Replacement remotes for DVD/Blu-ray players use infrared (IR) wireless transmission to send commands to the player.

Most replacement remotes arrive pre‑programmed and are ready to use—simply insert the required batteries and they should work without additional setup.

Typical replacement remotes measure about 1.0" (H) × 2.0" (W) × 6.0" (D) and weigh roughly 0.2 pounds for several models.

Battery requirements vary by model—some remotes use 2 AAA batteries while others use 2 AA batteries. Batteries are required but are listed as not included.
