Come along as I show you how to bypass the Passlock™ security system that GM used in their older pickups and cars. It is a really simple system similar to their older PASS-Key system. The majority of people around here don't want to fix them properly because they are rust buckets. Can't blame them I guess....

ITS 2022 YOU CAN OUT A MALE IN A MALE LOL
Sure seems like an effective, quick fix, but why not eliminate the security lock completely? Expense?
With the crimp and seal you probably have a lot of people who they don't work for and they get annoyed when everyone tells them how great they are. 😆
Could be the difference in brands.
Good video
Why do the mfrs install this crap ? Interlocks on this that & the other thing . The customer is paying for something they don't want !
Is this pass lock system on all 06 silverado pickups or just the fancy versions?
(Thanks for teaching others how to fix it wrong)….. Later when the repair fails…. Mechanic says " Well you know if you had fixed this right the first time, you wouldn't be having this problem now". Customer, says " But you're the one who fixed it!" Mechanic says, " But you couldn't afford to have it fixed right!" Customer says, "So you fixed it WRONG?" Mechanic says, " That was all you could afford!"
Hey….was Best Buy in here!😉
I used to do something like this on the Cadillacs except if it were 3 olms I went to radio shack and got a 3 olm resistance and would cut and splice it in.
Can Ford PATS II be bypassed. How about a video?
i know, but we are going to very Gingerly cut thru here… why? because we like Ginger and the Professor and Mary Anne.
If you are in the dark here, sorry… your loss.
The interesting thing really is… Robert is my Uncle.. for real.
Crimp and seal connector. Good for interior applications. Engine bay, id say sodering wires or presoder connectors are better along with shrink seal.
If this guys getting tons of water insidr his car…..he's got bigger problems lol
Heat shrinkable butt connectors are the shit my guy!
Those flush cuts will cut anything
sweet piece of work mr O
Wow Eric that is straight up Mcgeavvor sh1t. Those people in your town are blessed to have you.
Not the crimp and seal connectors again! I can’t believe you keep using those despite what all of us experts tell you. 😂. Keep doing you, Eric. Great job as always
You my friend need to invest in HP Tuners. Yes, it costs a little $ up front, but for $100 you could have disabled the Passlock in about 5 minutes w/o cutting any wires or taking anything apart. Few strokes on the keyboard & presto. Goodbye Passlock.
Edit: I have the same Snap-On flush cuts and will agree, they are amazing. Until someone borrows them, drops them and the tip breaks off after smacking the concrete. And of course the only Snap-On guy in town up and left.
Actually these are the PASS KEY II from 2003 on down then GM changed it to PASS KEY III in 2004 on up and have 32 different resistors you can use and after 2004 no pellet notch was engraved in the key shaft relocated to the head of the key. The only thing by doing this if you have full coverage insurance and you car or truck gets stolen being that the security system was altered they can deny a insurance claim for tamerpeimg with OEM anti theft equipment.
I prefer wire nuts for my connections
I’ve been using those crimp and seal butt connectors for years and have literally never had a single comeback with them, some people are just way to obsessed with wanting everyone to solder everything lol
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.
D o you have a video on how to fix the tow/haul mode button on the same model years? I have an 03 sierra tow haul mode button stopped working. It only worked when I would tilt the wheel.
….,..no use now.
Crimp and shrink are great, the regular non sealed suck anything but scotch locks
people only hate on crimps / solder when they don't know how to do it right.
“Robert is your mother’s brother!” 😂
1.28kΩ seems out of the tolerance range, the closest would be a #5 key with a 1.13kΩ nominal resistance. Would it be better to set the variable resistor to 1.13kΩ in this case, or is the problem caused by the passlock reader going out of tolerance? Wouldn't it be easier to just measure the key with an ohmmeter and make the variable resistor the same value?
PATS2 was just a carryover from VATS. There was only 15 combinations of resistances needed, the only difference is the PATS2 resistor was built into the lock cylinder vs in the key. So all you have to do is read the resistance on the 2 signal wires, and replace it with the same value.
Great video, keep them coming 👍
"The strongest lock in the world is one that nobody can open" – General Maintenance in 1999
Shoulda really blew up the interweb…….shoulda used scotch locks lmao 🤣 😂
can that be done on a 2009 ram 2500 bought from salvage yard and keys got lost trying to start engine before i pull
Gm garbage at its finest…what a joke….garbage motors…ghetto motors….you couldn't pay me to drive a chevy
Another great smart work-a-round to a problem is why we watch your channel.
Excellent job sir
Next time you get a "PASS Loc" no crank, look at the 'Starting Procedure' in the owner's manual. I once had a 2001 Malibu that gave me problems and cost alot of money at Dealership to replace ignition switch. Fix lasted about 2 weeks and then 'No Crank' and "security" light struck again!!
