Dear Car Fix: I have a 2003 Alero Oldsmobile with a peculiar safety system. The security light comes on at least once a week and after approximately three weeks the car will not start. After I let it reprogram itself for 10 minutes, it's OK. Is it possible to disable this security system?

Dear C.W.: Here is a step-by-step procedure to disconnect the security system:
Pry up the plastic molding from around the radio/heater A/C controller and from around the gear shifter. Detach the heater A/C module from the molding by removing the four 7mm hex bolts from the backside. Take out the three 7mm hex bolts to loosen the radio. Put the key in the ignition and turn to "on" position, apply brake, and shift into "drive" or lower gear. Turn the heater A/C module to the left, sideways orientation, and pull out the radio. Disconnect main wiring harness from back center of radio if there is not enough slack to take the radio out past the plastic molding. Leave the antenna connected. Look inside and to the left at the back of the ignition cylinder assembly. Locate the thin yellow wire, which is bundled alongside the thin white and the thin black wire. You may have to stick your hand in and fish a bit to grab this "thin wire trio." DO NOT mess with the main rear/downward ignition wiring harnesses (one of which contains a thick yellow wire -- leave it alone).
Isolate the thin yellow wire from the two others. As a precaution, reconnect the main radio wire harness, and let the radio hang to the right side. Put the key in the ignition, and put the car back in park. Start the car. Cut the thin yellow wire with the car running. Tape both ends of the cut wire. Place black electrical tape over the "security" light (less annoying). Turn off the car engine. Disconnect the radio main wire harness to reinstall the radio, if necessary. You may need to crawl under the passenger- side dash to push the main wire harness back into the radio while holding the radio from the front. The rest of the installation is the reverse of removal. Your life just got a lot better if you want to keep driving this car!

After driving the car for a few months the car just wouldn't start. I would tow it to a shop and it would start right up. Then a few months later it would do it again. After about the 4th time and getting the ignition switch (i think that what it's called) It ended up being the harnest wiring which cost around 350 dollars.

the engine turns butdoes not srarts

Intermittent no crank or start, only lights on dash. Dealer states could be one of three problems.
Neutral switch, starter or ignition switch.

same thing happened to me, i was running errands on my way to work. I must have stopped at 7 different places turning my car off and on each time. on my last stop when i was about to go to work it wouldnt turn on. i got it looked at and the dealership that sold me the car said it was the pass lock sensor that had gone bad, but less then 6 months ago they replaced the ignition switch. when they replaced the ignition switch they couldnt get the tumblers back into the proper allignment, so that meant i could remove my key from the ignition while the car was on.
