Review on 🔑 High-Quality Key Fob Keyless Entry Remote for Lexus GX470 LX470 (2003-2009) - HYQ1512V by Vivek Allen

I was able to program the remote but Techstream kept saying it couldn't communicate with the key. So I took it to a local locksmith who opened it up and told me the chip was the problem. Apparently the chip is not compatible with my 2006 GX470. He changed it to a working one, cut off the key, and off we went. It was still a lot less money than I would spend on a new master key at a dealership, so I'm still happy. However, if the chip was correct, I could program the immobilizer myself and save the $50 he charged me for it. I don't know any details about the chip or what models it will work with. All I know is that it didn't work on my Lexus.
