Car's security light came on last night, I troubleshooted: When I turned the key around; it was inserted backwards, the light went off. Not sure if that was the problem and not sure if someone tried to enter the vehicle while I was in the store.
Now, in reference to the car not starting this extremely cold and windy morning: It was recommended that I check the horn to see if it blows normal. I will check that. However, do you have any other suggestions?

Re: 2002 chevy impala won't start...
Check battery with a volt meter and see what kind of volts are in there. (should be at least 12) If lower, re-charge battery and clean terminals. (make sure you know radio code before removing terminal ends, and how to restore radio). Quick way to check battery is to leave the door open and look at the dome light, If it dims substantially when you attempt to crank engine, battery is likely low.

Why do think the key security is bad? If you still have a factory key, this is not the problem...if no factory key, you can take your VIN number or original key to GM dealer to get new key that they will program for you...Check for dirty battery connections:)
Is the security light on or flashing ? The yellow wire goes from the key switch to the neutral safety switch, then to the starter. So bypassing the neutral safety would make the starter crank the engine, but would have nothing to do with the rest of the engine.
i would say when the person broke into your car they set off the security system which stops the car from starting, the way to reset the security is to put your key into the ignition turn the key until all the dash lights come on and let them stay on about 15 minutes after the 15 minutes have expired turn the key off and wait about 3 seconds and then your car should start. hope this helps.
This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.
After you replace the ignition switch turn the key to start the car and release leave the key were it stops after trying to start wait 10 minutes until security light goes out turn key to full off position then repeat the above procedure two more times for a total of three on the 3rd attempt to start car wait for light to go out then turn key to full off positoion wait 10 seconds then try to start car body control module should learn new pass code and the car should start.

does your key have a small black chip at the base of the key if so it could be bad or the ignition could be bad it reads a resistance and if it is off by a few points it will think that the car is being stolen
