HOW TO PROGRAM LEXUS TOYOTA ECU IMMOBILIZER KEY AFTER ECU SWAP

This video will show you how to program most Lexus, Toyota ECU key immobilizer after ECU swap it's common to have ECU damage after accident on most Lexus and Toyota vehicles.. This video will show you a 2013 Lexus is250 ECU being cloned.

THIS IS THE BEST AND VERY AFFORDABLE SCAN TOOL. I ONLY RECOMMEND THIS ONE. I USE IT IN ALL OF MY YOUTUBE VIDEOS.

You do realize that was completely unnecessary, right? All Toyota/Lexus with the separate Immobilizer ECU (like your IS) have the ability for the Engine ECU and Immo ECU to be resynced without any special equipment. The process literally involves jumping 2 pins in the DLC (4 & 13), turning on ignition without starting engine and waiting 30 minutes, then turn key off, remove jumper and verify vehicle starts. Toyota calls this "ECU Communication Registration." This works if you replace the engine ECU and still have one or more original keys (to the vehicle) .. it does not matter if the replacement Engine ECU is new or used. This process can also be used if you are replacing the Immo ECU with a BRAND NEW one (so called "virgin" one), but will NOT work if you are replacing the Immo ECU with a used Immo ECU because I doesn't reset the keys to the Immo ECU, it resets the communication between the Immo ECU and Engine ECU.

Seems that a lot of dealers are buying ECU/ECMs, etc. from the local ECU/ECM shops. You can get ECU/ECMs repaired or replaced fairly cheap now days. The dealers are marking up replacement units and programming - as expected.

Gonna go this route hope it works for me my Lexus also got hit in that particular spot and damage the computer

[FoIlowTheLeader]

Hi I have Toyota camry the engine not getting a electric crank but not start

Hey George. Thanks for an awesome video. Hoping you can help with 2 questions i have. 1) You swapped over two eeproms in this video. Exactly what information did those eeproms contain that needed to be swapped from one to the other? 2) I want to try and virginise the relevant ECU in my is250 as ive lost all the keys. Do you know if this is done using the SmartBox, or the ECU? Im hoping to be able to read the relevant ECU eeprom, zero it out and reload it back in. Thanks!

I know it's been a while since video was made, but what vehicle was this out of ?

[AutoEliteTV-]

Hello sir. Currently, I am using Powerbox for ECUFlasher and I'm trying to connect it to Toyota Camry 2007 Hybrid ECU via Rainbow Wires. Do you have the connection video of it? If you have, I would like to buy it from you.

hi which of those chips control transmission on gear 4 5 6

[RichardsWorld]

Good info. But you should find another term instead of "clone".  You didn't clone it. You used the original ICs.

[MugangaJohn-dw]

What do the chips that you changed do in the ECU

[Paul-yqls]

My computer got flooded. Anyway when I take my ecu out, my door locks and windows etc still work, even with the touch locking? . I can even turn the engine over however it won't start. I just bought a second hand one off eby, and I'm pretty excited to hear it run for the first time since I've ownd it What were those 2 chips for?

[PokemonClassicMaster]

Worked on my Lexus. In my haste, I forgot to swap the second chip. I hadn’t seen the whole video.

[jzboost]

Goodnight. I have a question. how do I remove the immobilizer from my gs300 ecu.. I did an engine swap but the new computer has an immobilizer also and my current computer cannot work with the new engine. thank you.

Hey George ! There is a p1100 pdtc on my Lexus is220d 2006 I have cleaned and reinstalled maf sensor
What do you recommend me to do ? Error is still there I believe my car consumption is higher and I take time to accelerate

[macmike]

Hey George, when doing this did you verify that the correct mileage was transferred over?
Like when you check the mileage with a high end scanner, not on the cluster which has its own separate storage.

[cocktaliana]

hey not for nothing but I just realize you missing an eeprom in one of the pcms the new one you putting on has an extra eeprom on the left side next to that microprocessor its a 93c66 put attention and you will see that frigging prom is extra

[anthonyplantt]

Hey George what number ic is the other chip you took out?

[waldoguzman]

I need help, I want to know what are the ecu cables to start the disassembled motor? I know one is red with black which is the other ??? Thank you
