433MHz 4-Key Universal Garage Door Remote Control

Product Images

The product is a set of four universal remote controls, each with four buttons labeled A, B, C, and D. The available colors are yellow, red, green, and blue. These remotes are designed for cloning and duplicating signals for electric gates, garage doors, and other access control systems.

Visuals also show the remote control being used with a silver car, a hand holding a black remote with a keychain, and a close-up of a black remote with a keychain. Another image displays a red remote control being held, alongside a black remote control with a keychain. Additionally, there are images of garage doors, electronic rolling gates, and retractable doors, illustrating the application of these remotes.

A circuit board with four relays and a remote control are shown together. The circuit board has terminals labeled NO1, COM1, NC1, NO2, COM2, NC2, NO3, COM3, NC3, NO4, COM4, NC4. The remote control has four buttons labeled A, B, C, and D.

A white plastic enclosure for the circuit board is also depicted.

Instructions for Use

Clear Code:

1. Simultaneously press and hold the unlock and lock keys with two fingers. The LED light will flash rapidly 3 times in about 2 seconds.
2. Release one finger (keep the other pressed). Quickly click the loose button three times until the LED light flashes rapidly.
3. Release both fingers. Press any key on the remote. If the LED light goes off, the code is successfully cleared (all four keys are empty). If the light stays on, the code was not cleared successfully, and you need to repeat the clearing process.

Copy Code:

1. Place the original remote control and the cloned remote control as close as possible.
2. Simultaneously press the first key on both remotes. After about 2 seconds, the LED light on the cloned remote will flash quickly twice.
3. After one second, the indicator light will continue flashing. Release your fingers.
4. Press the key again. If the light stays on, the code from the original remote has been successfully copied to the cloned remote.
5. Repeat this process for the other keys (second, third, etc.). If the copy is successful, the cloned remote will function identically to the original.

Restore Code:

1. If you accidentally clear the copied code, simultaneously press the bottom two keys on the cloned remote.
2. The LED lights will flash quickly. Release after pressing any key, and the light will stay on. This indicates the code has been restored.

Important Note: Before using the cloned remote control, ensure the existing code on the remote has been cleared successfully.

Troubleshooting

Situation: Some keys control, others do not.

Use the clear and restore operation as follows:

1. Clear the code.
2. Copy the unsuccessful key again. No need to copy the rest of the buttons.
3. Clear the code again.
4. Restore the code. The previously uncopied keys will now be covered by new codes, while successfully copied keys remain. Repeat these steps if necessary until all keys are successfully copied.

• Vehicle central locking systems
• Garage doors
• Electronic doors
• Car sunroofs
• Heating systems
• And more...

Tips for Copying

1. Prerequisite: The original remote control must be functioning normally, have a compatible or identical chip, and operate at the same frequency (433MHz).
2. Compatibility: This remote can only copy fixed code, learn code chips, and some single-chip remote controls. It cannot copy two-way remotes, rolling code remotes, or single-chip encryption program remotes like HCS200, HCS201, HCS300, HCS301, etc.
3. Code Clearing: Ensure the existing code on the original remote is cleared before copying.
4. Power: Ensure both remotes have sufficient power. Maintain a close distance between the two remotes for optimal copying.
5. Copying Technique: If the copy distance is too close or at different angles, try pressing and holding the button on the original remote to send the signal normally, then press the button on the cloned remote to ensure the function is copied.
