The basic pairing process
A universal remote connects to your TV through one of two methods: infrared (IR) pairing, which requires line-of-sight and a direct signal, or Bluetooth pairing, which works through walls and doesn't need the remote pointed at the TV. Most universal remotes use infrared by default because it's simpler and requires no setup — you just need the right code for your TV model. Bluetooth remotes require an initial pairing step where you hold a button to make the remote discoverable, similar to pairing wireless headphones.
The first step is identifying which type of remote you have. Look at the top of the remote: if you see a small dark lens, it's infrared-only. If the remote has a Bluetooth symbol (usually a small stylized "B") printed on it or mentioned in the manual, it supports Bluetooth pairing. Some newer universal remotes do both, but they default to infrared for most devices.
Before you start, locate your TV's model number. You'll find it on a sticker on the back of the TV, on the bottom bezel, or in the TV's settings menu under System Information or About. Write it down — you'll need it if you're setting up an infrared remote.
Key Takeaways
- Infrared remotes need your TV's model number and work by pointing at the TV; Bluetooth remotes need an initial pairing step but work through walls.
- Most universal remotes come with a code list or online database where you enter your TV brand and model to find the correct code.
- If the code doesn't work on the first try, the remote usually has an auto-search feature that cycles through codes until one works.
- Bluetooth pairing typically involves holding a setup button for three to five seconds until a light blinks, then confirming the pairing on your TV.
- Test the remote with basic functions like power and volume before assuming it's fully connected.
Setting up an infrared remote with a code
Infrared remotes work by sending a specific signal pattern that your TV recognizes. Universal remotes store hundreds of these patterns, organized by TV brand and model. To load the right pattern into your remote, you need to enter a code — usually a three or four-digit number that corresponds to your TV.
Start by finding the code for your TV. Most universal remotes come with a printed code list organized by brand. Look up your TV's brand (Samsung, LG, Sony, Vizio, TCL, and so on) and then find your specific model number in that section. Write down the code. If you don't have the printed list, visit the remote manufacturer's website — Logitech, GE, and RCA all maintain searchable code databases online. Enter your TV brand and model, and the site will display the code or codes that work.
Once you have the code, sit in front of your TV with the remote pointed at it. Most universal remotes have a setup button or mode button — check your manual for the exact name, as it varies by brand. Press and hold this button until a light on the remote blinks or changes color, indicating it's in programming mode. Then enter the code using the number pad on the remote. The light will blink again or turn off when the code is accepted. Press the power button on the remote to test: if your TV turns off, the code worked.
If the power button doesn't work, the code may be incomplete or incorrect. Try the next code listed for your TV brand and repeat the process. Some TV models have multiple codes because different remote versions were sold over the years.
Using auto-search when you don't have the code
If you can't find your TV's model number or the code list doesn't include your model, most universal remotes have an auto-search feature that cycles through codes automatically until one works. This takes longer than entering a code manually, but it works for nearly every TV made in the last twenty years.
Enter programming mode the same way you would to enter a code manually — press and hold the setup or mode button until the light blinks. Instead of entering a number, press a button like the right arrow or a dedicated "search" button. The remote will begin cycling through codes, sending a signal to your TV every few seconds. Watch your TV: when it turns off, the correct code has been found. Press the power button again to turn the TV back on, confirming the match. Then press the setup button again to exit programming mode and save the code.
Auto-search can take five to ten minutes because there are hundreds of codes to cycle through. Stay in the room and keep the remote pointed at the TV so you don't miss the moment your TV responds. If your TV turns off and back on repeatedly, the remote may be cycling too fast for you to catch it — in that case, press any button to pause the search, then manually enter codes from your list one at a time.
Pairing a Bluetooth remote
Bluetooth remotes require an initial pairing step that links the remote to your specific TV. This is different from infrared, where any universal remote with the right code works with any TV of that model. With Bluetooth, the remote and TV need to recognize each other first.
Start by putting your TV into pairing mode. This is usually done through the TV's settings menu — look for Bluetooth, Remote, or Accessories settings. The exact path varies by brand: Samsung TVs often have it under Settings > Sound > Speaker Settings > Bluetooth Audio, while LG TVs use Settings > All Settings > Sound > Sound Out > Bluetooth. Consult your TV's manual if you can't find it. Once you've enabled Bluetooth pairing mode, your TV will wait for a remote to connect, usually for about two minutes.