I towed car home and eventually dove into problem. Owners Manual gives 'Code Relearn' procedure which I used. Never had another problem after that. Dealer screwed me!!
Also, anyone that moans about crimp connectors can go pound sand. Haven't they noticed what literally all the connections in the OEM wiring harness are made with? As long as they are decent quality and crimped properly there's no issue.
I was just saying to myself “I wish Eric O would post another repair vid using crimp connectors” and low and behold! Very ASMR
Real men don’t use seam cutters, the use dull blades!
This was a very cheesy antitheft system that depended on sliding mechanical contacts in the ignition switch that were lubricated with grease. Of course when it's -30 degrees outside that grease could turn into a solid and block the contacts apart, causing a no-start. Had that on my '03 Saturn.
Of course they could have done something even worse with that part, like have the ignition switch potentially shut off while driving, disabling the airbags and killing people.. Oh wait, they did that too!
I wonder if you need a chip key after doing this trick? Thanks for sharing.
My mother’s brother is named Robert. That’s right, Bob’s my Uncle
I personally dislike scotch lock connectors use in the elements. Inside a dash I'm fine with it.
Ive done it with blazers and s10s, no need to find the resistance etc, I simply cut the wires and connect them to themselves. Leave the key on for 45 minutes with the charger hooked up to follow the relearn procedure and you now have a 0 ohm key! Ive done this 6 or so times over the years
Can always rig up a floor starter switch. lol But god I always loved a good remote start switch, when working on car's and trucks.
I figured that if you were presenting this method on the video it must have worked, but part of me was hoping something would go wrong, so I could say "Resistance is Futile!"
I had to do that to all three Grand Am's I have owned, but I also had a 97 Cavalier Z24 and no matter how hard I tried I could not get it to work.
Yet another reason to not buy GM vehicles! 😂😂😂🎃🎃🎃
ANOTHER great video!
my 1999 silverado had a problem with security light was the mother board had some bad solder joint had to have cluster rebuilt also low battery voltage could cause it as well
"Make it look like Best Buy's been here". That made me laugh.
Love the crimp and seal connectors. Been working at a GM dealership for 30 years and haven’t had problems with them. The only problem is when the parts department buys cheap ones. It happened today installing a trailer brake controller, crimped the connector and the wire pulled out when I was testing it. SMH
I have a 2001 impala with the 3400. I had the same problem. Was also having issues with the a/c not working. It was an issue with the bcm having bad soldering. Replaced bcm, (had to get programmed at dealer) and all those problems were solved.
Locks and security systems only work on honest people. By the way plumbers know all about not being able to put a male inside a male, to bad the dingle berries in San Fran. don't know! 🐹
Definitely need to do this on my 04 impala. Won't start let in sit for 10 min starts right up
Very good video . Question 2k ohm resistor by pass would work on other cars or trucks too ?
Awesome side cutter… subpar stripper. LOL
or just don't buy a GM vehicle
I bought a 6.0 Silverado used for a winter vehicle a few years back,drove it home perfectly fine parked it changed all of the brakes and lines, and it never started again I spent hours upon hours researching looking for this fix and never found a good one I could follow to get the truck to start, and here you come years later and resolve it in 10 minutes. I love and hate this video all at the same time!
"You can go get a pair of strippers or you can use what you have in your hand." 😂 Truer words have never hit the tubes of youness.
I use those sealed crimp joiners everywhere externally great weather proofing once heat shrunk
Still more secure than a 2020 Kia or Hyundai.
Hey I have the 2003 silverado and the security syatem light stays VERY DIM lite on the dash all the time even when the truck is off and key is out. Truck still starts and runs great. I had the cluster at united radio a bunch of years ago and it was off then..
Would this work for an 03 Wrangler?
Eric; some jobs you will never forget ! I have a few after 50 yrs. Here is one related to GM security ! I close the garage for 2 weeks every summer, +/- 4-5 summers age, I go in on Thursday,
. to do some paperwork.Been having “sticking “ ignition key on his 2001 Impala & no start. He puts it off! Now Towed in , his family want to go on their holiday Friday night! I check,,,needs ignition switch (in dash) No big deal, I call dealer, come pick up his key & bring to me Friday morning,,, I install,,,programme security,,,have a good holiday ! I said I would call the minute it’s done. No Prob ! Key comes @ noon,,install,,, put to programme with key, do some paperwork. Check in 10,,, no take ? Do again,, & again !? WTF Friday ! So I relearn again & stand & watch “security heartbeat relearn” Right in the middle of the hearbeat +/- 5 minutes, “ LOW WASHER” warning flashed,,,,,, disrupting relearn ! Put 2” of water in washers , relearn again,,,, bang,,, good ! That day ,,, I hate my job! What are the odds! 👍👍👍
That yellow light was flashing. Why did you not start it one more time, to show that the new connections worked?
