According to the website CodesForUniversalRemotes.com, the most common three-digit Toshiba codes are 013, 049, 089 and 105. If the TV requires four-digit codes, the most common ones are 0260, 0358, 0394 and 0924. The codes vary between television models.
Remote codes are necessary to program universal remotes to work with a number of devices like, TVs, DVD players and stereos. Typically, the remote is programmed by holding down the button for the desired device on the remote and then entering in the provided code. If the correct code is entered, the volume, power-on and power-off, and channel-changing functions for the devices can be controlled by one remote.
