Question about 1999 Oldsmobile Alero
I read in another post that you could advise how to bypass the security feature in the 99 Oldsmobile Alero and was wondering if you could tell me how it's done. My mom's Alero has issues with the security light flashing and then the car won't start. She waits the 10 minutes and then it may start or she may have to continue waiting 10 minutes again, and again. We would like to bypass the system but don't even see a fuse that we can pull. Please help!
There isnt a fuse for the theft system. You need to take the coloum cover off. Should be 3 screws and you will see all the wires in there. The ones you need are three togather. White Black and Yellow. Get the car started and cut the yellow wire. The theft light will come on and stay on but will bypass the theft system. If it is a 2 wire system you will see two little metal strips on the upper side of the key. You have to use a ohm meter and measure the resistance of the strip in there. Its a resistor used to tell the theft computer the key is in there. Anyway find out what the resistance is and buy a resistor from radio shack and look under the steering wheel for the 2 very small guage wires in a yellow cover....NOTE not the air bag wires. Simply cut those wires ( the 2 white ones) and on the set going away from the steering wheel strip the wires and put the resistor one one wire and the other end of it to the other wire....That will disable that system. If its the 2 wire and you have issues getting it simply take the car to a car audio place that does remote starts and for a nominal fee they will do it for you. My records show that it has the 3 wire system.

I own a 1999 Alero and unfortunately, this happens to me. I read in another post that you should turn your key to ACC, wait for the security light to stop flashing or go out, then turn the ignition off, then back on again to restart.I tried this just a couple of minutes ago and low and behold, it worked! Still, it 's a pain in the wazoo!

I cannot believe it! I did what they said on solution #3. Turned the key to ACC It took about 1 to 2 minutes before the security light stopped flashing. Turned the ignititon off and then it started back up on the first try. Excellent!

So I have a 99 alero. Same problems as everyone else. So far i have replaced the BCM, replaced the ignition lock cylinder and passlock sensor, and have done the bypass. the car is still doing the same old thing. Cranks then cuts back off after a few seconds. With each replacement i did the 30 minute relearn process, yet the problems still exist. ANY OTHER SUGGESTIONS?
