Hello! It would be helpful to know the name of the product too. However, the issue with the battery cover on any item can be solved in the following steps.

- Make sure the batteries are inserted correctly, respecting the +/- polarity.
- Make sure no foreign material, such as sand, hair, or dirt, is inside the battery cover area.
- Make sure the metal contacts on the battery are aligned with the metal conductors inside the battery compartment.
