I do not have a remote that is already programmed either.

I work at a Dodge dealership so you are in luck I have access to the service computer from home. Here are the programming instructions for a 1999 dodge durango:
Program Method B (Customer Program Method)
1. Press [LOCK] button 5 times at 2 second intervals to resynchronize transmitter. Attempt
to function transmitter, if working as designed discontinue programming.
2. Turn ignition to the run position (Allow ignition chimes to stop).
3. Using original transmitter, press and hold the [UNLOCK] button on the
transmitter for between 4 and 10 seconds.
4. Continue to hold the [UNLOCK] button and press the [PANIC] button. A
chime will sound to indicate that the transmitter programming mode has been
entered (Allow 3 seconds for chime to sound).
5. Press a button on all transmitters to be programmed into the system
including any previously programmed transmitters; a chime will sound when
each transmitter has been programmed.
6. Turn the ignition to OFF position to exit the transmitter programming mode.

sorry I can't help then
