The basic steps to pair a remote with your TV
Most remotes connect to a TV in one of two ways: infrared (IR), which requires a direct line of sight, or Bluetooth, which works through walls and around corners. Infrared remotes are older and simpler — you just point them at the TV and press buttons. Bluetooth remotes need to be paired first, meaning you tell the TV and remote to recognize each other, usually by holding a button for a few seconds.
If your remote came with your TV, it is already set up to work. If you bought a new remote or are connecting a universal remote, the pairing process takes less than a minute. The exact steps depend on whether your TV uses Bluetooth or infrared, and which brand you own.
Key Takeaways
- Infrared remotes work by pointing at the TV and need a clear line of sight; they do not need pairing.
- Bluetooth remotes work through walls and around corners but must be paired to your TV first by holding a button until a light blinks.
- Most TV remotes pair automatically when you press any button while holding the pairing button, or through your TV's settings menu under Bluetooth or Remote.
- If pairing fails, restart both the remote and TV, replace the remote batteries, and check that Bluetooth is turned on in your TV settings.
- Universal remotes work with most TV brands but may need a code entered or a mode selected to control your specific model.
How infrared remotes work and why they do not need pairing
An infrared remote sends invisible light pulses to a sensor on the front of your TV. The TV reads those pulses and performs the action — volume up, channel down, power off. Because infrared is one-way communication, the remote and TV do not need to know about each other beforehand. You can pick up almost any infrared remote and point it at almost any TV, and it will work to some degree.
The downside is that infrared requires a direct line of sight. If you point the remote at the wall next to your TV, or if someone stands between you and the TV, the signal does not reach. Infrared also does not work well in bright sunlight or if the sensor on your TV is dirty or blocked.
How Bluetooth remotes pair and why pairing matters
A Bluetooth remote uses radio waves instead of light, so it works through walls, around corners, and in any lighting. But because Bluetooth is two-way communication, the remote and TV must be introduced to each other first. This introduction is called pairing.
When you pair a Bluetooth remote, you are telling the TV "this is the remote I want to listen to" and telling the remote "this is the TV I want to control." Once paired, they remember each other. The next time you turn on the remote, it automatically connects to that TV without any extra steps.
Pairing usually takes 10 to 30 seconds. Most Bluetooth remotes have a dedicated pairing button on the back or underside. Hold that button until a light on the remote blinks or changes color — usually 3 to 5 seconds. Then press any button on the remote while pointing it at the TV. The TV should recognize it and show a confirmation message on screen.
Pairing steps for common TV brands
Samsung TVs: Press and hold the Pairing button on the back of the remote for 3 seconds until the LED blinks. The TV should prompt you on screen. If not, go to Settings > Remote and Accessories > Bluetooth Remote and select Pair Remote.
LG TVs: Hold the Pairing button (usually on the back) for 5 seconds. The remote LED will blink. Point the remote at the TV and press any button. LG TVs usually pair automatically when you press a button during the blinking phase.
Sony TVs: Go to Settings > Bluetooth Settings > Pairing Mode on your TV. Then hold the Pairing button on the remote for 3 seconds. The TV will search for the remote and confirm when paired.
Roku TVs: Most Roku remotes pair automatically the first time you use them. If pairing fails, go to Settings > Remotes and Devices > Bluetooth Devices and select Pair New Device. Then hold the Pairing button on the remote for 3 seconds.
Fire TV: Hold the Home and Back buttons together for 10 seconds until the LED flashes. The TV will search for the remote automatically.
What to do if your remote will not pair or stops working
If pairing fails, the most common cause is dead or dying batteries. Replace the batteries in your remote first, even if it seems to have power. Old batteries often have enough charge to show a light but not enough to complete pairing.
Next, restart both devices. Unplug your TV from the wall for 30 seconds, then plug it back in. Remove the batteries from the remote for 10 seconds, then reinsert them. Try pairing again.
If the remote still will not pair, check that Bluetooth is turned on in your TV settings. Go to Settings > Bluetooth or Settings > Connected Devices and make sure Bluetooth is enabled. Some TVs have Bluetooth turned off by default.
If your remote pairs but then stops working after a few days, it may have lost its connection. Most Bluetooth remotes reconnect automatically when you press a button, but if that does not work, repeat the pairing process. If a remote keeps losing connection, the batteries may be too weak or the remote may have a hardware problem.
Universal remotes and how to set them up for your TV
A universal remote is designed to work with multiple TV brands. Instead of pairing, most universal remotes use a code system. You enter a three or four-digit code that tells the remote which TV brand you own, and it downloads the correct commands.
To set up a universal remote, look for a Setup or Code button on the remote itself. Press and hold it until a light blinks. Then enter the code for your TV brand — these codes are printed in the remote manual or available on the manufacturer's website. Once entered, the remote should control your TV when ready.
Some newer universal remotes, like the Logitech Harmony, use Bluetooth and pair like any other Bluetooth remote. Others use infrared and work with any TV without setup. Read the manual that came with your universal remote to find out which method it uses.
Infrared vs. Bluetooth: which should you choose
If your TV came with a Bluetooth remote, use it. Bluetooth is more convenient because it works from any angle and through obstacles. If you are buying a replacement remote, check whether your TV supports Bluetooth before you buy. Most newer TVs do, but older models may only work with infrared.
Infrared remotes are cheaper and simpler, but they require a clear line of sight and can be unreliable in bright rooms. Bluetooth remotes cost more but work better in real-world conditions. If you have a choice, Bluetooth is worth the extra cost.
If you have both an infrared and a Bluetooth remote, you can use whichever one works best for your situation. Most TVs accept input from multiple remotes at once.
Frequently Asked Questions
Can I use any Bluetooth remote with any TV?
No. Bluetooth remotes are designed for specific TV brands or models. A Samsung Bluetooth remote will not work with an LG TV. However, infrared remotes are more universal — most infrared remotes work with most TVs, though some buttons may not function.
Why does my remote work sometimes but not always?
For infrared remotes, the sensor on your TV may be dirty or blocked. Clean the front of your TV with a soft cloth. For Bluetooth remotes, the connection may have dropped. Try restarting the remote by removing and reinserting the batteries, or go back through the pairing process. Weak batteries are also a common cause.
Do I need to pair my remote every time I turn on the TV?
No. Once a Bluetooth remote is paired, it stays paired. You only pair once, unless you reset the remote or pair it with a different TV. Infrared remotes do not pair at all — they work when ready when you point them at the TV.
What if my TV does not have a Bluetooth sensor?
Older TVs often have only infrared. You can still use an infrared remote, or you can buy a Bluetooth adapter that plugs into your TV's HDMI port or USB port. These adapters add Bluetooth capability to any TV.
Can I pair multiple remotes to the same TV?
Yes. Most TVs accept input from multiple Bluetooth remotes. You can pair a main remote and a backup remote, or let family members use their own remotes. Infrared remotes do not need pairing, so you can use as many as you want.
