Key Features

• Easy Code Cloning: Simply hold the new remote close to your original and press the matching buttons simultaneously — the LED confirms successful copying instantly.
• Code Backup & Recovery: Built-in memory lets you clear and restore saved codes quickly, so you're never locked out if you accidentally reset a button.

How to Use

1. Clear & Restore Codes

Hold the two upper buttons simultaneously. After the LED flashes briefly and goes off, continue holding for 2 seconds until the LED begins flashing again — this confirms the code has been cleared. To restore a recently cleared code, hold the two lower buttons simultaneously until the LED flashes after 3 seconds.

2. Copy / Clone a Button

Hold your original remote in one hand and the new duplicator in the other, keeping them as close together as possible. Press the matching button on both remotes at the same time. The LED on the duplicator will flash continuously, confirming that the button's code has been successfully learned. Repeat for each of the remaining buttons.

3. Code Recovery

If a code is accidentally cleared, press both lower buttons simultaneously. After the LED lights up (approximately 3 seconds) and then begins flashing rapidly, the previously stored code has been fully restored.

Frequently Asked Questions

Q: Will this 433MHz remote duplicator work with my existing garage door opener?

A: This universal remote is compatible with most 433MHz RF garage doors and electric gate systems that use fixed code, learning code, or rolling code protocols. Check your existing remote or opener unit for a 433MHz frequency rating to confirm compatibility before purchase.

Q: How many remotes can I clone onto the duplicator?

A: Each duplicator has 4 independent buttons, allowing you to clone up to 4 separate remote channels — for example, two garage doors and two gate openers — all from one convenient device.

Q: What happens if I accidentally clear the copied codes?

A: The built-in code recovery function lets you restore the most recently cleared codes. Simply hold the two lower buttons simultaneously for 3 seconds until the LED flashes rapidly to confirm successful restoration.

Q: What is the effective range of these remote controls?

A: In open space with no obstructions, these remotes typically operate reliably at distances of 50 to 100 metres, making them suitable for long driveways, large properties, and commercial gates.

Q: Is the 10-pack a good value for rental properties or businesses?

A: Absolutely. The 5-pack and 10-pack options offer excellent value for landlords, property managers, workshops, or any setting where multiple users need access. Each remote is individually cloned to your existing opener, so all units work independently.
