Got an 02 Chevy Tahoe 5.3L. This happened years ago and I bypassed and reprogrammed. Took me over an hour and a half. This just happened at the gas station again, I tried what you did and it worked! Thanx so much! Commenting from the gas station parking lot now!😁
thank you for this video from the bottom of my heart! Just save me and my wife and my six kids on a road trip, worked like a charm. Thank you thank you thank you
I researched this problem for my husband because he pulled the part and it was not showing any burns on the board. Your quick fix solved the problem. Thank you so much👌👌
Let me tell y'all what we got here.. a God dam genius!!!!! 4 days up and down the electric road and the gasoline expressway no no avail! Plugs wires... (Needed it) nothing... Then this fine gentleman and his big brain saved the day!! Thank you bro!! Better than the wizard of oz!! There's no place like your channel 😂!! Ty man!!!
Al The batterey in my 1999 Astrovan, discharged and six months later I put a new battery in! I turned the key on this previously well running machine and it started for 3 seconds and died! Over and over again and same result! I tried dozens of things after reading articles and there was no success. Last evening I ran across your video and thought, "what the heck, try one more". I did what you suggest and that Astrovan came to life like the old days and is just purring! I cannot thank you enough!
Awesome , cant believe how easy that was recently got a 98 GMC 1500 that hasn"t cranked in three years after watching other videos I found yours. SO simple i"m still in shock it works. Thank you
It Worked, thanks so much. So basically its just resetting the Vats(vehicle anti theft system) which kills the injectors after start. Just wanted to point out, you should disconnect your negative terminal, as it is safer, if your wrench contacts any metal in the area it could lead to direct short with 800 amps, blow the battery up or blow holes in tubing or whatever.
This is my first comment about a youtube video, I've been struggling with my 98 C2500 Cheyenne and the passlock system I tried all kinds of bypass tricks and none worked and laughed when I watched your video. Then on late last sunday night just when i was about to order a complete new passlock , said what the heck give it a try. tap 3 times hooked it back up and the SOB started after 3 months of working on it and letting others try. Thank You friend, The Beast is back on the road!
WoW!! That trick worked like a Champ! I was working on the A/C and disconnected the neg Battery cable. Then when I put things back together it would not stay running. Your trick fixed it first try. Thank you very much for posting this.
You're my f'n HERO!!! 98 Silverado, tried EVERYTHING. I'm embarrassed admitting what I tried. 3 touches, pause, reconnect. Started right up! Thank you Xs a million!!!
glad to see this video, ive tried explaining the system to my son when he drives my 99 suburban but like most of the newer generation he knows more than i do. gm tells you if that little icon is on in the upper right corner then turn your key off for a second or two then to on and leave it in the on position until that light goes off, then its okay to start. i guess they get triggered some way at times. never saw this trick before but it makes sense to me. with this beast holding 44 gal of fuel and lots of miles the fuel pump won't always fire it up quickly, so i'm assuming when it dies or fails to start right away the anti theft is triggered.
Just changed my battery and this caused my security system to kick in for some reason. Truck wouldn’t start. This trick legit works. Thanks for the tip.
Wow!!! Unbelievable, it works, thank you so much for posting this video, it really helps, last 3 days security light was on, and today truck start for 3 seconds, after doing same way you did, truck came on, and now security light is off, 🙏🙏
Hey there, works great! I just watched the video of the kid that put the tooth pick in the wiring harness that goes into the top of the ignition in order to tighten the connection and I haven't had the security light come on once since.
I installed a new lock cylinder in my 1998 Chevy K1500, wouldn’t start and security light on. I did this procedure, worked. I’d buy you a beer too, well done!
I have a 1999 GMC Yukon. it would start and then shut off ,start and shut off.. I tried this trick of disconnecting the positive cable and tapping it 3 times, didn't think it was going to work, but it started! thank you so much!
Hey bro just found this now, I have a 99 Tahoe that just did this and I panicked, I tried what you said and it worked! Thank you for posting this video and saving me a migraine
Just wanted to thank you for posting this video. My husband went right out after watching and I can hear my suburban running for the first time in a week.
