HOW TO PROGRAM A GM | CHEVY CODED | ANTI THEFT KEY | PCM Replacement | Security Blinking 

Thank you friend for your video I had with my car more than a month stopped because at the authorized workshop they told me that it was the modules and everything was a lie thank you for sharing this information, blessings I am from venezuela and here there is nothing of respite And everything is super expensive that saves me a lot of money thanks a lot

This is the only method that worked for me. Thanks man

Thanks homie! that worked! I replaced ignition assembly and had this problem. Thank God you made this video!

Life saver. Thank you, thank you, and thank you so much🙏🏼. It works.

You are my hero! Saved the day on an 2008 Saturn Outlook. Thanks for the information.

Are you saying to turn the key to on 3 times and then on the fourth try actually start the vehicle?

I am a retired GM Tech and I own a 2003 Chevy Impala with intermittent security problems. I do the relearn procedure and it usually starts after the first relearn. Sometimes I have to do it twice taking a little over 20 minutes total. This is a temporary fix for any of you who don't know. There is a part of the system that is failing and I have yet to figure out which part of it needs to be replaced. I'm not a parts changer and I like to verify what's bad. I've even tried to get answers from my local GM dealership but these are secrets they don't like to give away. I guess I will just have to take the long route and figure this out myself.

Do you turn the key to the OFF position between each of the three 10 minute intervals or just leave it in the ACC position?

Hello bro, you really save my life with this info n save lot of money too. God bless you.

Sir I tried it really worked.Thank You

thanks it worked! you sir is my hero. 🙌

I woke up one morning and out of the blue my remote start cranked engine but didn't start. Put key in ignition and same thing, cranked engine but wouldn't start. Tried this method and it worked for me.Thank you for posting this video, definitely helped. ( Not sure if it matters, but I sat in my truck the whole time with the door closed)

I own a Chevy impala 2007 and this video made my day. Thank you so much.

It also works on 06 Chevy trailblazers thank you very much for sharing

It worked. Thanks.

Work like a charm I really appreciated this video thanks again.

Did you turn the ignition over and bump start it like he did OR did you just turn the ignition to the ON position? I have to do this to a 98 seville STS tomorrow and found two sets of instructions one says to bump start it the other says just to turn it to the "ON" position...?! Thx! O_o

Thanks for posting. It solved the problem on my Chevrolet Avalanche 2002 that wont start. Thanks Johan (SWEDEN)

Thank its good video but have question my secutity light stay on. U know wy

My 2007 Rav4 wont start due to issues with the security system, is there a way to fix this problem without replacing the ECU. Would your procedure to program the ECU on the Hummer work on the 2007 Toyota Rav4. Where would you buy a used high quality ECU Thank you for the excellent video. Ragards Thank you.

Thank you so much, And this technique still works (may2021) On Pontiac g6 2008!!!

Worked! Thank you

Thanks you so much I am from Sri Lanka

Yeah tried 3 different ways to Sunday! Off comes the ignition assembly. Even tried new key as well as old key was very visibly worn!

Can u do this with the dash off or does the dash need to be on.. 2011 chevy express

I have a 2005 Chevy Malibu what does it mean when the padlock with a key pops up when trying to start the car is that the reason why it won't start.

My 02 park ave starts and runs fine but has a solid security light while driving. I'm worried one day it will not start due to this. Should i do this procedure with it or just let it go?

So, is this just the anti theft to be reprogrammed? Or will the bcm just figure everything else out itself? Aka door ajar switchs, Windows, locks ext. of course I would think you would need to reprogram fobs? Idk looks like you got more experience with them then I do. So I thought I would ask a pro :-)

I tried this, and it worked!! I have a 2004 Chevy Colorado and I replaced the ignition switch. The reason I replace the ignition switch is that it would sometimes start, and sometimes it wouldn't. I put the new switch in and it wouldn't start at all. I tried your procedure, and now it will start, whether it fixes the original problem?... only time will tell. Thanks

Could you tell me .. Will this work if you have an immobilizer and theft deterent .. Ive got a 2004 chevy aveo LS hatchback 5 speed. With immobilzer and basically if you lose ur key and need a new one will this process work if u already locked the car out by starting it with a new key not programmed and the new key is the basic key with out the key fob (door lock and alarm buttons built into key) .. Lets say i locked it out with that key which is not a immobilzer key and lock cylinder .. I then changed it out for a brand new key for immobilzer with key fob( lock buttons) .. Now i have the new key and lock cylinder in.. Its still locked out (security light is on) from the first key switch and lock cylinder i did myself... With the new lock cylinder in and new key. Can i reset it this way? Because i have tried to no avail.. At first I did this process without the immobilizer ring snapped in to where it goes on the lock cylinder it was just hang in there instead and the security light was on steady then I tried it with the immobilizer ring snapped on to the lock cylinder how it's supposed to be and tried this process and the security light was flashing this time but still the car won't start the security light won't go out if I put the old lock cylinder and key back in and did this reset process would it work on the old key since it was programmed into the immobilizer already the BCU and ECU already acknowledged that key but since it's in lockout mode I haven't tried to put the old key and lock cylinder back in do you think this process would work if I did that or what I need the scanner with the anti-security theft deterrent built in

