- 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 CZcams VIDEOS.

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.
hence they are known as the 'MAIN STEALERS' THERE SHOULD BE A LAW AGAINST THIS PRACTICE
Thank you so much! Worked perfectly 👌 Saved me $1700
Did this work for you???
@@JuanHernandez-ni6bj yep! Really simple if you know PCB work

Gonna go this route hope it works for me my Lexus also got hit in that particular spot and damage the computer
Hi I have Toyota camry the engine not getting a electric crank but not start
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.
Why didn’t you just do the paper clip truck like your other videos?
Worked on my Lexus. In my haste, I forgot to swap the second chip. I hadn’t seen the whole video.
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.
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.
+CK1 I have tried this on my 2013 Yaris and it did not work. I even bought a new Immo thinking it had locked up and still no luck. Do you know if they stopped allowing this in later years?
sir how to kill immobilizer system to 1uz-fe or 3uz-fe vvti ecu...plz tell me..
+CK1 thank you for this information, one day 2001 toyota land cruiser stopped starting, the immo ecu was damaged ,i installed used immo ecu but ECU Communication Registration by jumping pins 3,14 failed because it is not virgin as you said.

hi which of those chips control transmission on gear 4 5 6
Cool vid but don't think this would work for me since I think ECU is burnt. May just be swapping burnt parts.
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!
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?
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.
hi George how can you program man truck which use frr
I cross the battery for my Lexus I S2 50 and he don’t want to start why coda
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
If I buy the same part number for ecu 01 Lexus is300 do I need the ignition and key also or will my old key work?
Hello Mr. I bought a new PCM for Toyota Tundra 2009, I did the process between pin 4 and 13, the car started, minutes later it just turned off and now I have no communication with the PCM, there is a simple way to recover it and do the process again ?
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
good job you did replace EPROM Chip
Hey i bought Lexus is 250 2006 without any keys. How can i program another random key?
Здравствуйте, могу я к Вам обратиться за оплачиваемой помощью с прошивкой новых ключей в иммобилайзер? (Lexus ES330, 2006)
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
this the better way the programing very nice video
Hi George, I have to replace the ECU on a Lexus IS200, will this method apply to my situation?
I got the gs300 different board. Can I do the same to my board?
Depends what year. We can do data swap for you without removing chip on many years call A.M.P. at 301-919-1800
Good info. But you should find another term instead of "clone". You didn't clone it. You used the original ICs.
i have a 1998 gs400 can u help me on location for the chip on my cuz the one your doing this diffrent bord
If I buy a ECU with the keys chip can I switch the chip to my key and start my car?
I have an auto ecu that I’m swapping with a manual ecu, will this work ? Or will I have to try to program it I don’t have the master key for the manual ecu
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
any suggestion for 2010 prius, I lost all my fobs
Can be read and write to other IC ? Or should be change?
Can you suggest same for 1999 RX300 (pls identify contacts in connector to short or ICs to replace with newer ECU
Can I swap ic900 chip between two ecu's that are for different cars but same motor and same year?
Excellent video!!!
Hey George what number ic is the other chip you took out?
What was the other chip you moved?
I always do some in my shop GHANA
Good job, George, молодець.
I got a used 2006 IS250 board today it looks just like this board to the left. same part number at the bottom. It also has the extra chip just like board on left. IC401 area. My used board had a coating of UV paint or coating? Is that from the factory or aftermarket?
you replace all your eeproms from the damage card to the other card
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.
Hey George my Lexus is220d (2006) has p1100 permanent error code How to fix it ? Thanks
I HAVE 1999 RX300 MY ECM UNIT IS DIFFERENT THAN WHATS ON VIDEO.... WHICH ONE I HAVE TO SWAP.. THANK YOU