Dude thanks for this video dude I've been working on my Suburban for almost a year-and-a-half now could not figure it out I change the fuel pump fuel filter the caps and rotors and I just simply did that and it worked thanks man
Thank for this info. I put alot of new parts on my truck and it wouldn't start. I gave up and get ready to shoot my truck and blow it up until I watch this video. Now my is running like new! Of course it got 80% new parts on it. Thank buddy.
Thanks...for the easy video fix, I have spent a bunch of money and a week with out my 1999 Suburban and it still did solve the problem....But you did....Blessings Brother.
This worked perfectly! thank you! side note: you do have to hit the button to turn the dome lights on... the first time i tried it, i didnt hit the dome light. it didnt work. Then i hit the dome light on and did the procedure again....started like normal!!!
What in the freaking hell is that about? I was at my wits end with my car not staying running and then i see this and its running again. Thank you so much for posting this video.
Thanks for this video. My husband changed the battery on his remote control and pushed the button to lock the truck and it wouldn't start. He thought it was the starter, but I was searching through some videos and I stumbled on to yours. Thanks a million. Bless your heart for sharing this trick with us. The suburban started really fast after your trick.
IF the engine cranks, but only runs for a second: Turn the key ON/OFF three times. (not run) Wait ten mins or so with the key ON, until the security light goes off. Now it will start. Te ECM just has to relearn the resistor value in the IGN wiring harness. It happens to my truck once a year.
I wish it was once a year for me. I put in a refurbished module in my 99 Tahoe, stopped doing it and then just started doing it again. Almost every day now, usually when I'm trying leave for work does it like doing it.
OK. My Tahoe has been doing wonky things for a few days-- resetting its clock or locking the doors and turning on the security dash light-- when I turn the key in the ignition, but not starting. This little trick fixed it. That's a big deal because I'm traveling without my husband and am clueless about cars newer than 1968😂. He sent me the video.
I have a 99 Tahoe and I appreciate your tip. For a minute I thought that I had the only gas gauge needle that bounced around when you turned the key on. Any chance of having another look at the consol that you have in your unit as I would like to fabricate something similar?
Thanks again! I always forget the stupid procedure and my 99 Burb sits for a couple or more months at a time before I use it, leaving the battery dead and this stupid security code coming on and it won't stay running when I jump it...
I've thought of another option taking my 1997 GMC C 3500 7.4 to a priest and having it exercised. Beautiful machine.. worth every penny of maintenance.. but I wonder how much that might set me back?
I just noticed my security light stays on. No issues with starting and running, but had me concerned. Checked TH-cam and this came up. I will keep this in mind if anything develops. In fact, I wrote this on a card as well as others who commented on other ways to fix, just in case my phone goes out and the middle of nowhere. Thanks.
Damned to Help if I know why but I followed the vid several times after leaving battery disconnected over night. It now runs fine! I think it was the Pixy Dust my wife sprinkled on the car!
Mine won’t start at all, doesn’t turn over. Hear some noise from the starter I think when I turn the key over to start it and that’s it. Seems to be plenty of juice in the battery too? I had 2 positive cables that stumped me seeing that. I’m use to just 1 positive cables from battery to starter. Where this other positive cable go to? Goes across the radiator to drivers side and back towards the firewall under some fuse boxes I think? Haven’t found the other end of the cable yet? Considering replacing the cable thinking that might be the problem. Now that I heard your comment on this issue, think I may have to give that a try too! Irritating part, is I have a Ford that lost all power inside the cab as I was driving the truck and now it won’t turn over like the battery dead. Accept battery fine.now I got 2 trucks down
Iv'e had my 96 GMC for 20 years I didn't know it had security ! I'm getting ready to change the ignition module and ignition lock cylinder will this effect the security system ?
i already did ....then my tahoe did it again and this trick worked .....gonna take this crap out of this truck...cause after awhile this wont work it will keep doing it.
I have to try this one... My 99 Suburban only cranks but won't start; basically died in the driveway because it was not used. I have change so many things: Cam and Crank sensors, fuel pump, fuel filter, injector spider, spark plugs and cables, relays, distributor cap, rotor... At first, i changed the crankshaft sensor and it started, until it came a point that the crankshaft sensor was not the issue. I guess it was never a problem due to the sensor and now that i know better, by checking spark and rpm gauge movement it was enough to discard that as a problem. I have been having everything: compression, spark, fuel pressure, and a charge battery and the clue still out there. And the other day, after started after I change the spider. My guess it started because there were lot of carburetor cleaner in the chamber when I cleaned the area while changing the spider. I will try this, what the heck.
