EVO ONE will not Program with RFK411

Question

2021 Toyota Tundra H-key, EVO-One installed and working correctly with factory lock-lock-lock. Installed RFK411, no LED on antenna at any time. continuity tested cable, checked good. Vendor suspected bad antenna and exchanged for a new kit. Still no LED on antenna. EVO-One was "preprogrammed" by vendor to be plug-and play, but I have a Flashlink. Connected Module to Flashlink but keep getting "cannot connect" error, so can't read current settings. Module SN 002B04 705689
