Most of these replacement remotes use infrared (IR) line-of-sight control. At least one listing describes a radio-frequency (RF) remote, and some models advertise built-in voice search or voice-control features (separate from the wireless transport).
The listings consistently state the remotes use two AAA alkaline batteries. Batteries are required but typically not included with the remote.
These remotes commonly provide basic TV controls including power, volume, mute, and sleep. Several listings also mention input selection or consolidated volume/input controls so you can switch inputs and adjust volume alongside streaming controls.
Many remotes are pre-programmed for Roku devices and work out of the box after inserting batteries. In addition, several models include a learning feature that can copy functions from an original remote so you can add TV or audio controls (volume, power, etc.). Some listings emphasize no initial setup is required for Roku players while still offering learning for extra functions.
Listings show both 3-device and 4-device universal remotes. Some models advertise control of up to three A/V devices, while others are described as 4-device controllers — availability depends on the specific remote.
Many of the remotes are described as pre-programmed or ready to use out of the box — simply insert batteries. Others offer optional learning or programming to add TV or audio functions, so programming is optional for added features on those models.
Several remotes list compatibility with a wide range of Roku-enhanced TVs and explicitly include RCA among supported brands. Product details commonly note preprogramming or one-time programming for Roku TVs and other manufacturers; exact compatibility depends on the remote model.
