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

[@shagytrsc2]

I was gonna give you a thumbs up, but, when I went to hit the button I realized that I had done that ALREADY, thank You

[@SkillCollectors]

If you don't have 4 keys to program, you can exit the auto programming mode by pumping the brake pedal 5 times. Then the security light will start functioning like normal.

[@jmr302]

Binh, thanks so much for making this video. You really, really helped me. I was able to take notes from your video and Dr. Shock's and successfully programmed 4 keys. In my particular case it was on a 2001 Lexus LX470 but it had the same 16-bit eprom (IC900 on the board) and everything worked the same way. The trick was getting the USB driver to work on laptop and making sure the clip was making proper contact with the chip (R/W light on the CH341A).

[@TunerwithKids]

Glad you understood it all. Many people are in over their heads with this stuff.

[@gary6361]

Great video. Online forums just tell you that the ECU is bad and needs replacing! I’ve just purchased an 1999 Lexus GS300. It only came with one aftermarket key and now it’s won’t start. Security light is blinking red. So think I’ll try this to clear all the previous keys coded in.

[@SirCartierxx]

Did it work??

[@adamwestside4077]

How’d it go?

[@jayzah]

Please update us

[@gary6361]

Hi Everyone. Clearing keys didn’t work. But my son found a work around. Here it is: 1. Try and start car once. 2. If it doesn’t start, turn ignition off and back on again. BUT do not try to start. 3. Wait 7 minutes. 4. Ignition off and on again. But this time try and start it. This worked for us. I suspect the 7 minute wait is an anti theft feature. But it times out.

Thanks bruh

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

[@reverseperstalsis]

I tried this and it doesnt work, do you have more detailed instructions?

[@miekolock4060]

That’s for 4d chips not 4c, to turn of the light it needs four keys. With that said it won’t hurt anything with it blinking. But to turn it off you could use any glass 4c chip even if your friend has the same car you can stick it into the ignition and it will save it and not mess his key/car starting his car.

I needed to ask you if a 2004-2005 manual ecu will work with a 2002 IS300. I know their are slight differences in the part numbers but I'm assuming 02-05 manual ecu should all work because the harness is the same.

Hi Binh. Thanks again for a great video. Love the channel. So I got a 2008 is250 a few weeks back, and it only came with one key. I’d like to use this eeprom method to Virginise the relevant ECU so I can add a used key I got my hands on. My question is, are you aware of how to do this same virginise process in an is250? I suspect it may not be the ECU that needs to be worked on, but the “smart box”, which I think is in the boot. Any thoughts?

[@TunerwithKids]

If you have a key. Just order a new key and program it. Order something like this amzn.to/3DmLFqH

[@osmanflores7328]

Your video is much appreciated! Would you know if this same procedure would work for late model toyotas that now come with smart key module (they also call it smart key certification ecu) i opened the box to check out the board and I dont see any eeproms with the part number that is normally used. It is definitely different than the ones prior to 2020. Mine is 22. Any tips would be much appreciated. Thanks.

New have a separate immobilizer box. New ECU just do hard reset to sync ECU with immobilizer.

[@osmanflores7328]

Wow, I didn't expect for you to reply that soon. Thanks! Yes I knew that it has a separate immobilizer, but I thought all the keys information was stored in that smart box. The car was bought at an auction and someone attempted to steal it. the whole system is locked now, and the dealer told me the only way to program new keys was to buy a new smart box which is close to $2k.😢 How can you do a hard reset on this type of smart module? I know they do the pin thing where the short out 4 and 13 but mine does not have any the TS pin. I know it's a lot but any tips would be much appreciated!

Ultimately he got a key to turn on the dash, but couldn't unlock the immobiliser and actually start the car.

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.

[@TunerwithKids]

This is next level stuff. You are hacking the EEPROM to wipe it and telling the ECU it’s brand new and accept the fist three keys it sees as master and 4th as valet on the IS300. Probably same for most Lexus of this era.

Is the only thing that prevents another ECU from working in your vehicle is the immobilizer function and whether it will allow keys to work in the ignition?

I have an all keys lost situation on a USA Lexus RX300 and I'm going to see if an XTool D7 will program a new key without swapping out the ECU. If it doesn't work, I might be following this path.

I would like to know how to program the immobilizer that is in the dash so that the security light will go off and my vehicle will start right now it will not start and there is no one locally in my big city that knows how to program an immobilizer

[@TunerwithKids]

Toyota Lexus would have to seed the ECU with an unlock from corp. usually they don’t like to do this. They’ll just make you buy a new $1,200 ECU plus a new $500 key which they can program easily out the box.

Hey I have a Lexus key but the transponder chip is bad. Can I buy a new transponder chip, use my old key in the new case, and reset my immobilizer to match the new chips code?

[@TunerwithKids]

the transponder needs to be programmed to the car. The chip is highly unlikely to go bad. Its a passive device that doesn't have any real "moving" parts or power.

[@HimMrM]

@@TunerwithKids this seems like a massive oversight on lexus' part, the fact that the immobilizer can literally shut down your car but can still be reset if a thief has the know-how. i guess they didnt anticipate being able to hack it in 25 years

[@NikkiNajera-dy8lp]

pleasae help me it looks like you know yr stuff. my situation is i dont have all the fancy gadget and software for this. i have a 1998 lexus and need to start my car without chip. i have the whole key just not the chip that was located on top of key

[@TunerwithKids]

Need a chip that was already programmed to add any new keys or need to do what I showed and reset the ECU.

