Does your electronics warranty cover theft?

I don't think so but it might I definitely know that your insurance covers electronics and they do cover theft

Store warranties generally do not cover theft. They will repair or replace the item depending, but they will require the defective item first. Check your home owners or renters policy. Many policies carry protections for theft even if the theft did not occur at the residence.

Your homeowners insurance would cover thefts

I didn't think so. Covers labor cost and repairs. I'd unable to repair, it will ne replaced.
