Introduction
This manual provides comprehensive instructions for the setup, operation, and maintenance of your Micro Four Buttons Fix Code Learning Remote Control. This universal key-chain remote is designed to learn directly from existing fixed code remotes, allowing you to consolidate up to four different remotes into one device. It operates within a frequency range of 250Mhz-500Mhz and is compatible with various fixed code remote controls for applications such as garage doors, security gates, car alarms, and home door locks.
Note: This device is designed for fixed code remotes only and cannot clone rolling code (hopping code) remotes.
Safety Information
- Keep the device out of reach of children.
- Do not expose the remote to extreme temperatures, direct sunlight, or moisture.
- Do not attempt to disassemble or modify the remote control, as this will void the warranty and may cause damage.
- Ensure proper battery polarity when replacing batteries.
- Dispose of old batteries responsibly according to local regulations.
Product Overview
The Micro Four Buttons Fix Code Learning Remote Control features a compact design with four programmable buttons. Each button can be assigned to a different fixed code signal.

Figure 1: Front view of the Micro Four Buttons Fix Code Learning Remote Control. It is a black, rectangular device with four white, circular buttons arranged vertically on its face. A small green LED indicator is visible above the top button. A metal keychain clip is attached to the side.
- Four Programmable Buttons: Each button can store a unique fixed code signal.
- LED Indicator: Provides visual feedback during programming and operation.
- Compact Design: Easily fits on a keychain.
- Glow-in-the-Dark Buttons: For improved visibility in low-light conditions.
Setup and Programming
Before using your new remote, you must program it to learn the signals from your existing fixed code remotes. Ensure your existing remote is functional and has a fresh battery.
1. Clearing Existing Codes (Important!)
It is essential to clear any pre-existing codes from the learning remote before programming. This ensures a clean slate for new signals.
- Press and hold the top two buttons (Button 1 and Button 2) simultaneously on the learning remote.
- Keep holding until the LED indicator flashes rapidly three times, then stops.
- Release both buttons.
- Press any button on the learning remote. If the LED does not light up, the codes have been successfully cleared. If the LED lights up, repeat the clearing process.
2. Programming a Button
Follow these steps to program each button on your new learning remote with a signal from your original fixed code remote.
- Place the learning remote and your original fixed code remote side-by-side, as close as possible (ideally touching).
- Press and hold the button on the learning remote that you wish to program (e.g., Button 1). The LED will flash slowly.
- While still holding the button on the learning remote, press and hold the corresponding button on your original fixed code remote.
- The LED on the learning remote will flash rapidly three times, then turn solid, indicating successful learning.
- Release both buttons.
- Test the newly programmed button on the learning remote. If it works, proceed to program other buttons. If not, repeat the programming process, ensuring the remotes are close and the original remote's battery is strong.

3. Restoring Previously Cleared Codes
If you accidentally cleared codes and wish to restore them (only if they were previously saved), follow these steps:
- Press and hold the bottom two buttons (Button 3 and Button 4) simultaneously on the learning remote.
- Keep holding until the LED indicator flashes rapidly three times, then stops.
- Release both buttons. The previously stored codes should now be restored.
Operating the Remote
Once programmed, operating the learning remote is straightforward.
- Identify the button on the learning remote that corresponds to the function you wish to activate (e.g., garage door opener, gate opener).
- Point the learning remote towards the receiver of the device you wish to control.
- Press and hold the corresponding button on the learning remote until the desired action occurs (e.g., garage door opens/closes).

Maintenance
- Cleaning: Wipe the remote with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: The remote uses a 23A Alkaline battery. When the remote's range decreases significantly or the LED indicator becomes dim, it's time to replace the battery. To replace, carefully open the remote casing (refer to Figure 2 for potential access points, though specific instructions for opening may vary slightly by unit) and replace the old battery with a new 23A Alkaline battery, ensuring correct polarity.
- Storage: Store the remote in a cool, dry place away from direct sunlight and extreme temperatures.
