GlennL Posted November 26, 2022 Share Posted November 26, 2022 Only had one key for 2008 RX 400h--that's all wife got when she bought it used several years ago--so decided to get another one off amazon. Got it cut, and tried to use the instructions that came with it to get it programming. There were two separate parts of programming steps--one for immobilizer, and another for remove lock/unlock--and neither one worked. Looking around youtube, I finally found an alternate procedure that actually worked for the immobilizer. But I have been unable to find anything that works for the remote part. Has anyone had any luck with this? Quote Link to comment Share on other sites More sharing options...
zieke Posted November 27, 2022 Share Posted November 27, 2022 I bot my 2nd key from a good reputable seller online and figured since I saved some money this way, I would have the dealer program it for me. It works perfectly, and I didn't waste time trying to circumvent the right way to do it. For what it's worth. Quote Link to comment Share on other sites More sharing options...
GlennL Posted December 11, 2022 Author Share Posted December 11, 2022 Thanks for the reply. Ended getting someone with access to Techstream to do it for me - just couldn't figure out a way to do it without that Quote Link to comment Share on other sites More sharing options...
RX400h Posted December 14, 2022 Share Posted December 14, 2022 Automotive locksmiths typically can do everything but I've found that they are sometimes as costly to hire as a dealership. Quote Link to comment Share on other sites More sharing options...
EyesofThunder Posted January 3, 2023 Share Posted January 3, 2023 My son has a XTool D7 and I picked up a couple eBay/Amazon blank keys with fob and had the local Lexus dealer cut and then I programmed them with no major issues. In both keys I had to program it 2x to get it to "take", and then you have to learn the door unlock/lock functions separately. But not a problem. Check with local locksmiths or call local repair shops and ask who does keys and programming for them. Quote Link to comment Share on other sites More sharing options...
