Replacement Remote For Retrax Power Bed Cover On 2021 GMC Sierra 1500 AT4 Black Widow Edition
Updated 08/10/2026 | Published 08/06/2026
Question:
Hello, I purchased a used 2021 GMC Sierra 1500 AT4 Black Widow Military Edition and it has the Retrax Power bed cover. The bed cover remote was not included with purchase and I’d love for it to operate as of right now I cannot open the bed cover. That said, is there a replacement fob I can purchase? The serial number for the bed cover is: 21010470352002 If so, what is the price and how can I order? Thank you, Vandy H

Hey Vandy, thanks for reaching out, and thanks for providing that serial number. That really helps me track down the exact parts you'll need. Since the original remote is missing, the fix is to replace the remote receiver. The remotes are factory-paired to the receiver, so there isn't a way to purchase and program a standalone replacement remote.
For your Retrax power bed cover, you'll need the Replacement Remote Receiver for Retrax Powered Retractable Tonneau Covers Manufactured After 2017 # RTX89TR. It includes a new receiver and two new remotes, so you'll be back up and running with a matched system. This is the correct replacement for powered Retrax covers built after 2017, including the one on your 2021 GMC Sierra 1500 AT4.
What do you usually haul in your AT4? Tools, camping gear, or daily stuff?

Thanks for the response Jesse! I haul a variety of things when needed. I called in and was sold a replacement remote. It’s Item #RTX-F09-2029 priced at $47.99. Will this not work? If not, I will need to send it back to purchase the new receiver and remotes. It’s pricey so I hope the remote works. Ha! Thanks again and once I receive the new remote we’ll see if it works for me or not. Vandy
