Replacement remotes will not work without a firmware update
We have used several of these on our SB3820 soundbar. All remote controls will stop working after some time until the firmware is updated. Search the Internet for "Firmware Remote Control Update Firmware update for S3821w-C0 and S3820w-C0 Sound Bar". The Vizio website has a video tutorial and a place to download the .bin file used to update the firmware onto a USB stick. This firmware is NOT available on the Vizio firmware download site. Worked for us!