You forgot the step where you test it right before you put the cover on so that you can definitively demonstrate that putting the cover on caused the fix to no longer work. It's a law of the universe.
This is all good given you already have the scanner and or meter, but hp tuners has gotten pretty cheap enough to be a reasonable replacement for what you just did. Plus you can do a ton of other things if you're brave/dumb enough.
Wow 😂 but you still have to have a key to turn the tumblers anyway, I guess you could just Jamba screw driver and steal it
Should have soldered those wires.
You can't put the male into the male? Hmm. I saw people doing it in CA. Seriously, that was a great tip. Those things were pita
This GM security key issue resulted in the company I work for to stop buying GM cargo vans to the tune of 500 to 600 vehicles every year
hey south main,awesome job, i recently had this happen on my 2001 towncar,tired of it,will this work on my ole ford ? commenting all the way from louisiana
Nice mr O
link to the variable resistor please
I agree with the other comment the only time that I know of that this anti-theft crap stops a vehicle from being stolen or operating happened to me and my brother after we got gas one time and then his truck wouldn't run at all would not start nothing so I wish I would have known this trick back then but thank you very much love the video
Eric mentioned that he got the 0-5000ohm potentiometer with pigtail leads from Amazon. Was anyone able to find them? Is so, could you share a link?
Connection by your press-connectors:- Why not are you not "tinning" the exposed copper with a little solder before clamping? That would protect the copper wire from oxidation and corrosion due to humidity ingress. Yes, it is another step in a convoluted process, but it is a stage that should not be omitted — REALLY! As an alternative, the two exposed ends should be twisted around each other mutually and soldered, and THEN, the heat shrink tube shrunk around them. This is an even better type of joint. Another form of joint is a mixture of soldering and compression:- a heat sleeve is put in reserve on one of the leads (usually the longer one), then your tool compression joint without a covering is put directly on the two soldered ends, then squeezed (if space allows and heat of soldering iron allows, the joint is soldered, then crimped, THEN the heat shrink tube is pulled over, and shrunk. Yes, a little of how to make a simple not-so-good job rather a bit more complicated, eh?
im scared that the Woke Mob will try to cancel you for saying '' you can`t put the male in the male ''
I fully deleted my 99 3rz Tacoma. Lots of wiring wizardry on that on. Video coming in a bit. Got a TPS fault , IAC malfunction and an injection plug repair still persistenting.
I did this to my mom's car. It was so long ago that I got the resistor from RadioShack. And that was the very last time I ever set foot inside a RadioShack, because the sales clerk was more interested in spending 20 minutes to show some idiot how to use their phone than he was in spending 1 minute to ring up my purchase. That was a "Passlock" system I think, where the resistor is inside the lock cylinder and you just leave the key ON for 10 minutes for it to relearn the new resistor value.
I didn't understand the Best Buy reference….
It is better to be pissed off , than to be pissed on
I saw someone using a "seam Ripper" on opening tape like that, I am sure your wife has one. Love you videos.
Car thieves back in the day used to pull the fuse for OnStar. Couldn't track it. After that they bring an E.c.m. and an ignition cylinder with them. Open the vehicle, pop the hood. One guy plugs in the e.c.m. in and the other guy brings the key and cylinder. Dash lit up but travels. Nowadays you steal a Chevy truck and the transmission fails. Class action law suit
Awesome thanks
I HAVE SEEN vehicles that were NOT stolen because of this system, but would have been gone had it been bypassed. More than once. I've seen more of them that were actually stolen despite this system, but it does work sometimes.
How would Scotty Kilmer do it?
All the tools you need is a good pair of diagonal pliers ,crimp pliers & cigarette lighter LOL Cheers Eric & it's a tie in the looks comp with Ray LOL.
👍👍
I'll admit it, I had to go look up what "Robert's your mother's brother" meant, today.– for those wondering it means success guaranteed. (Originally from politicians winning via nepotism)
I needed to see this video I got 2001 GMC sierra 5.3 I better buy those resistors now, just watching this mine will probably go out, lol,…thx Eric O 👍🏾
I love those connectors
In regards to crimp and seal connectors: Caterpillar corporate puts out repair instructions using these as the only allowable repairs for their wire harnesses on all of their equipment
My wife assured me I cannot have a pair of strippers.
You can put the male into the male if you use a butt connector…
