The only time the GM anti-theft system prevented someone from starting the vehicle, was when the owner needed to start it. Dealt with this problem monthly on my 2002 Chevy Blazer. It would routinely take 6-10 minutes for the system to re-learn the key. Needless to say, I got real good at doing this.

[@Mr76Pontiac]

I had this problem with my 2003 Pontiac Grand Am GT. Fortunately, the only time it ever really "quit" on me is when it was near home. Like, I mean, right in front of the house if I went out to do groceries, then come home, unload, then want to take off again. It was absolutely a PITA when it happened. I didn't do anything about it as after about a year or two, she succumbed to rust problems and I bought my 2011 Chev Impala, which has NOT given me any kind of security issues yet. I still own it, she still runs fine. She's been side-stepped with a 2017 Chev Malibu Hybrid, but the Impala still goes out weekly for random trips. It's become a weekend boat.

Don't know how often you do this type of work Mr. O but I got one would like to see more. As our vehicles get older, these immobilizer systems start to fail, leaving us stranded with many hundreds of dollars to be spent between towing, parts, and locksmithing.

[@johnhpalmer6098]

That is true, but remember, not everyone used an immobilizer until at least 2004. I drive a 2003 Mazda Protege 5 wagon and it has no chipped keys so it does not have the immobilizer, but the 04, first year Mazda 3 does, as did many manufacturers by then. GM, and Ford did did this security thing on some models as far back as 1988 on the Corvette and Ford by the mid 90's when they went with a new key system on cars like the Contour. Some Chryslers may have had it before 2004-05 as my mother's Dodge Stratus (I think an 04 or 05) did not have it. Later models did however.

Thanks Eric - This video was a great help! Thought about spending the $80 on a new lock/sensor assembly and the all-day time and lack of tools that I really don't have before finding your bypass video. I have a 2004 Avalanche and the wiring configuration appears a bit different but I figured it out. My voltages were 5.0 and 1.7 across the leads with switch off/on respectively. I used some basic math with your values and set my resistor to 1,236 ohms. Tested the connection and had 1.65V across the leads so I tweaked the resistance until I had 1.7V again. Worked perfect - thanks again for sharing your knowledge!

[@aarondiehl1307]

Good morning Eric, I hope you are doing well! I followed your bypass video and all seemed to go well. However, the security "feature" still persists. About an hour into driving the truck, the failure occurs. It usually starts with a radio malfunction and it dies. Then the Christmas tree of dashboard lights and gauges going offline begins. With the bypass resistor, I did notice the display cycles from Driver1/UNKNOWN DRIVER - slight difference from original problem. I'm able to clear things with a battery disconnect/reconnect with an hour delay however, the failure occurs as described above. Is it possible that the BCM is the issue? I really appreciate all that you do! Thanks again, Aaron

Love your videos. I've been struggling with the infamous "no-crank/no-start" problem on a 2001 Monte Carlo. Just when I think it's gone, it returns. The car was subject to the GM ignition switch recall a few years back and had the repair. When I pulled the ignition switch, the PASSLOCK sensor had been secured by a cable tie which had slipped, so I replaced it and added some electrical tape for good measure. Worked fine for several months, then out of the blue, the problem was back. I read somewhere that a weak battery can cause it too and since it tested as bad, I replaced it and the problem went away again for a couple of weeks, but suddenly returned. Just replaced the ignition switch housing with a Dorman from Amazon that was only $40. Found that the PASSLOCK connector seemed loose in the new one also, so I did the cable tie thing again. Car is cranking every time now, knock on wood. The sensor just clips into the ignition housing though, so I'm not sure how replacing the housing helps and I won't be surprised if it doesn't. I reused the old lock cylinder and existing keys. If it happens again, I'm going for your bypass solution.

[@parnellitube]

Did this on my 1994 Bonneville. Just read the resistance off the key, did the math, and grabbed a couple of resistors from Radio Shack. No re-learn necessary. That variable resistor is handy, now that there isn't a Radio Shack on every corner.

Good engineering there. Whenever I used a variable device like your resistor, when I got it set I would put a dab of fingernail polish on the screw and housing to hold it in place. If you ever need to adjust it again the nail polish breaks free easily.

