<human>:  How can I fix a broken zipper?
<bot>: To fix a broken zipper, first determine what type of zipper you have. If it is a metal zipper, you can use pliers to try to snap the two sides back together. If that doesn't work, you may need to replace the zipper with a new one. For plastic zippers, try pushing the broken parts back together and make sure the zipper is centered. If the zipper pull is still attached but won't budge, lubricate it with wax or soap to help it move freely. If that doesn't work, you may need to remove the broken zipper and install a new one.
