The basic steps to pair your remote
Most TV remotes connect through one of two methods: infrared (IR), which requires a clear line of sight to the TV, or Bluetooth, which works through walls and around corners. The connection method depends on your remote type and TV model.
For infrared remotes, there is usually no pairing step — the remote straightforward needs to point at the TV's sensor (normally a small dark window on the front or bottom edge). For Bluetooth remotes, you will need to put the TV and remote into pairing mode so they recognize each other. Check your TV's manual or the sticker on the remote's back to see which type you have.
Key Takeaways
- Infrared remotes need a clear line of sight to the TV's sensor and do not require pairing, while Bluetooth remotes work through obstacles but must be paired once.
- To pair a Bluetooth remote, hold the pairing button (usually on the back) for 3 to 5 seconds until the remote's light blinks, then select it from your TV's settings menu.
- If your remote does not respond, replace the batteries first, then check that nothing is blocking the infrared sensor or that Bluetooth is turned on in your TV settings.
- Some smart TV remotes control apps and streaming services directly, while basic remotes only change channels and volume — your TV model determines which features work.
Pairing a Bluetooth remote to your TV
Bluetooth remotes are common on newer smart TVs and require a one-time pairing. Start by turning on your TV and opening the Settings menu. Look for a section called Remote, Bluetooth Devices, or Accessories — the exact name varies by brand (Samsung calls it Remote Management, LG calls it Bluetooth Devices, Roku calls it Remotes & Devices).
While the TV settings are open, hold down the pairing button on the back of your remote for 3 to 5 seconds. You will usually see a light blink on the remote or a message on the TV screen saying it is searching for devices. When your remote appears in the list on your TV, select it to complete the pairing. The remote should now work without pointing it at the TV.
If the pairing does not complete, make sure your TV's Bluetooth is turned on in the same settings menu. Some TVs have Bluetooth disabled by default. Also check that you are holding the pairing button long enough — many people release it too early.
Using an infrared remote without pairing
Infrared remotes do not need pairing because they send signals directly to the TV's sensor, similar to how a garage door opener works. straightforward point the remote at the TV and press a button. The sensor is usually a small dark window on the front bezel or bottom edge of the TV.
Infrared signals travel in straight lines, so anything blocking the path — a soundbar, a picture frame, or even your hand — can prevent the remote from working. If your remote stops responding, move closer to the TV, point it more directly at the sensor, and try again. Infrared remotes also work better in rooms with less bright light, since sunlight and bright lamps can interfere with the signal.
Troubleshooting when your remote does not respond
The first step is always to replace the batteries. Most remote problems are caused by weak or dead batteries, and this takes 30 seconds. Open the battery compartment on the back of the remote, remove the old batteries, and insert new ones with the + and − sides facing the correct direction (usually marked inside the compartment).
If a new battery does not fix the problem, check whether your remote is infrared or Bluetooth. For infrared remotes, make sure nothing is blocking the sensor on the TV and that you are pointing the remote directly at it. For Bluetooth remotes, go back to your TV's settings and check that Bluetooth is turned on. If it is off, turn it on and try pairing the remote again.
If your Bluetooth remote still does not pair, try "forgetting" it from the TV's settings and pairing it again from scratch. Most TV settings menus have an option to remove or unpair devices. Select your remote from the list and choose Remove or Forget, then repeat the pairing steps above.
Connecting a replacement or second remote
If you are replacing an old remote or adding a second one, the process is the same as pairing a new remote. For Bluetooth remotes, follow the pairing steps in the section above. For infrared remotes, there is nothing to do — any infrared remote designed for your TV model will work when ready.
If you are buying a replacement remote, check your TV's model number (usually on a sticker on the back) and search for the correct remote online. Using the wrong remote model may not work at all, or may only control basic functions like power and volume. TV manufacturers sell official remotes, and third-party remotes are also available at lower cost — both types work the same way once paired.
Understanding what your remote can control
Basic remotes control only power, volume, and channel selection. Smart TV remotes often have additional buttons for apps, streaming services, and voice control. If your remote has a microphone button or a button labeled with a streaming service name (Netflix, Disney+, Prime Video), pressing it will open that app or search within it.
Some smart remotes also control your TV's picture settings, input selection, and menu navigation. The buttons available depend on your TV brand and remote model. If you are unsure what a button does, check the manual that came with your TV or search your TV model number plus "remote guide" online.
Frequently Asked Questions
Why does my infrared remote work sometimes but not other times?
Weak batteries are the most common cause. Replace them first. If that does not help, check that nothing is blocking the TV's infrared sensor and that you are pointing the remote directly at it. Bright sunlight or very bright room lights can also interfere with infrared signals, so try dimming the lights and testing again.
Can I use any remote with my TV?
No. Infrared remotes are usually brand-specific — a Samsung remote will not work with an LG TV. Bluetooth remotes must be paired to your specific TV. You can use a universal remote designed to work with multiple brands, but you will still need to program it for your TV model first.
Do I need to pair my remote every time I turn on the TV?
No. Once a Bluetooth remote is paired, it stays paired until you unpair it or reset the TV. Infrared remotes do not require pairing at all. You only need to pair again if you reset your TV, replace the remote, or deliberately unpair it.
What if my TV does not have a Bluetooth settings menu?
Your TV may not support Bluetooth remotes, or Bluetooth may be disabled. Check your TV's manual to see if Bluetooth is a feature. If it is, look in Settings under Remote, Accessories, or Connected Devices. If you cannot find it, your TV may only work with infrared remotes.
Can I use my phone as a remote instead?
Many smart TVs have apps that let you control them from your phone over WiFi or Bluetooth. Search your TV brand name plus "remote app" in your phone's app store. The app usually requires your phone and TV to be on the same WiFi network, and it works best for navigating menus and apps rather than quick channel changes.
