2003 3500 remote programming

[MyronW]

I've gone through the "on-off-on-off" routine trying to get the RKE into program mode, but no joy. Anyone know of an alternative? (short of taking it to a dealer)
Is there a test to see if the system is defective or disabled?

Transmitter Programming
Important
All transmitters which are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter. Up to four transmitters may be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number on the transmitters are for reference only: #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available. Use care to program the transmitters correctly.
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Use the scan tool Remote Function Actuation Special Function: Program Key Fobs in order to place the remote control door lock receiver into Program Mode. The doors will lock and then unlock in order to confirm program mode.
Important
The scan tool must stay connected until all of the transmitters are programmed.
4. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of 15 seconds, the doors will lock and unlock in order to confirm the programming of that transmitter.
5. Repeat the previous step in order to program up to 4 transmitters.
6. Remove the scan tool.
7. Operate the transmitter functions in order to verify correct system operation.

I alos have 2003 express 3500...I tried the on/off on/off sequence but can't get the lock to get in the programming mode.

What is this scanner that you're talking about? is there any other easy without using any hardware? How much would the dealer charge to get the remote programmed?
