I bought 2002 Tahoe on 2010 was installed with after market security alarm I used that for long time until both fob keys was bad so I decided to removed after market system and I start using original fob keys work okay but my Question is if I unlock the door with the key and open the door horn doesn't go off and the vehicle start normal is that normal ? my understanding is if we don't use fob key to unlock the door vehicle should not start and horn should go off please advice thank you and yes yellow security light working blinking and if i unlock from inside and I open the door horn goes off
Cut and joined the black and yellow wires and left the red one intact. I screwed up the sequence so I started again. During the second ten minute in the on position my battery died. I jumped it with another battery and started again but the second battery didn’t have enough charge I guess because it would only click on the second attempt to start it before another 10 minutes . Glad there is always tomorrow.
Did you have to take off both battery cables and jump them together to drain down residual electricity in the system before connecting the two wires, yellow and orange and then trying the key sequence?
I did this and my truck started but I’m not sure if this is the reason why because when I did this 2 weeks ago it wouldn’t. Start I then checked fusss and my TBC fuss was swapped from a 10 to a 25 I changed it to a 15 as that’s all I had at the time and did the 30 min reset and she started up. I’d anyone knows why please help
Man this all a sudden started happening to my 02 Silverado and the security light only comes on with door open but seems like when me or my boys mess with the lock it won’t start. Last time it sat for 24hours and it fired up and been fine til yesterday and now I’ve tried everything but this but trying to now waiting on the tow dude.
Dude! My 1999 suburban k2500 constantly would do this, no start. I too replaced the fuel pump and filter and no go. Followed your instructions cut the yellow, orange wires and tied them. Wow, started on first try. Security light even went out right away and doesn’t stay on after starting. Thanks a million for the info. ✌️
So help me out please I feel dumb. When you cut the yellow and orange...which side of the cut wires do you tie together? The two cut ends that come from under the dash or the two cut ends coming from the ignition side? Thanks
@lurpincutting4208 this fixed mine, I bought a passlock bypass kit on Amazon. Its just a connector that has a resistor plugged in one side. Just cut the yellow and orange wires and stuck them in the other side opposite of the resistor. Has started right up every single time
@@joerutherford407the cut wires off the ignition are dead. It’s the 2 off the main harness. Just follow where they came from and it shouldn’t be a problem
Thanks for this, I followed your instructions and I can start my 02 Escalade...I was stuck at a storage yard ..gonna give the resistor instructions a try since my speedometer is not working now..
Once your truck starts, just unplug the three wires. the security light will stay on but your truck will start every time. Will reset if truck loses all battery power. then do it again.
Getting a used steering column tomorrow from auto-salvage. Going to try changing out the sensor only, then re program the key. Hope it works. 2006 Hummer H3.
I want to add that apparently, at least on my 05 5.3, once you do this procedure it forever defeats the security system. Turns out I had a bad starter, but I thought maybe my bypass had come loose so I’ve had the wires unplugged while the key is out, while the key is on, everything and it never reverts back.
Worked perfectly on my 2005 RCSB 5.3. Black/Yellow/ and then Red w/white stripe. Put the black and yellow together and then did my 3 resets and now the truck starts like it should. Ty for putting up a good video explaining the fix for this common issue!
So I had a 03 gmc. Had the same dying issue. Noticed that the dome lights, power locks, power windows, and gauges were not working. Tried to connect diagnostic tool. Was not able to communicate with any of the modules. Ran out of ideas. Had to talk to a gm vet. He asked if the radio was aftermarket. It was. He advised to remove the radio. Disconnect the radio and the interface module if it had one. When I unplugged the interface everything started working and the truck started. So if your having this issue before you cut the wires check the radio.
I have a q i have a 98 gmc sierra i also jabe the same problem having to reset but not all the time mayne like 2 times a mnth but what i am having more of a problem with is it wont start without me pressing on the gas pedal several times while im starting it as it says in the manual but sometimes that doesnt work it jusy cranks but not start sometimes it acts like it wants to start but goes back to cranking my q is can this still be a security issue ?
So does anyone know if this reason causes the injections system not to work. I have fuel to the shradder valve and fire to plugs but no fuel to the cylinder
To permanently fix this issue you replace the passlock module on the ignition and have it reprogrammed. This bypass with correct resistor completely bypasses the junk GM ignition security system including the security light.
Yes security light flashing, engine tries to start but will not start. Leave key in on position (dashboard lights on) for 10-11minutes turn off and turn on again it should start. You may have to repeat these steps up to 4 times in a row to completely clear the security.
@You're a GOOF well I did what you have said and it's hit or miss that it works! Alot of it has to do is that harness is very loose and the pins are not making contact
Was wondering if by chance you know if this Works to bypass the vin locked ecm? I spun bearings in my over rated 6.0 in my 2500hd. I put a 5.3 in it that will eventually be on low boost but for now I just need to drive it NA. I do have the computer that came originally with the 5.3. I've been worried the same as you to hook it up it's now running ungodly rich on the 6.0 computer. Would love to have it be more efficient. It's probably worse than the 6.0 wad on gas. Lol
Wow bro i fr had my doubts that this would work. i have a 98 c1500 and replaced the vats module itself, ignition cylinder, and ignition wiring harness and still had the same problem, flashing security light it starts but dies after 2 seconds . tried this and after following all steps it fired right up after the 3rd reset thank you so much bro i was so tired of pouring money into my truck. TRY THIS IS WORKS!!!
You are the man!!!
Did this to my 2000 Silverado started right away thanks

