Car Won't Start and Security Light is On on Oldsmobile 88

Problem Description and Possible Solution

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

I try to start my car but it never wonts to turn over i thought it was my starter found out it was my anti theft system how do i override it
Car security Light flashes when turn key to start Have Interlock on car..had the Lifesaver Tech check their system and He told Me it was the Anti-Theft System that was preventing the car to start Is there a recall for this problem even afer All the years passed Have owned the Car 6.5 yrs this being 1st this problem occured
At times the car will not start and the security light comes on. Have to turn the key to the 'almost start' position and let it 'reread' the key. When the security light finally goes off the car will start. Some times it takes only a couple of minutes, sometimes you will be sitting in the cold or blazing heat for approximately 10 minutes. This definately needs recalled!
I began to have problems starting the car. I would turn the key and the car would click, no engine turnover. I noticed the SECURITY light flashing and read about the problem. Then after a couple tries the car would start. This went on for a couple months, now it won't start at all.
Same problem. Car would not start and sometimes not even turn over. Was told anti theft system was the problem. Tried new key and that worked for a short period of time. Finally bought a bypass module from and installed it myself in just over 1 hour. Problem solved!
Same here,here's what to do,check ohms resistance resistor in key.I called an electronics place that sold me all the possible resistors for that car.There is a kit with 15 resistors,pick one that matches key,connect between 2white wires.This bypasses the need for contacts in switch and resistor in key.INTERSTATE ELECTRONICS IN HAZLET NJ knew just what I needed,AND ONLY COST 5 BUCKS FOR KIT.
key turns over engine but fails to start some system keeps the fuel injectors from getting fuel..i pull out key and wait 10 minutes for so, and it runs...
security light is blinking (perhaps always did) and when I turn the key to start the car, the gas gauge goes all the way up and that's it.
Security light is on, and car will not turn over. Replaced the started. Hope its not that awesome plastic intake that GM produced, as it was replaced at the dealer less than 7000 miles and one year ago at the cost of 1000.oo
car randomly won't start. usually starts on the second try, but occasionally takes 5 minutes or more.
Car would not start. I took it to the mechanic and he replaced starter and did other repairs and I still had the same problem. I googled care problems with the 88 olds and it said anti-theft system that uses raised chip key .So I tried a key that I seldom used and it started the car. I took it to the dealer and told them what I thought the problem was and they fixed it. the car works find. I now have over 170,000 miles on the car and it's running just find.lock cylinder was replaced and I got new key.
The same thing happened to me. I have to have the whole ignition lock cylinder replaced. its gonna cost me 425 at ron goodmons auto repair
My car is having this same issue and is in repair now. It's just that the person I bought the car from only had one key and no spare ignition key. The key we have is worn and the dealers can't seem to be able to cut what we need to get the vehicle started. We are trying to see if the owner had a spare and if not can the dealer use the VIN too create another master key to this ignition!
