A very good job explaining the basics of a immobilizer system. Very good video work also. Thank you for all your hard work making this video.
Thanks my friend. I’m glad you enjoyed it
Dude that’s basically what I did but I tapped whole key to the bottom well zip ties it inside the whole on top n used my house key to start my car it is dangerous cuz the theft like u said but yeah I’m happy cuz I figured it out like two three months ago alone but I got a brand new parts n I’m safe but my car went ever where still work etc thank god but it made me happy cuz u did basically same thing but all nice n neat mine got fuxkeed up cuz my key got stuck broke in half drilled it out duxkeed it up smh then to where I just had the cylinder lock n drive it no problem until I got payed for new one thank u good night ❤🎉 I’ll rate u 100

Excellent
Thanks
very nice video thank you
Glad you liked it
Nice job.
Thanks!
the video is very interesting. Thank you. I would like to ask if it is possible to use an oscilloscope to check the communication signal between the transponder chip and the antenna coil? or check the antenna signal information via immobilizer control instructions
We can use the oscilloscope to check the waveform between transponder antenna and immobiliser control unit. I will try to make a video from that very soon.
Thank you. I hope for a reason
Nice job
Thanks
Good video brother. Im very NEW to immobolizer systems brother and just wondering if the transpoder chip has the Key Code or is it separate??? If so, then what numbers does the transponders chip hold compared to the Pin number. Thank you
Hi my friend. When you register a key, transponder chip identification number will be saved inside the immobilizer control module (and in many cases ECM too), so the next time that you want to start the engine, immobilizer checks to see if the transponder number is same as what is already saved initially. If they are similar, engine will start.
@@AutomotiveDiagnosis i wonder if you could record the transponder signal with sdr or oscilloscope then program an arduino to replay it?
I love your videos
👍👍👍
Would it be possible to swap on a car the antenna coil and put another from the same model of car with a matching transponder and original key cut? Ive been told to replace bcm because it triggered the alarm. I just need to deactivate alarm y order to program new key
Thanks mate, only one question, so what should we do with that chip if we upgrade the ignition switch to push button start?
Thanks 🙏
Normally when you upgrade the ignition switch to a push button start, you will still have your immo under the dash and you need to tape the chip around the antenna coil to inactive the immo. I don’t really recommend this kind of upgrade as it is not really secure system for the car.
great video
Glad you enjoyed it
I really enjoyed this video and learned a lot. Well done!
Thanks a lot my friend 👍👍👍
very good sir
👍👍👍
❤❤❤❤❤ good luck
Thanks my friend
Thank you.its for a mazada drifter 2.5 I.cut a key with a remote
We had to replace a the steering lock on a 08 plate seat leon. I figured out that the antenna is common and not coded, just like you said it just relays the information from the transponder(chip) to the module then ECU to check if they match up? is that correct? although it may become faulty there is NO CODE relevant to the antenna? thanks for your explanation.
Hi there, thanks for sharing your experience. Yes, that’s correct. But sometimes transponder antenna and immo control unit are integrated into one unit which in that case we might need to reprogram the keys.
@@AutomotiveDiagnosis Ah thanks i get that.
@@alanpatterson2759 👍👍
This is probably a stupid question, but if it disables power to the fuel pump can you not just take the fuel pump relay out and jump it with a wire manually, assuming it has a relay for that?
Hi there, it’s still not going to work as injectors won’t work too.
❤❤❤good
👍👍👍
Where you put the black leat in the resistant test?
Where do you get the pass word and keys?
Perfect tutorials, waiting for more videos 👍👍
More to come!
Which types of suspension and differential are used in Mercedes
Can I do the blocking using a relay to cut and connect the immobilizer antenna wire?
Hi there, you can put the relay on may different circuits, fuel system is the most common one, but of course you can go for the immo as well.
Does key code get sent to immobilizer module by radio wave(wirelessly)?
Yes, through Radio Frequency, normally 125 kHz
Where are u located sir i have a problem with my isuzu 250 kb
❤❤❤
👍👍
So would it work if you switch the key and the mobilizer from a different car to yours will it start the car
Hi there, for Hyundai and Kia vehicles you have to swap ECM, Immo control unit and the Key. But they all must be from a very same model and sometimes programming is needed too.
How about replacing all three parts with that start another car
how did you get the ems neutral code thanks
I got the code from the manufacturer’s technical website, but there are many other ways to get code.
Hello sir .
How I get the 4 digest code?
