when you buy an ignition switch you have to take the template key to a locksmith or the Chevy dealer and get the chip in the key. Your cars computer won't read the key and therefore won't start. No signa no turning over..
u might have broke something the actual ignition lock cylinder, that would be my guess from the sounds of it.
I have changed an ignition in one. I used a pneumatic cut-off wheel to cut straight slots in the blank faces of the two bolts that retain the lock cylinder. Then, I used an impact screwdriver to remove the bolts. when you get the new ignition lock cylinder, you can use a large flat screwdriver to re-install the bolts.
If the key will turn in the ignition cylinder, the only other fault the key can have is a missing or damaged resistor. The resistor is in the middle of the key and looks like a small black oval. The resistor has one of 16 specific values and is "read" by the Pass-key module. If you have a vehicle with 30K or more on the odometer that won't start, and everything else is good, (battery, starter etc…), the most likely problem is the two little wires that connect the Pass-key module to the ignition cylinder. These wires have to flex each time the cylinder is turned and eventually break at the ignition cylinder. The only reliable repair is to replace the ignition lock cylinder and key. New Ignition lock cylinders do not come with real ignition keys, only a temporary key to identify the cuts. If the cylinder is changed you have to purchase a new key separately to match the old key resistor and then cut to match the new lock cylinder.
It only uses ( 1 ) key , unless a lock cylinder has been changed
You should check the wires that are in the steering column to the ignition lock cylinder. They tend to break easily.
It would help if we knew the year, make and model. It has to be something you did when you changed the ignition.
Your having a problem with the passlock system. Contact your dealer and thell them the situation. They will need to change the ignition cylinder. I had this problem a couple fo years age and it took 5 trips to the dealer before they got it right. They changed the computer module , some sensors, and many other things. But, changing the ignition cylinder did the trick.
When they develop a fault.
No, you do not.
possibly due to loss of ignition... When was the last time you changed plugs wires coil etc...? check that first...
sure it can
Misfire Answer Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
