Remote start

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The MESA 4405M remote start system *can* be compatible with a 2005 Toyota 4Runner, but it may require an additional module to bypass the factory immobilizer. Older Toyotas often need this bypass so the remote start can communicate correctly with the ignition system. I’d recommend checking with a professional installer to confirm you have the right setup, as the wiring specifics can get tricky.
