I know you probably won’t read this, but despite the pandemic, I was able to commit in doing this and saving my car from street parking! You’ve saved lives with these videos. You’re a hero, thank you for the content. Amazing work, I can’t thank you enough.
can you share what hardwareyou used to connect to the chip? I'm hoping to use a USB connector like the C341a, and since it uses different software I can't be sure why it's not connecting
@@mrkazman sorry mate, I used the serial port and I don’t exactly know if it’s possible for the USB port, I used PonyProg which is the video above’s program, serial port and whatnot.
@@mrkazman requires an serial port capable of 12v communication levels. this is what the zener diodes and resistor do (clamp voltage down tp 5v TTL) If you use a USB to serial cable, you have to adjust the circuit to the new (lower) voltages and is dependent on the USB serial chip. Like this guy, I also just use an old computer with a proper serial port but in my case, it happens to be an old laptop. Since then I have simply built a custom serial USB adapter.
Hey man, just wanted to let you know that thanks to your hard work and documentation, I just successfully did this on my 1998 LS400. I used an EZP2019 programmer and it's own software. I ended up having to remove the chip and resolder, and even then I couldn't get a proper read(locations of all the code were correct, but a bunch of repeating numbers that weren't logical. Even the valet lockout code was completely different), and it wouldn't write(I probably torched it taking it off). I bought a replacement chip for 30 cents and ended up just zero'ing and putting in the lockout code exactly like yours and it wrote/verified fine, so I tried it out and sure enough, it worked! For 16 months I had a paperweight in the garage that I was repeatedly told by dealerships, shops and locksmiths continent wide(actually called 50+ locksmiths across North America) that it was impossible to do. Finally after some further research I came across you and now I've got my baby back. Thank you so friggin much. Seriously, you have my utmost gratitude.
I'm a mechanic and that's exactly the car that I'm working on right now, 1998 Lexus LS400 I swapped the ECU used from a junk yard, now I'm trying to figure out how I can program the key to start the car, one local key smith don't want to do it, the 3rd I'm waiting an answer, little bit more research from myside and I will try to do this myself.
I saw your comment and just had to stop by and say that, I will be doing this to my 2000 LS400 very soon and reading your comment gave me a boost of confidence.
@@huynervo It was scary as fuck for the months of planning leading up to it, but as long as you don't melt or fry the ECU itself, I'm sure everything will work out. Also, the vehicle still works fine to this day, so there's nothing to worry about with longevity.
Dude, great video!! I'm just discovering your channel, just watched your other video on AC compressors. Really digging your channel, instant subscribe 👍
Well that's all it takes. Looks like you need to just start a business doing this because I'm sure that almost nobody has a clue even after watching your video so maybe you could help some people out? Least I know I'm still lost. Lol
You’re a solid teacher! Though it gets above my head eventually. Question.. Do you really have to reprogram a new manu replaced virgin ecu ? I’m in a all keys lost 04 Toyota Sequoia in a rural area with the only locksmith in the region having failed to be able to reprogram orig ecu after multiple trips out trying. Dealer (which is over hr away) says Control Module, Amplifier, and new keys all need replaced for this model Seq .. for a fortune. 1 Can I just plug in new toy manu ecu and new keys and program keys and go?? 2 Do I really need to change out amplifier? Thanks
This video is well done but it includes a major error that need to be corrected in order not to mislead readers into a frustrating experience. The included electrical schematic for a homemade EEPROM reader do not work. The software (Ponyprog) does not recognize this homemade circuit as a serial communication device. The for immobilizer hacking shown in this video will work only with the use of professionally produced EEPROM reader and there are lots of those on the market.
Great job bro! where did you go to school at? i wish i stayed in there a little longer when went. i was young and probably bbad timing in my life. any way great job bro keep up great work
I swear it’s easier to just swap the eeprom chips from the old ecu to the new one. I’ve done it before on voltswagons. You just need micro solder tools. Just the mini heat gun. Done in 20 min
Dope video nice to see all the values in their places for sure. But are familiar with how you would edit the chip to be a NONE IMMO or (Ready to start, as they call it in some ecu programers)
James Svetlovics I did this for mine thank god, you can look me up at spyderchat davgnzls, you can start the car with just one key but the security light will keep flashing until you find 3 keys
For anyone wondering this is a very specific method that is only applicable to this environment. This is not how ever system works nor will most of this information generally help you in anyway towards other applications. Great vid for this specific application though.
