Car Won't Start and Security Light is On on Buick Park Avenue

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.

turn key to start position and nothing happens, no power to starter solenoid from ignition, security light does not come on or flash unless the key is out or in the off position
Car won't start and security light is on ran fine yesterday
I need to have this checked out, as well. Stranded numerous times & unable to start the car, only to find it will start at times & seem to work just fine...then stranded again in a parking lot or someone's drive, besides my own...bummer!!!
Car ran fine for the last 950 mile trip we took, after we were home it set for 5 weeks. I went out to start the car - the security light is flashing and will not turn over or start.
for 4 times during the last 6 months it had no power to start the engine. Battery wwas checked 3 times and AAA and dealer could not find problem. Went to NTW and they examined the car and said battery was bad. 7 weeks later it did not start again. There is no sign in the lights and no noise from the start attempt. I do believe it is electronics but I need something to point my dealer at the problem.
security light stayed on one day, but car ran fine. now it may stall as I drive, giving me no indication.
REPLACED IGN CYLINDER AND KEYS
The key refused to go into the ignition. When I was finally able to get it in, the ignition wouldn't turn because the switch is broken. I'm having to pay a lot of money to have a mechanic come to my house to replace it, since I can't get it started in order to drive it to a shop.
My car will not start after I parked and have been driving it all day. When the car is off the service engine light is on, but it is not on when the car is on. I do not know what to do! Usually when I get out of the car and lock the doors, use the key to unlock the doors and then start it it works but not today!!
I hammered out the ignition
key replaced. car started and ran for 30 minutes and cut off. security light flashes when key is inserted but will go out when in the run/on position.
Car was stopped after driving on the weekend. No problem or other issues with the starting were noticed. On Monday car would not start. The battery level gauge showed very low charge. No lights were left on overnight. Replaced battery but still no ignition. It seemed there was still no power to the starter. Got new starter but mechanic said the fault code is for security. He said I need a new ignition switch in the steering column (dealer item) and a new key with the chip. Waiting for the outcome after repairs tomorrow. Will be returning the new starter because it is not the fault. Hope to start after the ignition switch and a new programmed key (existing key would is not usable)!!
Car wont start but have power security light flashes
My key will no turn, at first I could let the steering wheel up or down then I could get it to catch, now I can't get it to catch
anti theft lock requires four digit security passcode
Car wont start i think its the security system locked
car will start after system sets a condition that key chip failed while running. No repair performed, security light stays on.
My 1991 buick park avenue 3.8l I had replaced the cam and crank sensor the interupttor (magnet) the engine control module, starter. Now today I'm replacing the ignition switch and cylinder.hope this ends.seems all of these will fail if they have not for u yet.
My solution was to bypass the key cylinder by finding out the resistance of the chip and placing resistors equal to that same resistance in line to the anti- theft system.
