Passlock System

I will try it. It doesn't crank at all.

Does not crank over with starter or does not start?

I have a 97 Malibu. I have experienced the problem of inability to start when Theft ligt is on. I now have no power in my panel so I do not know if the theft light is on or not.

Does anyone have any suggestions??

I have had them checked. All are okay. I have the same symptoms as when the theft loss light was on.

Did you check them for 12 volts key on power on both sides?

No matter how long I leave the key on the security light does not go out. Only when I try to crank it then it comes back on when I stop. I tried the learn system you spoke about still doesn't crank.

Now my 02 malibu has the theft light on all the time, it turned on one time , I had to wait for 10 mins, after that I can always start the car, but the light is never off.

I went to my mechanic, and he told me better not to clear the error code, otherwise I might have to wait for 10 mins again.

Now my car seems ok except the light is on all the time.

Can anyone tell me if there is a problem with it, for example what if my battery die, will my car never start again?

I have a 99 grand am 3.4. just like everyone else, i'm having passlock problems. the dealer want's a grand to fix it and they don't know if it will fix the problem. so i let a friend of mine look at it. he had it for a week and couldn't figure out what was wrong with it. so he gave it back and told me to burn the car.i just ordered a body-kit, hood and fenders for it so i want it to run. i wanna cut the yellow wire but don't know what kind or type(rating) switch to install. please let me know so i can be done with this passlock crap.

i have a 2004 alero with crank no start security light on. tried to reset nothing happens. what else can i do.

[mikepeer]

i know the is a malibu forum but i have a 2000 impala that wont crank. i jumped the starter and the car will start and run for about 2 seconds and die. you can hear the fuel pump run when the key is first turned on. the key can be removed in any position, i would assume that it's going to have an effect on the passlock system. from what i've gathered on it the passlock has alot of problems. my question is.....if i get a new ignition switch..is it possible to "reset it" (10 min thing) or will a dealer have to do it since it would be a new set. when you first turn the key on it flashes from sec 3 times to batt and then to service. if i wait 10 mins the sec stays on solid, but no crank. so i cycle it off then on..still solid...do it(without waitin 10 mins) again then flashes again.(by the way i do have a charger on it the whole time) i would try the yellow wire mod it i could even get it to start.
i have a otc genisys scanner that i'll try to read any codes tomorrow, or foes it need OE software for the passkey?

and when you do the reset do you turn it to the on pos and try to start after 10 or just cycle off and back on 2 more time before trying to start?

any help would be great. this is an old police car and only has 20K on it, could be a cheap daily driver if it would ever start.

For those having issues with the PK2 system try this....

Do not do what the guy says in the 2nd post. He doesn't know what he is doing and obviously got banned anyway.

If you can't get a resistance value and you car isn't starting then pick something around 2.3 to 8.5 ohms. At this point you'll have to do the PK2 relearn procedure. When doing this it is recomended to have a battery charger on because you need to cycle the igntion on for 10 minute intervals or when ever the PK2 light changes state from when you started doing this. When it changes, you need to shut off the car and then try to start it again. If it fails to start, leave the ignition on and do it all again. It usually takes 20 to 30 minutes to perform this. Somewhere on here there was a detailed instruction from a GM tech that spelled all of this correctly.

To the moderators, could you deleate that post from the banned person in the above link? He mislead people because if you do what he did and your car's battery goes bad, it'll never restart again until it sees that resistance code that's stored in the BCM.

I installed the toggle switch two days also. everything seems to be working fine. Am I to understand, that if my battery dies, i will not be able to restart the car regardless of the condition or postion of the toogle switch.