Toyota used a nearly identical system in most of their vehicles for just shy of a decade. This worked in my 1999 and 2000 4runners and to my understanding, would work in many other cars. But yes, this is not applicable to significantly newer toyotas, or something from another manufacturer with it's own unique software. However, the basic concept of programming an eeprom memory chip can be applied to dozens of car models and manufacturers for all kinds of different functions.
Hello,i would like to ask in 3:59 of video about the numbers of keys.FF means no keys,FE=1 key,and value FD is both for 2 and for 3 keys and this confuse me somehow.Otherwise the counting of keys number looks like one's complementary.
"Immobilizer hacking" no shit. No click bait here! You're brilliant. Not sure I can recreate the process shown here, but boy was this interesting. "Thats all it takes to hack into your immobilizer in case yoh lost all your keys." Yeah, just have a 'state of the art' computer with an external board 😂👍👍🙌
If I only had a valet "DOT" key and bought and cut a new master "G" key, will the computer automatically read each as a valet and master respectively from the chips in the keys themselves?
Great video. Although my technical skills are not good enough to even attempt it. I just picked up a 99 Avalon xls, with the Toyota theft deterrent system in it. Would you do this on my car for a fee?
My 06 caravan , the wires in the plastic ring surrounding the keyhole, those wires were pulled from the immobilizer box... id like to solder a wire into the box and run the wire arounnd the keyhole. Theres 2 metal "posts" off the chip. Id like to confirm thats where the wire ends get hooked.
This is really awsome. How can I add another transponder who can receive a remote signal from a remote key to turn on the engine. Like a transponder who has a relay in serices and that relay activates with a remote signal say from 20 ft away from the car. Basically turn on the car remotely.
Very cool video. I need help. I wanted to try that with Hyundai Santafe 2005. But guess what? Couldn't locate the eeprom on the ecu. There are no 8pin chips on the foreside of the ecu. The underside has eight 8-pin chips. Non of which I'm convinced is the eeprom. I am about to check for transponder ecu for the eeprom. My worry is this; is the eeprom in the transponder ecu? If so, can I use the same procedure to reprogram the eeprom? Is any of those small 8-pin chips on the rear side of the ecu the eeprom? Does this method works with Hyundia? If not, what can I do.
Some questions. How do know if you have a master key before doing this? Does the ecu automatically make a key master then after the second one the third becomes a valet? What if the only key I have is a valet? Will this work? And lastly, do you need 3 keys? Or can it be done with just one key? Thanks
Hi, how exactly would this work on newer 2007 Toyota Matrix? This car has both ECU and Transponder ECU. Where would I try to get EEPROM data from? You say on newer vehicles the procedure is similar but you need a handshaking procedure between transponder ECu and Engine ECU, how is this accomplished?
Thanks so much for responding!! Would I still need to pull EEPROM dump from ECU? Or just short out pins, wait 30min and then program new keys (All previous keys were lost)
My car is Daihatsu Sirion 2007. Can you explain the procedure for a separate transponder module and ECU? Should the pins on OBD II be shorted for 30 minutes or 30 seconds and should they be shorted during the key coding procedure?
There should be eeprom chip in transponded module, might work as in video. But if you are swapping ecu for used one it might also been paired with immo, then there should be chip in ecu also for pairing. But this is my theory.
I bought 3 new keys but thanks to a newbie at Ace Hardware putting a hole through one of them, I now only have two new keys which include the Lock/Unlock, Panic buttons. Will it allow me to program only 2 masters?
