Versatile: The programmable radio remote control from Unitronic not only opens and closes garage doors at the touch of a button, but also roller shutters and compatible lighting, alarm and irrigation systems. Two programmable buttons: The handy model is suitable for up to two receivers with a fixed code. This means you can control two garage doors with just one radio remote control. The radio key is therefore also an ideal replacement if the original remote control cannot be found. Particularly great: Programming the original remote control is quick and easy. Compact format: The programmable radio remote control has a compact design and fits in any trouser pocket. This means you always have the radio remote control to hand. The snap hook is also particularly practical, allowing you to easily attach the model to your key ring. Set of 2 wireless hand-held transmitters: Versatile use for end devices with fixed code.
