How to make a cheap transponder key bypass

[@ilike2seeit]

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

[@Skwisgar2322]

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

[@bbrennen13]

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.

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.

amen on that

[@garyderoy]

For my wife's Chrysler I taped her transponder key inside the steering column cover and she uses non transponder keys - no problems.

[@jasonguidry8211]

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!!!!!

[@alloutofdonuts3998]

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!

[@GG-od2tr]

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.

[@candiceflynn74]

@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 💔

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

[@The-professional-tire-kicker]

This shits no help

[@meathome3344]

Thank you Lessco electronics. Great video. I did not need a remote start so I did the same thing without the relay and wiring. I just soldered the ends that would have gone to relay together. Placed the wire around the ignition and key then hid the key in a concealed location in car. Now $2 keys all start car and original key is not damaged if we need it in an emergency. Zero money spent.

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.

buddy this is just about what i was looking for

[@Lesscoelectronics]

[@danielheffelbower7919]

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.

[@Natures_Symmetry]

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.

[@elivios]

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.

[@Natures_Symmetry]

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.

[@danielheffelbower7919]

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.

[@elivios]

Daniel Heffelbower thanks

[@Razorsedgeartwork]

The relay is 100% redundant. There's no "maximum reliability" when you're adding in another part that may fail in lieu of a piece of wire that can't fail. All you're doing is extending a loop around the key and having a relay in the middle for no reason. And a cars computer won't have issues with having 2 keys and 2 chips close to each other. They're passive systems to start with, they're only energized during starting. The ring's field extends further than the immediate area, having 2 keys on a ring will both be in the field. As long as 1 of the keys is returning a known code the engine starts. That's it. If not anytime you bought a new car you wouldn't get 2 keys on a ring, you would get one on a ring and one in the trunk so you wouldn't have cars shutting down randomly on the first drive home.

[@supernaught1963]

[@Lesscoelectronics]

I never expected this video to be popular with locksmiths, I do this for the average guy looking to save a buck

[@GrantLackey]

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.

[@rikkilee9409]

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

[@Ralph336]

I want to order this today!!!!

[@Gaffok3]

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.

[@thomasmalatesta378]

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.

[@Lesscoelectronics]

This needs to go under the driver dash and the loop I show needs to go around the transponder ring at the key tumbler.

[@bradhansom4362]

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

[@Alex30013k]

This is what I was after, as you cant just stick the chip to the key barrel as my car wont lock if its senses the chip is there. Brilliant!

[@ranietsd1]

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.

[@believen_uboo3705]

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.

[@ricksparrow3872]

after you have done this procedure can you change the ignition key cylinder with a new non anti-theft key cylinder

[@Lesscoelectronics]

What I would do if I were using this tecnique is I would use just the chip in my one and only valid original key and leave the metal key part out of it, It's not needed anyway (just the transponder is), and wire the bypass so it energizes with ignition.

[@simonvqst]

for anyone that dosent know, you can use this for remote starting, and have the relay only output the signal when the remote starter is active.... this actually isn't pointless whatsoever

[@mauriciomagnovska8840]

or you can just get the transponder off the key and glue it close to the tumbler

[@learningwithlyricsandsongs]

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

[@amar1w1]

some transponder chips break easily like vw

[@jasonguidry8211]

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

[@relik0fages]

Wouldn't it be easier just to pull the transponder from the key and glue it near the ignition?

[@hikeven]

***** That is not true. After you pull out the key out of ignition, car wont communicate with chip anymore.

[@relik0fages]

Lessco Electronics I just think it's really stupid to have another key left in the car. Especially if a car jacker knows what to look for. Then you've pretty much just handed them over the car with little to no trouble. As with the transponder, I just removed the chip from both of my keys.

[@romansten9]

yes! but even easier than that. secure the whole key there! just hide it with tape or a plastic housing. forger all this extra work!

[@jonathantatler]

+relik0fages Sounds easier to me! Although you do now have a car as easy to steal as an old ford that only needed a nail file to start. Or you could order a new key? Only saying

[@relik0fages]

Jonathan Tatler Have you ever tried to start a car with a nail filer? The point of my argument is, why would you leave a second key in the car? It has to be hooked up to the terminal and remote starter. While someone previously said to tape it some where in the car, all you have to do is follow the wire and find the key. Where as removing the chip from the key and taping/gluing it near the ignition is safer. Unless of course you have a car that auto-unlocks if the chip is in range.

