1. Close all vehicle doors.
2. Insert Key into the ignition
3. Hold the power UNLOCK button on the driver'sdoor pane - continue to hold until instruced to release.
4. Perform steps 5 through 8 in a fairly rapid succession.
5. Turn the ignition to the ON postion (DO NOT CRANK)
6. Turn ignition OFF.
7. Turn ignition ON.
8 Turn ignition OFF.
9. Release the poser unlock button. The vehicle will lock and unlock the doors automatically.
10. Hold the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This may take up to 30 seconds.
11. Repeat the previous steps for each additional transmitter.

Can I get a flob off e bay and program it to my truck this way. The one I have is wore out.

Yes you can program second-hand fobs this way but make sure you get one for this year of vehicle. The programming instructions change periodically over the years. What year are these instructions for?
