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 KZbin VIDEOS.

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.

[@autokeysremotes174]

Good job, George, молодець.

[@tonyalison3068]

[@daprincehwc]

hi George, good video. please before you do the swap, do you have problem with the steering not being able to turn, like having the power steering light on. .... my 2006 Is250 has a steering lock due to driver front side accident and the steering locked toward left and won't even turn a bit. lexus want me ro replace the ECU and Rack & pinion.

So I had a question 2013 Tacoma if u flash that chip if I flash that chip will it be able to be input into program mode to program new keys without the master as long as I have one cut from the VIN or would that be in the immobilizer

[@mac1mike]

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.

Can I swap ic900 chip between two ecu's that are for different cars but same motor and same year?

[@davef2415]

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!

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.

What was the other chip you moved?

[@ionicbreeze]

wow you make it look so easy! I have a 2000 toyota tacoma that for some reason cannot communicate with the scanner. it worked for 2 days after I bought it and then boom, no communication error. I was told it was the ecu from a few shops. I purchased a refurbished ecu for $400 but it does not include reprogramming my original VIN # onto the refurbished ecu. Can I just swap eeproms like you showed so that the VIN #'s will match? If so how would I go about finding which chip to swap? Thanks. Subbed

[@melniksmotors]

Yes you can swap eeprom. Usually its something like s93c66 s93c67 it can be any number.

[@chairmanmaozedong]

Hi George, nice video. What was the second chip you transferred? Dealer told me my 2000 Lexus lx470 ecu was bad. bought a salvage and had electrician swap eeprom but still get the blinking security light and no start. Do I need to move another chip?

[@deelee3462]

Hello Can you say the inscription of the chip you moved initially. Also do you have correct milage and vin number when you swaped first EEPROM. Also he swaped 2 eeproms. Im trying to figure out what eeprom you switched and what it does and if you swap out the second eeprom what it will do. I also wonder what will happen if one of the chips was an immobilizer and if that was disconnected. Will that shut off the immobilizer and allow car to run and with security flaw? Thank You for this learning opportunity.

Is it necessary to do this "cloneing" on this year vehicle? Cant you just pop in the alternate ECU and short pin 4 and 13 and wait 30 minutes like your other video. and then use techstream to write the vin back into ecu? or is there any other information that this process will cover that the steps above wont? I think the mileage is in the cluster and the key information is in the smart key module.

Do you know how to make the car enter programming mode if you virginize the ECU's EEPROM?

How do you virginize a ECU EEPROM? Also About your immobilizer /ecu question im curious about this too. What does the immibilizer ECU ( seperate from ecu/ecm) if the initial data isnt on it. Also im not sure if he says what car it was from. So this could of been a standard transponder ecm instead of a smart key type. Did you obtain any information about this?

[@AN-kg4ei]

I think the IMMO, BCM, ABS, etc. modules would need to be reflashed to the new VIN? In my experience all modules need to have the same VIN coding or there will be faults....? Unless VIN info comes off another EPROM? Thanks for sharing!

[@melniksmotors]

You can try it does not hurt. I just never had a chance to try it on newer vehicle's

[@deelee3462]

Did you ever find the answer to this? Im very curious. I think newer cars have atleast 3 computers ECU/ECM, Immobilizer, and Smart Key. This is in addition to one for power and electronics inside.

[@dashtyATG]

Hello George I've seen 1 of your other video regarding a Toyota ECU cloning while you just read from the old chip and write it to the new used ecu chip. So my question is did you cleared old data from the old ECU chip or it clear it automatically I mean don't you have to verginz the old 1 before you write new date to it? Hope you answer and understand my long question.

[@xmdude626]

you need to actually do a virgin dump on the new ECUs eeprom to be able to program your key. Since that ECU you bought, has the codes for the keys for the other car

but how to know the original eeprom is also damaged or not.? i mean eeprom data

[@melniksmotors]

Eeprom data hardly ever gets damaged. Even if its a flood car you can still copy eeprom data. If eeprom chip not cracked or busted it should have all data, unless you apply direct voltage to the wrong pins.

[@abdullbasitosman5070]

thank u for reply

[@ck1740]

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.

[@melniksmotors]

Yes that will also work but on a car that has a smart key start system it will not work as it will not let you turn on ignition also it will not write vin number or rewrite vin number in a user or new ecu. Then later when you hook up scan tool it will not read no vin or if its a used exu it will be reading old previous vehicles vin number.

What's wrong with your car

[@Airman..]

Actually the new ECM aka computer wont need any programming cause it has a program in it intended to be learned automatically once installed on the car good job though

[@deelee3462]

Is this from a factory new ECU or just one that is new to the vehicle meaning it could of been a previously used unit.

[@Airman..]

Dee Lee it should factory new never been installed unit once installed it will marry the security system

[@deelee3462]

Actually i just tried with used ECM and it was working. Thank you for the suggestion

[@Airman..]

Dee Lee yes this 👆 could be done with a previously programed EEPROM there is another way though which is rewriting the EEROPM data with a programmer software like Carprog or Vprog (look it up) without a need for the old maybe toasted ECM , some websites offer the Virgin EEPROM file for sale too. Good luck 👍

[@deelee3462]

I was playing around with trying to solder wires onto an epprom. My goodness its difficult. But i figured if you can marry a used ecu to the car. There is little benefit to writing eprom data. The Vin can be written to the ECU with techstream and immobilizer will be set after process. So with the old EEprom what other important data will there be? I think the odometer is stored somewhere else. Thank you i will look into carprog and vprog for other vehicles.
