How To Fix Theft Passlock System On GM Cars - Chevy Malibu




What do you think about this video?

wagslick: Yup. I'm no mechanic. Try it at your own risk. My car was running when I did the work. 

greg james: This guy is great, the real deal, it's been 3 years with no problems! Just have to remember to flip the toggle when you have disconnected the battery. When you restart wait 2 min. then toggle back. A couple pieces of electric tape over the always lit when on thief system light. less annoying. cheers 1999 Malibu, runs great (still)

jessica daniels: You're a rock star man! This happens to our 2003 Malibu a lot! The thing is, it used to work , putting the key in accessory for 10 minutes. It would start. NOW, it takes 3, 4 times before it will start! That's 40 minutes being stranded somewhere ! Plus the dummy light (anti theft system) doesn't blink in accessory anymore. The light now stays on, not blinking. Any idea? If you could help, I would greatly appreciate it! Have a beautiful weekend!

Rajagopal Appavu: My question: My Chevy Malibu Randomly stalls, Because of theft pass lock system? please let me know. Thanks

Young Papa: How to Fix Theft Passlock System on GM Cars - Chevy Malibu

Edgar Godoy: I did the whole process with the vehicle not on is there going to be a problem? 

tripletsontherun: Wagslick are you still out there? I am terrified to touch wires while my car is running. So just to confirm. I leave the battery attached. Actually start the car (not just to the on position right), then take off the frame and move around inside to cut the wire and install the switch. I am fearful of electricity and couldn't hear your car running in the video so I wanted to make sure I got it all right before my kids find me torched in the driveway :-)

Justin Webb: That happened to my mom on hers and she got charged 2000 dollars for a new computer this is way cheaper

Ob Fuscated: There are multiple causes of Passlock problems. The resistor trick bypasses problems related to the key/lock. The modules such as Baker Electronix spoof the signal to the PCM from the BCM, which is cheaper by far than a BCM or fighting with a difficult system. Passlock is commonly disabled with a tune in the PCM. Resistor is cheaper than module is cheaper than a tune.

Edgar Godoy: I did the whole process with the vehicle not on is there going to be a problem? 

matt w: I just detach the battery and reconnect it. The system will reset and I usually won't have an issue again for 6 months to a year. I then just do the same thing again. Chevy usually make good vehicles but they really screwed up with these security systems. I'm sure they've learned from it. 

JesusLivesandRules: I saw someone else do this with the cigarette lighter...same concept as the toggle but you have to push in the cigarette lighter in order to start the car.

Nala James: i just did my grand am yesterday...it was sitting for 2 days...cause of this stupid issue....I did mine a little different from yours, I used a resistor instead...had in started in 1/2 hr.....its disable for life.....

DocZ: "Edward S 4 months ago you can start the car through the radio you have to press and hold the #3 and #5 then press the brake padal down all the way then press the power button on the radio and press the button on the shifter that starts the car in case its an emergency and you have to press and hold the #3 and #5 and Power and the button on the shifter all at the same time while pressing the brake" Besides your HORRIBLE spelling and second grade grammar skills, your pointless comment (like in the other threads you have replied to) shows that you are another fine product of a top notch education system! Eddie, THINK before you respond to a technical thread this way you can avoid looking like a dope. Cheers. Great video Wag, thanks.

blackroses: My 01 grand am has same prob . Get rid of it . never is fixed. 

peady knight: i brought 02 impala i thank this is tha problem

Glenn Hunter: Can i put a touch screen raideo in the 2003 chevy malibu and how many inches is the raideo

Kent Peterson: I have a 2005 that dose this. Last time it did this the 10 minute thing did not work. I had my neighbor replace the switch. Bad thing about the anti lock what if there where hoodlum after me and I started the car only to get lock. I wont have 10 minutes. doubt i'd have 10 seconds for them to break into my car and kill me.

newton3010: Update....I took a look at the ignition and it looked like someone had done this to my car before. the yellow wire was already spliced and had a larger wire connected as opposed to a switch...i removed the wire and tried to start the car it cranked but would not stay started...replacing the wire and trying again. same issue..... connecting/disconnecting this wire had no effect on my car...........still researching....

brian o'conner: Will this work on a 97 

MICHAEL ALLEN: Hi,Cool video ..Does the toggle switch have to be any certain resistance?What can you tell me about ...If The car wont start...? Thanks Mike