I had the security light issue (and still do) but my main concern was just getting the car started and back to my house to work on it. I might try your method of tapping the terminal thrice later. HOWEVER-- after doing a couple of other experiments with you tube ideas on this process, I was in the process of loosening the battery terminal when the thought crossed my mind to make sure both terminals were tightened properly to begin with. So I tightened them both up and my truck fired up immediately. I have a 2004 Trail Blazer but to your credit-- this did inadvertently lead me to the cause of my starting problem it appears -- so thanks for that. I only share this information with others in case they have not tried making sure they had good tight battery terminal connections first to see if the vehicle will start up. LIke I said-- when time allows, I may try your terminal tapping method to see if that gets rid of the security warning light (mine does not flash). I have a feeling that the light started coming on as my terminal connection vibrated looser and looser. Then it failed and shut me down from starting.
I recently replaced the fuel pump and replaced the cap and rotor. The truck runs. But the security light is on. Would replacing those things cause the light to come on?
Just turn the key to the on position wait about 10-15 mins the security light shuts off try cranking it then turn it off then on it will fire up . Just worked for me after 3 years of it just sitting there
Hope this works on my 97 GMC Sierra C 3500 pickup truck Dually.. if need be. I changed all my sensors and everything distributor computer.. ECM supplier said security light was burned out behind the dash maybe nobody seems to be sure. I sent to mechanic Burbank California after two weeks finally got to it and charge $1,200. I managed to drive it out of there he did not change the key as I suggested I had a new one in vehicle. I lost. And just bought another. This is automatic vehicle not manual shift.. key assembly has syndrome you know won't even go to auxiliary position anymore have to wiggle and pray to get ignition turned on and then into crank you know that little broken part inside.. Started sticking on crank I've had to quickly turn off to try again. I figured current switch is sure to fail completely... dealer doesn't look at these trucks anymore they have been discontinued. Only the same shop that sent me out with check engine light going on periodically will work on my truck. It did pass the smog check however with incredible numbers.. in Hollywood California. All mechanics steer away from this truck some say it's too heavy. They're all crazy Maybe. I wonder if check engine light may be associated with bad key cylinder it has been on for a while now it just turned off after I bought the new key set today I kind of wiggled and played with the old stiff assembly. Check engine light went out.
been turning wrenches for 40 years and I've never seen that trick I just can't believe it and it works like a champ!!!thanks again

I have a '95 Cheyenne I also call the "BEAST" ! 5.7L with super 44 Flowmaster muffler...

Tried it out and ti worked. No more waiting for 30 minutes to do it the other way. Thanks.
lightly tap starter, wait 10 minutes, turn off key. Rinse and repeat 2 times. Standard GMC procedure for resetting security system.
Thank you so much for this vid it helped get our Tahoe going.
This worked perfectly! thank you! side note: you do have to hit the button to turn the dome lights on... the first time i tried it, i didnt hit the dome light. it didnt work. Then i hit the dome light on and did the procedure again....started like normal!!!

Man, I will try, if my truck running, I will give you free a nice truck
Repeatman ur awesome thank you for this video hell ill buy you 2 beers 🍻 🤣
Will this work on the negative battery post instead?

thanks for that information but, how do you fix the problem for good
Fuse is good at dome light ,#3 fuse but no continuity on contacts. Does that matter?
What about the hazard and liscense plate lights still flickering even though security system is off
yes but how do you disconnect the security kill switch permanently??have a 99 suburban
I wish that worked for my ex's truck I'll try it again
I got mine started and it’s idling but the security light is still on.. Thank you
This actually worked on a cold ass day 🤣🤣🤣 thanks for saving me
THANK YOU MY GOOD SIR
I have tried this 3 times now, security light still flashes, will not start, but if I wait about 30 minutes it will start, do you have any suggestions
thanks brother!!
Just turn the key to the on position wait about 10-15 mins the security light shuts off try cranking it then turn it off then on it will fire up . Just worked for me after 3 years of it just sitting there
