I just messaged you on ebay hoping to get a compilation of supplies to bypass the key, and add a push start button on my 2003 nissan extera. Thanks so much for the video!

Great tips feels like going back to the good old days 😎😎

this man knows what he's talking about, gave me the smartest advice I've gotten yet, and my car has no issues as a result.

To all the ungrateful people who complained. You're getting valuable information for nothing , go to the dealer and spend a $1,000.00 bucks if you feel the man chatters to much. Why can't you be grateful and thank the guy instead of finding fault ?

Thank you profesdor. I'm the guy who had an key on a ring with the newer functional key while i trying to reset sfter battery problems.

holy heck.....you sir, are a total legend. Most helpful information

Very informative. Which ones would I need for a 96 mustang gt? I looked at your site but don't want to buy the wrong ones.

Good video, well explained, friend Lessco, how can I do to disable the safety light of a 2006 Dodge Ram 2500, since it blinks and does not allow the vehicle to start, besides how could the data bus to the PCM bypassing the cluster , I would appreciate if you could guide me to resolve the situation, thanks in advance, Regards.

Thank you very in depth informative.

u have great information maybe try this one. i have a 1993 camaro v6 3.4l. i lost thr key so i took the lock cylinder out i can turn the key over no start. i bought a baker electronix vats bypass module. the instructions say attach the wire from bypass module to dark blue fuel enable wire coming out of the vats module on the car. my module has both 30z and 50z i hooked everything up like they told me it atarts and runs for 3 secs and dies. any ideas on how to completly bypass all the way around or am i hooking it up wrong or another location to install the module at

I know you have alot of comments on this post about if this woyld work for each persons car. I was wondering if a toggle push start button would bypass the need for a key or if it is even possible to link in your relay system with the push start.

i purchased a 555p ford pats interface for my 1998 ford expedition could i use the same principle to use on my expedition

Before I slice my only key, do you sell anything I can use for a 04 Dodge Ram 3500? You have great information, Thanks!

Interesting. If had installed an aftermarket ecu can I just bypass it at the harness? 07 triton 4.6

Do you have what I need for a 1999 Ford Explorer? Thank you

would like to buy the databus bypass module and standard relay and socket for a 2000 jeep grand cherokee..my problem is exactly the same as the one as described in the video

hello dear , thank you very much for your video, i hope you can help me with my car, its jeep liberty 2012, without a proper knowledge from me exceeded the 5 times try of the sentry key, and now the car wont crank at all, and the red indicator under the braking light is flashing while im trying to turn on or during turning on the ignition key, so how to reset this and, by the way this is all because i think my sentry key is faulty or something i don't know, but if i could just rest it back so i can diagnose the key issue it would be great thanks dear

If you don't have an original 'chipped' key. Missed the part about 'How' the new flushable database interface is 'flashed' with the proper 'secret code' that the computer needs to let the car start.

what module do I need for an 08 cobalt ss tc, passkey3+ I believe?

Hey nice video I bought a 2001 ranger 3 weeks ago I have three keys to it the previous owner said he had to put new computer and get keys for the truck before it ran find now no crank I turn one key to start position theft blinks rapidly the other two keys the left light goes off after 3 seconds still no crank battery is good I can hear the fuel pump air bag light now reads off when truck ran air bag light was on could it be the keys/ ignition problem or the computer/pats can a locksmith repair problem or is it a take it to the dealership situation will I eventually need to buy the set up you described in your you tube video if you can respond I appreciate the help Thanks

Any thoughts on defeating the immobilizer on a 2004 dodge/Mercedes sprinter? I went to the websites you mentioned and did not find anything that would fit my vehicle.

Hello I need help with my 2001 Ford Mustang basic coupe. I lost all the original keys and just have a standard key made at the hardware store. Can I order the same kind of kit or/and bypass for the Ford Mustang

thank you for all the Information , now i shall go and get the kit and crank our beloved Betsy ( 2001 Nissan pathfinder SUV ) been sleeping in the yard for the past 3 yrs , time to get her new tires and flush fuel tank and lines and engine , radiator ,e.t. c . because my girlfriend lost the only original key she had , and i have been looking for simple solution to this problem . and i found it here . this will save me over $798 USD . I have one question to ask knowing Nissan uses CAN bus system , thanks in advance : do you think according to PDF catalog the IM05 class is best since i have no key at all ?

Would this work on a 2004 Jeep Grand Cherokee Laredo 4.0 with their Immobilizer system?

I have a 2000 Ford Expedition Eddie Bauer Edition and my transponder in my keys went out. Is there a way around the transponder or do I need to get new keys made at the dealership?

