RCA universal remote codes are model-specific. There is no single RCA code list that works with every RCA remote. An older RCU300 may require three-digit codes, an RCU404 may require four-digit codes, while a newer RCRN03BE uses five-digit codes. The same television brand can therefore have different valid codes depending on the remote model, revision, and device category.
The reliable process is simple: identify the exact model printed on the remote, open the matching RCA/VOXX manual or code list, enter a code using the procedure for that model, and test more than the power button. This guide explains how to do that without mixing incompatible code tables.
Before looking for an RCA remote code
Have these details ready:
- Remote model number: Look on the front, back, or inside the battery compartment. Examples include
RCRN03BE,RCRN03BZ,RCR503BR,RCR3273N,RCR412B,RCR4258N,RCRBB04GZ,RCRPST05SE,RCU300,RCU404, andRCU400. - Revision or code-list version: If a revision number is printed in the battery compartment or on the remote, match it to the manual. Different revisions may use different code databases.
- Device category: Choose the correct section—TV, SAT•CBL•STRM, DVD•VCR, digital converter, audio component, or another label actually present on your remote.
- Fresh batteries: Several RCA models, including the RCRN03BE and RCU300, use two AAA batteries. Install them according to the polarity markings.
- A powered-on device: Turn the TV, player, cable box, or other target device on manually before programming.
- A clear line of sight: Aim the remote at the device’s infrared sensor during setup and testing.
Use the code list supplied for the exact remote whenever possible. A generic internet table can be misleading if it does not identify the remote model, revision, device category, and source.

| RCA remote example | Typical code length | Important programming difference |
|---|---|---|
| RCRN03BE | Five digits | Uses the device key and POWER for direct entry. |
| RCU404 | Four digits | Uses CODE SEARCH followed by the component key. |
| RCU300 | Three digits | Uses CODE SEARCH followed by the component key. |
This is a format comparison, not a universal code table. Do not add zeros, remove digits, or substitute a code from another RCA remote. Entering a plausible-looking code with the wrong number of digits can fail or make the remote leave programming mode.
Fastest reliable method: direct code entry
Direct entry is the best first option when you have the code list for your exact RCA remote. The button sequence differs by model, so follow the section below only if it matches your remote.

Five-digit procedure for an RCRN03BE-style remote
- Turn the target device on manually.
- Find the device brand in the correct section of the RCRN03BE code list. Confirm that you are using the list for the RCRN03BE and its applicable revision, not another RCA remote.
- Press and hold the device key:
TV,SAT•CBL•STRM, orDVD•VCR. - While continuing to hold the device key, press and hold
POWER. - Enter the first five-digit code for the brand while still holding the device key.
- Release the device key. Watch the POWER indicator. Four flashes indicate an invalid code or a missed step; restart the procedure and try the next code listed for that brand.
- Aim the remote at the device and test multiple functions, not just power.
Depending on the code, some buttons may work while others do not. If the device turns off but volume, input, menu, navigation, or playback controls are missing, try the next five-digit code for the same brand.
Older three- and four-digit remotes
The RCU300 and RCU404 do not use the RCRN03BE sequence. Their manuals describe different CODE SEARCH procedures and different code lengths:
- RCU300: uses three-digit codes and the
CODE SEARCHkey followed by the appropriate component key. - RCU404: uses four-digit codes and the
CODE SEARCHkey followed by the appropriate device key.
Because the exact hold, indicator, and save steps vary, copy the button sequence from the manual for your model. Do not use the RCRN03BE five-digit procedure on an RCU300 or RCU404.
If you do not know the code: search methods
RCA remotes that support search may offer one or more alternatives to direct entry. The names and button combinations are model-specific.
Brand Code Search
Brand Code Search checks codes associated with the selected brand rather than scanning the entire database. It can be faster than a full search when the manufacturer appears in the remote’s code list.
Turn the device on, select the relevant device category, start Brand Code Search using the exact key combination in your manual, and stop and save the code when the device responds. A response is not necessarily proof that you found the best code, so test the important functions before keeping it.

Auto Code Search
Auto Code Search cycles through codes for the selected device category. On the RCRN03BE, the manual uses PLAY while the remote tests groups of codes. When the device responds, stop and store the working code as directed by the manual. That model’s search can time out after approximately two minutes.
Do not stop automatically at the first power response if the instructions tell you to continue or compare functionality. The first code that turns a device off may not provide the best menu, input, volume, channel, or playback control.
Manual Code Search
Manual search advances through codes one at a time. It is useful when the brand is missing from the list or direct entry does not work, but it can be slow.
The RCU300 manual warns that pressing ON•OFF may be necessary many times—possibly up to 200 presses—before a compatible code is found. When the device responds, press the model’s required save or enter key to store the code. The correct save button is not the same on every RCA remote.

How to test whether the code is actually suitable
Power control alone is not enough. With the remote aimed at the device, test the controls you expect to use:
- Power on and off
- Volume up, down, and mute
- Input or source selection
- Channel up and down
- Number keys
- Menu, guide, and exit
- Directional arrows and
OKorENTER - Playback, pause, stop, rewind, and fast-forward for DVD/VCR or media equipment
- Special device functions such as subtitle, aspect ratio, or streaming navigation when applicable
If only some functions work, return to the code list and try another code for the same brand. Universal remotes often support only the command set exposed by the selected code. Some brands or devices may not support menu access through that remote.
Retrieve and record the working code
Once you have a code that provides the best functionality, retrieve it using the code-retrieval procedure in your model’s manual and write it down. The RCU300 retrieves its three digits by entering code-retrieval mode and pressing number keys until the indicator blinks. The RCRN03BE has a corresponding five-digit retrieval process.
Keep the code with the remote or in a password manager or household notes. It can save time after a battery replacement, accidental reset, or reprogramming attempt.

