3800 New Key

[BlackGTP]

I have a new key for my Grand Prix since I lost my main key that I got from the dealer. Said something to let it sit in there with power on for 20 minutes for it to program and work.

Ive done that and the car turns over then cuts out. I cant find anything in the manaul? What do I need to do.

It's a little more detailed than what you have tried.
Here is the procedure:

1. Put the newly cut Master key into the keyway and turn it to the ON (RUN) position. A "Security" indicator light on the dashboard will stay on for 10 minutes.

2. Within 1 minute after the indicator light goes off, turn the ignition to "OFF" then return to the ON (RUN) position. The indicator light again will stay on for 10 minutes. (DO NOT REMOVE THE KEY)

3. Again, within 1 minute after the indicator light goes off, turn the ignition to "OFF", then return to the ON (RUN) position. The indicator light again will stay on for 10 minutes. (DO NOT REMOVE THE KEY)

4. When the light goes off for the third time, the new key is programmed into the computer and will start the car. Remove the key and then re-insert it into the ignition lock and start the car.

All previously stored codes will be erased. To stop the process at any time, simply remove the key and use an existing key to start the car.


Hope this helps!!!