[@thaddeusmcgrath]

I spent 250 bucks on a new ignition switch I had two new keys, I left my key in the ignition to avoid losing it having a different code key not matching my current crank key that would throw off the current crank code on my key ring. As a result, two summers of baking in the Ga. heat, screwed the transponder key down to one. So chose wisely on were you find a permanent place for your key, the transponder cylinder inside the key is full of a type mineral oil, direct sunlight will kill it!

[@enoxosr1]

from what I gathered, yes, he used the original key, since that key is needed to send the wireless signal to the bypass module. If you do not a key at all, this method will not work for you. Only way is to bring it to the dealership or bypass the ECM (complex stuff).

[@davidgurney3639]

I did not have the original key or key fob for my 09 pontiac g6 I did this method and it started I took my car down the road and back.when I got back I turned the car off .I then tried to restart my car and it wouldn't start back up.idk wat the problem is.

[@SteveWhiteDallas]

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.

[@daledavis-mg6wc]

[@rikkilee9409]

you can hide a ghost switch to interrupt either 85 or 86 on the relay so your theft system is not compromised.

[@jameshenrisson2782]

how about getting a standard metal key cut. then cable tie the transpodant key to the key reader behind steering shroud.

[@panchovillaxx7]

Wouldn't be easier to use 2 wires and a push switch from the starter? Turn the key to acc position then click the switch?

Please clarify, the transponder key you are using can be ANY vehicle, not required to be the one you're in?

[@incubatork]

why not just tape the key inside the plastic housing out of sight, same thing quicker and less faff, or take the transponder out of the only key and tape that inside the plastic surround. No need for relays, wires all over, nothing

[@rodx5571]

What you propose would not be a bypass, and if the HALO fails (tranceiver antennae around the key hole) you are stuck. just dont lose your keys.

This!! This is absolutely ridiculous and could be done so many other ways much quicker!!!

[@acs4llc]

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.

[@rodx5571]

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.

Or, remove transponder ring and tape transponder key to it in the correct position. tuck assy behind ign cowling.

Most European cars have the transponder ring behind a trim which means the "mod" is invisible to the naked eye

The remote for my 2003 dodge caravan doesn't unlock the doors... in fact even the electric lock switch on the doors doesn't lock or unlock the doors. But if you remove a certain fuse (I don't remember which fuse at the moment) and re-install the fuse, the remote and the door lock switches work for a short time but go back to not working.

One important detail is to cut off or grind the shank of the key. Some thieves know this bypass trick and know there is a useable key 2 feet away from the ignition lock under the dash

[@howdydoody30204b]

This is certainly an option, and I appreciate the video, but it turned out to be not what I expected. It seems in the video that the only key and the key cylinder are always connected together with that 3-4 ft. wire. So the key always remains in the car, not to mention the aesthetics of the whole thing with the wires and all. Am I interpreting this correctly? Also, what kind of key are you starting with? If you don't have a key, which is the scenario that you are illustrating, then you first must get a key cut for the car. That means giving the dealer the VIN and proving that you own the car. That will cost $50 to $100, as far as I can tell. It will open the doors and turn the ignition lock, but it will not crank the car as it has not been programmed. So the cost would actually be $10 + $50 (or more). Again, am I interpreting this correctly? Thanks for the video.

Haven't try this but technically it will work as the coil you created will send signal to the electronic receiver. But why not just zip-tight one key with working transponder INSIDE the steering covering near the ignition cylinder?

[@TheGamer0451]

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 ?

hey man, we are very happy to have you, hoping you could help as well;my ECM is fried out due to battery inserted the wrong way, I just received a new one shipped from the US to Chad but no electricity on the injectors when I tried to start it, what do I need to do, some guy tried to program the key but it is asking for pin code: It is a Chrysler 300, 2005 model, v6 3.5L, VIN 2C3KA53G77H611942. THANKS

If you have the original key why not zip tie it in a distance were the sensor will read it. I am down to my last key and went through drilling my ignition switch out with a 1/2 " bit, using a flat head screwdriver and having the key within a few inches for the sensor for the computer to read for starting engine. I know if I can hold the key that distance you could find an close enough spot on your steering column to tie the transponder key under the shroud.
