I was programming a Lexus credit card key tonight for my ‘21 LC using TechStream. I have done this before with other vehicles without issue. Everything went well and the new key registered but now none of my fobs will lock/unlock the truck, including the second factory fob. All the keys will start the truck but none of the buttons work. I can even use the fob to change the door unlock (one vs. four) function. It is like the smart key system is deactivated.
What am I missing? What did I screw up?
