- Ignition Key Transponders
Describes the workings and applications of modern automotive key transponders. These tiny chips transmit a digital signal that's then processed by the Anti-Theft (antitheft) module. An OK signal or command is then given to the ECM and related computers to allow injection and starter activation. Learn how they work with this clear and concise video. Future videos will detail what to do to reprogram ignition keys. Each manufacturer is different and so is each procedure.

Nice video. .... I am an RF Engineer, and the way you explain the basic function of the system is simplified so the layman can understand. ...... Nice Job.
Thanks for all the videos Guys! Dont know how people would dislike this! FREE knowledge! Keep it up!!!
*2021 we learned from 11years ago, awesome!*
You know when you just randomly start wondering how something works? Thank you Computer Man lol
Thank you, I appreciate that. It's been my pint after many years of writing and editing to do just that, simplify automotive technology for everyone.
Thank you so much! I just fixed my Nissan Frontier work trucks ignition and it wouldn’t start.. found your video.. separated the old key and put the transponder on the ignition and the new keys work 🙏
Great,

Couldn't you just bypass the antitheft module? Wire power directly to the starter and ignition?
Great news... Yes, most manufacturers need a min. of two keys programmed into the system. Good for you...
This is awesome to watch when you’re high
Great, stay high
Thank you, all we ask is that folks post and participate. Thanks again.
I know, but depending on your car's brand, some are not as bad. I don't really like when you have to use their scan tool to program a new key. Thanks for posting.
Informative video. Thanks ! 🤔🤗
Great
Thanks that's amazing great video channel I like it Nice I dea I respect

It's not about insecurity, it's about money... These videos are FREE for all and we need to keep then cost effective for us to make.
On older GM systems with the resistor pellet yes. See our video. On newer systems there's a low tech way to disable the transponder key system, but NOT REALLY. What you do is remove the coil ring around the ignition cylinder, take the transponder key and take the two together. Hide to whole thing under the steering column. Then use a regular key to always start the engine. This system will NOT work on some new models, since the computer does a rational check & knows the tampered system.
Did the engine start? That's good for you. have never had a viewer with a post like yours. The 2006 and older statement makes sense. Most systems have the AT module separate or it's a lot more complex system. Thanks for posting.
Wow...I really like listening to the robot voice narration and pronunciation of "trans - pondder" or "mod - joool". What country are we in?

No, you don't understand. The ECM and/or the key transponder module talk to each other. Often, the TM is also the ECM. This is a fully integrated system. To adapt this to old car requires also changing ECM or reflashing it, plus adding extra components. Thanks for posting.
That Black thing is broken in my Toyota Etios Liva 2016 ( India ) , they call it as Transponder key assy. No clue how that broken, and the dealer convincing me that it doesn't comes under Warranty, is that true., , ?
I got all the parts now. I looked up how the donor car worked. Seems all I needed was the ignition housing, switch, transponder under the steering column and the harness off the original vehicle. The ECM was not part of system.
I will install it and let you know how it went.
Thanks Mark...
very educational, thank you
Thanks for sharing.
The thief one thank you for advice
Very informative,thank you.
Can any one help have a 2002 Volkswagen Jetta VR6 recently did the heater core how to take the dashboard out and everything got it all put together it's about 2 weeks I had the battery disconnected and everything so I go put it back together everything and I go to start it and it starts and then the it just shuts right down cuz it's not reading the key or whatever, immobilizer is activated that's what it says on the on board diagnostics system
I just bought a 04 maxima n my kid lost the key same day. There are no extras I think the column apart and on the bottom of the ignition there's a couple of numbers looks like could have been written with a white out pen will those help me at all also is the cut from the door the same as the ignition and one more thing my friend has same kind of car that he's going to junk because it was in an accident can I take out his ignition and door locks and just swap them and will that transponder key work it's the same here if not what can I do with that

I't made my day when I found out my 07 FJ has no key transponder! I ordered 2 2008 keys with all the electronics inside for 50 bucks and just to get them cut and I programed the remotes, all done. The dealer wanted $350 per key because they insisted the 07 FJ has a key transponder.
So if I understand it right, I need the key, ignition switch, and the decoding module to install one in an older vehicle that does not have one.
I got the ignition switch, keys from a salvage yard and will go back to get module under the steering column with the wiring harness as well.
It doesn't work like you think. The key cylinder induces and powers the key-transponder, which is inside the key. The cylinder magnetic flux-waves have only a specific range to power the key-transponder. You'll have to tape the old transponder to the blade key. I've seen heat shrinking tape being used. Good luck and hope that helped.
Very informative ;)
Very Educational
You need an NGS Ford factory scanner to do this procedure. I'm sorry, but that's the only way. A locksmith company if they have the tool will be able to do this. Call someone else. Good luck.
Hey how can I take out the ignition key transponder because I want to put a ignition bottom star but I don't know how can I take out the sensor key ,,, can you help me with that ..?
The issue is that the ECM expects to read or see a DIGITAL CODE from the key. It's in the programming of the ECM. So there's no way around it.
2007 Jaguar keys suck, but they are really easy to program.

GM uses a rolling encrypted code too. Can not copy the key, need to buy an expensive replacement, and program th ecar to it.
12voltvids Thanks for sharing.
It started after I programmed the new cut key. Which tells me its working, cause the new key would not start it till I used the two original keys to program it.