How about for a 2015 equinox its stuck in lock mode wont turn over at all

Thank you for posting this info...it did work although after it being fixed it sat for about 2 hrs and the problem reocured...does it have to be a full 10?...also looking for more info on how to eliminate the problem w/o purchasing a new ecm?...I have a 2000 k2500 5.7 350 Thanks! Shawn

excellent video great job

Thank you ,your video helped me ,car came running to my shop and next morning did not start ,truly appreciate your efforts

Does that mean it’s programmed for good? Or you think it will mess up again?

At this point does it need to be a new key or can I reprogram the one that’s isn’t working?

Works for me. GMC CANYON 2005 4X4 5 Cylinder. Hope this repair my problem. Engine turns off while driving, when engine shut off the antilock light flashes, must wait 3 seconds to start again.

I tried to remote start my 2015 Chevy Silverado on the MyChevrolet App and then i get an error saying I must drive it first before I can remote start again. I go to my car and try to start it with the key and I get nothing. I come back in the afternoon then it starts up? WTF Why is it doing this? I thought it was the battery and I replaced the damn thing and then in 2 days it happened again. Does it put it in some disabled mode? How do I overide it? or is it something else?

I have a 2003 suburban Chevrolet and I tried it worked but it comes back the theft light stays on when driving can you please help what could it be

Will this work for 2008 cadillac cts

Thanks man from Tahiti : excellent les gars pour Hummer h2 sut

Will this work on a pt cruiser?

To sum up my last comment and to add a little detail when I bought the car it ran but the key does not fit the doors so I'm guessing it's been switched before and now the lock cylinder seized up so I switched it with one from the junkyard off a 2006 and was a base model key with just the 3D head without buttons I started the car with that it ran for a second then shut off and locked out security mode I tried this process to reset it to no avail... I then got a key and lock cylinder from dealer that has the lock button and is made for ignition with immobilizer and tried to reset it with this process to no avail... I'm not sure if that is because switching keys and trying the wrong type of key which still has the RFID chip but doesn't have the immobilizer and then now I'm trying a key with immobilizer in it with the lock buttons

ey man i need help!!!!!!!! i buy a new computer for my ford taurus 2000 and the store were i buy it say it will come program, but the anti-thef will not and it should be program by a pro. how this works and can i do it my self or u need special tools or what?

Hey Bro I have the same problem do you found out what it was after all!?

Hi will this work for 2005 rx8?

Does this work on 2013 traverse?

Hi, I have an Avalanche, I need to replace the used computer with another used computer. The car brings Limited perfomance

im a try this on my chevy sonic LT 2014 today hope it work.

Why would you need to program a key with no chip in it? Typically just leaving the truck off for 20 or so minutes will do it. But the best solution is just to clip the passlock wire and be done with it forever.

It works!!! I made it (Cadillac cts 05)

I tried its wroked in Bolero sle, thank you sir

Thank you for you help Its work for my hummer h3

my computer went out on my 2008 chevy 3500 duramax and i bought an new one and i tried this process but it is not working at the end of the process the light just stays on

Thank you men works perfect

How to do a dodge neon. My car still won't start and I try this . Thanks so much for any help from anyone.

I have reprogrammed my H3 3 times over the past year and it seems to work for awhile then it starts not wanting to start. I wait 10 min and then my H3 will start. Is there something else that I can look for?

I tried this but is not working, I saw another video saying you don't need to crank it . Im. Able to turn on the hummer just by switching the key fast

Does this work on a 2006 pontiac montana

Will this work in a Ford F-150 2010

Every morning my truck does that it's a Chevy Colorado I haven't done that program think yet because I leave the truck like that and take my other car but once I come home to turn it on and turns on I'm guessing it's the key doesn't have the original one you think it can be the key ?

Im tried doing that same procedure to my 2004 Cadillac deville and it did not work. All i did was changed out the battery and after that it did not want to start anymore. The car only cranked but did not turn on. Really lost here. Need my car for work and this security system really makes it hard to get around
