If it has an immobilizer (chipped keys) then your SR5 doesn’t have the components and wiring/connectors necessary to read the chipped key to allow the ecm to start the engine.
It would be a lot of work to add the necessary components in order to make your new ecm work with your current vehicle. I’d recommend finding another ecm that doesn’t have an immobilizer. If it helps with your search, for your year only Limited trims have an immobilizer in the ecm.