Ok. So i have original ecu, an original key fob but new ignition switch and new keys with no programming. I pulled out the ecu (an Delphi MT38) thinking i can just take the entire IMMO chip off and have the truck start the old fashioned way. But don't know which chip to pull. There's only 2 ..8 pin chips on the board. And one in the key fob. Numbers don't match. I also have the old ignition switch assembly with transponder ring. So could I just put the old transponder ring on the new ignition switch and will it start up like that with the new keys. I'm thinking it will work but one roadblock may be the signal from the new keys and their chip maybe blocking comms.
this is great and you are a good instructor, I am impressed, is there any thing different with the 02 Altima ecm and what about the bcm on this model , thank you plz guide me with this car .thanks again
Could you just run a jumper wire from somewhere on the EPROM to the code wire returning to the ecu, feeding itself its own code bypassing the amplifier all together?
Great video. 1. Something is not clear to me though. The value 0xFC at offset 0x4C means there are 252 keys stored in the eeprom. The eeprom's capacity is 256 bytes. 2. Can you program just a single key?
@@fernandohood5542 What worked for me to end programming with a single key was: After the key was inserted, removed, then inserted again for 5 seconds, I had to push the brake pedal 5 times. This was on a 2001 Highlander. I was able to use an EZP2023 programmer with a chip clip the last time I programmed it (at one point I removed the chip from the board due to connection issues and wanting to experiment, but the final flash was done with the chip in circuit via clip).
Do you do this for others at a charge of course? I've watched your video 5 times and yet, I cannot find a way to connect my computer with no serial port to the car. I"d be afraid to blow up the PC. I have a 2003 Avalon with all keys lost and already bought the new chip key from Toyota dealer. I'm looking at who to send the ECM to program the key, or do a "Immobilizer defeat"
@@speedkar99 Thanks for the reply! I actually managed to program it using a CH341A although it doesn't officially support it. For the rest your steps helped a lot. You rock!
Sorry mate, these chips use microwire which is unfortunately different to the common SPI protocol. I managed to get a read off my 93c66 using an arduino and a microwire EEPROM library, but it's dodgy as heck and I'm not confident enough to delete it without deleting the valet lockout adresses. @speedkar100 are you saying that if I wipe my chip, I'll only be able to program ONE valet key? What's the difference between a valet key and a master key in terms of normal engine driving?
Hello, I have a 2005 Camry Xle and there isnt a IC900 EEPROM chip. I am not sure how to tell which EEPROM has a reference to the key transponders. How did you narrow it down to IC900? I purchased a car that only had a valley key and would like to have more than one key, but I cannot program any keys. Could I send you a picture of the ECU? Thank you so much for your help!!!
Hello, go to a specialist / locksmith and copy the transmittercode from the working key to a empty programmable new key . There are tools that can do this for low cost
Hey there I have a mitsubishi lancer se 2012 I want to change my immobilizer to a different one and program a new keyfob can I do it with this method or am I screwed.
Hello, my father lost his only chip key. The car is a 2003 Honda Accord. I got a new cut key for the car but it has the green key flash. I just want to know if there is a self programmed system you can do by your self without going to the dealership. Note: I have a regular transponder key not a remote key. If not, could you tell me someone who might help me. Again thank you.
Hi, thanks for the video, very helpful. Can anyone confirm if the keys on all eeprom's repeat 3 times? I seem to have code only repeating twice. Thanks.
Would it be possible to talk to you about coding an ECU & immobilizer unit for a new set of keys for my vehicle & pay you to do it? I didn't see any way to contact you privately.
Hallo. For EU cars - so the IC900 on the transponder ECU must be programmed - correct? But the Engine ECU still are with the old key-codes - correct? My LandCruiser Prado is blocked, bought a used set of keys, lock, transponder and Transponder ECU - but the Engine ECU does not accept the code from the Transponder ECU. So, resetting the Transponder ECU like shown, will lead to Engine ECU accept Transponder ECU?? Thank you, you surely my last help. Car is in between 10weeks at the repair shop.

Thanks man! This is awesome! Do you know if it's possible to flash using a CH341A ?
Not sure what the capabilities of that are
@@speedkar99 Thanks for the reply! I actually managed to program it using a CH341A although it doesn't officially support it. For the rest your steps helped a lot. You rock!
How did you manage to write 93CXX with CH341? There are only 2 options 24XXX and 25XXX. In what slot do you put it?
can you help me out on how u used ch341a to program ? what O.S did u use windows 7 or Linux ? what slection on the program did u use?
is the memory chip a SPI flash chip? can we rewrite it with CH340 programmer?