Kelly Gish: See what I mean... These malibu are junk

newton3010: Been researching this due to having issues with my 2001 Malibu. Just thought I'd offer what I have learned as well as get some info. First it was intermittently not starting, no crank nothing...i do the wait for light to go out method as shown in another video and it would work. but recently it changed to now it will crank, but shuts off shortly after starting, wont stay started. there are two sides to this system, but the video doesn't specify what this solution is for. What I have been able to find is that for no crank at all , use the wait for light method. (turn to on, wait for AT light to go out. turn off wait 30 seconds, start car) this is the result of either battery or electrical system prob. The car thinks the battery was disconnected. For start but not stay started. This is an issue with the key not being recognized properly. On mine i believe its due to a bad ignition or key (its very worn). For this you use this method outlined in the video but you need to make sure the first phase of the security system is passed by doing the wait method. he starts the car to pass phase one. this i believe can be done when you have the car starts but not stay started problem...not the no crank issue...i will be doing this tomorrow as i have the start but not stay started/ignition/key issue to see if it helps. i will post update on my progress...

Mike Reeves: mike reeves

wakawu: So this isn't really a 'fix' this is just a get around to it.. you would have to bypass the sensor or resistor in the ignition cylinder (passlock) and do the relearn procedure. The way it shows in this video will cause the security light to come on

Joshua Starcher: I have an 98' model of the same vehicle. . I feel sometimes insecure leaving it outside (this is just sometimes.) Alone and someone braking in and stealing it. Please figure out what your doing man.

Miracle Bond: Thanks Wag.. appreciate all your help. God Bless

wagslick: Glad to hear it.

loomieD91: i hate the gm theft system i have probelms with my 2001 malibu occasionally

wagslick: Yes but then your theft light will always be on. Wrecks your resale.

SteelCity1981: irony is it's an anti theft system that won't even allow the owner to start their own car. lol

Adam Makowski: I have a 2005 chevy malibu classic. Same procedure?

mikqqqq1: what if you are unable to start the car because of the security ?

patricknedz: I agree on that. I have a 2004 Saturn Ion which does the same thing. Saturn was also owned by GM. They said they didnt find anything wrong with the car and cant figure out why it does that. I figured out it was the passlock from doing research. I just wish GM would run their business a little better and recall these cars that had been known for this passlock problem.

BobbyvilleMan: Thanks for the tip! I just had the exact same problem, figured I might have to call a mechanic to fix it, maybe even tow it to a garage. Luckily I noticed the theft light was flashing and figured that might have something to do with it. Left the key in the accessory position for almost exactly 10 min and the light stopped and I was able to start the car. I haven't tried the long term fix, but this is the first time this has happened so hopefully it won't start happening too often now.

David Lenon: This was an awesome trick. thanks for saving me some cash.

xadam2dudex: u sound like a real nice guy...u must be a used car salesman or banker

xaimerom28: this work's!!!!!!! after doing wath the video say , it work but i pas batery to a friend and the foking thef system wen on and all the proses going to the trash , i remove the power lock fuise anddd it work's thanks!!!!!!!!!

Derek Jr: ok in my 2002 impala i got 3 wires. 2 yellow one black. Can u help me?

xaimerom28: i bought a new radio sony , will this still work if i give'r a try?

Stacey Caulk: My prob is I can't get my car to start to snip the yellow wire :( I have a 2000 Grand Am SE I've had the car about 3 months and this is the 3rd time the car is on lockdown. Any ideas on how to fix this without car running? thanks

wagslick: You can. Shouldn't be a problem. Just know that your theft system light will always be on.

pp7k2: @Jeremy DePrato he means you split the yellow wire. u cut it in other words. then u attach the switch to both ends of the yellow wire you just cut.

Francis Capone: How come the Malibu has to be running when you bypass it???

vanbruz96: Please explain. I thought we only deal with the yellow wire. How do you add the 2.2k resistor, in series?

pincelito1985: hey can you tell me if this process will apply if im installing a remote starter, so i dont have to buy a bypass module? (2001 pontiac grand am)...thank you.

MrCatnoodles: your amp is taking your power

Paradigmdubstep: do you have to install one of these if your going to be putting a aftermarket stereo system in?

Dead2RiseMusic: you guys know anything about the service light when you change the deck?... i changed my deck and everyhint was fine i got the wiring piece i needed and it all worked out great. i then went to add a amp to my car and the service light came on and all the dash lights stopped working... any ideas?

William LeSure: Thank you for the video. Gm has used this in Grand Am/ Alero / Impala. This think is will work for years 1999-2006. But I'm not sure. Maybe you can help me with this. Because I'm have the same problem with a 2001 Grand Am SE I just replaced the Ign Switch/ with the chip in it. It was 160.00 I did it in 15 mins. And the security light is still on. Will this video work on my car. I'm thinking it will. Can you help?
