Frequently Asked Questions

Q: Is this 433MHz remote compatible with my existing garage door or gate receiver?

A: This remote is compatible with any receiver that supports the EV1527 learning code protocol at 433MHz. Check your receiver's documentation or label for "EV1527" or "learning code" support. It is not a copy/clone-type remote, so it will not replicate fixed-code systems.

Q: Why doesn't my remote light up or respond when I press the buttons?

A: The built-in 2 × CR2016 3V batteries may have been drained during shipping if buttons were accidentally pressed in transit. Simply replace both batteries with fresh CR2016 cells and the remote will function normally.

Q: How many buttons/channels do I need for my application?

A: Choose based on how many independent functions you want to control. A 1-key (Model O) is ideal for a single door or device; 2-key (AB) suits open/close commands; 3-key (ABC) or 4-key (ABCD) models are great for controlling multiple gates, lights, or alarm zones from one remote.

Q: What is the effective range of this wireless remote?

A: In an open, obstacle-free environment, the remote can transmit up to 50 metres. In typical indoor or urban conditions with walls and obstructions, expect reliable operation at 15 metres or more.
