    My sons car is in my gaurage where it has been for a month now...The dealer says it is the pass lock...Need help on how to solve this problem

  • Anonymous May 06, 2009

    I have this same problem. I bought my 2001 Alero in June 2008 w/ 14,500 miles. Now 10 short months later, I'm having to deal with this ridiculous problem. No matter what site i go to in researching this problem, everyone seems to just settle for this "10 minute rule". Who the heck has time to bother with that? And what kind of manufacturer actually tells you this is the problem solver - see page 2-20 of your manual. WHO DOES THAT?!?!?! Can anyone tell me what they did to get rid of this issue, or am I supposed to just deal with this laughable problem??

While I've never had this issue, the fix is pretty easy:

  1. Turn car to ON position (without starting it)
  2. Leave in that position for 15-20 minutes
  3. Turn off.
  4. Start car.
This issue is with the PASSLOCK system in the car.

I just replaced the starter in my 2000 olds alero and now it wont start it keep flashing securty....it thinks it is benig stolen....how can I fix this


Most likely you replaced the starter because it wouldn't crank over. If this is correct and the security light was flashing before replacing the starter, then most likely you have a problem with the pass-lock system. If your ignition cylinder is located in the dashboard, you will need to remove it and replace the passlock housing.

Car ran fine night before...next morning would not start. Replaced fuel pump, filter and switched relay but still had no luck. What else should we do?


CHECK TO SEE IF SECURITY LIGHT IS STAYING ON WHEN YOU TURN THE KEY TO RUN POSITION(NOT START) NORMAL OPERATION IS SECURITY/ANTI THEFT LIGHT ON FOR A FEW SECONDS THEN SHOULD GO OFF. IF ITS STAYING ON VEHICLE IS IN THEFT MODE WHICH WILL DISABLE THE FUEL INJECTORS BECAUSE CAR THINKS ITS GETTING STOLEN. MOST LIKELY CAUSE FOR THIS IS PASSLOCK SYSTEM(SENSOR IS LOCATED IN STEERING COLUMN)

2001 Olds Alero Wouldn't Start


I had a problem similar recently, just wouldn't stay on. Found out that there is a flaw with the sensors on those cars for the ignition "talking" to the computer's Passlock II thing. The car thinks it's getting stolen so it engages the anti-theft which turns off the fuel injection. You just have to reset the Passlock. Turn the key to the first On position where you have radio but no windows, leave it for 10 minutes until the little Security light turns off. Turn off the key then start it.
Don't know if it was your problem, but just so you know, the sensor part will eventually start failing with this car.
