Hey all,
Recently acquired a '08 IS250 Sports Luxury. Currently have one key fob and grabbed one from a locksmith for me to program via GTS Techstream.
Current problem presented is that once I begin registration, no beeps or anything to acknowledge the existing key (is registered and working) for me to continue the procedure for programming.
I ran through diag and saw this code (B2784) but uncertain on next steps. Do I replace the entire harness or is it simply a blown fuse?
Any guidance is much appreciated.
