The ignition key has a small pellet in it which has a precise electrical resistance. There are about 30 different values. In order to start the car you need the correct ignition key to turn the lock and a pellet with the correct resistance. If the computer measures the resistance incorrectly, it disables the starter and shuts off the fuel injectors for 3 minutes. The message "clean your key" should appear on the computer screen. The problem can be caused by several factors.
What Im trying to say is you'll need to get the key reprogrammed if you've cleaned it and the car still does not start. This is a "security feature" to make sure that a duplicate key i.e. cut from yours will not work in your car as they have special resistor chips in them the car recognizes the value of.

When I try to start car, it won't start and security light blinks. I'v e had to ignition switches put on before and I had a new key made. Car still won,t start.


If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.