While the TV is in pairing mode, put your remote into pairing mode as well. Most Bluetooth remotes have a dedicated pairing button, often labeled "Pair" or "Connect," or you may need to hold the setup button for three to five seconds until a light blinks. Check your remote's manual for the exact method. Once the light blinks, the remote is broadcasting its presence to nearby devices. Your TV should detect it and display a confirmation message on screen. Select "Pair" or "Connect" using your TV's existing remote or on-screen menu. The light on your Bluetooth remote will stop blinking once the pairing is complete.
Test the remote by pressing the power button or volume controls. If the TV responds, the pairing worked. If nothing happens, the pairing may have timed out — repeat the process, making sure both the TV and remote are in pairing mode at the same time.
Troubleshooting when the remote doesn't respond
If your remote isn't controlling the TV after you've entered the code or completed pairing, start with the simplest fixes. Check that the batteries are fresh — remove them, wait ten seconds, and reinsert them. A weak battery won't send a strong enough signal, especially with infrared remotes. If you're using an infrared remote, make sure you're pointing it directly at the TV's sensor, usually located on the front bezel. Infrared signals bounce off walls and furniture, but they work best with a clear line of sight.
For infrared remotes, try a different code from the list for your TV brand. Some TV models have multiple codes because different remote versions were sold, or because the TV's firmware was updated. Cycle through two or three codes before assuming the remote is broken. For Bluetooth remotes, try unpairing and re-pairing: go into your TV's Bluetooth settings, find the remote in the list of paired devices, and select "Forget" or "Remove." Then repeat the pairing process from the beginning.
If the remote works for some buttons but not others, the code or pairing may be incomplete. This is common with older TV models where not all button functions are supported by the universal remote. Test the essential buttons — power, volume, and channel up/down. If those work, the remote is paired correctly, and missing buttons are straightforward not programmed for your TV model. Some universal remotes allow you to manually program individual buttons, but this requires consulting the remote's manual.
When to use a TV's native remote instead
Universal remotes work well for basic functions like power, volume, and channel changing, but they often don't support advanced features like smart TV apps, voice control, or picture settings. If you need to access Netflix, adjust picture quality, or use voice commands, you'll need your TV's original remote or the TV's mobile app.
Some newer smart TVs have mobile apps that let you control the TV from your phone — Samsung SmartThings, LG ThinQ, and Roku all offer this. These apps often work better than universal remotes for navigating menus and launching apps. If your TV supports this, read the app and connect it to your TV through your home WiFi. This gives you the functionality of the original remote without needing to keep track of a physical device.
If you've lost your TV's original remote entirely, check whether your TV model's remote is still available for purchase. Most TV manufacturers sell replacement remotes online or through retailers, and they're usually cheaper than a universal remote. A native remote will always have better compatibility with your specific TV than a universal one.
Frequently Asked Questions
Do I need to reprogram the remote if I move it to a different TV?
Yes, if you're using an infrared remote. Each TV brand and model has its own code, so you'll need to enter the new code for the second TV. Bluetooth remotes need to be unaired from the first TV and then paired with the second TV through its Bluetooth settings. Universal remotes are designed to work with multiple TVs, so this is a normal part of using them.
Can a universal remote work with a TV that's turned off?
No. Infrared and Bluetooth signals only work when the TV is powered on and its receiver is active. If your TV is completely off, the remote can't turn it on. This is why many people keep their TV's original remote as a backup — if the universal remote batteries die, you'll need the original to power on the TV.
Why does my infrared remote sometimes stop working even though the batteries are fine?
Infrared sensors can be blocked by dust, pet hair, or objects placed in front of the TV. Clean the sensor lens on the front of your TV with a soft, dry cloth. Also check that nothing is blocking the path between the remote and the TV. If the sensor is damaged, you may need to use a Bluetooth remote or replace the TV's receiver board.
Can I use a universal remote with a TV that doesn't have a model number?
If you can't find a model number, try using the auto-search feature on your universal remote. This cycles through codes until one works, so you don't need to know the exact model. If auto-search doesn't work, contact the TV manufacturer with a photo of the TV — they can often identify the model from its appearance and provide you with the correct code.
What's the difference between a "learning remote" and a universal remote?
A learning remote can record signals from your TV's original remote by pointing both remotes at each other. This is useful if your TV model isn't in the universal remote's database. A standard universal remote uses pre-programmed codes. Learning remotes are more flexible but require more setup time, while universal remotes are faster if your TV's code is available.