[@VegasAlex702]

Is there a way to test the assembled reader before using on an ECU and potentially damaging it? I just assembled the modified reader and used a multimeter to verify the connections, but I'm nervous to connect it to an ecu for fear that it could damage the ecu.

[@TunerwithKids]

Only way is to plug it and read the chip. It won’t damage anything.

[@VegasAlex702]

@@TunerwithKids would you agree that it's safer to just virginize the new ecu so that you can just pair your existing keys to it, versus having to remove and read the old ecu? I was thinking that's the smartest approach to avoid potentially damaging my working/paired ecu.

[@TunerwithKids]

If you know how to go thru the pairing process. Just virginize it and program keys.

[@VegasAlex702]

@@TunerwithKids thanks for this video! I was able to build the adapter and successfully read and virginize a spare ecu that I'll be having changed to a manual trans one soon. I'm going to test it tomorrow with my car to make sure I can enter programming mode and pair my existing keys.

[@VegasAlex702]

@@TunerwithKids I tested out the virginized ecu and it started my car np. The red security light stayed on waiting for other keys, but I'll address that later.

[@junaidiqbal8912]

Can you make a video on how to get pincode from immobilizer dump

[@TunerwithKids]

Pin code? You mean the Techstream ECU flash unlock code?

[@ogexoreaper2052]

is it flux on the ecu just use iso alcohol

Can I reset / reprogram a used Lexus ECU with an original key Without having a car on site? If so, how hard is it? I have Autel Im508.

[@TunerwithKids]

Not with any tool. If you do this, you can clone another ECU immobilizer. Or reset it to allow any key to be added.

[@mohammedawal3640]

Thanks

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.

[@TunerwithKids]

Should work, the key immobilizer is a “4c” chip used by many cars and brands. The remote portion is different computer and programs differently. Most all Toyota use the same frequency and chips.

My car is 2003 Chrysler Concorde, how do I find out the EEPROM chips? the number?

[@TunerwithKids]

Idk.

[@MaffewP]

Hi Binh! Great video, I am in the process of doing this but when i am in asprogrammer I keep getting IC not responding. I am a little stumped at getting this to work i made sure i had continuity on all the wires. Any help would be greatly appreciated.

[@screwloose2000]

Hi, did you find a solution to this. Its the same thing for me. I have done the 5v mod and am trying to read a 95xxx series.

[@MaffewP]

@@screwloose2000 did not get it to work :( instead I got tech stream and that was much easier

[@anthonyfilardo9972]

I want to attempt this with my Raspberry Pi and I already have the SOIC8 clip. Do most 8 pin chips use the same format?

[@TunerwithKids]

It’s standard chip. Need a 5V to write, 3.3V won’t activate the write pin.

[@anthonyfilardo9972]

@@TunerwithKids Thank you! Do you know if the SERIAL HOLD (SOIC8 pin 7) also pin requires 5V?

[@TunerwithKids]

Idk. It should be in the chip data sheet.

[@4NDR01D5]

You can bump it to 5vdc with a pull up resistor or using a different arduino or maybe using a ftdi writer

[@bubbles80882]

After doing this (and keeping the valet key lockout) it only allowed me to program one key... Why is this? 2002 RX300

[@TunerwithKids]

Idk, if you reset it as new, the ECU wants to program 4 keys, two master, a card lockout and the valet.

Ciao Honda moto sh300 EEPROM 93a66 ho perso le chiavi..posso programmare una nuova vergine oppure annullare immo ?

[@Sanjeev_Narrie]

hey i have a 01 IS like you, i have a no spark no fuel problem. i suspect my ecu is bad. i got another ecu from the junkyard without keys. would i be able to program my original keys to the junkyard ecu using this method? (only have 1key in total)

[@TunerwithKids]

Yea. Copy the EEPROM from old to new.

[@Sanjeev_Narrie]

@@TunerwithKids thank you i appreciate it will buy the equipment and give it a go!

[@Sanjeev_Narrie]

@@TunerwithKids Hey im having problems making soldering the board. if i use an air solder and swap the eeprom would that work?

[@TunerwithKids]

@@Sanjeev_Narrie that’s more potential for damage. If you can’t modify the programming board, I’m not sure if you should attempt to remove eeprom with air iron. That’s a dangerous tool in the wrong hands.

[@Sanjeev_Narrie]

@@TunerwithKids i can solder really its just i not sure if i doing it right as my pins i ordered are short and it doesnt look like how yours are in the cluster video. thats what i think im confusing myself about.

[@mangoop2397]

Hey Binh, I have a manual ECU with no keys and it's the last part of my swap. I wanted to try this method to get keys programmed but I don't think I have the technical skills to modify the EEPROM Programmer to read the cars IC900. Is there any way to buy an EEPROM Programmer modded already, or is there an alternative method to reseeding the Immobilizer possibly with techstream you are aware of?

[@TunerwithKids]

theres guys on the IS300 forums that can do this as service/business (Quantum auto?). It will be cheaper than reseeding via dealer.

[@crism9145]

Can the program run on Mac iOS?

[@TunerwithKids]

I doubt it. But any Hex editor should be able to view the code. The problem is finding one that has drivers for the USB hardware.

[@crism9145]

@@TunerwithKids I have a USB adapter 😊

Will this work with Mitsubishi?
