Could be a faulty ground wire. Not very rare to happen
I'd call a locksmith. The ignition wil probably have to be drilled and replaced.
Ignition switch worn out and needs to be replaced? After 20 years
get a new key or break ignition with flathead screwdriver or try wiggling old ket around Appended Aug. 7th, 2010: Possible pass-lock failure. this is a switch that is part of the ignition switch, and must be replaced with the whole ignition switch.
The ignition lock cylinder on a 2006 Chevy Cobalt is removed by popping off the steering column cover and inserting a screwdriver into the release hole. The cylinder can then be pulled from its housing and replaced.
Well, it sounds like the chip that is in your key may have broke or got stuck on a part of the ignition. I had that problem. This happened not long after I had had to have the ignition replaced?!?
Your ignition lock mechanism is worn/damaged (How much junk do you have on that key ring, Bub?). It needs to be replaced.
The ignition switch on a 1996 Mercury Tracer might lock up and release only when the shifter is removed from park and then put in the park position again because the sensor is getting worn. This sensor lets the ignition know that the car is in park and it is safe to remove the key. Check the shift position sensor.
You have an ignition Control Module that you can check that controls ignition timing Throttle Position Sensor that tells the computer where the throttle is so it can regulate and give the correct air fuel ratio.
Since you've replaced everything else associated with the ignition, try replacing the crankshaft position sensor. I'd bet that's your problem.
sounds like you have a broken ignition wire between ignition switch and fuse box
check the battery voltage, check battery cables, check ignition switch(where you turn the key), or check the crankshaft position sensor. cheers
I assume that you mean the ignition OFF position. Or do you mean the starter moter keeps turning in the ON position rather than just the START position. This may be a possible wiring fault. If the wires became overheated and melted through the insualtion, the START bare wire may be touching the IGN/ON bare wire. Cheers Malcolm
