My mechanic said there is a board that is bad in the car and it costs $400 to $600.00 to replace. He was presently putting one in a another lady's car that was at the shop. So far he said it works. He said if you don't replace it eventually it will not start period. Any I have also notice that my cigarette light will now not work??? not sure if connected.

I have a 2005 GMC Sierra. From time to time tyhe truck will not turn over. The security system prevents it from doing so. I have waited 10 minutes to over night with no sucess. When I take it to a dealer, it starts whern the technician gets around to looking at it. Is this ths passlock problem or the ignition lock problem? Where can I find out how to change out the lock?

I experiencd my 1st passlock problem yesterday on my 2003 Impala. I don't know what happened but after a battery check at WalMart parking lot and waiting about 20 minutes it finally started. I do hope there is a solution besides putting out $500.00 dollars or more. I just spent $1,500.00 on servicing. I should have put it in a new auto but I have had no problems until this security light issue.

let's all get together and go to G.M. corp. office and give them a piece of our mind. a tel call does not work they don"t care they say take it too chevy dealer. who pays, we do.if they would tell us what was wrong maybe we could fix it ourself if the dealer fixes it the cost will be 3 or 4 times more. I am getting sick of GM. they will recall this in about 6 years if you are the original owner, big deal it will be in junk yard by then

2004 impala...same thing. freaken' passlock. car is sitting on the side of the road near my house. dead. i took the keys out of the ignition to open the post box to get my mail. god forbid I try to start the car to go home! I am going back out to walk down the street again for the third time to see if I can get it to start. It's about the fifth time this has happened. Been to the dealer to get it "fixed". Temporary fix. Will buy another make of minivan/car very soon. This sucks cause it's a good car otherwise. I'm frustrated. The last time it happened I had my 3 kids in the car in the heat. No AC... nothing. Took 45 minutes to start that time. Not fun. OK I'm done now. Thanks for reading this...

I've been dealing with this problem for over a yaer. It finally made me late for a new job. I've been doing my homework-studying posts on this subject. This Is what I'm talking about. I dont want trial and error with the dealer. Nor do i want to spend hundreds of dollars. My first contact with a(dealer )mechanic-"No, The passlock cannot be bypassed. You need a new bypass sensor $300.00. From the star I know more than he knows already. My question-Did you perform the fix yourself? I want to be where you are with your car. Trusting it again. moewave@yahoo.com

Also a lie. I knew they lied as soon as they said it. I challanged everything they did. Finally they got pissed off and told me to just come and get the car. The real problem is oxidized contacts on the passlock. They have to be cleaned even if they look clean. High humidity areas are most at risk for this. My car is now fixed and I trust it again. Do your homework and don't let a garage tell you you have bad parts in the system.

The real issue is not the ignition passlock system it is your ignition switch. Inside your ignition switch one of the contacts that closes when you turn the key in start position is partially burned out. Due to the imperfect contact, there is a voltage drop on that contact so the signal generated by the hall sensor is getting out of range therefore the BCM (body control module) will not recognize your "key" rather said the signal generated by turning your key and it will prevent the car to start for 10 min. Most of the times after 10 min it will start. The fix is not easy but it is cheap. All you need is some sand paper. You will have to take out your ignition switch. There are expalnation on the web on how to get to it. Once the switch is out take it apart and clean the contacts inside (there are 5 of them). One of them at least is burned out. Also bend the steel springs that are holding the contacts closed or open so they will push the contacts open or close properly. I did this and had no issues since-3 years ago. You can repalce the switch if you are willing to pay 110 dollars for the part (I was not). Good luck with your repair.

We have also a 2004 Chevrolet Impala. I have been reading so many comments about the Defective PASSLOCK SYSTEM. We also have experienced No-Start days, many of them. I agree since G.M. and the Passlock manufacturer will not adress this problem that a CLASS ACTION LAWSUIT needs to be started against both, G.M. and Passlock manufactures as well as a recall to bypass or totally remove these systems. What IF, as they say, God Forbid, someone is DYING and the car WILL NOT START to take this person to get medical attention. The Feds need to hold G.M. and the Passlock manufactures accountable to us, their customers,the American Public.

to completely reset the system you may have to repeat the process 3 times to get the light no not come on..have to to do this on 2000 chevy a lot..this will do a total reset on the alarm system be patient because you will have to sit for 30 minutes...... pain in the a$$ but it works

there is a way to bypass the Passlock security which involves installing a resistor in the passlock wires near the ignition or at the BCM.YOu have to find the right wires and measure the ohms with a meter and buy a resistor close to that reading and install it between the passlock wires.I think my ignition module or key tumbler is bad as I plan to replace one or the other after i due more research.

I have a 2003 Impala and I was told to do this 3 times this by a mechanic too. I tried this process and it worked for about 2 weeks. Now my car won't start about every other day. I never know when it is going to happen but it always happens when I don't have the 30 minutes to wait. I cannot afford to be late for work or getting my child to school. I wouldn't mind spending the $ to have the dealer replace the parts but I am worried that it won't fix the problem as so many others have stated.
