Hummer H3 Passlock Repair - How to replace sensor

How to fix the hummer h3 passlock sensor. Flashing passlock keeps you stuck for 10 minutes. Plenty of solutions on the internet from bypass the key passlock with a module but here I test our replacing the sensor.
UPDATE 2023: THIS SOLUTION WORKS. ITS BEEN FINE FOR YEARS. NEVER HAD TO WORRY ABOUT IT EVER AGAIN

[@brianleland9635]

Sorry for cursing but I CAN'T FUCKING BELIEVE THIS WORKED. 10 years I've been deal with this problem off and on with my H3. As of the start of the cold season, I felt like I had 20% chance of my car starting in one shot. I love this car but I was about to set it on fire. I switched it out today and so far it has started up right away, every time. I feel like the old girl is brand new again. I'm actually happy driving it, now knowing I don't have to fear shutting off the engine. THANK YOU!

Hey Brian can you give an update?

[@smithboysmurf9353]

Yes update please

[@jagijonee4155]

Going to change mine right now ! 2006 Hummer h3

[@jagijonee4155]

Thank you for posting this !! I have a 2006 Hummer h3 that does this all the time now ! I’ve done it all…. I’ve replaced oxygen sensors , fuel pump, fuel injectors , alternator , you name it … battery .. replaced the terminals and it still does this …. Ordered the part and going to replace the sensor myself .

[@jagijonee4155]

Thank you so much for this video !!!! I replaced mine January 28 2024 and haven’t had the issue since … mine was happening almost everyday . I appreciate you thank you

[@Chadman03elantra]

This issue caused my family a bunch of trouble on a trip a few years ago from Ohio to S Carolina. We were clear down in N Carolina and stopped for a break and H3 would not start up. We tried quite a few times to start (obviously not knowing to wait the 10 mins) with no start. Called a mobile mechanic who was close by and he said it was fuel pump. So we had to have it towed to local dealer and go find a car to rent (just barely got one before closing time). So dealer calls me next day and said started right up for them no problems. We went ahead and had the pump replaced for over $1000 because we didn't want to be stranded when we came back through to pick it up at the end of the week. We picked it up and it started and we drove home ok. But then it did the same thing again in a few months. That's when I did so research and found out about the passlock issues. Can't believe the dealer didn't even mention this as a possible problem before gouging me for a fuel pump.

[@jboeckel]

I looked at a lot of information before I tried this but I wanted you to know that your video was the most helpful! The pass lock didn't want to come off of the new part but your video gave insight on how to do it, thank you very much for taking the time to post it! 2004 GMC canyon, theft deterrent light started to come on randomly the past few weeks. It stranded me once two nights ago, ordered D1462G off of Amazon and put it in tonight. I had to relearn like yours (I read somewhere that they have a few with different values sometimes you get lucky) seems fixed for now. I really appreciate it.

[@devil2070]

Have you had any issues

[@d.scottblacktopchanel5699]

How did you get the new passlock sensor out? Mine is stuck

[@mannyosr]

Thank you, just fixed my 2006 hummer, it was getting worse every time , God bless you 👍🙏

[@acm1pt374]

I did the wrong research and thought it would involve a lot more. So much time wasted and frustration. Thank you so much for this!!! Mine didn't start until the 4th time. So it timed out 3 times. Seems to be working perfectly now!

[@beastmode00714]

Thanks! Worked great. 2006 Hummer H3 manual transmission (different part number). If you look at the contacts on the used sensor, the second contact from the left is burnt. The circuit burns out. Same on all the failed sensors which are a common problem. Easy fix !!!

[@nanogear164]

It works really well!!! Change mine and now all is good

[@11jsum]

Awesome video!! Worked for a 2007 chevy Colorado Z71

[@lukehale88]

Thanks Shorty! My sons Hummer H3 had the same problem. I ended up doing the programming part 4 times. I think that’s due to I didn’t wait long enough the first time.

