I just traded in the Lexus GS350 for a used 2022 Lexus IS 350. The car only had 8000 miles on it, but it came with just one key fob. I know I'm probably being paranoid, but I would sleep better at night know that the other key fob has been deleted from my car. So I want to get my key fob code changed. Is that something only the deal or locksmith can do, or can it be done with techstream? Ive seen alot of videos on how to program a new blank key fob with techstream, but not how to reprogram the original key fob.

 

did you get around making a second key?
