Immobilizer Hacking Lost or New Keys for Lexus Toyota | ECU Replacement Immobilizer Hack

DIY video on how to read your car’s engine computer immobilizer EEPROM to program new keys in the event of lost master keys or a replacement ECU.

This video shows you how to copy or reset the engine immobilizer in your Lexus/Toyota or other modern cars. You can copy or clear the EEPROM chip of all previously stored keys and “virginize” it to accept new keys. When the ECU is first plugged up, it will go into Auto Programming mode, and accept 3 master keys and a valet that you insert into the ignition.

Where is the clip and plug in on Amazon? And what program is used on the laptop?

steve evans says:

Does this work on windows 10 64bit as the i cannot see the 64bit drivers in this version of the as programmer?

john dakin says:

How did you know which chip to read and the number of the chip, i am looking to do Audi – VW cars and i have the xhorse chip reader, just need to work out how to use it, great video thanks

steve evans says:

Can the eprom from the old ecu be swapped onto a second hand ecu . ?

Ramin says:

Awesome detailed video. I have a Mercedes 190SL with 2007 Yaris drivetrain. This car was running with a regular non chip key but since I changed some of the wiring, now I get code B2799 (Immobilizer System). So I have no ignition or fuel. Is it possible to program this ecu to run with a regular key which does not have a chip?

Joshua Wood says:

Turn the key on and off 5 times turns off the auto registration mode.

Gabe Dominique says:

How can I tell if I have 3D or 4d keys on my 2006 GX470. Bought keys from Amazon and tech stream won’t program them. Thanks bro love the video

MADstreetMoto says:

inam ullah says:

John Cangieter says:

Any idea if I would be able to program an aftermarket key fob? The OEM 2 button key fobbfor my Altezza is discontinued. Tempted to try and link a LEXUS key fob to it.

Rally Ranch Motorsport says:

hmmb interesting.
Im in a situation where I only have a valet key programmed to the car, and I have a master key that is cut but not programmed to the car.
and from what I know and have experienced is that you can only program new keys to a lexus using the pedal dance method when using a master key as the host key. the pedal dance method doesnt work with a valet key.
I watched this video but im just not quite familiar or up to scratch with some of the terminology mentioned.

V Don says:

Would this work for a 99 LS400? No master key. Would it be possible to go into Techstream and delete original master key code. Then copy 2ndary key code to master?

Alain Renteria says:

Is it possible to only program 1 master key and one valet key rather than 2 master + valet?

AEON says:

Legit! Thanks bro!

djspock5150 says:

I have a W55 rebuilt from my 2002 is300 if interested. I am moving to a power glide as I drag race a lot.