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.
Hello George .I have a toyota rav4 year 2001 automatic gear and changed the ecu. now does not start, can the same method apply? mean, to change the eeproms between them?
thank you
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?
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.
What happened to your situation?
Hey George, I'm in WA state. I picked up a cheap 2006 RX400H that would not start. Most likely it's something with immobilizer or Hybrid system ECU. Can you please help with some hints/advice? What would be the best way to communicate with you?
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.
Good idea
Very cool
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
Yes you can swap eeprom. Usually its something like s93c66 s93c67 it can be any number.
There is no safer place for a vehicle mounted computer, than under the dash, behind the storage box.
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.
thxs dee lee u save me a bunch of time
Good work bro
Did you get new keys with ecu?
I have a 2000 gs400 how can you tell which one is the eeprom chip

Hallo sir i have a guestion about how to program a computer in hundai elantra
hello mr george, i have nitsubishi galant model 2001 the computer was damages due to flooded. the computer i can save to clean by contct cleaner and dielectric.and heating by heatgun,??
No once computer got wet it is shot. Even if you dry it out it will never work properly.
My ecu don't start why? Please tell me!
Will this also program the vin ?

Good job
That’s a hot air soldering station my man.

Im actually surprised that it has the immobilizer EEPROM on the Engine ECU and not on a smaller separate Immobilizer ECU.
Yeah exactly what I thought. Toyota stopped using the ic900 location for the 93c56 chips after 2005.
Hello Mr. George Melnik, finally when the car start again . there is a high Engine speed (RPM)
so how you get to reduce this RPM !!
What was the deal with your car?
+George Melnik
after replacement the ECU of my car there was hight idling 2500 rpm / min
so the engine accelerates , while the vehicle is in normal position
so how can i reduce idling than 2000 rpm/min to 950 rpm/min
cordially !!
Hello George .I have a toyota rav4 year 2001 automatic gear and changed the ecu. now does not start, can the same method apply? mean, to change the eeproms between them?
thank you
hello ... after having made the transfers of the chips ... can I take in a dealership to encode the key? or will I need a device like that too ?? thank you
Plug and play
Privet George! my 2008 Lexus ES350 lost key and smart key unit has been locked after we tried ten time to program a key.
Please advice how to unlock smart key unit for program new key. Best regards

What scan tool do you have?
Hello How did you resolve this issue? Im curious to know.
Good skills dude!

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?
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!
Model how 2004 or any
How are you supposed to identify an EEprom chip please???

Hello, questions. for a 1999 Lexus es300, which chips do you swap in order to program with ECU.
Thank you.
You dont have to do that you just turn on ignition and leave it on for 30 min with key on and it will program itself
Question: Do I need the key for the ECU, which I purchased in order to program the ECU to my car. (I bought the exact same part number). but the ECU did not come with a key. So, can I just remove the ECU from my car, and replace it with the one I just purchased, turn the ignition and leave it for 30 min.
Thank you for your help.
Ernesto G.
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
Which chips do I remove/replace for a 99 Lexus GS300 ecu. I know about IC900 from SpeedKar99, but what are the other chips do I need to unsolder.
I just swap the IC900 on my 2001 to a 98 gs300 ecu and it works
@@mahtogje ok i will try because I have bad 99 ecu(2 master key), and an ecu from 2001(2 masters keys) and 2000 gs300(2 valet key). I try
Hey George, will this still work on newer vehicles ? I have a 2015 tacoma that I need to replace the ECU for but I heard that most new toyotas have the key's registered in a seperate "Transponder ECU" . Do you have any info on this ?
You can try it does not hurt. I just never had a chance to try it on newer vehicle's
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.
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
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.
Dee Lee it should factory new never been installed unit once installed it will marry the security system
Actually i just tried with used ECM and it was working. Thank you for the suggestion
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 👍
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.
Where is the chip injector in ecu
What do you mean chip injector?
but how to know the original eeprom is also damaged or not.? i mean eeprom data
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.
thank u for reply

hi
i have a 2005 rx300 no spark at all ,showing immobiliser communication fault in diagnostic , can u off the immo from ECU it might be ok? can u do it please
thanks hi tech
👍👍👍👍👍👍
What's wrong with your car
I'm confused. You didn't program shit haha, you just swapped the eeproms. Why not just read the eeprom data from old ecu and write to new ecu, actually programming it..
i don't think u suppose to hit the front of the car everytime. don't drive it's cheaper n will save u 2000 dallors