[@tonycarver2745]

doing ours today. will et you know how it works. thanks for the completeness(sp) of the vid. subing as we speak.as of NOW jobs done, so far all good. only thing we struggled a bit with was removing the sensor from the switch. fumbled around a bit until we saw the little thing a ma jig inside to remove. other than that we followed your advice and it's all good thx again for the help.

[@graywolfpictures7]

Still a problem in 2019! Couldn’t find any fixes anywhere, but instead of replacing the whole sensor I still removed it, used canned air and cleaned the whole sensor assembly with electrical cleaner and tools brush and works great! No need for new part

[@shadoa25]

I realized over the years that most of my problems with my H3 was dirt! Rough idle: Throttle and map sensor dirty. 4x4 problem: unconnect the module and clean the connectors Dash went haywire: check ecm in the firewall (dirty as "bip*). Cleaned the connectors and checked the pins. Lol simple solutions

[@Mike-vw4wb]

works like a charm, thanks

[@Dollarrunner]

Hello, great movie with gret instructions. Parts are ordered, so hopefully in a few days the problem will pass away here. 👍 I have one other question: how can I change from miles to km's? I have searched and tried on multiple ways but I didn'r succeed so far..

[@peterl3042]

Great video Shorty! Thanks for taking the time to figure this out and post instructions - made it super easy. I'm wondering, however, if anyone else had a problem getting the new sensor recognized by their truck? I bought a new AC Delco cylinder/sensor, swapped just the sensor, and followed the relearn procedure .... multiple times. The passlock light never flashed, never went out. Just no crank, no start and steady, not flashing light, no matter how long I left my key in the on position. I even tried disconnecting the battery leads for 30 minutes before trying the learning procedure, but same result. I thought maybe I had damaged a computer somewhere, so I put the old sensor back it and it started right away, and the passlock light went out. What am I doing wrong? Any help appreciated!

[@roostercogburn3771]

There's a lot of info down below! In an hour or 2 you ought to have read some good ideas. Or go to the Duck and type in "Re-learn the PassLock Sensor". Or maybe some creative idea!

[@bckr1532]

Worked for me 2006 gmc canyon started showing pass lock failing this past year. Three step relearn worked first time around with a non acdelco Amazon part 👍

[@anastasiam64]

I just ordered the part as well hopefully it works for mine. However my issue is when you turn the key the engine does not turn over until it reset. I have seen other vids state that the engine turns over but will not start until it resets.

[@leviwalker7761]

Thank you for the video! I'm relieved to say that because of you, I'm another success story in this method of 'the fix'. For others out there, my experience took 40 minutes of waiting, and on the first 3 times my engine did not turn over (and I had little of hope of success on the 4th attempt to start, but it did!). Thanks again!

[@roostercogburn3771]

We've been working on figuring out what is the starting problem, since 2017. The problem was part time and the shop can't find a problem when it aint showing up. It did start every time for months, after I changed the water pump! Mine is a 2006 Canyon with the odd-ball 5 banger engine. Since we finally figured out the actual starting problem, others want me to replace the whole switch. And want me to take the whole steering wheel off. Along with buying the whole switch, when it aint needed! I've been unable to find just a sensor on the computer. I did find it at an auto-parts store, for $100. On the radio show, I told them that my truck's security system is so good, that it won't even let the owner steal it. Today is Memorial Day, 29 May 2023.

I want to add that I replaced the passlock housing (not the key cylinder) - this did fix the problem - BUT I also needed a new key. It seems my problem was exasperated by a worn key too. The key is NOT chipped - it is just a plan key, so only $10-15 to replace. I had a 2009 GMC Canyon.

[@jve536]

No updates on this one ? Did it fix the problem ?

[@mikeb5607]

When you reinstall the new sensor back into the housing ... does the key need to be in the run or off position?

