Getting Your Onn Remote to Work With Your TV Without Losing Your Mind
If your Onn remote stopped responding or started doing weird things after a power outage, you probably just need to reprogram the code. These remotes use a set of industry-standard codes that map to different TV brands. The process itself takes about five minutes if you're working with a straightforward setup, but it can drag to twenty or more depending on how stubborn your particular TV is being. Here's how it actually works. Press and hold the Setup button on the Onn remote until the LED blinks twice, then enter the four-digit code for your TV brand. The light should blink once to confirm. Test the power button. If it works, you're done. If it doesn't, you move to the next code in the list and repeat. Most people give up after three or four tries because they don't realize there are typically 10 to 20 codes listed for each brand, and the first one is only right about thirty percent of the time based on my experience. I ran into a situation recently where I was programming an Onn remote for a Samsung QLED and every single code in the official list failed. The remote would power the TV on but not off, which is a common partial-match problem. What actually worked was searching for a code from a user-submitted database, finding code 0752, and then manually stepping through it. The key is that once any code partially works, you can do a manual search to fine-tune it. Press and hold Setup, press Power repeatedly until the TV turns off, then press OK to lock it in. This manual method fixed maybe a quarter of the "stubborn" remotes I've dealt with over the years.
Common code lists by brand: Samsung: 0752, 0078, 0178, 0007, 0160, 0291, 0156, 0112 LG: 0453, 0178, 0010, 0156, 0752, 0078, 0117, 0243
Sony: 0102, 0366, 0401, 0245, 0100, 0200, 0098, 0360 TCL: 0156, 0752, 0078, 0178, 0007, 0243, 0112, 0453 Roku TV (built-in): 0156, 0752, 0112, 0078, 0243, 0007
Get the Full Details
These codes come from the original IR command set that Onn licensed, and they're available on the Onn support page, various third-party databases, and printed sheets that sometimes come in the packaging. The official list is the most reliable starting point because it's been tested against the most common firmware revisions. There's a detail most people miss about these remotes. The Onn remote is a universal remote that ships with a broad code library, but it doesn't always store codes in the same memory slot across different hardware revisions. Some versions of the remote use a two-step process where you enter the brand code, then the TV type code. If you enter a brand code and nothing happens at all, try holding Setup longer, around five seconds, to see if it enters an extended programming mode. This variation exists because Walmart has sourced the same remote design from at least three different manufacturers over the years, and the firmware differs slightly between them. Another thing beginners consistently get wrong is assuming the code list is exhaustive. It isn't. There are obscure TV models, especially from brands like Vizio and Hisense, where the listed codes cover maybe sixty percent of units on the market. For those, the auto-search method is your only real option. Hold Setup, press Power once to send the initial code, then press Channel Up repeatedly. Every time the TV responds, note the code. This usually takes about two minutes but requires you to be watching the TV directly because the response can be delayed by a second or two.
The main limitation of this approach is that Onn remotes only handle IR commands. If your TV is a newer model that primarily uses Bluetooth or proprietary wireless protocols for things like voice control or menu navigation, the Onn remote won't touch those functions. You'll get power, volume, and channel basic functions, and that's it. For a basic setup this is fine, but if you're trying to replace a smart remote on a high-end TV, you're going to be frustrated quickly. I also found that some users report the remote working perfectly after a code entry but then randomly losing the setting. This is almost always a battery issue. The Onn remote draws a noticeable amount of current during code storage, and cheap alkaline batteries can sag under that load enough to corrupt the stored code. Replacing with name-brand alkalines or recharging the remote if it supports it usually resolves this. I've seen this fix about half the "my remote kept forgetting the code" cases I've encountered. If you're downloading a code list, make sure it matches your remote's model number. The Onn lineup includes at least two distinct remote designs, and the code entry sequence between them differs in the Setup button hold duration. The longer-bodied remote with the wider button spacing typically uses a one-second hold, while the compact version often needs two to three seconds. Wrong hold duration means the remote enters a different mode entirely and you'll spend twenty minutes punching in codes that never work because you never actually entered programming mode in the first place.
The whole process from start to finished TV should take no more than ten to fifteen minutes for most people. If you're past twenty minutes and still nothing, you're either dealing with a non-IR TV, a battery problem, or a defective remote. In that case, a dedicated IR blaster or switching to the TV manufacturer's app as a temporary control solution is probably worth the ten to fifteen dollar investment rather than continuing to cycle through codes.
