In this video I explain immobilizer system. I show you all the components on the car, I remove them and explain each one. I also show you how to find the transponder chip, how to buy a new one and how to program it. I also explain the immobilizer bypass procedure and this fact that you should or shouldn't bypass it.

Hey this is a long shot but my car was recently broken into. All they did was steal stuff and then smash my immobiliser transponder coil. I've been searching all over for the part but it seems to old to find another for my car. I was wondering if there was any way I'd be able to build my own coil and reconnect it. Or any way to fully disable the immobiliser.

@alanpatterson2759 4 ай бұрын

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.

@AutomotiveDiagnosis 4 ай бұрын

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.

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

@AutomotiveDiagnosis 6 ай бұрын

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 5 ай бұрын

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.

@AutomotiveDiagnosis 6 ай бұрын

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.

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.
