How to make a cheap transponder key bypass - Costs under 5 bucks! Save yourself all that money you'd give to the locksmith to repair your transponder chip key anti theft system.
Hi, I know this was made years ago. I watched this vid again slowly 2 times and now I completely understand this system!!! I used this method on 4 bmw's a mercedes a honda and a dodge truck and it works on all and is loved! So easy!!! Thank you. I watch many of your other videos
the direction you hook a relay up can make a difference if It has a Fly-back diode to suppress negative voltage spikes when it is disconnected. a relatively small inductor (which is what the solenoid in a relay is) can generate hundreds of negative volts for a brief instant when it is disconnected, the diode limits it to about -0.6V
thanks. i have wrecked car i bought a wrecked 2003 f350 w/valet key only. i just needed to hear engine. not worth $300 for locksmith. this did it. thanks again.
Very good video, you just have to show the connections with a little more detail to be able to grasp the explanation well, the rest is very interesting because it saves us money, now this scheme works for Dodge pickups too, Regards.
On vehicles you always ground to the frame (basically any metal objects that are connected to the frame). The Negative power is run through the metal mostly to save money but there are other advantages as well. the majority of wires under your dash will run positive power. Be careful when working with these wires, If you let a energized wire touch the metal it will likely just blow a fuse but can result in serious damage.
So wait, you still need a working transponder chip or key w/chip? I need a solution for eliminating the immobilizer permanently. I have 3 working keys but the one with e chip is lost!
I feel you misunderstood He clearly states creating loop with wire and a relay to create high frequency you will still need a key without a transponder the 16 likes are also from people that will never interpret how a wire works when energized.
@Dean Lopez No you're 100% right... You would need one chipped key... This could work with a broken chipped key or as a preventative measure to avoid getting locked out in the case you are unable to afford to get your transponder key copied. You won't lose the one good key if it's wireduo and hidden in your steering column, and can easily afford a non chipped key 2 use daily with this method.. This won't work if you've already lost your only key. Womp womp wooomp 💔
Old Cup And String Concept! I've watched on repeat multiple times. With what ive learned from building the bypass I feel 85% more confident testing fuse boxes and relays. Before id just get readings and see if the relay sounded off...... Thank you so much!!!!!
a perfect example of additional redudndant wiring that will more likly cause faults in the future, just attached the little transponder to the coil reader... Simples
this is an excellent video and technically precise as far as I am concerned...too many neophytes on here do not understand some item in particular and blow off steam
Of course it will lock! Just put the key in the lock and twist it ! That's how it was done before remote controls were invented, but these days it's obvious that the more gadgets that are made, people stops thinking and get more and more stupid.
What this device is good for is a transponder key that still has a good chip, but the key itself has broken off. You can try taping the transponder housing near the ignition, but you have more placement options with the coil, therefore you're more likely to find a placement that the ECU (car's computer) will accept.
I bought 2 new uncut "chipped" keys for my car off Ebay ($5.50ea.), had them cut at the locksmiths shop at work (free), searched the internet for instructions on how to get my cars ECM (Engine Computer Management system) to add the new keys RFID codes into the ECM's memory and viola! Simple as that. Each key has an RFID chip in it that has a programmed ID code already "burned" into the chip. no two are the same. With my car, it requires that you have one valid key that has already had its RFID code stored in the car's ECM. The ring you see in this video is an antenna. When you turn the ignition on, the cars ECM pulses a signal thru the antenna and the RFID chip returns its code to the computer. If the code is stored in the ECM's memory, the anti-theft circuit then gives permission for the ignition circuit to be energized which will allow the car to start. If a non-chipped key or a chipped key that has not been stored in the ECM is used to try and start the car, then your engine is just going to crank over, but not start.
Hi, I did this in my 2004 Kia Sorento and it worked like a charm. Thanks for sharing. I live in the GTA (south Ontario), and when the temp. drops below -10C, the car will not start with the remote. I have isolated the problem to the immobilizer bypass, since it will start if I go in the car and start it with regular (chip) key. I proved this by trying to start the car with the valet key when it's below -10C, and it won't. It's letting me down on the days when I really need the remote start. Any ideas how I can fix this? thanks.
In order to do something like that, Youd actually need a mobile key cutter or alot of trips to a cut cutting place! As long as you have one valid transponder key, You can do this to any car
Can this type of setting extend the communication range or distance between key and transceiver to let's say 1 meter? I want to use that on modification to push-button-start system.
Hey DUDE a really great job. I Just so locksmith's comment admitting that this thing really works and saves money to people. hahaha. never mind his comment on security lack after installing this. if you drive just a normal car and especially if you pay a decent insurance for the car this is a great great thing if you loose the keys. Thanks again my friend.
hey just a question I want to know can use use a key that is all metal and no transponder on/in it say i have one cut from a key cutplace or pick set to unlock it can i wrap it around the pick set. I repo cars and this would help allot if i can sort it out with alligator clips and tempoary set ups . that way we can drive them back to the lot not drag them on the back of a flat bed truck bed. thanks for your video great stuff. make more video's they teach allot of good information for us.
is a very good video for anyone wondering it seems this is for those trying to get new keys to work with ecu`s or new ecu`s with keys as that can cost to code in. maybe so I hope this works thanks for the vid QUESTION:- when you say "when you put your key into ignition it needs to be hot " what does that mean i`m from the uk England and cant quite get what exactly I need to do and look for in this part thanks
Genius. Now quick question, will thus work on a 2003 ford f150. My son list his only key the day I have him the truck. Grrr. Now I'm moving and have only a few days to figure out how to get a new key and get that beast moved.
