How to Find the Remote Code for Your TCL Roku TV

I keep a TCL 4-Series (43S451) in the guest room and hand people a GE universal remote for it, so I've programmed a clicker to this TV more times than I can count. My honest take: the auto code-search finds a working code in about a minute and you never need to hunt for a number. The catch I always warn guests about — a universal code turns the TV on and changes volume, but it can't drive the Roku Home screen, so launching Netflix still needs the real remote or the app.

Below are four ways to make a remote control a TCL Roku TV, ordered by how most people actually reach this page: you have a universal or cable remote in hand and want the code. Each has exact steps and the real limit. If the remote you're programming is the TV's own and just won't respond, start with the TCL Roku remote not working checklist instead.

The 30-second test

Before you dig for a number, figure out which remote you're holding. The code route depends entirely on it. This quick check points you at the right method below.

1. 1Holding a store-bought universal remote (GE, One For All, RCA)? Use auto code-search (Method 1) or a brand code (Method 2).
2. 2Holding a cable or streaming remote (Xfinity, DirecTV, Spectrum)? Program it to TCL through your provider's setup (Method 3).
3. 3Just want full control — Home, arrows, search — without a code? A phone app over Wi-Fi (Method 4) gives you every button.
4. 4Not sure the TV is even a Roku model? Check for the purple Roku Home button on the boxed remote before you program anything.

Why there's no single TCL Roku code

Search "TCL Roku TV remote code" and you expect one magic number. There isn't one. Universal remote codes are specific to the remote's brand and model, not to the TV. A GE remote's TCL code is a different number from a One For All or an Xfinity code, because each maker builds its own code table. For how the 3-, 4-, and 5-digit code formats differ across remotes, see our TCL universal remote code (4-digit) guide.

So a code you copy from a random list only works if it came from your exact remote's manual. That's why the auto code-search below is the reliable path — it lets the remote find its own working code without you guessing a number. One more truth worth knowing up front: these codes travel over infrared and cover power, volume, and input only. Roku's menu, arrow pad, and app buttons need a Roku-certified remote or the phone app in Method 4.

Method 1: Run your remote's auto code-search

This is the fix that works even when you don't know the number. Auto code-search makes the remote cycle through every TV code it stores and send each one until the TV reacts. Nearly every universal remote — GE, One For All, RCA — has it, though the button names differ, so check that remote's manual for the exact keys.

1. 1Turn on your TCL Roku TV. Power the TV on with its own button or the boxed remote so the universal remote has a live target to test against. Auto code-search works by watching the TV react, so it must be on and showing a picture before you start.
2. 2Put the remote into code-search mode. Press and hold the universal remote's Setup or Program button until its indicator light stays on, then press the TV device key. The exact keys are printed in that remote's manual — GE, One For All, and RCA each label them differently.
3. 3Start the auto search. Point the remote at the TV and tap Power or Channel-Up once per second. The remote cycles through its stored TV codes one at a time, sending each brand's power command until one lands.
4. 4Stop when the TV responds. The moment the TV turns off (or changes channel), release the button right away. Overshoot and the remote moves past the working code, so watch the screen closely and stop on the first reaction.
5. 5Lock in the code. Press Setup or OK once to save the found code. Test power, volume, and input to confirm it stuck. If those work but the code drifts later, repeat the search — some remotes store the last matched brand.

Catch: auto search can stop on a code that only handles power, not volume. If that happens, keep searching for the next matching code, since one brand often has several entries. GE documents the search for its remotes in its universal remote code finder.

Method 2: Enter a TCL brand code by hand

If you already know the TCL code for your specific remote, entering it directly is faster than searching. The number lives in one of two places: the code list printed in that remote's manual, or the maker's online code finder. TCL is a listed brand in every major universal remote's table.

1. 1Find your remote's TCL code in its printed manual or the manufacturer's online code lookup — search by the remote's own brand and model, not the TV.
2. 2Press and hold Setup until the indicator light stays on, then press the TV device button.
3. 3Type the TCL code on the number pad. A steady light usually confirms it saved; a flashing light means the code was rejected — try the next TCL entry.
4. 4Test power, volume, and input. If any is dead, repeat with the next TCL code on the list, as brands often have several.

Catch: don't trust a code you found on an unrelated remote's list — it won't map to yours. Only your remote model's own code table is reliable, which is why Method 1's auto search is the safer bet when you're unsure.

Method 3: Program a cable or streaming remote

Provider remotes — Xfinity, DirecTV, Spectrum, Cox — can drive a TCL Roku TV's power and volume too, and they use their own setup, not a universal code list. Most now walk you through it in the provider's app or on-screen, so you rarely type a raw number anymore.

1. 1Open your provider's remote setup: the Xfinity app, DirecTV's on-screen remote menu, or the My Spectrum app all have a "program remote" flow.
2. 2Choose TV as the device and pick TCL as the brand when prompted. Voice remotes let you just say "TCL."
3. 3Follow the on-screen test — the setup sends a code and asks whether the TV reacted, then locks in the match.
4. 4If your remote is an older model with no app, hold its TV button until the light changes and enter the TCL code from the provider's website.

Catch: a provider remote controls the TV's power and volume but still can't open Roku's Home screen or apps — it's built to run the cable box, not Roku. Check your provider's official support site for the current TCL code, since these lists change.

Method 4: Skip the code with a phone app

Here's the route that needs no code at all — and gives you more than any universal one. A TCL Roku TV sits on your Wi-Fi, so a phone app talks to it over the network instead of infrared. That means you get the full Roku Home screen, the arrow pad, a keyboard, and search — not just power and volume.

1. 1Install a remote app: a no-account universal app like Smart TV Remote, or the official Roku mobile app. Both are free.
2. 2Put your phone on the same Wi-Fi as the TCL Roku TV — the app reaches the TV over the network, not infrared.
3. 3Open the app and tap your TV in the detected list. A universal app connects with no code; the Roku app may show a short pairing code on the TV to type in once.
4. 4Use the on-screen D-pad, Home, Back, volume, and keyboard exactly like the boxed remote — including everything a universal code can't reach.

Try the free universal app — Smart TV Remote connects to a TCL Roku TV over Wi-Fi with no account and no code. For the official option and its pairing code, see our free TCL Roku TV remote guide.

Catch: a phone app needs the TV awake on Wi-Fi, so it won't wake a set that's fully powered off at the wall the way an infrared code can. Roku documents the official app on its support site.

Which route fits your remote

The right method depends on the remote in your hand and how much control you need. Universal codes are quick but limited; a phone app does more but needs Wi-Fi. Match your situation to the row below.

My pick for most people: run the auto code-search if you just need power and volume from a clicker you already own, but install the phone app too so you always have the full Roku menu when the universal code falls short.
