Have you ever bought a universal remote, tried every single code in the manual, and still found that the “Menu” or “Input” buttons won’t work? It is one of the most frustrating experiences in home theater setup.
Most people don’t realize there are two types of universal remotes: Pre-Programmed and Learning.
If you are struggling with standard codes, you might have a Learning Remote (like the popular L336, Chunghop, or higher-end Logitech models). These remotes don’t just guess codes from a database; they can actually “learn” or copy the signal directly from your old remote.
In this guide, I will walk you through exactly how to clone your TV or DVD remote signals to a universal learning remote.
What is a “Learning” Remote?
Before we start programming, it is important to understand if your remote actually has this feature.
- Standard Universal Remote: You enter a 4-digit code (e.g., 1024) and the remote uses a preset internal database to talk to your TV. If your TV brand isn’t in that database, you are out of luck.
- Learning Universal Remote: This remote has an IR (Infrared) receiver built into the front. It can “watch” your old remote send a signal and record that signal to its own memory.
Key Requirement: To use a learning remote, you must have the original remote available and it must have working batteries. If you lost your original remote entirely, this method will not work for you (you will need a pre-programmed remote instead).
Step-by-Step Guide: How to Copy Remote Signals
The process is slightly different for every brand, but the “Head-to-Head” physics are the same for all IR learning remotes.
1. Prepare Your Environment
Lighting matters. Infrared signals are light beams invisible to the human eye. Bright sunlight or fluorescent lighting can interfere with the recording process.
- Find a dimly lit room away from direct windows.
- Place both remotes on a flat, stable table. Do not hold them in your hands, as shaking can ruin the signal transfer.
2. The “Head-to-Head” Alignment
Place your Original Remote and your Learning Universal Remote on the table facing each other. The LED bulbs at the top of the remotes should be pointing directly at each other.
- Distance: They should be about 1 to 2 inches (2-5 cm) apart. Too close, and the signal “blows out” the receiver. Too far, and it won’t pick it up.

3. Enter “Learning Mode”
On your universal remote (the one doing the learning), you need to trigger the recording state.
- Usually, you press and hold the “SET” or “LEARN” button for about 3-5 seconds.
- The small LED light on the remote will change from a quick flash to a solid bright red (or amber) light. This indicates it is listening for a signal.
4. Teach the Buttons
Now we map the keys one by one. Let’s say we want to program the “Power” button.
- Select the Key to Learn: On the Universal Remote, press the “Power” button once. The indicator light should start flickering slowly. It is saying: “Okay, I’m ready to record the Power signal. Send it to me now.”
- Send the Signal: On your Original Remote, press and hold the “Power” button. Keep holding it until the light on the Universal remote flashes quickly or turns solid again.
- Confirm: This quick flash usually means “Signal Received.”
Repeat this process for Volume Up, Volume Down, and Input.
5. Save and Exit
Once you have copied all the buttons you need, you must save the data.
- Press the “SET” or “LEARN” button on the universal remote one last time to exit learning mode.
- The LED light should turn off.
Troubleshooting: Why Won’t My Learning Remote Work?
I have programmed dozens of these devices, and here are the most common reasons they fail, which manuals rarely tell you.
The “Clean Signal” Issue
If your original remote has low batteries, it sends a weak or “dirty” IR signal. The learning remote might reject it.
- Fix: Put brand new alkaline batteries in the original remote before you start teaching.
The Button Protocol Confusion
Some buttons on modern remotes (especially for Samsung or LG TVs) send a “toggle” signal—one code for “On” and a different code for “Off,” even though it’s the same button. Cheap learning remotes sometimes struggle to learn these complex toggle codes.
- Fix: Try pressing the button briefly instead of holding it down during the learning step.
IR vs. RF Interference
This is a critical distinction. Learning remotes can only copy Infrared (IR) signals. They cannot copy Radio Frequency (RF) or Bluetooth signals.
- If you have a remote for a Roku Stick, Amazon Firestick, or a PS4/PS5, these use Bluetooth/RF. You cannot clone these to a standard L336 or Chunghop learning remote because they do not use light to communicate.
Note: If you are trying to program a specific brand like Grundig or Tzumi, check out my specific guides here: [Link to your Grundig article] and [Link to your Tzumi article].
Personal Experience: The “L336” Test
I recently tested this method on a generic “L336 Smart Remote” (a very common 3-in-1 model found on Amazon). I found that if I held the original remote button down for too long, the L336 would get confused. The sweet spot was a short, sharp press of about 1 second.
Also, I noticed that cleaning the plastic LED cover on the front of my old remote with a microfiber cloth helped the signal transfer significantly. Dust can block the infrared beam just enough to cause errors.
Conclusion
Learning remotes are the ultimate backup plan when standard universal codes fail. While the setup takes a few minutes longer than just punching in a code, the result is a custom remote that has exactly the buttons you need—no more, no less.
If you have tried the steps above and the light still won’t blink, double-check your batteries and ensure you aren’t trying to copy a Bluetooth remote!
