Passlock System

Going to try the resistor method tomorrow...

Gotta buy a soldering gun and ohm reader though

What?

Just cut the yellow wire, and butt-splice in longer wires with a toggle. No soldering or resistors needed.

It works - Guaranteed.

Scared of dead battery? That's a total pant-load and a dealer and ignorant person scare tactic. Nothing more. If your battery dies, so what. Flip your toggle back "ON" and install a new battery. If "Security" light in dash is flashing, leave key on for 10-15 minutes and restart car. Then turn OFF toggle and leave it off. "Security" light comes back on and your problems stay GONE.

Feel that you need remote start or an aftermarket alarm or your other keyless crap to still function?

Check 'em out for all your work-around needs. They are pros and know what they are doing.

As for me, I just toggled that worthless Passlock sh*t out and my problems are gone. No need for any of the other keyless crap anyhow, no matter how "convenient" it may have been. I'm not wasting another dime on this nonsense. Just need a car that runs and drives daily, hassle-free.

For many of us "Average Joe's" out there, it's much more convenient to keep our money, and to NOT be stranded -ever - because our car's won't start, all due to some defective garbage electronic technology that a LOSER manufacturer (GM ) won't admit to fault nor will they fix.

Peace out, cub scout!

With resistor, no security light.

Ah, good point... I wasn't thinking about that.

I suppose that keeping the light out would be semi-important if you were planning to sell your car, to keep from "scaring off" people.

Not to mention, idiot lights that are constantly on in the dash can be pretty annoying to some people. Personally, I choose to ignore them when I know their purpose for being lit is "meaningless".

Hi all,

I had the usual passlock issue where it would prevent me from starting the car but over a year and a half ago it broke altogether and since then the 'theft lock' light is on constantly but the car has not once locked me out. It's been great in that respect but I'm worried about some upcoming work I need to do (gaskets of course) where I may have to unhook the battery. If my passlock system is broken will my car start at all if I disconnect the battery?

[Turbo_Diesel]

Newbu... Honestly, it really shouldn't matter. The fact that the light is on steady, merely means that the system is inoperative. If it were blinking, then you'd have an issue, because then the car wouldn't start until the passlock system was reset.

Gotta be honest, never heard of a Passlock system actually "breaking" on its own to where the car will still start. I suppose it's certainly possible though. Perhaps you had it serviced at some point, and they eliminated your Passlock for you by snipping the yellow wire and you weren't even aware of it? It's certainly a possibility.

Anyhow... if it would make you feel better, you can get one of those 12v cigarrette lighter plugs that are made for "saving" your radio presets and whatnot. Although many modern cars will save radio presets when the battery is disconnected, there are also many that don't. (That's why that handy-dandy "tool" was invented and marketed.) Many auto parts stores carry them, or you can always just make your own. You plug the one end into your cig. lighter port and the other end has alligator clamps for connecting to another remote 12v source. Naturally, you do this BEFORE you disconnect your battery under the hood.

You can use another 12v battery, or a 12v battery charger to achieve your 12v auxillary power source. Basically, you are "backfeeding" your electrical system with your cigarette lighter port, thereby keeping most of your electrical system powered up.

Not sure why you would be disconnecting your battery to do engine gaskets though. If you are doing what I think you are doing (blown intake manifold gaskets are a very common problem on GM's 3.1L & 3.4L V-6's.), there is no real reason to have to disconnect your battery.

But, like I said before... I don't believe disconnecting your battery will cause you any kind of problems anyhow. It certainly shouldn't!

Well, good luck bro, and have fun with those gaskets!

[Newbu]

Hi again folks,

This is a follow up from my above post. I did the gasket change as I planned and the first thing we did was unhook and re-hook the battery to check if it would start again. Luckily it did, so we proceeded with the work from there. Now that I know it's broken but with no real negative consequence, I have no intention of replacing the key cylinder just for it to lock me out again down the road sometime.

And by the way, the reason I had to unhook the battery is because I also changed the radiator hoses at the same time and one of them runs under the battery support. Would have been very hard to get to if we hadn't.

Thanks for the reply Turbo

I have just done the "Resistor" method of disabling the passlock on my 2003 Grand Am.

I used a 2.2k 1/4 watt resistor (DIDN'T check the resistance of the passlock and try and match it with a resistor), installed as describe on forums, (yellow wire from BCM to resistor then spliced onto black wire from BCM) then did the reset code thing (10 min with ign to ON).

It worked! now no passlock problems OR warning light.

I had same problem with a 1996 monte carlo with the VATS type security (one with a "pellet" in the key). That took a very long time to disable compared to this fix.

Should this "cut the yellow wire" system work on a 2007 Malibu?

Not if the key has a + or + in a circle near the plastic end.

[chrisryan93]

please help i was woundering if a remote start will bypass all the code shit we have been trying for 2 days to get my 2002 malibu started after changing altinator.HELP PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!

[chrisryan93]

we cant keep the car running long enough to cut the yellow wire can we do it with out it running.urgent!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[chrisryan93]

i have done this be for three years ago my car wouldn't start so i had towed in we was told it was the fuel filter then he said it was the starter we had inc. then and told him to fix it so he did then told us it would proudly would happen again that he fixes that problem allot.well the inc.we got through the bank told us that part of the starter wasn't covered.we payed 582.00 to get that done .now here we go again.i was on my way to work two days after Christmas and my half way there my lights dimmed and my heater went down.then it al came backup again and it felt like it wasn't getting any gas and it staled in the middle of the road of course.i had to Walk to a department store to call a tow to get it home my hubby replaced the alternator thats it then try ed to start it .it wouldn't start.i called Chevy they keep trying to get me to two it in so they could reprogram it they said because we fixed it ourself it thinks its been stolen.it took me awhile to get the 15 min proses to start it out of them.now my batterie went dead doing that so we took that in to get it checked .it checked out fine orally said there is nothing wrong with our batterie and they charged it in 10 min.we came home and did the richiwall and it would start and stall every time.it wont stay started long enough for us to cut the yellow wire .don't now what to do.like i said right after Christmas so brook cant stand it .i wish i had the money to take Chevy down but of course we live week too week.the rich don't ask questions they just fix it so we r stuck with the problem.i just wont my car back and don't have the money to let them do it .thanks for listening sorry so long of a letter.

[ShadeTreeJack]

just wondering of you have any more luck since your last reply. I had success twice last year with the "key on, wait 10+ miniutes" process.

Hello all, this is my first post here, but I have been reading this trail and had a question.

I have been having the anti-theft flashing light and wont start issue. I cleaned the key and it worked, but I figured I would bypass it now and be done with it. So I snipped the yellow wire and measured the resistance from the yellow wire (ignition side) to the stripped black wire. At first I got 100 ohms so I soldered in a resistor from the yellow wire (BCM side) to the stripped black wire. Car starts no problem, but the anti-theft light is on when the car is running.

I read on here that if the resistor isn't correct it might cause the anti-theft light. So I measured again same way as above with the car in Reverse so it would not start and I get values ranging from 1100 to 2000 ohms. I tried putting in a 1150 ohm and still the light won't go off. Same with a 2200 ohm.

Does anyone have any ideas?
