Keyless Remote FOB programming instructions

I've lost on of my original key for my 05 Pacifica. Just bought a new one had it cut but now I need to program it. Anyone out there with the instructions. I really don't want to get hit over the head by the dealer.

I think its dealer only, since its the same remote as the Mercedes.

the remote is the most expensive part for the pacifica the price has come down from $131.00 to $60.00 each to program them its aprox 1/2 hour $40-45 dollars if anyone charges you more than that your getting taken.
