I have a 2004 Corvette and have issues starting at times.It seems as though the ignition switch doesn"t pick up the chip from the key.Is there a part in the ignition that i need to replace?

I deleted the AI Bot answer and have modified it below. In cases like this though, the problem can only be diagnosed electronically using an auto electrician and a pro grade scan tool computer.

1. Faulty key chip: One possibility is that your key chip is faulty or damaged. Over time, keys can become damaged, which can cause problems with the ignition switch. You may want to try using a spare key to see if the problem persists.
2. Battery issues: Another possibility is that your truck's battery is weak or failing. If the battery is not providing enough power to the ignition switch (12.4 volts minimum), it may cause the system to malfunction. You may want to have the battery checked and replaced if necessary or at lease clean the terminals inside and out with a wire brush.
3. Ignition switch transponder problems: The ignition switch may be faulty, which can cause intermittent starting problems. If the ignition switch is failing, it may not be able to recognize the key properly, leading to starting issues.
4. Wiring or electrical problems: There may be issues with the wiring or electrical system that are causing the starting problems. Faulty wiring or connections can cause the system to malfunction, leading to issues with starting the truck.

Check your fuel pressure it should be between 30-45 psi with key on engine off.If pressure is below 30 psi replace fuel pump.

there should be a starter solenoid on the inner fender wall just behind the battery. this can be checked with a multi meter. there are some really good videos on you tube that show exactly how to go about checking it. just search starter solenoid. sounds like it is probably where your problem is.

sounds as though the computer chip that is in your key is no longer being read by your cars security system. these chips are a basic resistor and have been known to go out from time to time. one thing we do at the lockshop to fix this issue is to hard wire in a resistor to the ignition itself ( of the proper value ). this basically by passes the key security part of the system and you will never have to worry about this problem again. a mechanic or a locksmith can do this bypass for you and it will save you the cost of a new ignition switch which is very expensive. ( the resistor costs about 5 bucks -- and the labor to install is about 75 dollars -- depending on what part of the country you live in ). this will also allow you to just get regular keys made for for spares at the cost of $2.75 instead of $29.95 for chipped keys ).

It is your vats system it is locking you out. It is not reading the ignition key chip. You can by-pass the system with $5:00 worth of parts from your local radio shack. You must read the resistance across your key chip first then go to radio shack and pick up the resistors needed to match your key chip(they will assist you mine read 1850 i have a 86 vette), twist/tie them together then solder & tape them up with electrical tape. Bend them into a u-shape, locate the the 2 wires that run to your vats logic module that is tied into your ecm, should be in the middle area of your dash next to your radio(yellow and brown in color. Cut those 2 wires and add your (radio shack) resistor series between them and happy motoring no more vats problems for ever. Good Luck

Yes Get the right key at a GM dealer, take along the car serial number because there are several chip options and they will have to look it up with serial number

Car doesn't turn over,but ignition turns on? Doesn't happen all the time,it just happens.. If I let it sit for a while it all of sudden turns over and starts. Happened twice this year..

If the key is all the way in, it should turn the lock, with a screwdriver. It might not start without a chip if it has one, but if you hold the chip close by it should start, then I would get a pick, a dental tool, something real sharp, fine, hard, and pull the key out. Get a new one made, Hope this helps.

REMOVE THE INFO PANEL IN THE CENTER. THE RELAY IS BEHIND THE INFO PANNEL. YOU CAN HEAR THE RELAYS CLICKING. YOU CAN CUT THE WIRE OF THE RELAY TO STOP THE RELAY FROM ACTIVATING THE IGNITION CUT OFF.
IF NO OIL PRESSURE THE ENGINE WILL STOP, CHECK THE OIL PRESSURE. GO TO CORVETTTE FORUM .. NEED SLEEP !

Occasionally the shift lock cable can stick and cause this problem. Try jiggling the shifter and see if that helps. You may need to replace the cable.

The chip in the key is purely electrical and will not prevent the key from mechanically turning the ignition switch.
