Hi Cody; to reprogram the Replacement Key Fob - Powertrax Retractable Tonneau Covers - Serial Number 1701 or Higher # RTX36TR follow these steps:

1. Disconnect power to the cover’s receiver for about 2 minutes so it resets.
2. Reconnect power to the receiver.
3. Press and hold the “STAR” (light) button on the key fob for ~1 second. This clears the receiver’s internal code.
4. Immediately after that, press and hold both the “C” (Close) and “O” (Open) buttons together. Continue holding until the key fob’s small indicator light begins flashing.
5. Once the light flashes, release the buttons. The fob should now be paired/programmed to the cover.

How do you do step #1? How do I find out is its 1701 or higher?

@Dennis disconnect the wiring harness near the canister. Look under the last panel near the tailgate for a sticker with the serial number.
