I don't have that on my key.
Here is everything that I have asked and got an answer for so far. I did a lot of copy and pasting so I hope it makes sense.
'98 Grand Prix GT-when I open the door the chimes are going, put my key in the ignition and turn it to start, nothing happens. When I use my aftermarket remote it will start the car but shut off after 5 or 10 seconds. It all started when I let the car sit for 6 months and the battery went dead. Now, I have replaced the shifter celinoid, ignition switch but not the cylinder and key. No power to the purple wire on the starter when I turn the key. Someone told me to reflash the computer, reprogram the key. I don't know if it's something to do with the security. Can you give me a list of things to try?
The problem is most likely the ignition lock cylinder, there are two tiny wires coming out of the cylinder that break over time. You can replace the ignition lock cylinder or you can bypass the system. If you want to bypass the system, use an ohmmeter to find the resistance across the chip in the key. Then go to Radio Shack and purchase a resistor of the same resistance value. Wire this resistor across the two white wires coming out of the steering column under the dash. These white wires are encased in orange insulation where they come out of the column, then break out of the insulation near the connector. See illustration below.
I think I will probably replace the cylinder. Is it hard to replace?
Not that hard to do. You must remove the steering wheel, then the lock plate under it and then take the turn signal switch loose. You do not have to totally remove the turn signal switch, just lift it up. There is a single bolt that secures the lock cylinder into the column.
Is there going to be any trouble because it has an air bag? I have never taken off a steering wheel with a bag b/c I was afraid I might mess something up.
Removing the air bag is pretty simple. Remove the air bag fuse and disconnect the battery before servicing the vehicle.
Turn the wheel 90 degrees and use a flat bladed screwdriver to release the spring clips on the backside of the steering wheel to remove the airbag. There are 2 on each side.
In detail - how do I remove the steering wheel off of a '98 Grand Prix? I have to replace the key cylinder. Also, I do I check for resistance on the key?
dont need to ohm the key for resistance if replacing the lock cylinder with a new key, but you will need to perform the security relearn procedure below:
Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to RUN. You must turn the ignition OFF before attempting to start the vehicle.