How I get the 6 digest code?
Thank you
Hi my friend. 4 digit PIN code is used for the emergency starting and you can enter it by scan tool. So you need to save the 4 digit PIN code first, then you can inactive the immo for 30 seconds for starting the engine in case of immobilizer failure. For the 6 digit code, you can get it from the dealerships or some vin to pin software.
Please remive the plastic cover on the multimeter😊
Sure my friend 😅
Is it true that every time you use that reprogramming machine ,
you get charged by different vendors to allow you the use of programming and the reprogramming of the parts.
Hi there, not for every programming. Most of them can be done with scan tool without any charge. But for some cars you need to have access to a technical website to get the programming software and that’s what you need to pay.
I dropped my car key and it fell apart. I gathered the parts without finding the transponder, now I got a major problem. Can I take my key to a locksmith without my car and have him put a new matching transponder in without my car present?
Hi there, if you have the second registered key, they might have a tool to copy the registered key and make a new one (not everyone knows how to do that), otherwise you have to take your car to a locksmith as they must program the new transponder to the immobilized and engine ECM.
Thank you for video, my elantra 2008 sometimes key light is off and engine doesn't run, how can bypass it please.
Hi my friend. You mean engine does not crank at all? Or you have crank but no start?
Renault Clio 1998 I lost the key and I'm stuck on the street, I can't go anywhere, and how can I start it with the help of a wire?
❤🙏🙏
👍
what type of vehicle is this on?
That was a Nissan, but immobiliser is pretty much similar on all cars.
That's what we want, no inmobilizer BS.
I stupidly broke my imobilizer trying to get a stuck key out.
No idea where to start but I think this is something.
So you broke the immobilizer ring around the ignition switch cylinder?
@@AutomotiveDiagnosis Yes. I'm thinking about trying to just put it back with some wire and try. I only see the copper in the ring and not coming out of the other piece. Any advice 😬?
@@higherlunacy If the internal coil is still ok it might work.
You didn't mention anything about the connection between the fuel pump and the immobiliser unit. Is it simply relay control or something not that straight forward.
Fuel pump is controlled through the ECM, so, there is no direct connection between the fuel pump and immo unit. Basically immo unit communicates with ECM and the rest is on ECM.
My alarm dont want to go off it keeps on making a funny noise ,my window cant go up if i press the button for the window to roll up then the alarms goes on making the normal alarm noise
By any chance, do you know if there is any aftermarket antitheft system is installed on your car or not?
@@AutomotiveDiagnosisyes there is...
Sir where we get 4-6 digit passward
Hi my friend. 4 digit PIN code is used for the emergency starting and you can enter it by scan tool. So you need to save the 4 digit PIN code first, then you can inactive the immo for 30 seconds for starting the engine in case of immobilizer failure. For the 6 digit code, you can get it from the dealerships or some vin to pin software.
@@AutomotiveDiagnosis So WHERE do we get 4 digit code from, Please???????
@@hitone4319 4 digit PIN code must be registered by OEM scanner to the immobilized control module. It’s not something that you can get from someone. But you must remember this code is different from the 6 digit PIN code that we use for the key programming.
@@AutomotiveDiagnosisThen that info is useless as I don't and can't have access to the 4-pin code.
The 6-pin code won't be of any help as it cannot help with starting the car.
I thought I could program&reprogram the 4-digit code as needed.
@@iancasey1486 I think you didn't get the point. For programming the keys, you only need the 6 digit pin code and you can do it with many different scanners or key teaching devices. the other code (4 digit) which is used on Hyundai & KIA is only for emergency starting, only if immobilizer is not working and you don't have access to any help. 4 Digit pin code is not used that often and you can't use it for Immo general operation!
Dealer won’t give me the pins numbers then what can I do
May I ask your car model?
Hi yes it’s from a previous car that I had and it’s a jeep Wrangler and yeah, the dealership wouldn’t give me anything so they had to do it
Thank you so much for your support and knowledge
I will look into it for you and will let you know if I find any straightforward solutions. Normally there are a couple of different ways for finding the code, some tools read the code, there some software and some websites. Anyway I will check it for that model.
how to fix p1678
This fault happens when there is a problem is PCM and Immobilizer unit communication. So you need to check the Immo connector, wiring between Immo and PCM. You may have faulty Immo unit or PCM too, but check the connectors and wires firstly.

How did you get the password on a used car
I got the password from the manufacturer's technical website.