Am I mistaken or are you making the coil around the tumbler and the coil around the key with the same circuit? I don't understand how a simple wire can imitate a powered coil and transponder. The coil is powered on, and the key responds with some stored code. I understand that you're replacing these encrypted signals with simple voltages that are then passed through the relay to the ECM. I just can't understand how the same loop can be used as both the "transponder" (key) and the induction coil. I feel like I must have missed something in the wiring to the relay, but I can't figure it out.
1999 Ford Securilock Pat w/bad cylinder. Two transponder keys. Does a cylinder need to be installed to use the induction coil bypass methods. As in affixing key to ring and actuating via standard key, heat shrinking transponder to dummy. Simply mating transponder key [plastic intact] to blank was no go. What would you suggest, new cylinder and code to old keys? We disagree on when a scan tool is requisite. We abla Ohm's Law and are confused by 'coding/recoding cylinders' Thanks.
Question would be how can I magnetically read and or ohms resistance on the transponder. 2010 Ford Focas. Stupid my key is all I have. Not the administrator key
You need a key that is cut to the ignition cylinder that you have. Then, using the equiment you reprogram the new key or whichever key you have to the Passkey computer. Having done this many times, I can tell you that the key-computer circuitry could be in the ECM, Dash-Module or Body-Module. There's a book that is also needed for this operation. Even if you have the Scanner you need this book. Locksmith people that do this kind of work should have all they need. This is something you can not do

How are things going with buying new key box ? I have the 99 audi but i wanna buy the facelift key box which has 3 buttons for lock,unlock and trunk(which i wont be working ofcourse) ? Can i just place that chip inside the box with the key or how's the wiring going inside ?
Hello there ADP I have a 2003 VW Bettle and I have not been able to start it? I re did the whole engine a overhaul I was only able to get it of the shop to home and that was it? Any suggestions how to get it back to normal?
Good info ;P
Well it went in just fine. Seems only vehicles 2006 and older work, because they use 64 bit in newer cars. The older ones use 32 bit and dont tie in the ECU on fords.
I did makr sure I got a 3rd key made cause you need 2 to program a cut blank.
Good post about Both Side Normal Key Cylinder!
Actually they aren't all the same, all use different protocols. The most secure are challenge/response transponders.
These anti theft systems are more of a pain in the ass to the owner who loses their key.
Just another damn expensive thing to replace when it busts or gets lost.. hey not all of us are rich! stupid car manufacturers >:(
grettagrids Rich or not it's here, so we have to deal with it. It's all made to offset insurance premiums. But it's on us now.

This crap doesn't make my insurance cheaper, even on an old car.

These modern transponder keys and remotes are fantastic are okay - until you lose one. Then yiu're so screwed it's not funny, We have to ask ourselves, is all this modern "convenience" any better than pulling a kay out of your pocket, inserting and turning it?
At least you can get those copied.
+Shineymcshine79 This has absolutely nothing to do with convenience. Its a security feature. If someone tries to force your vehicle to start so they can steal it, they have to find a quick way to make the ECM think it's getting the security codes it needs. What could possibly make you think this has something to do with convenience?
HDLCinCDragon I dunno, but unlocking the car just by being in proximity of it seems pretty damn convenient to me, don't you think?
Edit: Apparently I'm thinking of smart keys, my mistake. Even transponder keys are fine - until they fuck up, and we're back to my original point.
+Shineymcshine79 Well, you get get them really cheap on the internet and get them cut at a locksmit for really cheap then program it yourself. Depending on the car though. Not all new models are like this. I hate them myself. but my key is pretty cheap. Only 8 bucks.
what kind of system does a1998 dodge caravans have

Fiat Transponder keys are the worst. They uses rolling codes. They are the only ones that use programable RAM chips. Other car marks like VW, Ford etc use normal non-programable ROM chips.
Apparently when you insert the fiat key in the ignition, it uses they code from the last time you used the car. If a key warning light appears during driving, the key is being re-programmed with a new code and is showing an error due to voltage inconsistencies or magnetic fields corrupting this new code transfer to the key. Weird huh?
Corrupt transfers can occur meaning the next time you start the car the corrupt code is not recognised.
Incase of this a code card is required and a mathematical procedure not for the fiat hearted is required. Emergency start up.
You insert corrupt key in ignition. Press the gas pedal until engine warning light goes after 8 secs out then appears flashing. The number of flashes is counted and must correspond to the first code digit on card. Then For next digit, do same thing as before only engine light goes out after 4 secs and flashes again giving a different figure.
Its really complex, I have a science degree and don't understand it.
Why is it so complicated in car nobody would really want to steal?

Hi I own Mazda MX5 2004 convertible 1.8 petrol I replace a battery in my car after that it did start couple of time then once I left car key inside the key hole all the dash lights was ON, when I come back I saw "car with key" Dash sign is flashing since then car is not starting I have checked all fuse they all good but no matter how may time you turn the key car is not starting just a starter motor turns the engine wheel but not running I have checked spark plugs no sight of petrol there also checked Petrol pump there is also no 12V present it's look like immobilizer is cutting off the fuel system I don't have a remote key fob just a normal Mazda key can someone tell me the quick solution to start this car
Looks like an antitheft issue. If you replaced the battery and didn't use a battery saver, then all sorts of issue may come up. You need ot go deeper and scan the vehicle.
I have tried scanning Even the OBD2 is unable connect
If there is not OBD-2 then your ECM is dead. Check the 5 volt reference to see if the ECM is awake, sleeping or dead.
I have an MX5 Mk2 and lost the little black transponder thingy. Local dealer searched his data base and said that he had never seen one like it.It's about half the size of a little finger. Any hacks around please?
It will help if you can post pictures of this part
When your cars key is worth more than a car worth stealing. This is what I think is theft by proxy of car manufacturers?