I have 01 Expedition Eddie Bauer with the MACH Stereo system I just bought a Kenwood eXcelon ddx394 SAT the settings won't save? i bought a metra wiring kit for my car but still wont save?

will this work on a 2006 grand Caravan sxt 3.8L I want to use a standard non chipped key. i have one original but it's to bulky to carry around.

Ok im having tge same issue for weeks now ive been daignosing trying to figure out why the coil packs werent getting spark..the engine would crank but no spark, fuses ,relays are all good ..so now its come to this the egnition switch...i just ordered a new complete ignition switch w/key for a 3.5 altima now if i install it will this resolve my issue or does the computer/ecm need to be programmed to that specific ignition..im hoping to just bolt it in plug it in and it just be ready for use..lmk wat u think thank u!

If you don't can you recommend an immobilizer that would work on the 2003 Expedition without having to add a remote start??

what do u advise me to buy for a 2011 subaru wrx impreza

I have a 2003 eclipse that we turned into a race car. During the build I guess we did something that it went into anti theft mode. Turns over but no spark!!!! Any advice????

Hi I have a 2005 jeep Cherokee a SG liberty and she broke down 3 years ago. When I had a technician put a computer on it. It come up with the ignition is not responding with the ecu the ecu is not responding with the body module and more. But when I turn the ignition on the fuel pump comes on but the immobiliser won't disengage and the only way I can get her to to turn over is by touching the live from the battery to the relay slot for the starter. Now jeep UK has estimated close to £3000 for all the parts and that's twice the value of the jeep and it's a shame to scrap it it's only done 70000 miles is there some way I can get her going for penny's? I have both Keyes.

I've got an 04 Ford explorer and which it has the pats security and I've bought three individual keys now and now I'm going to have to buy another someone please tell me how to bypass the system or find a solution to what is causing the problem thanks for any advice

Hey I'm also in desperation for help with mg 2003 mini cooper s lost all keys . Can I order the same kind of kit or bypass for my car?

What’s up brother? I can’t say enough about the help you give, it’s awesome. Your hardworking and dedicated. I have a 2001 Sierra, power locks but no AU0 code. Has factory theft system though. However I have a encore e1 I’m trying to hook up. Do I need to have it flashed, or can I have any schematics? And how do I send you a personal email?

I need to buy a bypass module for a 98 Ford contour. I have none of the keys anymore. Can you help me with selecting the right one?

will this work for my mercedes E230 98? It appears it has a DAS (driver authorization system). Lately my car doesn't want to start, I suspect its the DAS and I need to by pass it.

We like to do this for my Mazda rx-8 2004. Any special requirements to accomplish that? I have the old ignition transponder ring but no key I’ve put a new ignition in there that has a key. I’ve used a programmer and checked it says it has no keys tied to the immobilizer. What would I need to do to finish it or to work around?

Interesting , trying to help mom get her 2002 Volvo started . She ordered a passkey , it fits . Would your method work ?

my 1997 mustang gt has a problem starting. it cranks, the engine is on and then immediately dies. tried many times to start but same issue. Also, the oil pressure gauge goes crazy up and down when i try starting the car. i thought it was pats at first, tried few procedures to re set the system but to no avail. since my theft lights is off all the time, i am not sure is pats (unless the theft light is fused). Other thing i noticed is that i could not open my door with the key itself only with remote. after few tries finally managed, thought this could reset the theft system but still the same problem, car shuts off soon after starting.. what could it be?

Just watching your video now.. Have you ever encountered a 1999 Lexus gs300 with an immobilizer amp intermittent malfunction? At least an older Lexus with that issue?

Are you familiar with the ews system on 03 mini cooper?

Hey bud I've got a 2002 vw jetta. The anti theft won't let the car start and continue running. Can you please show me how to immobile this. Thank you for your time

hi, I have a 2002 ford taurus and I think my PATS has either gone bad or something is going on with the car, it would randomly just die while driving, only while driving, not sitting still or at a stop. some times it will do it about every day, sometimes it will go several days or a week or so with doing it, the engine just stops, no stuttering or anything and all other electronics still function, after the engine dies, you can turn the key to off, and then crank the car right back up most of the time. a couple days ago the keys stopped working to start the car, the engine wont even try to start but all electronics still function. I was wonder if this bypass might work in my situation and if so could you help me find the correct databus bypass for my 2002 Ford Taurus? its the 3.0liter duratach DOHC engine. I have gone to the websites mentioned but want to be sure to ge the right bypass because I am on an EXTREMELY limited income thanks for the help and the video. chrislouck@gmail.com
