remote keyless entry programming

hi, i just got a new keyless remote for my 2005 chevy colorado w/c i bought online @ originalkeyless.com. the instruction they gave me wasn't working and i wasn't planning to visit any dealer to have it programmed (they charge too much for a 30 second job). i know it is just a simple touch of few buttons but i wanted to know the exact steps in programming the remote. thanks.

Have you tried this one

1. Close all vehicle doors.

2. Insert the key into the ignition.

3. Hold down the power UNLOCK button on the driver�s door panel-continue to hold down until instructed to release.

4. Perform steps 5 through 8 in fairly rapid succession.

5. Turn the ignition switch to the ON position (as far as you can go without starting the engine).

6. Turn the ignition switch to the OFF position.

7. Turn the ignition switch to the ON position.

8. Turn the ignition switch to the OFF position.

9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.

10. Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This step may take up to 30 seconds.

11. Repeat the previous step for each additional transmitter (including any existing transmitters).

If the previous doesn't work, go here.....
