Possible defects in the zipper on the backpack
In the event of a breakdown, it is very important to determine the type of problem. The algorithm for further actions depends on this.
Lightning is a multicomponent mechanism in which any of its elements may break or become unusable.
Runner
If the castle is "parted" from the edges, most likely, the parts of the slider have expanded. You can gently squeeze it on the sides with pliers.
Important! You can not repeat this procedure, as well as compress the slider in the middle. This will lead to its final breakdown.
Battlements
If the lock is fastened tightly, it is enough to lubricate it on all sides with special compounds, pencil, soap, and a candle.
The cause of the “divergence” of metal lightning in the middle is damaged teeth. They need to be leveled and pressed, knocking with a hammer. In case of loss - replace with similar ones, having separated the teeth of a suitable size from another lightning and installed in empty places.
If the zipper is plastic, the fishing line will help. At the place of the dropped parts, we make stitches equal to the size of the teeth and fasten with a lighter.
Important! All the above methods of resuscitation of lightning help only for a while. If none of the tried and tested methods for fixing defects helped, you will have to change the entire lock.
Braid
If the zipper comes off the backpack, it is sewn (preferably on a sewing machine). If the base is frayed and swung, strengthen with molten plastic, Moment glue, nail polish. The composition is applied, pressed, allowed to dry.
Zipper replacement
If these manipulations with the clasp did not help, the issue needs to be decided radically. So, the lock will have to be replaced with a new one.
To maintain the functionality of the backpack, the work needs to be done efficiently and reliably. Therefore, the services of professionals will be required.
Reference! In order for the castle not to fail, you can contact the atelier for tailoring, workshops, shoe repair centers that provide metal repair services to replace it.

The wizard will remove the defective clasp, pick up the accessories of the required size, insert it into its original place.
The cost of replacing individual components is usually low, the lock completely - significantly higher. It includes the costs of accessories, the wizard’s bid, other expenses.
Reference! The specific prices and terms of work can vary significantly due to the complexity of the cut of the product, material, and the current workload of specialists.
Is it possible to replace the zipper yourself
If there is a desire and appropriate practice, you can fix the zipper yourself.
Depending on the identified defect , improvised tools, a sewing machine, a new lock or its elements may be needed.
If the item is expensive, made of dense material (including leather), it is better not to experiment.
Important! Repair work on the backpack is characterized by limited access to the lock mechanism. Since it is securely sewn or hidden by other parts of the accessory.
In such conditions, correct and accurate replacement is problematic. And household machines do not have such a firmware ability as production ones . It is better to entrust your choice to professionals with experience and special equipment!
