Does a dealer have to service a Prius because of the battery? on 2005 Toyota Prius

A Prius is a hybrid, operating on a battery and gas. The dealer is very expensive for having maintenance performed. Will other repair shops work on a Prius since it does have the battery? Will the warranty for the battery still be honored by Toyota if someone else does do the 5000 mile service appts.?

Having an independent shop will not void your manufacturer warranty. There are classes that technicians take to become hybrid certified, and you can ask independent garages whether they have hybrid certifications.