GM engineers designed this GMC to last 5 years without a major repair. They did that so that the car would be affordable. Yet here it is running at 21-years-old. That "key recognition system" is an electronic device and yet it lasted 21 years. Do you have a cell phone that old? A TV that old? A computer that old? Right. I repeat, this is amazing.

I have a telephone that's older than this. (It's also rotary.) 😛

[@tomoakhill8825]

@@LadyAnuB Visited my childhood home in 2018, after 60 years, the wall-mounted, rotary phone was still working. But... that is my point. To buy a new-technology phone that durable today, you would have to spend thousands of dollars. To buy a car that durable is certainly possible, but it would cost several million dollars. That rotary phone was owned by the phone company, and they sent a repairman to the house to fix it at no cost to the homeowner. AT&T did not want them to need repair.

Crimps have their place, and this area is one of them. Bad place to put high heat and roast something that shouldn't be. Good job - as usual.

Always makes it look so easy.

Holy shit dude. Pro Mechanics Like Mr. O here are fkn geniuses. seriously... I wish I were this smart. I have this same problem with my ABS and BRAKE lights and they drive me insane but I just don't have the balls and in particular, the knowledge and experience to figure things out like this. I wish I was just half as smart as this fellow here.

I was a technician back in the 70s80s . I wake up most days thinking there’s not much I can’t fix and I know a lot of chit . Then I watch Eric and realize I don’t no chit always learning something. Lol remember folks if he can do no you probably can’t unless you got 35 years of experience like Eric 😂😂

[@williamwales6619]

Just another example of experience wins out. Love the commentary's.

[@brucemarkey7177]

Thanks for this video Eric! My buddy has this problem with his 97 Grand Am. So just to be sure I've got this clear. The passkey sensor on these are dying, and normally the passkey reads the resistance of the inserted (and learned key), so the bypass is to simply put a resistor across the wires to simulate a key, then learn that resistance value once, and since it'll never fluctuate, it'll always start with any key that is cut for the ignition?

[@pacificparts]

yep any key that will turn the tumbler will start the vehicle.

@@pacificparts why would you steal a gm in the first place.. ever watched ausie bathurst..all the holdens run ford parts..or they,d never win or finish..fact.. toranas, have rear drop tanks,,so you cant see the 9''diff. plus they run v8 brakes on the 6 cyls.. bartletts camaro,wanted to run disc, as they do in u.s. but wasnt allowed..he rolled it.. ford sierras, johnson, 4 laps ahead, banned,, 1989.. all european cars, merc, niss, toyo, ect, at bathurst, now,, had to de tune there engines,, to race specs.. this is why we call it a taxi race, all the fkn same.. when mustangs were first,few yrs back, raced, they won every race, so they got,''modified'', to comply..

[@RobertHancock1]

Yup. Except on the Passlock systems, the resistor is not actually in the key, it's in the ignition lock cylinder.

[@JoeCdaYT]

The quick way is take the key if it has the black pill in the middle of key and read resistance across either side of the metal contacts. Did that on a 1992 Buick Park Avenue. Had the same issue. Did help that I worked at an electronics based facility.

[@GunnyNinja]

That's passKEY. This is PassLOCK. The clue is in the name.

[@bones007able]

Seeing those internal capacitors going across the terminals on the module explains the reason these fail... caps will leak , short or open after so many years

[@thomasreid8504]

I just started having this problem today. I am so glad to have found this fix. Great job in explaining and showing !!!

[@jafo461]

Show us how to open car doors without a key and then start them. haha. Nice work as always. Cheers

[@SouthMainAuto]

oh that's easy...

Nice video, please put the link to buy those resisters. Thanks

[@buckeyejim2989]

👍👍

[@Menchaca419]

Thank you for this. Have been trying to bypass my security for about 2 months now. Thanks to this my truck is operational again, added aftermarket security and autostart while I was in there. Appreciate all the detail 💪😎

[@sirreginaldthe4th]

"As long as it's sharp enough to cut you when you slip you'll be ok" I thought this was the only way.

[@jessieharbinjr.6589]

Had this issue on a customers 94 Grand Am. The pass lock circuit went from the ignition through the cluster, and into the ignition control module. The cluster circuit board would overheat when the instrument panel backlights were on (headlights were on), cutting out the signal wire. Rebuilt the IPC and problem solved. Had to solder in a resistor onto the IPC to keep it from shorting out again. While I was in there, I replaced all the stepper motors for the gauges.
