How do you open my gx b0709 safe you locked keys and manual inside?

To open a GX B0709 safe without keys or the manual, you can try using the factory reset option if available, which might allow you to set a new combination. If that doesn’t work, consider using a professional locksmith experienced in safe opening. Alternatively, you could contact the manufacturer for guidance on accessing your safe. Avoid using force, as this can damage the safe and its contents.