what if your security light dosent flash ? 3:18
I think it’s fine I’m doing it right now

@@joerutherford407hello did you find out? because i’m now having the same problem

This shit is wack I can’t believe I’m doing this to my 104k lb7
Let’s see if the 3x bypass works i refuse to cut those wires
I have a 2003 chevy express 2500 4.3l. Did exact same and it didn't start. Do you know if it requires to use resistor and if so.. how?
Thanks for this, I followed your instructions and I can start my 02 Escalade...I was stuck at a storage yard ..gonna give the resistor instructions a try since my speedometer is not working now..
I have the same switch on my 99, what is it for?!?!
Fuel pump cutoff on my old truck but it could be anything to disable the engine.
Did u reconnect the wires or just left them sliced ?
Pretty sure my truck just shit out completely 🤣🤣🤣fuck, instructions not clear
Once your truck starts, just unplug the three wires. the security light will stay on but your truck will start every time. Will reset if truck loses all battery power. then do it again.
I unplugged mine and tried this, works for a couple months then had to do it again
This works, I really appreciate you posting this
Got dam can you be fucking still dam.
Hey I did that to my truck but that wasn’t the problem it was the fuel pump is there anyway I can just put the wires back where they were?
Getting a used steering column tomorrow from auto-salvage. Going to try changing out the sensor only, then re program the key. Hope it works. 2006 Hummer H3.
That switch is usually for a back up camera flip it a few times it tricks it to read the gear select
Thanks for the video! I have a 00 GMC Sierra and I didn’t have to splice anything, I just did the relearn once and it worked!
Worked perfect on 99 Chevy k3500 5.7, Had been fighting with it coming and going forever, Thanks man.

Sound like some shit
Hell yeah brother
PFI speed tuned baby!

Scrap it
To permanently fix this issue you should look at replacing the BCM and the TCB Fuse (bottom right most 10am fuse) in your under hood Fuse box.
To permanently fix this issue you replace the passlock module on the ignition and have it reprogrammed. This bypass with correct resistor completely bypasses the junk GM ignition security system including the security light.
does the motor turn over crank but not run I have a problem with mind
Yes security light flashing, engine tries to start but will not start. Leave key in on position (dashboard lights on) for 10-11minutes turn off and turn on again it should start. You may have to repeat these steps up to 4 times in a row to completely clear the security.
My security light stays on constant and doesn't flash like yours with out the key in it in the same truck why? With this fix my nostart problem?
GM antitheft systems are nothing but future problems waiting to happen! Has been the case for years.
Or just disconnect both battery cables and touch them together for 30 seconds and be done
I tried that before going crazy. If this problem was that simple this video wouldn’t have so many views

My truck still won’t start and no security lights but when I put it in drive hazards turn on and truck stalls
Or you go to the Chevy dealer with license and registration, if no chip the key is about $10
Then make your own video about getting bent over the service advisors desk bud.
And this drunken youtube video helped more chevy owners for free then any dealer ever would.
Wow bro i fr had my doubts that this would work. i have a 98 c1500 and replaced the vats module itself, ignition cylinder, and ignition wiring harness and still had the same problem, flashing security light it starts but dies after 2 seconds . tried this and after following all steps it fired right up after the 3rd reset thank you so much bro i was so tired of pouring money into my truck.

Got a 98 Suburban with 454 and same issue,, screw the 300 security module. Going to try this since it worked on your 98 truck.
Thank you so fucking much 🙏
Saved my life dude. Thanks for taking the time to post this. Reset 3 times and now it starts!
Thank you very much !!, this procedure worked perfectly on my Suburban 99 OBS
Just completed on my 99 surburban you are a life saver thank you so much Peace and Blessings ........... subscribing .................
Bro what do I do I’m scared
Bring it to a mechanic
Sir you are amazing you are a gentleman and a scholar I appreciate you so much I would love to send you some money
It does not work
You probably fucked it bud
@@zachnuketown I did everything the video said to do now it starts a for a couple seconds stalls out and then won't do nothing after that again

It worked hell 🎉yea. I did this on my 2004 Chevrolet suburban,and my check engine light is off now , THANKS BRUH!!!!!!!
