There is nothing worse than buying a used universal remote at a thrift store or garage sale, only to realize the instruction manual (and the code list) is missing.
If you don’t know the 4-digit code for your TV, and you can’t find it online, you aren’t out of luck. Almost every universal remote built in the last 20 years has a hidden feature called “Auto-Search” (sometimes called Code Search or Library Search).
Instead of you telling the remote what code to use, the remote scans its entire internal memory until it finds the right one.It takes a bit of patience, but it works on almost any device.
Here is how to run an Auto-Search correctly (and how to avoid the common mistakes people make).
How “Auto-Search” Actually Works
When you activate this mode, the remote sends a signal for “Code 0001,” then “Code 0002,” then “Code 0003,” and so on.
Your job is to act as the “Stop” button. You point the remote at the TV and wait. As soon as your TV reacts (usually by turning off or muting), you must lock in that code immediately.
Step-by-Step: The Search Method
Note: Steps vary slightly by brand (RCA, GE, One For All), but the logic is identical.
1. Turn on Your Device
Manually turn on the TV (or DVD player/Soundbar) you want to control. You cannot search for codes if the TV is off,because you won’t see it react!
2. Enter Search Mode
- Method A (Standard): Press and hold the “SETUP” (or “SET”) button until the red light stays solid. Then press the device button (e.g., “TV”). The light should blink once and stay on.
- Method B (Dedicated Button): If your remote has a button labeled “CODE SEARCH,” hold that down instead.
3. Start the Scan
Now, point the remote at the TV.
- Slow Pressing: Press the “POWER” button (or sometimes “Channel Up”) repeatedly. Press… wait 1 second…press… wait 1 second.
- Why wait? The remote needs time to send the signal. If you mash the buttons too fast, you will skip over the correct code.

4. The “Reaction” (Locking it in)
The moment your TV turns OFF, stop pressing immediately!
- Press the “ENTER” or “OK” button to save the code.
- The red light on the remote should turn off, indicating the code is saved.
Troubleshooting: “I Missed the Code!”
This is the most common problem. You got into a rhythm of pressing the button, the TV turned off, but your thumb hit the button one more time by accident. Now the remote has moved to the next code, and the TV won’t turn back on.
The Fix: Do not start over!
- If you missed the code, press the “Channel Down” (or “Reverse”) button once. This tells the remote to go backone step in the database.
- Press it slowly until the TV turns back ON.
- Once the TV turns back on, press “ENTER” to save.
Advanced Trick: “Code Retrieval” (The Blink Back)
So, you used Auto-Search and the remote is working. Great! But what happens if the batteries die and the remote resets?You don’t know what code it found.
Many remotes (especially RCA and GE) have a “Code Retrieval” feature that allows the remote to blink the code number back to you.
- Hold “SETUP” until the light stays red.
- Press the “TV” button.
- Press “SETUP” again briefly.
- Press the number 1. Count how many times the light blinks. (No blinks = 0).
- Press the number 2. Count the blinks.
- Press number 3 and number 4.
Example:
- Press 1: (Light blinks 2 times)
- Press 2: (No blinks)
- Press 3: (Light blinks 5 times)
- Press 4: (Light blinks 1 time)
Your code is 2051. Write this down!

Personal Experience: The “Volume” Test
I learned this the hard way: Sometimes Auto-Search finds a “partial match.” I once programmed a remote for a Vizio TVwhere the Power button worked, but the Volume didn’t. This is because different Vizio models share similar (but not identical) codes.
My Advice: After Auto-Searching, if the power works but other buttons don’t, start the search again. Don’t stop at the first code that works; keep going to find a better match later in the list.
Conclusion
Auto-Search is a lifesaver, but it requires patience. It can take up to 10 minutes to cycle through every code in the database. But once you find it, don’t forget to use the Code Retrieval trick to write it down for next time!
