How to program chip on 04 Dodge Ram

I need to program another key to a 2004 Dodge Ram 3500 so I got the key from the dealership with the chip in it I just don't know how to make it learn the trucks code.  Any help is appreciated.

uh oh..i just read something elsewhere saying i need 2 working keys??  Thats going to be a problem considering I only have 1.  This is what I've found so far..

here is the key you are needing for $13 http:///.com/ebaymotors/dll?ViewItem&item=7924048334&category=40016

Add Duplicate Key (Requires two existing keys) 1. Insert one of the two existing keys into the ignition lock and turn to the ON (RUN) position. 2. After the key has been in the ON position for at least five seconds but not more than 15 seconds turn the lock back to OFF3. Remove the key and insert the second existing key and turn to the ON position within 15 seconds. 4. A theft alarm light should illuminate after the seconds and a single chime sound will indicate entry into the "Customer Programming Mode." 5. Turn the key to the OFF position within 60 seconds and remove the valid key. 6. Insert a new key and turn it to the ON position. 7. After approximately ten seconds, a single chime will sound and the theft alarm light will stop. Wait five seconds and turn the key to the OFF position. 8. The above steps must be repeated for additional keys

Can I not put the existing working key I have in twice and pretend its a different one?

No....you need two keys. Otherwise the dealership has to program it with a scan tool.
