I need a new ignition key for my 1998 Chevy Lumina,

it has a thief ignition lock. didyou buy a new one if so it needs to be regramed by dealership . if it is a used one then you need to change the thief box. I have a 1996 montw carlo and had the same problem

You will be sorry to hear that there is no way to straighten bent valves. They need to be replaced with new ones, and refit to the head. This situation makes me worry about the crank bearing process: was the CAUSE of the bearing failure resolved? Was the crank repaired and turned? Was the block measured and issues resolved? and Finally was the bearing clearance measured with plasti-gauge?

disconect linkage at transmission should be able to push into garage,keys at locksmith high price about 100.00

You have a chip on your key,Your ignition has wire that goes bad,You have to get a new ignition and key that has a new chip.

turn the wheel left or right and see if it turns check the key if it's bent or wiggle the key at the same time it might get frustrating but it might turn had a chevy do it all the time on me.If not you will need a new ignition switch and keys.

You may have to get a new key cut if the tumblers in the ignition lock are not being lined up to unlock the ignition. If the key's was bent in the ignition lock, the ignition lock may be bad and need to be replaced with a new ignition key. Try replacing the ignition key's first, but if you have a spare key. Try that first and if the spare key's don't turn the ignition lock, then you may have to replace the ignition lock. Good luck and keep me posted. oh and try moving the steering wheel left to right as you try to turn the ignition lock. 

Looks like ignition current is not being available to fire the fuel/air injected mixture from the plugs. Remove the cable tip which connects TO any plug. Hold the cable tip to any metal part of the engine block or any part of the body where the metal is exposed(not painted). Ask a friend to turn the ignition for starting the engine(vehicle). If the cable tip produces sparks, then the induction coil is OK, but since you have stated that clicking sound is heard which is actually the relay's which tries to get the induction coil to generate high current required for producing the spark to ignite the fuel & air mixture in each cylinder, thus starting the combustion required to turn the engine & subsequently power. So check the induction, belt tightness and finally the "Distributor"in the sequence as stated and you will be able to diagose which one of the above are malfunctioning............sodeep

Solder and shrink tubing work fine for that. That is for the pk2 theft module that tells the car that you are using the correct key with the chip in it.

After you put the new fuel filter back in, make sure your fuel pump is actually pumping, either by listening for it to start when you turn the key on or by cracking the fitting at the fuel rail (after disconnecting your ignition hot lead first) I assume that you have checked the fuse/relay... rick
