nail polish to dry before trying the zipper. You may need to add a second or third layer if the zipper slips down.
If the slider of a plastic zipper is damaged, you can try to restore it to its original shape using pliers. Gently squeeze the top and bottom plates together repeatedly, being careful not to apply too much pressure as this can break the slider.
If your plastic zipper is stuck, first try to remove any fabric that may be caught in the zipper using tweezers or needle-nose pliers. If this does not work, you can try using a lubricant like petroleum jelly or graphite (from a pencil) on the teeth of the zipper.
