This garage door remote control is a replacement part and not an original accessory. We recommend that you check the device compatibility list below before purchasing.

[Frequency] 433.92 MHz, range: 50–100 m. Two buttons for controlling up to two open garage doors. The remote comes with batteries and is ready to use immediately – the perfect replacement. [Easy operation with instructions] Instructions included, easy to use. Lightweight and easy to carry, it can also be attached to your backpack as a decoration. 1. Compatible with Hörmann EcoStar 433.92 MHz rolling code remote controls. 2. Not compatible with the EcoStar BS and Liftronic II series. 3. High-quality replacement product, easy to program and use. Before programming, open the receiver from the garage door. Procedure: 1. Press the programming button. (On some receivers, the programming button must be held down.) 2. The LED on the receiver indicates that programming mode has started. 3. Press and hold a button on the new remote control for one second, then release it. 4. The LED on the receiver will light up or go out to indicate successful programming. 5. Wait a few seconds to exit programming mode. Programming is complete. Why doesn't the indicator light illuminate, or why does it only light up dimly, when I press the buttons on the illuminated remote control? This could be due to a weak or dead battery. If the indicator light still doesn't illuminate after replacing the battery, check the button or the remote control for damage. Caution! Are there any instructions from the programmer?