Sorry mate, these chips use microwire which is unfortunately different to the common SPI protocol.
I managed to get a read off my 93c66 using an arduino and a microwire EEPROM library, but it's dodgy as heck and I'm not confident enough to delete it without deleting the valet lockout adresses.
@speedkar100 are you saying that if I wipe my chip, I'll only be able to program ONE valet key? What's the difference between a valet key and a master key in terms of normal engine driving?
to be clear, I won't be able to program master keys then?
Will this work on 2014 tacoma 4.0L?
Hello, I have a 2005 Camry Xle and there isnt a IC900 EEPROM chip. I am not sure how to tell which EEPROM has a reference to the key transponders. How did you narrow it down to IC900? I purchased a car that only had a valley key and would like to have more than one key, but I cannot program any keys. Could I send you a picture of the ECU? Thank you so much for your help!!!
On the 05 the chip isn't in the ecu, there's a small box underneath the dash by the glove box latch that has the chip inside
Hello, go to a specialist / locksmith and copy the transmittercode from the working key to a empty programmable new key . There are tools that can do this for low cost
Can you link to a USB programmer that I can use thats compatible with this chip? I don’t want to wire my own circuit.
Hey there I have a mitsubishi lancer se 2012 I want to change my immobilizer to a different one and program a new keyfob can I do it with this method or am I screwed.
Hello, my father lost his only chip key. The car is a 2003 Honda Accord. I got a new cut key for the car but it has the green key flash. I just want to know if there is a self programmed system you can do by your self without going to the dealership. Note: I have a regular transponder key not a remote key. If not, could you tell me someone who might help me. Again thank you.
No you have to fork over and get to a locksmith
@@speedkar1005 thank you
It's probably a bit to late to get a reply, but using this method could you just dump the original ECU's eeprom and write it to the replacement ECU?
Yes, you could.
Yes
Will this work on a 2000 Lexus GS300?
Yes
Have any info how the smart key version would differ from this rfid version? thanks
IC900 is it same with the IC902? seems theres no ic900 on a 1hdfte 2006 ECU
Hey my ECU has a label IC900 but there is no chip in that spot
Then you don't have an immobilzer
Hi, when selecting from device, it shows me microwave 16 eeprom and 8, both have 9356. Which one should I use for a mitsubishi outlander 2007? Thanks.
will it work if you replace the coil ring and key from another car
At 03:33 .. that looks more like 2.5 BILLION combinations... (you say million)
very intersting video tnx bro
I did this for a 99 4runner, I followed everything to the exact description and it does not work at all.
Can i remove the chip off the ecu ? Will it work ?
Hi, thanks for the video, very helpful.
Can anyone confirm if the keys on all eeprom's repeat 3 times?
I seem to have code only repeating twice.
Thanks.
will this work with only one key
Thanks for this great video! How about with Honda ECUs?
Those are more complex. You need HDS to handshake the new ecu to the transponder chip.
@@speedkar1005 - how can someone learn all this??
Hi I need help with Honda prelude 2001
Would it be possible to talk to you about coding an ECU & immobilizer unit for a new set of keys for my vehicle & pay you to do it? I didn't see any way to contact you privately.
Hallo. For EU cars - so the IC900 on the transponder ECU must be programmed - correct? But the Engine ECU still are with the old key-codes - correct? My LandCruiser Prado is blocked, bought a used set of keys, lock, transponder and Transponder ECU - but the Engine ECU does not accept the code from the Transponder ECU.
So, resetting the Transponder ECU like shown, will lead to Engine ECU accept Transponder ECU?? Thank you, you surely my last help. Car is in between 10weeks at the repair shop.
Can I just go to pick a part and get a matching key and ECU would that start the car???????
Is there a way I can wipe the codes so that I don’t need the key reader or anything? So the ecu enables without a key? Using a in a track car.
How did you learn how to do this?
Lots of trial and error and research online
very informative ideas how to repair and program immobiliser i want to learn about that
Life hacks at a glance
Yeah
what about the VIN # from the replacement ecu. it won't match your own. so what about that issue?
