Remotes with the same frequency are not compatible, if the shape, the color of keys, color of the box is different. This applies even if they are from the same brand. They do not have the same electronics!
Please note: please do not confuse this model, which has a rare frequency of 868.35 MHz, with the model CAME TOP432NA, which is far more common and which looks exactly the same except for the colour of the buttons. The colour of the buttons is related to the frequency for this model. Remote controls with different frequencies are not compatible.
