I have an 05 LX470 with no master key. 3 local locksmiths have not been able to get a key to work! Will your ECU eprom fix my issue? I'm willing to pay for the part and shipping.

No. I'm pretty sure after 2003 you can use Techstream. If you have Techstream you just need a passcode to reset the ecu. I had to do it this way for my wife's 05 GX470. I also think that the immobilizer ecu is seperate from the engine. It also has a different chip.
If you are able to get access to Techstream and need a passcode let me know. I had to buy 5 passcodes and only used 1. If you were local I could show you how to do it
Unfortunately, I don't have Techstream. Thanks for the offer to show me how to do it as well. I'm in Las Colinas TX.
Great videos. Thanks for taking the time to educate us on this!

Have any of you received your eeproms yet? Anybody installed one?
I've got another ebay ecu coming next week. May try a swap thing for people who aren't comfortable with changing out chips
If anybody gets a chance to look at their ecu in model years 99-2002 please post part number of ecu.

I received mine over the weekend, but I've been out of town. Have a pair of pre-cut keys on the way from 1010 keys. Once everything is in hand, I'll do the swap and report back.
Cracked open ECU but didn't install the chip yet. The layout of the board on my MY2000 is different than the video and so is the location of the IC900 chip.
Yup. Just in a different spot.
I finally had the time and the right tools to install my chip from @Mauser . I picked up one of these 862D+ rework stations off Amazon, a flux pen, some solder wicking braid and some solder. I went a little further than the videos above, though. After removing the original chip, I cleaned all of the pads, applied some flux and tinned the chip. Install was easy and the programming was exactly as shown in the video. I'm so glad to finally have more than one key, be able to use my remotes and EDC the Yota MD titanium key instead of the valet key.
Big thanks to Mauser for doing all the research and making these available. Desoldering and soldering components onto your cruiser's ECU is scary but not difficult. Took about 20 minutes total with no practice and all the extras. Very happy with the results.

@Mauser I can’t believe I’m just seeing this. Are you still offering these chips? I only have a metal key that unlocks the doors, but I lost the transponder keys. It’s been sitting for a long while cause I didn’t want to fork over for a new Ecu and keys.