So is the key attached to all of the wires and the relay its not gonna be very comfy in my pocket but it really beats having to pay 300 bones to the stupid dealer
great videao, clear and precise. i have just bought andriod 4.2.2 and this has a brown wire. would this be same as green in your video. also would you please send the link to relays. i have been told about self powered relay for canbus wiring can you help on this topic. i have just bought mercedes viano and this keeps on throwing errors on dash with canbus issues. i installed two rear number plate blubs that i replaced with smd/leds and got the message on dash "check………. blubs" thanks in advance and accept
sounds lto me like the key sense wire on your key tumbler is loose or disconnected, check by looking at your instrument cluster, see if the door icon is on or not, that tells you right there
keep in mind that in cold climate it may work when it is warm out and may not work when it is cold the signal from the chip is proportional to temp. you can also take magnet wire from radio shack and wind it around the chip and cylinder and connect as you show tripin the relay with a crank wire 85 and a neg. key sense on 86
My boyfriend has a Chrysler Sebring and I have a Dodge Ram 1500. My question is, can I program his car key to my truck even though the key for the car wont turn my ignition cylinder?
will this work for a 2004 Saab 93, think i need a new CIM module, but not sure, do you take apart the ignition and figure out which wires are transceiver wires, and then hook them up into the relay ...anything else?
Love your work matey and unlike a lot of the fools I can understand how this works (and now you don't need the original key as it scrambles the signal and tricks it to think it's the right key) bit my question is???? Can I just run from 86 on the relay to positive on the battery and then 85to the negative of the battery or does it 100% need the ignition wire ?
I've lost my holden car key and it has a transponder on it would this work? Instead of me having to pay them hundreds of dollars would I be able to just get the key cut and make what uv made? and it will work?
I have done the same thing by just removing the transceiver from around the cylinder, taping the old key to it, and tucking it as far under the steering column as possible.
Put a $15 combination key lock box inside the car or trunk, with the one good key inside of it. Buy some non-chipped keys for you and anyone else who needs to drive the car, or to keep aside for spares, to get in and out of the car or trunk. Unlock the key lock box and use the original key to start and drive the car, and lock it back up in the box when done.
I read all the comments but I still don't understand how the relay adds to the signal strength. Does the relay somehow feed some of the 12V to the loop of wire?
Hi, I'm not sure if you could help me, I have the correct key but I think the immobiliser part around the ignition block is faulty 1 wire had snapped I soldered it but doesn't seem to work now.
In some cars, (my car) When the key is moved close to the lock, I Hear the car come to life. Steering lock opens and many other sounds of clicking and ticking. It I were to tape my transponder near to the lock and just leave it there, I would drain my battery while it was parked. So, no. I couldn't do that. Best wishes
Technically Amazing!!! If you cant understand WHY he has taken certain steps you dont understand what DOING IT THE RIGHT WAY means. This lesson has opened a whole new line of thought for me
Hi! I am a locksmith, and yes, it will work. However, this is alot of trouble for it. All you need to do is glue your working transponder key within 3 inches of your antenna to "bypass".Yes, it will also make it much easier to have your car stolen because all one must do to start it is turn the ignition. Or find the key already in your car hidden under the dash. Also, this only works on "traditional" keys. If you have a prox key or the new chrysler style, it will not work.
I'm also a locksmith and that's exactly what I had in mind when I saw this. And there's way to to make it safer: Just glue the transponder chip to the cylinder, instead of the whole key. It will still be easier to steal the car, but it won't make it a whole lot easier for the thief if there's a key hidden there.
i did what you said on my 2002 ford windstar when i installed a auto start and it worked perfect. do you know if this concept will work on a 2006 saturn vue? and thanks.
Would work with any model, as long as the chip is in the range of the receiver. Not recommended though, it makes the car less secure. Too many videos of picking ignitions here on youtube. Spend some extra $ to make a spare key. Those chips are there for a reason.
However the vue does not use a transponder. It uses a magnet in the cylinder that rotates past the sensor when you turn the key. Not sure how you would "by pass" that.
Can you use this method on a car with a smart key and wrap around the antenna like a 15+ transponder located under the 2nd cup holder. Would I still have to wire up a programmed output to trigger the PTS wire like the BLADE AL diagram shows or can I get away with just using this bypass method and wire up all the ignition wires without PTS wire hooked up would let it remote start? Just curious if anyones ever tried this on a smart key PTS car
Does the key that I’m using have to have an actual chip in it or can it just be a blank metal on metal key or does it need the actual chip in it thats not programmed for the car
All I did for my '04 F-150 is put the key right under the ignition switch and it's completely fooled. Regular blanks work now. On this truck, you just pull the rubber grommet around the ignition and set the factory key right there. The original key just has to be close enough to the ignition for it to pick up it's signal. It's as if there's a place for it on my truck. It's true, the other original key won't start it now.
With the Ford PATS system the halo around the key hole that read the key likes to fail. if you only have 1 key this is one way to not lose it, but its easier to just guard the correct key with your life. And if the halo does fail, you are in the same boat as not having a key. my advice is just get a locksmith to cut and program you 2 more keys, cost about 120$ and you have keys to lose. AND you have a sure fire way to diagnose a bad halo, if all 3 keys wont start the car, you can be sure the halo failed. Got 3 ford at the shop right now with halo failures, F150, explorer and a Lincoln town car.
I have a 05 Nissan quest I changed the ecu computer due to problems with it . After installing a used one from the junk yard along with the ignition , car wont start and the code popping up when i hook the scanner up is (p1610 lock mode). Will this work for me ?