Troubleshooting RCA universal remote programming
Nothing happens when I press a button
- Install fresh batteries and check their polarity.
- Press the correct device-mode key before testing.
- Make sure the target device is powered on.
- Aim directly at the device’s infrared sensor.
- Remove objects blocking the sensor and try from a shorter distance.
- Confirm that the remote’s indicator responds when you press a key.
For advanced diagnosis, an optional infrared remote tester can help determine whether the remote is emitting an IR signal, but it is not required for normal programming.
The code is rejected
Usually one of these problems is responsible:
- The code has the wrong number of digits for the remote.
- The code belongs to another RCA model or revision.
- The device category is wrong—for example, using a TV code while programming a DVD/VCR key.
- The brand or code was entered incorrectly.
- A required key was released too early or the wrong hold-and-press sequence was used.
Exit programming mode, restart the exact procedure from the matching manual, and try the next code in the correct brand section.
Power works, but the menu or navigation does not
Try another code for the same brand and repeat the full function test. RCA documentation notes that codes can provide different levels of functionality, and menu access is not supported for every brand.
The brand is not listed
Use Brand Code Search, Auto Code Search, or Manual Code Search if your remote supports it. A compatible code may still be found through a search even when the brand is absent from the printed list. Follow the model-specific instructions for starting and saving the search.
I have a TV/DVD or TV/VCR combo unit
Combo equipment may contain separately controlled TV and DVD/VCR portions. When the remote provides separate device keys, program the TV portion under TV and the player portion under DVD•VCR, using the corresponding code sections and procedures.
My remote is old but the device is new
Compatibility is not guaranteed. VOXX support material cautions that remotes older than approximately four years may not operate some newer components or may control only some functions. This is a support observation, not a universal expiration date: the exact remote, device, infrared support, and available code database determine the result.
Modern streaming sticks and some smart-home devices may also use Bluetooth, radio, HDMI-CEC, or another control system rather than accepting ordinary infrared commands. An older RCA infrared remote should not be assumed to control every streaming device simply because it controls a television.

When replacing the remote is the better option
If the remote has damaged buttons, a missing battery cover, unreliable infrared output, or no compatible code for a newer device, replacing it may be more practical than repeated searches. Choose an RCA universal remote based on the exact model, number of devices, device categories, required buttons, and compatibility information—not just the RCA name.

A generic RCA remote is not guaranteed to use the same codes or programming sequence as the remote it replaces. If you need a battery cover or other part, match the exact remote model before buying; covers and buttons are not interchangeable merely because both products carry the RCA brand.
How to publish or use an RCA code table safely
If you are copying codes into personal notes or creating a reference table, every entry should include:
- RCA remote model
- Revision or code-list version, when available
- Device category
- Equipment brand
- Code and digit length
- Source manual or official code list
Do not combine RCRN03BE, RCU300, RCU404, and other remote codes into one undifferentiated list. A table without those identifiers may cause readers to enter a valid code from the wrong database and conclude that the remote or device is defective.
Quick reference checklist
- Read the exact RCA remote model and any revision number.
- Obtain the matching RCA/VOXX manual and code list.
- Identify the correct device category.
- Install fresh batteries and turn the device on.
- Use direct code entry with the correct digit length.
- Try the next brand code if power or key functions fail.
- Use brand, auto, or manual search if direct entry does not work.
- Test power, volume, input, menu, navigation, and other important controls.
- Retrieve and record the final code.
Frequently Asked Questions
Are RCA universal remote codes the same for every RCA remote?
No. Codes and programming sequences vary by remote model, revision, device category, and code-list version. For example, the RCU300 uses three-digit codes, the RCU404 uses four-digit codes, and the RCRN03BE uses five-digit codes.

One-click scans. No signup required.
What should I do if an RCA code turns the device off but other buttons do not work?
Try the next code listed for the same brand, then test volume, mute, input, menu, navigation, channel, and playback functions. The first code that controls power may not provide the most complete command set.
Can I use a five-digit RCRN03BE code on an older RCU300 remote?
No. Use only the code length and programming procedure specified for the exact remote model. The RCU300 uses three-digit codes, while the RCRN03BE uses five-digit codes.
How do I program an RCA remote when my device brand is not listed?
Use Brand Code Search, Auto Code Search, or Manual Code Search if that feature is available on your model. Search controls and the save key differ between RCA remotes, so follow the matching manual.
Will an old RCA infrared remote control every new smart TV or streaming stick?
No. Compatibility is not guaranteed. Some newer equipment uses Bluetooth, radio, HDMI-CEC, or other control methods instead of ordinary infrared, and older remotes may control only part of a newer device’s functions.
The Bottom Line
The correct RCA universal remote code is the one listed for your exact remote model and device category—not simply any code associated with the equipment brand. Match the model and digit length, program it using the appropriate procedure, test several functions, and record the code that works best.