[@chemicallyfreenolye5462]

Thanks, this worked for my 2007 isuzu i290 (chevy Colorado) i had to do 4 relearns. now my truck can be driven after yrs of sitting in the driveway idle. #ihateGMproducts

[@juanparral7420]

hello, I have the same problem, but the blocking symbol remains fixed, I changed the sensor piece and on the recommendation of the electrician a resistance was placed to fool the blocking system and it has not been possible to solve it, try the 3 cycles 10 minutes, but only in the last one I try to start it, I don't know if it will be important in each cycle to try to start it, please your help with something that you can guide me I would appreciate it very much I have stopped my truck for 5 months trying everything

[@icaanul]

For anyone that may not want to fork out the money or can't wait(need to get to work), there's a white w/ blue wire cut that fixes it. Search for it online. Don't just start chopping at the white w/ blue wires. There are caveats but if you need to get it fixed quickly and can't wait/get parts, it's a free option.

[@darelc1356]

I’d like info on this please

How does solenoid come out if New part...? Unscrewed but won't come off of part...? Thanks

[@KevlarSix]

I recently replaced mine but it started nicely. No pass lock challenge. I wonder why?

[@NoFlightZone]

Will the Parking break need to be attached for this procedure to be done?

[@FishSticks]

No it does not. The top screw is really tricky to get to. Whole process of installment took 10 mins then the 30 min start up process.

[@coyotesnper]

Did this on mine, however it would not turn over the 3 times. I did everything the same just Turning the key to engage the starter would not turn the engine over. And on the 3rd try it started up.

I have a 2005 GMC Canyon 103558 miles. mine did the same thing what everyone on you tube is not telling you is you have to be in the vehicle with windows up/ doors shut not locked and this will work, I don't know how long of a fix this is but for me it took 4 tries, but it did work.

[@savannahmccullough6779]

Has it locked up since? What brand part did you use?

Can I use this same piece for 2008

[@icaanul]

H3, Canyon, and Colorados have quite a bit of interchangeable parts. 2004-2012 GM kept installing the same turds.

How to remove the sensor from the new part?

[@peterl3042]

If the sensor doesn't pull straight off, just reach into the key cylinder with a screw driver and rotate the mechanism to release the passlock sensor

[@regboss6237]

You get the sensor FELETED from the ECM via the PCM from anyone that does engine tuning or from a GM dealership, it only takes a few mins, its a permanent fix!

[@THECDG999]

FELETED or Deleted ?..so, all I need to do is to take it to a shop and ask the mechanic to plug the computer and delete the sensor right?

[@DAMOCLES85]

Following...

So it only took two times

Get an aftermarket remote starter it works every time

[@richanzik5140]

Passlock stops my hummer from starting when I use my aftermarket remote starter

[@Quattro4k82]

That's not true. I have a compustar t12 remote start and it tells the unit to not fire because the sensor is bad.

[@friedgizzard]

Definitely not a true statement. 2 hummers, 2 autostarts, 2 passlock issues.

[@Jtrivett79]

3 years no problem starting again. The truck pass lock ( that’s in the column ran through the ignition ) that there is a problem with security, and cuts off the fuel to start the truck. Which remote start bypasses this. If you try to start the truck and it won’t start simply hold the gas pedal to the floor and it will start. Not sure how or why other guys are having problems. Maybe it’s simply the installer. Mine wouldn’t start almost every single day then I installed remote starter and never ever failed again so...

[@slademusic6175]

Everytime I fill mine up it does it so Injust leave it on lol

[@articiahughes8283]

What has been working for me is turning on the key in the on position before starting for 10 seconds (I.e wait until the the radio comes all the way on so you can here the music, the a/c settles, the engine light and car theft light is on the dash on the dashboard only and then finally you should here like a little poof or air release or whining) then before I crank the truck I push the brake pedal all the way to the floor as hard as I can and then try to start the truck. The truck cranks on with no problem. ( tell me if it works for you)

[@FishSticks]

Don’t hire someone to do it. It’s very simple.
