Ignore the install new computer and disconnect battery parts.
1. Disconnect battery
2. Install new computer
3. Reconnect battery
4. Put emergency brake on to disable daytime running lights (this step is required!)
5. Make sure all doors trunk and hood are closed leave driver window down and reach in threw window
6. Try to start. If it doesn't start, leave the key in the on position for 10 min on 97-03 cars and 15 min for 04 and newer cars. The security light should turn off after this amount of time.
7. Turn off ignition for 3 seconds
8. Try and start the car. It probably won't start. Repeat step 5 two more times.
9. If this doesn't work disconnect battery for 5 seconds and then try and start the car.

If that doesnt work, try this one:

1. Disconnect battery for 10 sec.
2. Reconnect battery
3. Turn key to ON position
4. Do not try to start vehicle, just quickly click to RUN position to engage security light
5. Let vehicle sit with key ON for 35 min.
6. Attempt to crank vehicle. Once vehicle is running, the security light may still be on
7. If security light is still on, turn key to OFF position for 5 sec.
8. Turn key to ON position and security light should turn off
9. Start vehicle and enjoy new PCM

I'm glad I happened upon this post. I need to get a second key cut for my GP since I only have one. I'll have to come back to this when I get one.

On 04 and up to relearn an additional key you just have to start the engine with the origional key then shut right off then start it immediatly with the newly cut key and it's programmed

Did it on my 04 and current 06

Thats all I did to my 03. Start it with the original and then start it with the new key.

lol..is this like the "Go get the potatoes out of the basement", or "Take the flag off the flagpole" trick?

Hmmm... to be honest I didn't think of it like that, but now you say it... Sounds like it haha
